The 112 activities in this book cover every aspect of the natural world, including plant and animal life, weather, ecology, rocks and minerals, the senses, the stars, and much more. You'll build a mountain the same way the earth does, find out whether your neighborhood ants prefer sugar or artificial sweetener, discover why maple seeds act like tiny helicopters, and explore the effects of acid rain on plants--all with the help of a leading educator.
