Fun And Simple Experiments for Kindergarten Science You Can Easily Do at Home

Looking for fun science experiments for kindergarteners at home?

I’ve been there. And I know how frustrating it is to look for experiments that you want to do right now that don’t need lot of preparation (or a trip to the store).

I’ve got you covered.


Easy, Fun & Age-appropriate Science Experiments for Kindergarteners at Home

Here are some of the coolest at home science experiments for kindergarten age kids using only materials you already have in the kitchen.

Bookmark this page. Or pin on Pinterest.

Also, I would love it if you tell me in the comments section which ones you’ve tried (and if you’ve got a picture of it, we’d love to feature that on here, too!)

1. Upside Down Water Experiment

What kids do: Tip a drinking glass full of water upside down

What they learn: Kindergarteners learn about air pressure, surface tension and adhesion.

Text instructions:

This is so fun! In this experiment, we put a glass full of water upside down and the water stays in! Defying gravity? No. this is air pressure and surface tension in action

You will need:

  • drinking glass
  • water
  • thick card
  • a big bowl (optional)

4. The Walking Water Experiment: A Science activity on Capillary Action

Teach capillary action to kids using this running water experiment with paper towels. You can use white flowers toos.

What kids do: Make water “walk” from one glass to another

What they learn: How capillary action works. It’s also a good lesson on absorption and color mixing

Text instructions:

You will need:

  • 7 glasses
  • food coloring
  • paper towel 
  • water

5. Air Pressure Experiment

Can you carry a glass jar with a balloon? A fun quick science activity for kids to know how air exerts pressure.

What kids do: Carry a Glass Jar with a Balloon

What they learn: Air exerts pressure

This is a very easy and quick experiment that starts with a challenge.

Start by asking your child to carry the jar only with a balloon. This practices critical and/or parallel thinking. It’s also fascinating to see the different ways their minds work. 

After they try different ways to do it, you swoop in 🙂 and show them how it’s done.

First, put the balloon inside the jar.

Then blow on the balloon.

As you blow on it, the air inside the balloon will blow in all directions occupying all that space inside the jar. As you do this the balloon gets stuck so tight that you can pick the balloon up.

6. Surface Tension: The Scattered Black Pepper Experiment

Or the runaway pepper experiment. Teach kids about surface tension

What kids do: Make pepper scatter with a single drop of dishwashing liquid. Make it even more fun using glitter.

What they learn: This experiment shows kids one of the amazing properties of water which is water tension.

Text instructions:

Look at the pepper run for their lives at the touch of a detergent.

You’ll need:

  • ground black pepper

7. Leakproof Bag Experiment

Poke a bag of water with a sharpened pencil. NOt only is this experiment very insightful but it's also very colourful. Don't you just like the picture and amazingness of this?

What kids do: Poke a plastic bag full of water without the water leaking out

What they learn:  the Properties of polymers

It needs very few materials and is a truckload of fun. You will need

  • resealable bag like sandwich or plastic bags : note: paper bag doesn’t work
  • pencils
  • Water


  1. Fill the sandwich bag with water.
  2. Slowly poke the bag with the pencils.
  3. Watch what happens. No leakage! such a magical experience for many kids.

How cool.

This may look like a very easy science experiment but kids will have so much fun doing it. They’d want to keep doing it again and again so make sure you have a lot of pencils.

Also, be aware that taking out the pencils and seeing the water seep out is just as fun.

I have to admit that I didn’t know about this before until we tried it, so it was pretty cool when we first poke that bag and it didn’t leak.

This experiment explains the properties of polymers pretty well.

8. On Density: The Floating Egg

This is how you make an egg float - the experiment on salt water density.

What kids do: Make water denser using salt and make an egg float in it

What they learn:  Answer questions like why do you float in the Dead sea? Why are you lighter when swimming in the sea than in the lake? It’s a great science lesson on the density of saltwater.

Text instructions:

You will need:

  • salt
  • 2 drinking glasses
  • water
  • egg

What kids do: Bend water using a balloon

What they learn: See static electricity at work. How opposite charges attract each other

Text instructions:

In this static electricity experiment, we use balloons and other household items to find out which can bend the water the most (and what’s that got to do with positive and negative charges)

You will need:

  • balloon
  • a good set of hair 🙂
  • tap (faucet)
  • optional (other things around the house that you think behaves like a balloon
