Updated
Ignite your child’s curiosity with 65 fun-filled science experiments perfect for home!

Is your kid bored at the weekends or while on school vacation? Are they couch potato-ing in front of the TV again? I know a brilliant way to keep your child entertained and engage their brain: science experiments.

Whether your child is intrigued by the thought of Imploding Cans or a Lemon Volcano, I’ve put together a list of 65 dazzling science experiments for kids! No need for a fancy science lab — you can do these all from the comfort of your home.

I’ll let you know exactly how to carry out each experiment. Gone are the days when there was nothing to do. Now you have 65 theories to test out!


Easy Science Experiments Kids Will Enjoy

From making a cloud in a bottle to homemade bouncy balls, here are 65 easy science projects for kids to try. Plus, most use household items, making this a cheap way to pass the time.

1. Cloud in a Bottle

Tightly secure the lid on an empty plastic water bottle. Twist the bottom of the water bottle as tightly as possible. This will compress the air and push all the molecules inside together.

When you open the water bottle, the molecules expand, releasing the pressure and creating an instant cloud.

2. Floating Fish

Learn about solubility and density with this fun experiment. On the bottom of a glass plate, draw the outline of a fish with a dry-erase marker.

After a couple of minutes, slowly pour tap water into the corner of the dish until it covers the plate. The water will move towards the fish drawing, surrounding it. Tilt the plate from side to side and watch as the fish drawing starts to float!

3. Lava Lamp

Learn about density and make a lava lamp at home. Add two inches of baking soda to the bottom of a jar, then fill the rest with vegetable oil until full. These two ingredients won’t mix.

Combine ¼ cup of vinegar with a bit of food coloring in a separate cup. Mix together before pouring the solution into the jar with oil and baking soda.

Turn off the lights and shine a flashlight on your lava lamp!

4. Foamy Fountain (Elephant’s Toothpaste)

In this experiment, kids will make foam with a few household ingredients. In scientific terms, this is called an Exothermic Reaction.

Pour ¾ cup of hydrogen peroxide into a bottle. Add 10 drops of food coloring and one tablespoon of dish soap. Swirl it around to mix.

Combine three tablespoons of warm water and one tablespoon of dry yeast in a separate cup. Mix for 30 seconds.

Use a funnel to pour the yeast-water combination into the bottle and watch it fantastically foam!

Warning

Don’t touch the foam. We know it’s tempting, but it contains peroxide, which can irritate your skin and eyes.

5. Magic Milk

Pour whole milk into a shallow pie dish with a flat surface. Add a few drops of food coloring to different parts of the dish. You can use tons of different colors!

In a separate bowl, pour some dish soap. Dip a cotton swab into the dish soap and gently touch the surface of the milk with the swab.

The soap will lower the surface tension of the milk, and the colors will burst and swim around.

6. Egg in a Bottle

Did you know you can fit an egg in a bottle without breaking it? Firstly, boil and peel your egg. Then grab a glass bottle (no plastic!) and ensure that the opening is smaller than the diameter of the egg.

With an adult’s help, light three matches and drop them into the bottle. Place the egg at the bottle’s opening with the wide end pointing up. The egg will slowly squeeze into the bottle as the fire goes out!

7. Floating Ping Pong Ball

Levitate a ping pong ball with Bernoulli’s Principle! Make a paper funnel using thick card. With a grown-up’s help, cut a small hole in the bottom of the funnel.

Insert a straw into the bottom of the funnel and secure it in place with putty or tape.

Add a ping pong ball (or DIY foil ball) into the funnel and put the long end of the straw in your mouth. Blow into the straw and watch the ball levitate because of the high speed and low-pressure air.

8. Imploding Cans

Imploding Cans

Fill up a few empty soda cans with a bit of water. Then, fill up a large bowl with ice cubes and water.

Heat a flat frying pan on the stove and carefully stand your cans on the frying pan until they are hot. Using tongs, transfer the hot cans one at a time into the ice water.

When the cans drastically change temperature, they implode on themselves and crush inwards.

Warning

This is one for parents to do and kids to watch. It’s not safe for kids to do on their own.

9. Eggs and Toothpaste

Learn about the power of toothpaste in this shocking science project for kids. Fill up four glasses, two with soda and two with lemon juice. Then cover two eggs in toothpaste and pop one into a soda glass and another into the lemon juice glass.

Next, place two more eggs into the remaining glasses. This time, they’re not covered in toothpaste. Leave all the eggs in the glasses for 12 hours.

