A collection of science experiments for elementary teachers, designed for use as individual and group activities and teacher demonstrations. Sections on subjects such as the physical world and ecology offer instructions, list inexpensive materials, and suggest questions, related activities, and vocabulary words. Most of the activities involve lengthy teacher discussion as the main component. B&w photos and illustrations show only two images of girls (one holding a baby), and one image of a boy in a wheelchair. Wire ring binding. Annotation c. by Book News, Inc., Portland, Or.
