The 20 environmental units here are divided into three broad categories (Our Planet's Resources, Our Planet's Natural Habitats, and Preserving Our Planet), and include such subjects as the atmosphere, water, energy, seas and oceans, rain forests, grasslands, urban environments, and waste and recycling. Each unit gives specific activities in library skills, arts and crafts, spelling and vocabulary, geography, math, music and theater arts, English composition, science, history and sociology, and other topics for discussion for grades two through eight. Suggested resources, additional reading lists and a list of addresses to write to for further information conclude each environmental unit.