Once the time is up, remove the eggs, rinse under cool water, and pat dry. You’ll notice that the eggs covered in toothpaste feel and look different than those without. This emphasizes the significance and protective abilities of toothpaste.

10. Black Pepper Trick

Teach kids about surface tension and the power of soap in this fun and easy experiment. Pour a thin layer of water onto a plate. Pour a bit of ground pepper all over the water’s surface.

Then pour a tiny amount of dish soap onto your finger. Dip your finger into the water, and you’ll notice the pepper quickly zoom away from your finger.

Need something for your science fair project? People will love watching this one in action!

11. Ice Cream in a Bag

Have fun and try something yum! Pour four ounces of milk and cream, ¼ teaspoon of vanilla, two tablespoons of sugar, two teaspoons of vanilla, and food coloring (optional) into a zip-bag and ensure it’s securely closed.

Place the bag into a larger zip-bag and fill it with ice and a small handful of salt to surround the smaller bag. Zip it shut and hold either side while shaking back and forward for about five to eight minutes.

Yes, your arms will be tired. But in the end, you’ll have ice cream! Open the large bag and remove the smaller bag. Rinse off salt from the bag and open it up. It’s ice cream time!

12. Magic Melting Skittles

Grab a plate and line up Skittles around the edge of the bowl. Pour a little bit of boiling water into the plate to surround the bottom. Watch as the colors from the Skittles slowly melt off and swirl together on the plate.

This experiment has endless possibilities. Try it with different colors and shapes on the plate!

13. Bouncy Egg

Turn a raw egg into a bouncy egg! Simply place the raw egg (uncracked) into a glass. Cover it completely with distilled white vinegar and leave for 24 hours. After 24 hours, you can gently scrape off the eggshell, and you’re left with a squishy, bouncy egg.

14. Grow an Avocado Tree

Wash an avocado pit and insert four toothpicks halfway up the side, on all sides. Suspend the pit over a jar and fill the container with enough water to submerge the lower third of the seed. Make sure the broad side of the pit is facing down.

Keep the jar in a warm place out of direct sunlight and change the water every few days. After a few weeks, roots and sprouts should start appearing.

When the sprouts are about six inches, cut it back three inches. This will encourage more growth. When the stem has grown back again, plant the avocado pit in a 10-inch pot with soil, and voila! Your avocado tree will grow.

15. Make Slime

This exciting experiment will provide days of fun! Mix together ¼ of water and ¼ cup of white school glue in a bowl. Add a few drops of food coloring.

In a separate bowl, combine ½ tablespoon of Borax and another ½ cup of water. Stir to combine. Add the solution to the glue mixture, and enjoy playing with the slime!

16. DIY Rock Candy

On the stove, combine a 1:3 ratio of water and sugar. Bring it to the boil.

Let it cool for 10 minutes before transferring to a large glass or jar. If you want colorful rock candy, add food coloring to the solution and stir.

Pour half a cup of sugar onto a plate. Dampen a wooden skewer in water and roll it around in the sugar. Then place the skewer into the glass jar and secure it in place with a clothespin so it stays in the middle of the jar.

After five days, your rock candy will have formed. Use a skewer to break the piece of rock candy out of the water. Place it inside an empty jar to dry, and yum! You have your own rock candy.

Get Help

Ask for an adult’s help for this one since you’ll be using high heat.

17. Baking Soda and Vinegar Balloon

Baking soda and vinegar can blow up a balloon without any help from your lungs. Using a funnel, pour about ¼ cup of vinegar into a bottle (with an opening small enough to stretch the mouth of a balloon over).

Put the mouth of the balloon over the funnel and add one tablespoon of baking soda to the balloon. Stretch the balloon over the bottle’s mouth and empty the baking soda into the bottle.

Watch as the balloon fills up with air. More technically, it’s carbon dioxide because that’s what happens when you combine baking soda and vinegar.

18. Frozen Bubbles

Blowing bubbles can be even more fun when the temperatures are below freezing. The bubble solution can freeze on the spot! You can do this with a bubble solution and a bubble wand — wave it around to produce bubbles.

The bubbles will either freeze mid-air, once they fall to the ground, or even while they are still attached to the wand.

Another option is to pour the bubble solution onto a plate or shallow bowl. Use a straw to blow a bubble into the solution. The bubble will slowly freeze, forming ice crystals.

You can pop the bubble and notice how it shatters and crumples rather than disappears like a normal bubble.

19. DIY Phone Speaker

When you don’t have your own Bluetooth speaker, you can easily make one with paper cups and toilet roll tubes. On the toilet roll tube, cut out an opening on one side that will fit the bottom of your phone.

