Science Experiments at Home that take Less than 1 Hour

1. tie-dye milk.

Sounds delicious, right? You’re not actually drinking it, but instead watching science magic happens when you combine dish soap with milk and food coloring. This is a very pretty experiment that draws the focus and mind into what’s happening on the plate, and all because of a little chemistry with everyday items. Well, food dye may not be an everyday item, but it might be after your kids get a hold of this!

So, what’s going on here, scientifically-speaking? Milk is made up of two major ingredients: water and fat. When you add a little dish soap, it bonds with the fat in the milk so strongly that it literally pushes the food coloring and water away from the cotton ball. On a microscopic level, the dish soap is wandering around the milk, which causes the colors to swirl and swirl.

Questions to ask beforehand:

• Before knowing what will happen to the food coloring, ask the kids what they think will happen when dish soap mixes with milk.
• Since the major catalyst is fat in the milk, what would happen if you used other types of milk: Skim milk, soy milk, coconut milk?

You’ll need:

• Round cake pan or plate with high edges
• Cotton ball (some tutorials show cotton swabs)
• Dish detergent
• Different colors of food dye (three or four should do)

Procedure/Instructions:

• Fill the pan halfway with milk.
• Drip one color of food dye in one section of the plate away from the center. Four to five drops works and later you can play around with more or less. Do the same for the rest of the colors around the plate.
• Soak the cotton ball in dish detergent, and when you’re ready for action, place the cotton ball into the center of the pan.
• Watch the colors racing around, creating a psychedelic tie-dye effect!
• You can add more cotton balls throughout the dish to see more action.
• If some food coloring hugs the wall of the plate, take a cotton swab dipped in dish detergent and place it into the food coloring. It will move away!

2. Saturn’s Glowing Rings

I don’t know about you, but I love everything about space. This experiment shows you how Saturn’s rings are made of rocks and ice chunks even though they look so smooth in pictures. You’ll also see why there are big gaps in the rings. Younger kids take delight in using a flashlight and sprinkling powder, while older kids can get more specific with questions about Saturn and how the rocks and ice stay in orbit.

• Do Saturn’s rings give off their own light?
• Why are some rocks and ice chunks more lit up than others?
• Compare the results of light sprinkles to thicker sprinkles.
• Strong flashlight
• Powder (flour, baby powder, etc) in a shaker
• Very dark room
• Darken a room and set the flashlight on the edge of a table or counter, pointing it at a blank wall. Lay the newspaper on the floor between the flashlight and the wall.
• Turn on the flashlight and notice where the light comes from the flashlight and where it hits the wall. You should only see the light from these two places and not from the space between them. This shows you that the light travels through the air without being seen until it hits the wall. The light represents the sun’s light.
• Now to see how Saturn’s rings glow: Hold the powder shaker and sprinkle some powder over the beam of light where you know the light is traveling. You’ll notice the powder lights up and sparkles in the beam of light. The powder shows in glowing clumps, just like in Saturn’s rings.

3. Breaking Down Colors

We all know that the fun, vibrant colors we see in our lives are created by mixing the basic red, yellow, and blue. In this experiment, you and your child will learn which colors make up those fun shades they have in their art supplies. This also teaches some basic chemistry and uses materials you already have at home. It can be done very simply and expanded to create a large-scale investigation if you love it.

• Which colors separate out first?
• Is the same order for each test?
• Which colors make up the original shade?
• Do the different types of color (pen, pencil, paint) separate in the same way or differently?
• Are some separated in a shorter space are the colors the same mixture?
• Coffee filters
• Color sources (markers, colored pencils, paint, etc.)
• A plain pencil
• To complete this experiment, cut the coffee filters into strips, mark one end with a line the same distance from the bottom on each strip.
• Color in each strip (between the bottom and line) with your colors, and write at the top what the color and source are (e.g., purple marker).
• Place each strip in a glass and help it to stand up by folding the top over a pencil (a chopstick, table knife, or any long narrow object will also work) so that it stands up in the glass.
• Fill the glass up to the top of your colored block, and wait. The water will move up the filter, and the colors will separate out as it goes.
• Remove the strip once the water gets near the top of the strip to stop the experiment. 

To make this a true experiment, we recommend testing multiple colors and using markers, colored pencils, and paint (as some starting examples). You could test the same colors from each type of art supply to investigate whether they all use the same mix of basic colors to create the same end product.

This post has a nice full description of the methods if you need more detail.

4. Water Xylophone

This simple experiment will teach your child about sound and pitch using glasses, water, and something to act as a mallet. Don’t let the simplicity deceive you, there are a lot of ways to experiment and learn through this process, and it also brings in an element of music that makes it interesting and engaging.

• Do you think more water makes the sound higher or lower in pitch?
• How do you think the shape or size of the glass will affect the sound?
• How should we arrange the glasses to play a simple song?
• Do you think this will work with a plastic cup, why or why not?
• Some glasses
• Something wood to act as a mallet (we recommend wood so you don’t break the glasses!)
• A great way to start is with glasses that are the same size, shape, and material, and filling them with different amounts of water.
• Have your child use the mallet to test how the amount of water affects the sound.
• From there, it’s a really simple extension to use different sized and shaped glasses (or any glass vessel like jars and bowls) to experiment with how the shape, size, and amount of water in the glass affect the tone. 

