A wonderful way for kids to experience the magic of science. The Experiment With series offers simple experiments that help children test and observe basic scientific principles. The whole family can get involved with these experiments, which are explained clearly and with the help of colorful photos.Grade 2-4-- Experiments and activities that don't quite succeed in introducing various science concepts. Many of the simpler projects, like making a cardboard model of an arm and elbow joint, are not interesting enough to excite most children; other, more involved ideas (making a periscope or an ``indoor rocket'') may intrigue some. The need for : adult help is appropriately noted. Many concepts, such as solar energy and inertia, are introduced within the text without much explanation and with no related projects. Readers learn what levers do, but not why or how they work. Gravity is discussed, but the accompanying experiment neither explains nor enlightens further.
