No-Sweat Science: Earth Science Experiments

Tsunamis, hurricanes, global warming: more than ever, children want to investigate the forces that affect Earth - and learn how to protect our planet. And this engrossing collection offers a world of information and exciting activities. Through experimentation, young scientists will really understand how plants give off oxygen and why life couldn't exist without them. They'll build a seismograph; "play dirty" with soil, sand, humus, and mud; filter water; and find out how mountains are formed with the help of some clay and newspaper. Plus, kids will make a difference as they discover earth-friendly ways to save and reuse old clothes, toys, and other household materials. .