To take this one further and really bring in the musical component, you and your child could work out a simple song and create the right tones to play it. If you or your child are musical, you could get very elaborate and creative (try googling harry potter or star wars theme songs on glasses, there are so many options that I couldn’t even choose one)!

5. Ultimate Bottle Flipping

Ah, bottle flipping. The fad that kids can’t get enough of, but parents are well and truly over. The constant thud of semi-filled water bottles being tossed (and hopefully landing upright) is guaranteed to send parents around the twist!

If you can stand it for a bit longer though, there’s a lot of STEM knowledge to be gained in this bottle flipping experiment. As we know, the aim of bottle flipping is to flip a partially filled water bottle underhand and get it to land upright.

In this experiment, kids will learn the importance of observing a result multiple times before changing a variable (the amount of water in the bottle).

• How much water should you put in the bottle?
• What is the ideal amount of liquid to get the perfect flip?
• What should be the ideal amount of water?
• Was their prediction correct?
• Why do they think the amount of water affects the chances of landing the bottle?
• A plastic water bottle
• Measuring jug
• Paper to record results
• Get the kids to start by flipping their bottle with no water in it at all. Kidspot recommends flipping it 50 times for each step, but you could do less if you need to.
• Try it again with 50ml of water.
• Keep adding more water until the bottle is full.

If they’re keen, you could try other types or sizes of bottles, or even try different liquids to see if that affects the results!

6. Rainbow in a Jar

This simple science experiment is not only very visually appealing, but it’s also a great way to learn about the density of liquids. Warning though, this one could get messy so make sure kids are in some old clothes and you might want to take it outside! I like this experiment because you’ll probably have most of the materials in your kitchen already!

• Which liquids they think will be heaviest?
• Which ones will be lightest?
• Why do they think that?
• A glass jar
• Food coloring
• Various liquids like honey, corn syrup, dishwashing liquid, olive oil, rubbing alcohol and water.
• Use the food coloring to make all your liquids a different color. A dropper comes in handy here, but if you don’t have one you can manage without.
• Slowly add each liquid to the jar (pouring into the middle of the jar is best).
• Soon, you’ll have different layers of colored liquid forming your very own rainbow in a jar.

You might even get them to draw a diagram of what they think the jar will look like at the end. They can compare this with the experiment results to see if their prediction was correct.

It might also help to talk to your kids first about what density is and how materials are all made of different amounts of molecules. The more molecules a liquid has, the heavier it will be. Playdough to Plato demonstrates a great way of introducing this concept using marbles. 

7. Write Your Own Secret Messages! 

We love science experiments that are made up primarily of supplies that you likely already have in your home.

• Why do you think this will work?
• Which liquid do you think will make the best secret message?
• Why do people write secret messages?
• Juice (eg. Lemon)
• Lamp (or anything else that can be used as a heat source)
• In order to complete this experiment, you’ll need to gather all of your supplies along with a piece of paper, some q-tips, and a lamp or other item that you can use as a heat source.
• Next, you’ll mix your lemon juice with a slight amount of water. 
• Using your q-tip, use the mixture you’ve created to begin writing your message. 
• Allow it to dry. 
• Once dry, apply heat to it in order to get your message to appear.

Extend this project by attempting to write with a juice and water mixture, a milk and water mixture, or any other variation of the liquids we listed as necessary supplies!

8. Create Your Own Butterfly

Your little ones will love practicing their color mixing by creating their very own coffee filter butterflies. Hang them in the windows of your home to spread some cheer and to watch the sun flow through their beautiful wings! 

• What colors can mix together to make other colors?
• How do butterflies fly?
• What do you think will happen when we add water to the markers?
• Water spray bottle
• Allow your child to draw on the coffee filter to their heart’s content.
• Spray it with water and allow the colors to mix together.
• Allow it to dry thoroughly.
• Once dry, fold it like a fan and then clip it in the middle.

Ta-da, you’ve created a beautiful butterfly! 

9. Make A Duck Call

Give your family an excuse to head outdoors by allowing your children to craft their own duck calls. Test them out at a local pond and see if you can get the ducks to come closer to you for a healthy veggie snack! 

• Do you think ducks will be able to hear us with this?
• What other materials do you think could make this noise?
• How is what we have created similar to a duck’s beak?
• Plastic straw
• Push down on the straw to flatten one end and then cut the flattened end into a point.
• Flatten out your straw and then blow into it.
• Feel free to experiment with different amounts of flattening and different point shapes to see how you can adjust the sound.
• When finished, take your duck call into the wild to test it out.

10. Make Ivory Soap Boats

Did you ever carve items out of soap at camp when you were a child? Give your child the same opportunity. Soap can be carved using safe items, like plastic knives. 

• Why are we able to carve soap so easily?
• Do you think our boats float?
• Why do you think they float or sink?
• Carving tools (for kids)
• Allow your child to express their creative side by carving their boat out of soap. 
• Once they have finished carving it, allow them to test them out in the bathtub. . Extend their learning by discussing density with them–the soap floats because it is less dense than the water.

11. Make Your Own Quicksand 

As John Mullaney famously said, “I thought quicksand would be a much bigger problem in my adult life than it would have turned out.” For some reason, quicksand permeates children’s adventure stories – and their imaginations! 

