描述
What is the best way to clean oil off feathers? How does soil erosion affect plant growth and food supply? Can the force in wind be used to generate electricity? The answers can be found by doing the fun and simple experiments in this book. Young scientists will explore the environment—the air, water, soil, pollution, and energy resources. For students interested in competing in science fairs, the book contains lots of great suggestions and ideas for further experiments.
