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; filter water; and find out how mountains are formed with the help of some clay and newspaper. Plus, they’ll discover earth-friendly ways to save and reuse old clothes, toys, and other household materials.