• Where can we find quicksand in real life?
• How do you think quicksand works?
• What do you think we will need to make our own quicksand?
• Cornflower (one cup)
• Water (half cup)
• A container
• To make your quicksand, you’ll need to mix the cornflour and water. 
• Be sure to stir slowly in order to demonstrate – if you stir too quickly, it will become hard and you won’t be able to see it function the way it should!

12. Make Your Own Lava Lamp

We’ve tried this one in our classrooms, and trust us, our kids go wild year after year. Kids love making something that they can use as home decoration, and they love how easy it is to show new people – this is the experiment that lives on and on! 

• How do you think density is involved in this experiment?
• Why don’t the water and oil mix?
• Why can’t we shake our lava lamps?
• Clear Plastic Bottle
• Vegetable Oil
• Food Coloring
• Alka-Seltzer
• Pour water into the plastic bottle until it is approximately one quarter full. 
• Then pour vegetable oil in until the bottle is almost completely filled. 
• Allow some time for the oil and water to separate. 
• It is important that your children do not shake the bottle in this step. It will extend the experiment for no other reason than you waiting for the bubbles to dissipate. 
• Add as much food coloring as your child deems fit and then drop a piece of Alka-seltzer tablet into the bottle for the lava lamp fun to begin.

13. Guess the Smell

This one will take a little more prep work, but it’s a great touchstone for your children to begin discussing one of their five senses: the sense of smell! 

• What are examples of times we use our sense of smell?
• What other senses do we have?
• If you could only use one sense for the rest of your life, which one?
• Plastic Cups
• Smells (eg. coffee, cinnamon, vanilla, lemon juice)
• Place a variety of common smells in small plastic cups. We like to use coffee, cinnamon, vanilla, and lemon juice. 
• Pour these in and place tin foil securely over the top of the cup. 
• Poke small holes in the top of the foil. 
• Secure the foil with tape (on the sides, not over the holes). 
• Allow your children to guess the smells and record their findings on paper.

Home Science Experiments that take 1 to Several Hours

14. mangrove bioshield  .

Ecologists and conservationists are pushing for more regulations in building and saving mangrove forests around coastal areas. The reason is represented in this STEM activity. The trees act as a mangrove BioShield (bio = life, shield = protection), showing how natural obstacles can prevent critical damage from marine natural disasters such as tsunamis.

The mangrove BioShield can be for older elementary kids through to high school. Obviously, the younger they are, the more parent involvement. This experiment is done twice to show the effects of having and not having a BioShield. The first part uses little to no trees, and the second uses a forest of trees and rocks.

• What will happen in a tsunami if the village is without a BioShield? And the village with a BioShield?
• Would a BioShield help with hurricanes?
• Would you want to encourage people to save manatee forests if they are beneficial?
• Medium to large clear, plastic container
• Newspaper – wad into balls, then cover half of the bottom container – this help to keep the ground sturdy
• Mud – cover the newspaper and press it in to form a slope down to the empty side of the container. The top side should be flattened for the cardboard houses, then it slopes down into the empty half of the container.
• Cardboard houses (use the bottoms of milk cartons for the house and popsicle sticks for the roofs, place houses on the mud towards the top of the high slope
• Model trees or leafy stems from plants – Different amounts for activity 1 and activity 2
• Several small rocks
• Cardboard – long enough to fit across the container and tall enough to hold it from out of the water
• Water – enough to go halfway up the slope

A tsunami without the mangrove forest – insert only one or two trees down the slope. Place the cardboard piece into the water end of the container and move back and forth to create waves. Notice how easy it is for the water to destroy the village you’ve created.

Part 2: 

Repeat the process of constructing the village, but this time insert a lot of trees down the slope to where the water meets the mud. They need to be deeply rooted like mangroves, and I’ve found that aquarium plants work well for this reason. Place the rocks within the mangrove forest and in front of the trees. Add a little bit more water. Insert the cardboard again and move it back and forth to create waves.  

15. A Greater Crater

When you look at the night sky and see the moon, one of the first things you notice is its craters. The moon is completely covered in them, and some are so large we can see them from Earth. Meteorites often make the craters that we see when they hit the surface, but it makes us wonder why some craters are so much bigger than others.

This experiment will help you to investigate one of the main reasons why craters come in different sizes.

• What causes craters?
• How big do the meteorites have to be to make a crater?
• What is it about the meteorite that causes the size of the crater?
• Paper to record your results
• Flat floor surface for the experiment, large enough for the newspaper to cover
• Shallow metal pan at least 2 inches deep
• Flour to fill 2 inches of the pan
• ¼ cup hot chocolate powder
• Mesh strainer or flour sifter
• Large marble (and others of varying sizes if comparing results)
• Metric ruler
• Tongs or long tweezers
• Pour the flour into the pan until it reaches 2 inches. Place the pan on top of the newspaper on a level surface.
• Sift a layer of hot chocolate powder over the flour (this is so you can better see the rays and other features of the craters).
• You will be dropping your marble from three different heights, then comparing the sizes of the craters. Measure the diameter (side to side) of the marble and record this on your paper as Marble 1. Hypothesize how large the crater will be and write that next to the diameter of Marble 1.
• Stand next to your pan and hold the marble at knee height above the flour. Drop the marble (do not throw it, just let it fall from your fingers) into the flour and study the shape of the crater. Look for a rim around the crater or any rays coming from the edges.
• Measure across the widest part of your crater, from rim to rim and record on your data sheet as Marble 1 – Knee Height – Width or something similar. You can also draw a picture of your results.
• Very gently use the tongs or long tweezers to remove the marble without destroying the crater.
• Repeat this procedure from waist height, shoulder height, top of head height. Make sure you aim in different parts of the flour so you don’t land on top of another crater. Record all of your results as the different heights you’re using.
• Compare your results.
• You can try again with a different sized marble as “Marble 2” to compare those results with each height as done with Marble 1.

