Science Gifts For Kids?

beernutmark writes "I have two science-loving kids ages 7 and 9. My youngest knew Neil deGrasse Tyson's name at age 4. With the holidays coming up, I am looking to get them some quality science-related tools. Two items on the list are a quality microscope and/or a real rock-hounding kit. I am looking for any other gift suggestions for this year or future years (or even for younger kids for other readers) and hints on good sources."
