Hi Jon, I just joined today and saw your post. I congratulate you for encouraging your children to like science. There is the most amazing science website from which you can order a whole heap of stuff. It is especially designed to encourage children of all ages form prep to yr 12 to like science by providing a range of really cool, relatively inexpensive gadgets from "peephole" glasses which you hold up to your eye and it splits any light source you look at into the spectrum colours to mouse trap cars to torch light powered gadgets you can connect your ipod to hear the sound from some speakers. The website is http://www.profbunsen.com.au. Just have a look and some fun regards like chem
