This is a good book for parents to use along with their elementary school aged kids. It does a pretty good job of compiling a good selection of simple experiments that teach basic scientific principles. I remember I used to love it when I was in school. It taught me a lot about science. From the front: "Easy-to-do, remarkable, magical projects including -a bubble blower -a bottle barometer -your very own rainbow -invisible ink -a directional compass -a string grandfather clock -Dracula's favorite soap -rock candy -canned laughter And master the arts and skills of -the egg in the bottle trick -pulley power -an air polution test, and 353 more!"
