I apologise for some of the 'not serious science' stuff I have been posting in the main board - I am not trying to turn SAGG into a science 'trivia' site...
...but here's another link.
I have been thinking about how I can best get my daughter thinking for herself and stimulate an interest in her surroundings and although she is still three it seems to me that the earlier the better.
I came across the following page and think it is an ideal way to give her an opportunity to experience a sense of wonder with science. It may be helpful for other parents too. They are a series of simple science toys and experiments that are easily and safely done at home with your kids, like creating a Magnetorheological fluid (one that appears solid in the presence of a magnetic field and then becomes fluid when the magnet is taken away).
