Do any science teachers (or others) have any websites they would recommend for basic secondary school science?
Dd1 (9) has snaffled her older cousin's Lett's KS3 Science revision book and is working her way through it enthusiastically ("Cell division wow! Refraction way cool!"). I've bought her the Lett's question-and-answer book to go with it so she can test herself, but it would be great to have recommendations for some more interactive resources she can play around with.
Thanks in advance!
