Experiments with solids, liquids, and gases

Gr 1-3-A new subset of a key series, these latest titles do not meet the expectation of solid reliability. Each brightly designed book contains directions for demonstrations or experiments (requiring modest expenditures for materials and equipment) and boilerplate introductions to the scientific method, proper techniques, background information, and safety advice. Small but clear color photos show scientists in the field, relevant items or forces at work, and children performing each activity. Unfortunately, some projects come with badly stated hypotheses ("A plant will be able to grow if part of its root is cut off") or poor design (such as a demonstration of momentum that assumes a skateboard will roll straight down a narrow board), and the "True Statistics" included in every volume contain moot tallies, such as "number of permanent magnets in your home or car: 50."
