If your child is self isolating due to Covid you can get free science kits for them. The kits, called Busy Bag Science, intend to keep youngsters busy and engaged in science whilst they are at home. Kits contain the resources and instructions for four experiments plus three colouring pages. They can be ordered from the Sciencedipity's website below and are posted 1st class to your home address:
The project runs for 4 weeks to mid March, and kits can be ordered for free any time during this period while stocks last.
