We find a ton of value in cheap science activities and experiments. All our science experiments use inexpensive, everyday materials you can find at home or source from your local dollar store.

We even have a whole list of kitchen science experiments, using basic supplies you will have in your kitchen.

You can set up your science experiments as an activity focusing on exploration and discovery. Make sure to ask kids questions at each step, discuss what is happening and talk about the science behind it.

Alternatively, you can introduce the scientific method, get kids to record their observations, and make conclusions. Read more about the scientific method for kids to help you get started.
