All About Forces

April 1, 2016

Gr 1-3-These first surveys present clearly explained basic descriptions of select physical phenomena. Each succeeding concept builds on earlier material-in Light, for instance, a description of natural and artificial sources is followed by discussions of transparency, shadows, and reflection in succession-and three at least are reinforced in each volume by as many easy experiments. There are photos on every page, and most feature a diverse cast of children helpfully demonstrating relevant actions or processes. Occasional moot generalizations, such as a claim in Light that "light always travels in a straight line," can stand until students are exposed to higher-level physics. VERDICT Appealing first glimpses of physical principles and phenomena.
