Science projects to try at home, especially if you can't get out and about
We've got more do it yourself science to try or National Science Week 2021, including some delicious ones based on our schools theme Food: Different by design.
We'd like to thank Jenny Lynch from Creative Science and Emma Donnelly from Comm-it for creating these activities for us. Other National Science Week contributors have DIY activities to try too - check out these ones from:
