I originally created these science experiments for parents at home with children during lockdown 2020, but they work well as science activities for home or school at any time of year.

The idea behind Tray a Day is that everything you need for the activity fits in a tray, so it’s easy to set up and easy to tidy away.

science at home experiment - paper spinners - easy science for home and school

Each one uses materials you probably already have at home ( mostly paper and cardboard ) and should be easily enough for older children to do with just a little supervision or younger children to do with adult help.

Another idea is to find an answer to a fun science question, do you know why the sky is blue or why we have leap years?

If you have small children these easy non-messy science experiments are perfect for little ones!

I also have some science books available if you’re still looking for more inspiration.