Perhaps now, you’ll look at the moon a little differently!

16. Rube Goldberg Chain Reaction Machine

We’ve all seen them, some pretty far-out there chain reaction machines to complete simple tasks, usually in movies. But they are real , and are becoming even more popular now that we’re all stuck at home for a while. This is a fun way to explore physics with stuff you have at home.

Ask your child to decide what the end goal is (e.g. get the ball into the cup), and ask them to think about creative ways to make it get there. Working together, you can start with small pieces of a circuit to find out how your ball reacts to the set-up, and grow it from there. You can even refer to this video for more ideas:

• What will happen when the ball bounces off of this wall?
• How will these dominoes change the speed of the ball?
• What can we use to make sure that the ball goes in the direction we want it to at this point?
• What should we put here to get the best bounce? 
• Paper towel
• Toilet paper tubes
• Fixed objects like walls or furniture
• Any other toys and materials that can be used to build your circuit

To make this a true experiment, it needs to include more than a one-off demonstration, and there are a lot of ways to accomplish this.

• Set up parallel courses and use different sized or weighted balls to go through the circuit.
• Set up one elaborate circuit and use different objects one at a time.
• Set up circuits in different ways to see how different set-ups affect your end goal.

Another experimental component is the process used to create a circuit that reaches your end goal ( like this video about getting the ball into the cup, but you could come up with lots of other endpoints!). Along the way, you and your child get a lot of time to learn about momentum, velocity, friction, energy transfer, and interference (e.g., the cat). 

17. Melting

This is a simple and fun experiment that can be set up in a short time and then fill-up your day with observations and new experiments. Using only things you already have at home, you can set-up an engaging experiment with your kids!

Ice melts at different rates depending on a variety of factors including temperature, pressure, and if there are impurities (think salt, sugar, dirt) in the ice or touching the ice. There is a lot of opportunities to get creative and do the experiment in multiple ways, keeping your kids engaged and developing their investigative, experimental, and critical thinking skills.

• Which ice melts the fastest, slowest, and if they have any guesses about why?
• What other ice-melting experiments they think would be fun: Using different temperature liquids? Using different amounts of ice? Different sized cups?
• Lots of ice
• Several matching cups (i.e., they are the same size, shape, and color)
• Measuring cups
• A variety of liquids for the test
• Paper for writing down observations
• Measure the same amount of ice and place it in each cup.
• M easure equal amounts of each liquid and place them in the cups: try to complete this part quickly so that the ice in each cup is in liquid for as close the same amount of time as possible.
• Set up your cups in a place that is easy for your child to watch and observe.
• Ask them to check in at regular intervals (every 15 minutes, every hour) and record or talk to you about their observations.

Other potential experimental examples:

• Using different liquids to test if they affect melting time;
• Using the same liquid and placing ice in different locations to test what conditions throughout your home affect melting;
• Test if different amounts of ice melt at different rates;
• Test if different kinds of cups change melting time.

There are endless possibilities for you to come up with new ways to complete these simple experiments. You get the idea. Explore more!

18. Breathing Leaves

Science experiments don’t get much more simple than this one!  It’s effective though and kids will enjoy watching their leaf ‘breathe’. Learning about plant science is often tricky because it can seem a bit abstract. This experiment allows kids to see the process of plants making oxygen right before their eyes!

A question to ask beforehand:

• What do you think will happen if we leave it for a few hours?
• A fresh leaf from a tree
• A bowl of water
• Pluck a fresh leaf from a tree and place it in a bowl of water.
• Use a rock to weigh it down and leave the experiment out in the sun.
• Have your kids predict what they think they will see when they come back in a few hours (they can write their prediction down or draw a diagram if that’s more their style).
• After a few hours, your kids will see lots of tiny little bubbles on the edge of the leaf and in the glass bowl of water (use a magnifying glass to get a closer look if you have one).

So, what’s happening here? Leaves take in carbon dioxide and convert it to oxygen during photosynthesis. The bubbles you can see are the leaf releasing the oxygen it’s created. You could explain to your kids how trees and plants make the oxygen we need to breathe. Kids Fun Science explains this experiment in more detail and suggests taking it further by leaving the plant for a longer period of time (do you see more or fewer bubbles?) or placing a leaf in a dark area to see what difference that makes!

19. How Does Sunscreen Work?

If there’s one thing I know, it’s that kids hate wearing sunscreen! Trying to get it on them is like wrestling a crocodile. Maybe if they knew how sunscreen worked they’d understand how important it is to wear it when they’re out in the sun (and be slightly more cooperative when we’re lathering it over their little faces). This is a simple experiment that shows kids the difference wearing sunscreen will make to their skin.

