This book approaches the development of science fair projects from the point of view that science should be enjoyable, interesting, and thought-provoking. The scientific concepts introduced here will later help young students to understand more advanced scientific principles. These projects develop skills such as classification, making measured observations, thinking clearly, and accurately recording data. The 60 activities focus on topics related to environmental education such as collecting sensory data, migration, controlling environments, seeds, ripening fruit, predicting whether, force fields, natural dyes, soil erosion, friction, surface area and evaporation, solar heating, insulators, decomposition, and testing humidity. A glossary of science terms and an index are included. (DDR)
