Janice VanCleave's Gravity 在线电子书图书描述

How are satellites launched into orbit?

Does gravity affect plants?

What causes the feeling of weightlessness?

Janice VanCleave's Gravity includes 20 simple and fun experiments that allow you to discover the answers to these and other fascinating questions about gravity, plus dozens of additional suggestions for developing your own science fair projects.

Learn about gravity and speed with a simple experiment using marbles and a ruler; about satellite launchings using clay, cardboard, and a marble; about gravity and plant growth with pinto beans; and much more. All experiments use inexpensive household materials and involve a minimum of preparation and clean up.

Children ages 8-12