On the paper cups, cut out a small opening to fit the end of the toilet roll tube through. Connect the pieces together, choose your favorite song, and insert your phone speaker into the toilet roll tube.

The system will naturally amplify the sound from the phone! Dancy party time.

20. Invisible Ink

Reveal hidden messages with this science project for kids. Pour ⅓ cup of baking soda and ⅓ cup of water into a bowl. Mix together before adding a cotton swab into the solution and writing a secret message onto a card.

Pour 100 percent grape juice into a cup. Dip in a paintbrush and paint over the secret message to reveal it. This is a great way to teach about acids and bases.

21. Milk Bottle Xylophone

Make music with items you already have in the house. Line up six glass bottles and pour a different amount of water into each jar.

Make music by tapping a metal spoon on each jar. Notice how the amount of liquid in each jar changes the sound waves and vibrations, resulting in a higher and lower pitch.

22. Dancing Raisins

Fill a clear glass with clear soda and fill another glass with water. Place a few raisins in each glass and notice how the raisins dance in the soda liquid but not in water. This is because the gas bubbles carry the raisins up, and when the bubbles pop, the raisins sink again.

23. Exploding Lunch Bag

This chemistry test is a great way to add excitement to a dull Saturday morning!

Fill a zippable lunch bag with ¼ cup of warm water. Add ½ cup of distilled white vinegar. Zip the bag shut.

Place a piece of tissue or paper towel down and pour three teaspoons of baking soda onto the middle. Fold the tissue over itself.

It’s time to be speedy! Open the zippable bag enough to add the baking soda tissue.

Once you’ve added it, quickly shut the bag, put it on the ground and step back. The bag will begin to expand and eventually… BOOM!

Top Tip

Do this experiment outside. You don’t want a mess on your living room floor!

24. Lemon Volcano

Let’s make citrus volcanos! This is a great one for science fair projects.

Cut the top and bottom off a lemon and carve out the insides. Add food coloring to the inside and fill the lemon with baking soda. Mix with a knife and watch as the baking soda starts to fizz out.

You can also try this with different citrus fruits, like an orange or grapefruit. Make it with different colors to have a rainbow volcano collection.

25. Walking Water Rainbow

Place seven identical jars or glasses in a row or a circle. Fill every second jar ¾ full with water, so jars #1, #3, #5, and #7 have water.

Then add a big squirt of red food coloring to jars #1 and #7, yellow to jar #3, and blue to jar #5. Jar #2, #4, and #6 will remain empty.

Fold six paper towels in half (hot-dog style), then in half again, making long, thin pieces of paper towels. Fold each paper towel in half (hamburger-style), so they make a tent shape.

Then place one end of the paper towel in the first cup and the other half in the second cup. Repeat with each paper towel.

Each cup should have two paper towel ends inside unless your cups are in a row. In that case, the first and last cups will only have one paper towel end inside.

After a couple of hours, the paper towels will have soaked up the food coloring using a capillary action. The colors mix together to create the shades of the rainbow: red, orange, yellow, green, blue, indigo, and purple.

26. Rising Water

Fill a shallow bowl with enough water to cover the bottom. You can add food coloring for more fun!

Place a tealight candle in the middle of the water and light it. Quickly place an empty glass over the candle.

The candle will gently burn out while water rises into the glass. This is a great way to teach Charles’s Law, which conveys how when temperature decreases, the volume does, too, allowing water to rise and fill the empty space.

Warning

Get an adult to help with the Rising Water experiment, since it involves fire.

27. Bend Water

Run your kitchen or bathroom tap with a very thin stream of water. Blow up a balloon and create static by rubbing it against a towel or your hair. Hold the balloon close to the water and watch as the water bends towards the balloon.

28. Citrus Pops Balloons

Citrus Pops Balloons

Limonene, a component in citrus, has the ability to dissolve rubber, which is a component of balloons (1). Therefore, when you squirt citrus onto a balloon, it pops!

Blow up a few balloons. Peel an orange, ensuring you have large pieces of the peel to hold.

Hold the peel a few inches from the balloon, with the rind side facing the rubber. Quickly squeeze the peel so the liquid squirts onto the balloon, and it should pop!

Something To Note

Not all balloons will pop through this experiment. If the balloons are made from natural rubber, they will most likely pop easily. But if the rubber is vulcanized, it’s more durable and harder to dissolve.

