50 Kitchen Science Experiments for Kids

The kitchen is a great place to explore science with children. Even something as simple as melting chocolate is a great science experiment. You can cook, bake, set up a sensory activity, create science magic, make lava lamps and volcanoes, or even play with ice. The creative opportunities with this collection of kitchen science experiments are endless!

The best thing about science in the kitchen is that you probably already have everything you need!

Kitchen Science Experiments for Kids

Egg Experiments

There are so many different things you can do with eggs. Learn about strong shapes, dissolve the shell in vinegar, transform egg white into meringue and make an egg float with these awesome egg experiments.

Kitchen Science for Preschoolers

My preschooler loves gloop or oobleck; if you’ve never made it before, you must try it. The cornflour ( cornstarch ) and water mixture feels solid if you squeeze it but turns into a liquid when the pressure is released.

Use eggs to learn about tooth decay.

This density experiment will impress everyone. Finding a small object to balance on each layer is an extra fun challenge.

Sweet Treats

Create a Bake Off worthy masterpiece with the Science Sparks Bake off! Find out why honeycomb has bubbles, why cakes turn brown and more!

Can you believe meringue is made from sugar and egg white? Little scientists can transform egg white into a lovely sweet treat.

Discover the power of baking soda by making pancakes!

Making treacle toffee is a great activity for learning about changes of state as the sugar melts and then becomes solid again. Be very careful with the hot mixture, though.

Try some colour mixing with jelly. This is great fun, and you end up with a fun dessert after the investigation.

Grow some sugar crystals and make a lolly.

Find out why popping candy pops or try one of these other candy experiments kids will love!

Savoury Kitchen Science

Make a pizza to learn about respiration and yeast. Breadmaking is another fun activity to see yeast in action.

Make a baked Alaska to find out how to put ice cream in the oven without it melting.

Make some yummy honeycomb and discover why it has holes.

Can you make your butter from cream?

This activity is excellent for learning about colloids. It takes a bit of time and some energy, but the end result is worth it.
