Great science experiments for kids 4-5 years old

I’ve found my 5 year old to be incredibly curious at the moment, always asking questions and wanting to know how things work. Even something as simple as a rain gauge has been VERY exciting for her.

With that in mind I’ve pulled together some great science experiments for kids that are perfect for 4 and 5 year olds.

Practice drawing or writing with fizzy paint.

Try some ice painting.

Make some filter paper butterflies.

Melt ice with salt and warm water.

Find out how many of your own feet tall you are. Is there a pattern?

For some icy play with a difference, freeze some water in a balloon.

This one might be a bit tricky, but try some apple bobbing and start to introduce the concept of density.

Learn about oil and water not mixing and density too with this density jar. Experiment with different objects floating on the layers to make it more fun. What happens when you shake it?

Make some shadow puppets and then put on a show. What happens to the shadow when you move it away from the light source?

How about making some simple ‘shooters‘ like Red Ted Art, what happens to them when it’s windy? Do they move further if you blow harder?

Can you make a mixture with your toys?

Try some colour mixing with jelly.