29. DIY Compass

Never get lost again! To make a compass, stroke a strong magnet down one length of a sewing needle 50 times. Then flip the magnet and the needle, and repeat on the other side.

Cut a cork so it’s about 1.5 centimeters thick. Push the needle through the cork — you may need to use pliers, so ask a parent for help.

Next, fill a bowl with a few inches of water. Place the cork into the water, and it should point North.

30. Sink or Float

Sink or Float
Fill up a basin, bath, or sink with water. Grab a few household items you don’t mind getting wet, and put them into the water.

Take note of which ones sink and which ones float. Can you determine why?

31. Optical Illusions

Optical Illusions

Optical illusions are an incredible way to confuse your brain using your eyes. Why not get a book of optical illusions for your kids to flick through all summer? This will keep them entertained — and amazed.

32. Pumpkin Volcano

Cut a hole in the top of a pumpkin and clean out the insides. Pour ¼ cup of baking soda into the pumpkin with a squirt of dish soap and watch the pumpkin start to foam from the top!

33. Create a Marshmallow Catapult

Stack up six popsicle sticks and tie them together with a rubber band on either end. Then tie a wooden spoon and another popsicle stick together at the bottom end of the spoon. Push the large stack of popsicle sticks between the spoon and the second stick until it’s halfway down.

Secure it together by making an “X” with a rubber band where the two sticks meet. Then put a mini marshmallow on the spoon and pull it back slightly.

The marshmallow should fly through the air! If not, adjust your mechanism until it can catapult the marshmallows.

34. Make Ginormous Bubbles

Make Ginormous Bubbles

Make the biggest bubbles your eyes have ever seen! Mix together six cups of distilled or purified water with ½ cup of cornstarch.

Add one tablespoon of baking powder, one tablespoon of glycerine, and ½ cup of dish soap. I recommend Blue Dawn dish soap.

Use it with a giant bubble wand. If you need to make your own giant bubble wand, do this beforehand so you can use the bubbles immediately.

35. Magnet Experiment

Fill a glass with water and add a few tablespoons of magnetic fine iron filings. Run magnets up and down the side of the glass and watch the iron fillings move around.

36. Paper Bridge

All you need for this are pieces of paper, two plastic cups, and a bunch of pennies. Create different types of bridges by trying out different designs with the paper. Add one penny at a time to the bridges to discover the strongest bridge design.

37. Shine Up Pennies

Shine Up Pennies

Discover how to clean copper pennies using household items. Fill different cups with different liquids, including white vinegar, soapy water, ketchup, and soda. You can fill up the other cups with any liquid you please!

Put a penny in each cup and wait 10 minutes. Then rinse the pennies with water and rub with a paper towel. Which liquid cleans the pennies best?

38. Egg Drop Challenge

The aim here is to drop the egg into the glass of water. So fill a glass full of water (make sure it’s big enough for the egg) and place a piece of cardboard or a small tray on top of the glass. Then place a toilet paper tube on top of the tray before balancing the egg horizontally on the tube.

When you’re ready, strike the tray or cardboard away with your hand, making sure to send it flying away without knocking over the water. The egg will hang in the air for a split second before dropping into the water.

39. Green Pennies

Above, I taught you how to polish pennies. Did you know you can turn pennies green using a very similar method?

Fill up two bowls with ¼ cup of vinegar and one teaspoon of salt. Mix well. Add a few pennies to each bowl.

After 10 minutes, remove the pennies from one bowl, rinse them, and lay them flat to dry on a paper towel.

Take the other pennies from the second bowl and place them onto the paper towel. Don’t rinse! Wait and see what happens.

The pennies that you rinsed will be polished. But the pennies you didn’t rinse will be green. This is called a patina — a layer caused by the weathering chemical process you just carried out.

40. Homemade Butter

Homemade Butter

Pour heavy cream into a jar and put the lid on tight. And start shaking! This is a great one for siblings so they can take turns because it can take up to half an hour for the cream to turn to butter!

As the cream solidifies, it separates from the buttermilk. When you remove the lid, pour the buttermilk away; underneath, you’ll have butter. Spread it on your toast, and enjoy!

41. Neon Flowers

Fill up a few glasses with water and five drops of food coloring. Mix well before adding white daisies or carnations to each glass. The next day, your flowers should be bright and colorful!

42. Expanding Soap

Watch what ivory soap does when you microwave it. Submerge a bar of ivory soap into water before cutting it into quarters and placing it on a plate. Pop it in the microwave for two minutes and watch as it expands into a pile of fluff!