• What do they observe when they come back?
• Why do they think one side faded and the other not?
• A piece of colored cardboard (a dark color would be best)
• Your usual bottle of sunscreen
• Have your kids smear the sunscreen over one part of the cardboard and leave the other part clear.
• Kids can then predict what they think will happen when they return to the experiment after a few hours.
• Talk to them about how the sun’s UV radiation is absorbed by the sunscreen so it can’t get through to damage the cardboard.

You could even take it further by trying different kinds of sunscreen or leaving your cardboard out during different times of the day.

20. Make A Rubber Egg

Imagine a world in which eggs can be used like bouncy balls. Well, with a couple of home supplies and a little bit of science, you can live in that world. Your child will be dazzled as they remove eggshells from eggs while leaving the insides intact. 

• Is vinegar an acid or a base?
• Is there another substance that could do this?
• Simply leave the egg in the vinegar for a few hours and wait to see what happens. Because of the transformative nature of this experiment, it lends itself to science journaling. 
• Consider having your kiddos draw before and after pictures of the eggs in order to track their journeys. 

21. Flying Tea Bags

Nothing will get your kids’ attention faster than telling them that you are going to spend some time creating something that will fly. However, because this experiment will involve fire, please ensure that you select a time in which you will be able to provide ample adult supervision. 

• How do we stay safe with fire?
• How do we make sure we don’t damage the surface we are working on?
• Why do you think the tea bag will fly?
• Single Serving Tea Bags
• A Small Bowl
• A Non-Flammable Work Surface
• First, open the tea bags and unfold them. 
• Empty the leaves from the bag. 
• Stand the tea bags up on your surface and light the top of each bag on fire. 

As they begin to burn, they will float into the sky! 

22. Make Wax Paper Lanterns

Your children will love the chance to display their fantastic art skills by creating these paper lanterns. If you want to add a culture lesson, have your children research German’s St. Martin’s Day and learn about why children parade through the streets with lanterns. We promise there’s a good moral story involved here! 

• When could we use lanterns?
• What safety considerations do we need to use in this project?
• Why can we see the light through the wax paper?
• Popsicle Sticks
• To begin, tear a ten-inch piece of wax paper off of the roll and cut it in half. 
• After that, fold each piece in half. 
• Allow your child to color their image on top of the wax paper. (This is a great place for an impromptu lesson in color mixing). 
• Fold the wax paper and iron it (consider something in between the crayon mess and the iron you use on your clothes). 
• Finally, glue the craft sticks into squares, add the wax paper, and turn it into a cube.

Voila, you’ve created your own lantern!

23. Create an Insect Habitat

Alright, this one isn’t for the faint of heart. Draw up your courage and send your child into the backyard to collect all of the creepy crawlies they’d like to.

Now you have a home for them. Better yet, you can keep your child entertained for hours as they track the growth of their bug friends.

• What do bugs need to survive?
• What do bugs eat?
• What is the difference between a need and a want?
• Imagination
• Find something that you’re willing to sacrifice to the bugs in order to create a habitat for them – we recommend a shadowbox so that your child can see inside, but a cardboard box will do just fine as well. 
• Ensure that there is breathing room for the bugs. 
• Create a habitat with sticks, bark, small rocks, dried leaves, and whatever else you can find.
• If you’re willing to hang onto the habitat long enough, use it as an opportunity to talk about decomposition as the bugs begin to break down the twigs.

Long-Term Science Experiments at Home

24. crystal kingdom.

This is the oldest trick in the book, but it’s popular because it’s so effective, fun, and has great results. The only drawback to most crystal-growing recipes is that they take ages to grow, and to be quite honest this one is no exception. In fact, these crystals will take several days to grow but the end result is worth it. The reason is that this experiment involves growing a whole landscape of beautifully colored salt and bluing crystals. Here’s a video for visual reference: 

A few things to keep in mind: Allow for plenty of air circulation, preferably inside rather than outside. Ammonia is not necessary but does help in the process.

• What will happen when you add ammonia?
• Why does more salt and less liquid create faster crystallization?
• What part does the bluing solution have in crystal growing?

(Answers can be found here )

• Two bottles of bluing solution
• Large tray/cookie sheets with sides
• Measuring cup
• Liquid watercolors
• Eye droppers
• Cut sponges into large pieces. Spread them out on the tray.
• Measure out 1 cup of each of salt, water, and bluing and then gently mix together.
• Evenly coat or sprinkle the mix over the sponges.
• Add 1 cup of ammonia to the sponges.
• Coat an extra 1 cup of salt on to the sponges.
• By now you’ll see some crystals growing . Sprinkle the magic mix again: 1 cup each of salt, water, and bluing. You can pour the ingredients onto the tray instead of on top of the crystals to keep them from breaking. Don’t worry, more will grow!
• Take an eyedropper, and drop a tablespoon of each liquid watercolor (undiluted) in different patterns over the sponges and crystals.
• Take note of your garden and what the crystal formations look like. You can make a sketch in your notebook as a before and after. Ask questions and observe!
• Observe how the crystals are bigger than before, and notice the colors aren’t as vibrant. Compare the differences in shapes, sizes, and colors.
• If you want more crystals to grow, add a little more water, bluing, and salt.

