This book includes 25 science activities in the fields of environmental science, soil science, life science, and physical science. The activities are designed to be used in outdoor settings. Each activity is composed of two parts--an explanatory section for the teacher and a student lab sheet. The teacher explanatory section begins with a brief introduction designed to give an overview of the activity's main concept. Materials required, preparation of materials, answers to student lab sheets, and super scientist activities are included. The environmental science activities include: testing biodegradability of litter, calculating air pollution, and identifying sounds in nature. The soil science lab experiences include: measuring water absorption and retention of soil, soil layering, and soil formation. Animal movement, animal and plant classification, photosynthesis, and absorption rate are included in the life sciences activities. Observing, measuring, filtering of rainwater, recording temperatures, and mapping the schoolyard are included in the physical science activities. The development of social, thinking, process, and cooperative skills are emphasized. Activities use inexpensive, easily available materials. (KR)
