Presents step-by-step instructions for one hundred science projects that use everyday supplies. This description may be from another edition of this product.
I have looked at several science fair project books and the ones I have seen have some pretty lame experiments. The experiments in this book are really interesting and novel. There are some cool biological experiments about plant and root growth. There is some cool stuff about batteries including lemon batteries (on the cover) and making metal coatings. I tried the generator but put it on a little windmill rather than making the hydroelectric generator that's in the book. It was pretty cool to make a generator out of knitting needles, cardboard, wire and magnets. The ideas form the basis for all electric motors - that's powerful stuff. [If you wind the wire around the "wrong" way then you only have to flip the coil over. ] The experiments are quite advanced (to the ones I've seen in other books) so to back it up on the day then you're going to have to know your stuff. However, the book explains what's going on and gives some more ideas to follow-up.