43. Sticky Ice

Fill a container with water and ice cubes. Lay a piece of string across the container, ensuring the string is in contact with one or some ice cubes. Sprinkle salt over the string.

One minute later, gently submerge the ice cube slightly under the water to wash the salt off. Pick up the string, and you’ll notice that the ice cube comes with it!

This is because the salt melts the ice a little, and when you wash the salt away, the ice cube refreezes, attaching the string to it.

44. Density Jar

This is what I did my 5th grade science experiment on. Learn all about density with this cool and easy experiment.

Pour some honey into a jar, followed by corn syrup, dish soap, water, oil, and alcohol. The layers of liquid will sit on top of one another rather than mixing together!

45. Soap Boat

Cut out a mini boat about one-inch long using card or paper. Fill up a large tray or container with water. Dip a cotton swab into dish soap and place a tiny amount on the back of the paper boat.

Watch as it starts zooming around the water! This works because the soap breaks the surface tension of the water and creates a force strong enough to push the paper through the liquid.

46. Dancing Sprinkles

Place plastic wrap tightly over a bowl and secure it with a rubber band. Make sure there aren’t any wrinkles.

Pour a few sprinkles over the plastic wrap. Lean closely and hum songs near the bowl. The louder or higher you sing, the different sound waves you’ll create.

You can also try placing a speaker into the bowl before you place the plastic wrap over it. Once you’ve poured on your sprinkles, play a song and watch the sprinkles boogy!

47. Eggs and Salt Water

Fill a glass full of water. Fill a second glass all the way with water and add a bunch of salt. And finally, fill a third halfway with water.

Place an egg in the plain, full glass of water and watch as it sinks. In the salty glass of water, the egg floats. Finally, add salt to the third glass of water, allowing it to dissolve slightly before placing the egg inside.

What does the egg do? It floats. But if you pour water on top of it so the glass is full, the egg stays in the middle. This is a great science lesson to teach density to kids.

48. Leakproof Bag

Fill a plastic zippable bag half full with water and seal it shut. Stab a sharp pencil through the bag until it comes out the other side. Repeat with a few more pencils. Notice how the bag doesn’t leak water when you stab the pencils through!

50. Frozen Baking Soda

Fill a freezable tray with one cup of baking soda. Add three cups of water and food coloring. Mix well.

Add some figurine toys to the mixture and freeze the mixture overnight. Start pouring vinegar into the mixture as you try and rescue the figurine toys. The vinegar will slowly break down the baking soda with a fizzing reaction until you can break free the figurines.

51. Leaf Breathing

Fill three bowls with warm water. Place one freshly picked leaf in each bowl and hold the leaf down with a small rock. After a few hours, check back, and you’ll notice little oxygen bubbles all over the leaves.

These bubbles convey the oxygen coming out of the leaves. This highlights that plants breathe! They take in carbon dioxide and transform it into oxygen, which goes back into the air we breathe.

52. Exploding Colors

Fill a tray with baking soda. Fill an ice cube tray with distilled white vinegar. Add food coloring to the vinegar. Use an eyedropper to transfer the colored vinegar to the baking soda, and watch the colors explode!

53. Floating Paperclip

When you drop a paperclip into water, it will sink because it has a bigger density than water. But with this experiment, you can make it float!

Bend a paperclip to create an “L” shape. Balance another paperclip on the bottom end of the “L” shaped paperclip.

Gently lower the paperclips into the water, sliding out the “L” shaped one from beneath the second paperclip. The second paperclip will now float!

54. Viscosity Experiment

Fill three glasses with different liquids like water, olive oil, and honey. Place a ruler over the top of the glasses with a marble balancing above each glass.

At the same time, tip the marbles into the cups and watch which one reaches the bottom first. This is a great science lesson on viscosity.

55. Plastic Milk

Create your own plastic using milk. Pour one cup of fat-free milk into a saucepan with four teaspoons of white vinegar. Stir gently to combine.

Set the heat to a high temperature. Don’t stir. After a couple of minutes, the milk will start separating.

Gently stir the solution, and the milk will form a big curd called a casing. Voila! You’ve made plastic out of milk. You can mold and cut it into anything you want.

Stay Safe

Adults should help set the heat to a high temperature and stir the milk. Don’t leave your child unattended with this experiment.

56. Oxidation With Apples

Learn about oxidation with this fun and fruity experiment.

Get 10 plastic cups and pour ½ cup of water in all but one cup. Then add ½ teaspoon of ingredients to each water-filled cup, including vinegar, honey, salt, sugar, baking soda, and anything else you’d like to try.