25. Blow up a Balloon with Yeast

We are surrounded by science in action, but sometimes it is really difficult to see what is happening, especially when it is on a small-scale. When we make bread, yeast ‘eats’ the sugars in the food and creates CO2, giving bread its airy texture. This experiment lets you both visualize what happens when yeast consumes sugar and is a great set-up for an experiment that can be observed throughout the day.

Depending on your supplies and time, you could start with a demonstration and use that to think of other tests, or you could set up several parallel tests at the same time.

• How quickly does the balloon filled with air?
• When does it stop filling (at some point the yeast will run out of food and will stop making gas)?
• Does the starting temperature affect the experiment?
• Does the balloon fill faster in different places in your home (try especially for different air-temperatures, you could include an outside location)?
• Some balloons
• Blow up the balloon a few times before starting so that it’s loosened up a bit.
• Fill the bottle with about 1 inch of warm water (heat is required to activate the yeast, but you could experiment with different temperatures), add the yeast and swirl to dissolve.
• Add the sugar and swirl more.
• Place the balloon over the opening to the bottle and wait. You should expect to see the balloon begin to inflate after around 20 minutes.
• Continue checking and observing how much the balloon inflates throughout the day.

More example experimental setups include:

• Do different temperatures – either with the water you start with or the air the yeast lives in – affect how quickly the balloon blows-up?
• Does using 2x the yeast result in a balloon that is 2x bigger, or blows-up 2x faster?
• Do different types of sugar (e.g., white sugar, honey, syrup, flour) affect how quickly the balloon blows up or how big it gets?

A sk your child to think of new experiments (you could prompt with some of the examples above, or ideas from this post ). 

26. Seed Germination

A really simple but fun multi-day experiment is germinating seeds under different conditions. This means finding some quick-sprouting seeds such as beans and putting them in different conditions to see how that affects germination (sprouting leaves and roots) and growth.

I love using seed experiments because they are inexpensive, simple, and leave a ton of room for creating your own unique experiment.

• Which seed will sprout fastest?
• Seeds (Beans, radishes, squashes, and many flowers sprout quickly from large seeds, making them good choices.)
• Small pots or paper cups
• Potting soil
• Cloth or paper towel
• Somewhere with good light
• To get started, you’ll need some seeds – feel free to choose something you already have, if you’re a gardener you might have some seeds ready for the coming season and could spare a few – or find something online or at your local nursery.
• Use small pots or paper cups and fill each with your growth material (we recommend a minimum of 3 for a useful comparison).
• Fill one with potting soil, one with sand, and one with a cloth or paper towel.
• Place them somewhere with good light, and add water.
• Ask your child to predict which seed will sprout fastest, and make observations every day. If possible, make them around the same time each day.
• Once you see growth, you can ask your child what they think caused any differences, and you can use that as a jumping-off point for more experiments

Additionally, you could:

• Use one type of seed and different types of growth media: soil, paper towel, gravel, sand, water, etc.
• You could use different seeds (beans, flowers, grass, herbs) and grow them under the same conditions (soil, water, sun exposure) to see how different plants grow differently.
• You could see how different light conditions (by a window, in the basement, in a bright room away from a window, etc.) affect germination.

You could also extend each experiment by simply continuing to grow each seed to learn whether the different germination time affects long-term growth (you may want to re-pot everything in the soil for this to be effective, depending on the specifics of your initial experiment).

27. Colored Celery

It’s hard to imagine plants having little capillaries inside them that transport water and nutrients, but this experiment shows that in action. It’s easy to set up, but you’ll have to wait at least a day to see some results. Your kids will be able to see how transpiration takes place and plants absorb water from the soil all the way up into their leaves.

• A few stalks of celery (celery works best for this because it’s a bit more visible, but you could also use flower stems)
• Different food coloring
• Place each stalk in a cup of colored water and make your predictions about what will happen.
• After a day or so you’ll see the celery leaves becoming the color of the water they’re standing in.
• Have your kids describe their observations (they can write down what they see or draw it if they prefer).
• If you look at the base of the stem you’ll also see tiny little holes that the colored water is traveling through.

When you’re done with the experiment, make sure you snap the celery and look inside – you should be able to see the capillaries in action. For more ideas, Little Bins for Little Hands has got some great hints and tips for this experiment.

28. Moldy Bread

This experiment is an oldie, but a goodie! Kids love looking at disgusting things and this one will certainly come up with the goods. Not only will kids learn about how mold grows, but they might also take on some lessons about the importance of washing their hands!

You might want to check out the results of this experiment at Science Alert before you start to see if your stomach is up to it.

• A few slices of bread
• Some ziplock bags
• Sticky little hands. 
• Get a few slices of bread and lay them out on your kitchen bench.
• Have your kids touch one piece of bread with dirty, unwashed hands.
• They can wash their hands with soap and water and touch another slice, then do the same using hand sanitizer.
• Leave one piece of bread untouched.
• Place them all in clear, labeled ziplock bags and predict which one will grow the most mold.
• Leave your bread slices for at least a week (it may take a bit longer, depending on the conditions where you live) and get the kids to record their observations.

You can also try wiping your bread slices on other surfaces to see what moldy results you get (their laptop or tablet is a great place to start)!

