Of all the disciplines the US has fallen behind in, we stand to lose the most from a pervasive lack of scientific understanding. These sites offer something for kids of all ages, including lots of learning games.
Also – don’t miss out on Sid The Science Kid’s site. Bee has loved Sid since it began – after seeing it a couple of times she requested her own observation journal. When a show has your 3 year old recording their observations – you don’t pass it up!
