School Science Projects

especially if they tie in with the national curriculum. any key stage 1 teachers out there? what are you doing with your pupils this term? any good books you can recommend relating to this subject please?

I work for a library and I need to order books on Science Fair projects for Kindergardners. Most of the books we have are for kids that are 9 years old up through highschool age. I have many parents that come into the library looking for these kinds of books. Any suggestions?