With the help of an adult, cut up 10 apple slices. Place one apple slice in each solution for 10 minutes.

Remove them from the solution and wait another 10 minutes. Notice how the oxidation process varies depending on what solution the apple slice was exposed to.

57. Sunscreen Science

Using bright construction paper, fold each sheet in half and open it back up. Squeeze sunscreen onto a paper plate and use a paintbrush to draw a picture on one half of the construction paper.

On the other half of the paper, apply a spray-on sunscreen. Leave the paper outside in the sun for a few hours, ideally all day.

Notice how the sunscreen bleaches the part of the paper that doesn’t have sunscreen on it. But the sunscreen portion is protected! This is a great way to enforce the importance of sunscreen.

58. Static Electricity Hair

Static Electricity Hair

Teach your kids about electrons and negative vs. positive charge with this silly balloon experiment! Rub the surface of a balloon with a cloth for around one minute. Hold it slightly above your head and watch your hair move upwards towards the balloon.

59. Chicken in a Cup

Punch a hole in the bottom of a plastic cup. Attach a paperclip to the end of the ribbon and weave the other side through the hole so the paperclip is inside the cup. Dampen the dangling part of the ribbon slightly.

Hold the cup tightly in one hand and use your other hand to squeeze the ribbon and pull it down in sharp, short movements. All going well, it should make chicken noises!

60. Gummy Bear Osmosis

Pour water, coke, salt water, and white vinegar into four separate cups. Add one gummy bear into each cup and wait 24 hours. Remove the gummy bears and notice how they expand or stay the same depending on the liquid they rested in.

Top Tip

Weigh and measure the gummy bears before and after the experiment to track exactly how much they changed.

61. Make a Sundial

Make your own sundial to help you tell time! Start by poking a stick in the ground. If you live in the Northern Hemisphere, tilt the stick at a bit of an angle to the North. If you live in the Southern Hemisphere, angle it slightly to the South.

Every hour, take note of where the stick’s shadow is pointing on the ground. So, at 7 a.m., head outside and mark the shadow with a rock. Repeat at 8 a.m., 9 a.m., and so forth. As long as the sun is in the sky, you can use your sundial to tell the time.

62. Homemade Bouncy Balls

Combine ½ teaspoon of Borax with two tablespoons of warm water. Add a few drops of food coloring (optional). Then add one tablespoon of school glue to a separate bowl. Add glitter if you’d like.

Now add ½ teaspoon of the Borax solution into your glue, followed by one tablespoon of cornstarch. Stir well.

Once the solution has hardened, pick it up and mold it into a ball. Leave it to dry for 10 minutes. Watch it bounce!

63. Instant Ice

Fill a plastic bottle with water and place it in the freezer for two hours. Carefully remove it from the freezer.

Place a bowl or cup upside down and set an ice cube on top of it. Then, slowly pour the cold water onto the ice cube and watch instant ice form!

As an extra step, you can pour the cold water into a glass. Then hold an ice cube slightly into the water’s surface and watch as the water slowly freezes beneath it.

64. Mystery Smell

Get an adult or friend to fill up various opaque containers with different objects, such as chocolate, milk, vanilla, and other fragranced items. The children should put a blindfold on and sniff the different containers, trying to guess what is inside.

65. What Dissolves in Water?

What Dissolves in Water

This experiment is fantastic for learning what dissolves in water and what doesn’t. Drop some ingredients into various cups — oil, sugar, pepper, flour, and more. Then add warm water and stir.

Make it more fun by guessing beforehand which ingredients will dissolve and which won’t. Were your theories correct?

Safety Tips

It’s essential to stay safe during your science fair projects and experiments. Here are five tips for ensuring your child is safe while they meddle with science.

  • Stay nearby: Don’t leave your child unattended while they perform science experiments. Stay nearby without distractions to keep an eye on what your child tries out.
  • Wear protective clothing: It’s a good idea to wear a lab coat, glasses, and goggles while conducting experiments. Many ingredients, even natural ones, can irritate the skin and eyes.
  • Provide clear instructions: Before your child attempts a science experiment, ensure you have given them clear instructions, and they have a good understanding of what to do.
  • Only do approved experiments: The experiments on this list have been tried and tested many times. I urge you to stick with approved experiments. Don’t make up your own experiments, as many mixtures and chemical combinations can make toxic gasses.
  • Work in a well-ventilated spot: Some ingredients might cause nausea, dizziness, and headaches. So always work in a well-ventilated spot near an air purifier or open window.