29. Sprouting Beans

Give your household a real survivalist feel by beginning an indoor garden. We recommend planting your beans in a clear cup so that your children can be privy to all of the processes during the plant’s journey.

• How does a plant grow?
• What does germination mean?
• What is in season to grow in our area now?
• Unprocessed Beans
• If you’d like your child to see every step of the process, consider placing the beans inside of a damp paper towel inside of a ziplock. 
• You can wait, see the germinated seed together, and then plant it inside of a small cup.
• Once inside the cup, watch it grow.

Extend your work by planting various beans and altering the growth conditions in order see what makes your beans grow best! 

30. Begin Composting

Begin your “go green” resolutions by teaching your child the value of composting! Best of all, once the science experiment is done, your family will have a recycling process that will last your entire lifetimes. 

• Why is composting important?
• How else can our household go green?
• Why do we need a foundation layer for compost?
• Compost Bin
• Organic Material
• First, create a compost bin. You can purchase one or build one out of wood. 
• To begin your composting, you’ll need even amounts of brown materials (think shredded paper, dryer lint, etc.) and green materials (think fruit and vegetable waste, lawn clippings, etc.). 
• If you’re really feeling fancy, throw some earthworms in there.

For days to come, your family will be able to discuss what can and cannot be broken down by the decomposers inside of the compost bin. Never-ending science! 

31. Turn Grapes Into Raisins

Your kids may or may not eat raising – but we can guarantee you, they’ve likely never considered the option of creating their own! 

• What other snacks can we make with science?
• Should we ever eat our experiments?
• How does this work?
• For this experiment, you’ll need grapes. (Really, that’s it!) 

Leave your grapes somewhere where they will not be disturbed and use this as an opportunity for your children to journal the changes in the grapes from day to day. Believe it or not, this type of sequential journaling is a valuable literacy skill! 

32. DIY Science Experiment

The best science experiment your child can engage in is the one they create themselves! Begin brainstorming a list of questions and let the world be their oyster as they plan and carry out their own experiments. Some of our favorite brainstorming questions, from Scholastic’s Science-Fair Project Guide, are listed below:

• What is the effect of toothpaste brand on teeth-cleaning power?
• What brand of trash bag can withstand the most weight before ripping?
• How does the type of material affect how long a shirt takes to dry?

20 Second Grade Science Experiments That Build Essential Skills

Looking for fun and hands-on ways to teach your students about science concepts? In this post, I’ll share twenty 2nd grade science experiments that will get your students excited AND help them build essential critical thinking skills.

Second Grade Science Experiments

In 2nd grade, students are building a lot of content knowledge in science. They are also developing critical thinking and problem solving skills that will set them up for success in future grades. One of the best ways to build these crucial skills is through experiments.

The twenty second grade science experiments in this post are tried and true activities to teach science content and help students develop critical thinking skills.

Pollination STEM Lab

Pollination is an important topic that we cover in 2nd grade during our Plants, Animals, and Life Cycles unit. This pollination lab helps students visualize the process of pollination in a hands-on way.

This easy animal seed dispersal activity is a great opportunity for students to design and build models and simulate how animals help plants grow. It’s the perfect activity for demonstrating plant and animal interdependence.

In this lab, students will use a variety of materials to create a model animal. Then, they will test out how seeds stick to their model animal. Learn more about animal seed dispersal here: Animal Attachment Seed Dispersal STEM Activity

Map a Mountain Topographic Map Activity

Add math and map skills to your science activities with this topographic map landforms lab. In this 3D topographic map activity, students will use clay to make a 3D model, then section it with dental floss to make a topographic map. 

Students will begin by making a simple model of a mountain out of clay. Then, they will use dental floss to section their model into equal slices. Check out how to do this activity with your class here: Topographic Map Landform Activity for Kids

Exploding Seed Pod Experiment

In second grade, we take time in science to study a variety of ways that seed dispersal happens. One way plants disperse their seeds is through an adaptation called exploding seed pods.

In this activity, students are challenged to build a model of an exploding seed pod using balloons and seeds. Learn more about how your students can make exploding seed pods here: Seed Dispersal Activity: Build an Exploding Seed Pod

Plant Adaptation Models

Plants and animals that live in water have special adaptations that allow them to survive. Help students understand plant adaptations by creating simple models with everyday craft supplies.

In this 2nd grade science experiment, students will design, make, and test simple models of water plant adaptations. It’s a great activity for introducing or practicing with engineering and design practices and concepts. Check out how to do this activity with your class here: Plant STEM Activities for Kids: Making Models of Adaptations

Second Grade Science Experiments for Teaching Properties of Matter

Ice cream in a bag experiment.

The ice cream in a bag lab is an excellent 2 nd grade science experiment to introduce or reinforce the states of matter.

In this lab, students investigate the effect of temperature on matter as they observe a liquid mixture turn into a solid.

This experiment is always a favorite for my 2 nd graders because they get to learn about the science behind one of their favorite treats. Read more about how this lab is done here: Ice Cream in a Bag Lab

Pop Rocks Lab

In this high-engagement 2 nd grade science experiment, students will explore carbonation using Pop Rocks candy and soda.

