A review by bookgirl4ever
Leon and the Champion Chip by Allen Kurzweil

2.0

In 4th grade, Leon (chip aficionado) created a sort of voodoo doll of a teacher that really worked, making her act even more unusually than ever. During the summer before 5th grade Leon attempted another doll of the bully that harasses him. Try as they might, Leon and this friends can't figure out why the doll doesn't compel the bully to do the actions they make the doll do. In comes the new science teacher who uses potato chips to teach the kids about science experiments and inspires Leon to keep trying to figure out what he is doing wrong.

Too odd for my tastes, but I do have admiration for the science teacher's attempt to excite his class about the scientific method.

Upper elementary.
