图书描述

Going green is a hot topic…and a hot science fair project. Author and scientist Elizabeth Snoke Harris knows what impresses, and she provides plenty of winning ideas, along with step-by-step guidance to insure that the end result is a success. Show how to harness energy with windmills, make a biogas generator, and create alternative fuels. Demonstrate green power with recycled paper, solar building, and compact fluorescent light bulbs. Test the ozone, be a “garbage detective,” and discuss how to reverse global warming.

The importance of what children learn will go even beyond the science fair: they’ll have the knowledge to understand what’s happening to Planet Earth…and the desire to do something eco-friendly every day.