Students will test the solubility of Sharpie pen ink in water, vinegar, and rubbing alcohol. Then they will observe and describe the results in their test. Learn more about how to conduct this 2nd grade science experiment with your class here: Sharpie Solubility Experiment for Kids

Chlorophyll Paintings

Did you know you can make art with chlorophyll? Chlorophyll paintings are a fun and creative way to integrate art and science as students learn about plants, the process of photosynthesis, and how a plant makes its own food.

To complete this activity, you’ll just need white paper, a metal spoon, and some leaves. Check out how we did chlorophyll paintings in my classroom here: Chlorophyll Paintings: Incorporating Art in Science

Cookie Dunk Lab

Get students engaged and learning by using milk and cookies in your 2nd grade science experiments! In this fun and simple science experiment, students explore buoyancy as they learn and practice the steps of the scientific method.

Students will observe and record the properties of various mini cookies. Then, they explore whether each cookie sinks or floats. Read more here: Milk & Cookies and the Scientific Method

Properties of Matter Cracker Lab

In second grade, students learn that matter has observable, physical properties. This 2 nd grade science experiment reinforces this concept by allowing students use their senses to observe, describe, and taste properties of matter.

Students look at, feel, and taste different types of crackers in order to describe their properties. Click the link to read more about the cracker lab: Properties of Matter Cracker Lab

Blubber Glove Experiment

Learning about adaptations is a key component to second grade science lessons about habitats and ecosystems. The blubber experiment demonstrates how arctic animals stay warm in icy water.

Blubber is a thick layer of fat just under the skin of all marine mammals. It is an important and interesting adaptation that allows these animals to survive in cold water.

This 2nd grade science experiment recreates the layer of fat that keeps an animal warm. During this hands-on activity, students will compare the cold they can feel with and without wearing a “blubber glove”. Learn more about how you can make a blubber glove here: Arctic Animal Adaptations: Blubber Science Experiment for Kids

Cheese Powder Pollination Activity

Pollination is an important process in the life cycle of plants, and it can be very easy and fun to demonstrate. In this 2nd grade science experiment, students will use cheese powder from a box of macaroni and cheese to develop a simple model that mimics the function of an insect pollinating flowers.

There’s only a few simple materials needed for this experiment, and all of them can be found at the dollar store. Check out how to do this pollination experiment with your students here: Cheese Powder Pollination Activity for Kids

Flexibility Lab

Flexibility is one of the key observable properties of matter that we learn about in second grade. In this fun and simple 2 nd grade science experiment, students will test and record the flexibility of several objects.

Giving students the opportunity to plan and conduct simple investigations is crucial to promote learning in 2 nd grade. This flexibility experiment is a great way to give students this experience. Learn more about the flexibility lab here: Exploring Flexibility Lab

Parts of a Seed Lab

Learning about plant life cycles is a huge part of second grade science. Give your students an opportunity to familiarize themselves with the parts of a seed in a hands-on way with a lab activity.

Have your students dissect and examine the parts and functions of a seed using lima beans. Then, have students identify and label the seed parts they saw first-hand. Check out how to do this easy seed lab with your class here: Easy Seed Science Experiments

Butterfly Life Cycle Labs

Raising butterflies and learning about their life cycles is always a highlight in the second grade school year. Enrich your butterfly life cycle lessons by giving students the opportunity to learn about, observe, and write about the process of caterpillars transforming into butterflies. Learn more here: Butterfly Life Cycle Activities & Free Printables

Lighthouse Water Erosion Experiment

The Save the Lighthouse Lab is a fun and exciting way for students to learn more about slow earth changes and erosion. This activity is more of a simulation to demonstrate how ocean waves can cause erosion and affect the coastline.

Students will use sand, water, and a paper lighthouse template to create a miniature coastline. Then, they will simulate ocean waves and observe what happens to the lighthouse. Check out more on the lighthouse lab here: Water Erosion Science Experiment: Save the Lighthouse!

Landslide Lab

Have you ever thought about how people can protect a town from a landslide? This landslide experiment allows students to explore how people can reduce the impact of landslides.

In this lab, students will complete a simulation of a landslide to design and test ways to help protect towns. It’s an excellent opportunity for students to practice problem solving skills with real-life implications. Learn more here: Landslide Science Experiment to Teach Fast Earth Changes

Gill Demonstration

When I teach my Habitats & Ecosystems science unit, we take time to learn about animal adaptations. In this lab, students explore a well-known fish adaptation: gills. 

This 2nd grade science experiment helps students to visualize the process of gills working in a fish’s body. It is basically a simulation that represents a simplified version of gills allowing a fish to breathe underwater. Read more about how to do this simulation with your class here: How Do Fish Breathe Underwater? Ocean Animal Adaptations Activity

Plant Needs Experiment – Can Plants Grow in the Dark?

Students will get the opportunity to explore why plants need sunlight in this 2nd grade science experiment.

In this lab, students will make observations on two plants over time. One plant will be left in the sunlight, while the other will be left in the dark. Learn more about how to do this experiment in your classroom here: Plant Needs Experiment: Can Plants Grow in the Dark?

Science experiments should allow students ample opportunity to practice critical thinking and problem solving skills. I hope these 2nd grade science experiments help your students have fun while learning key science content and skills! You can find all of these labs with ready-to-use lesson plans, student workbooks, lesson videos and assessments in individual units or in money-saving bundles.
