This guide is designed to provide teachers (grade 2) with a ready resource for planning, organizing, and teaching science to the elementary child. Many suggested activities will provide an enriched science program. Each unit lists estimated time, content, concepts or "understandings," problems to deal with, activities, suggestions for evaluation, audiovisual aids, and additional references. The topic headings of the 11 units are as follows: Seasons; We Do Work; Sounds and Senses; Trees; Rocks and Minerals; The Big Round Earth; The Earth's Gravity; Electricity; Work and Play with Magnets; Animal Babies; and Good Food, Good Teeth. The units were written primarily for second graders, but many of the activities would be appropriate at other elementary grade levels. (JP)
