How?: More Experiments for the Young Scientists

A companion volume to the Prochnow's "Why? Experiments for the Young Scientists", this book is filled with safe, easy, inexpensive experiments that encourage students to ask how scientifc phenomena take place. Each a self-contained lesson focusing on specific natural or man-made occurrence, these projects serve to teach children learning skills like following directions, observing, and recording information, as well as to stimulate further interest and inquiry into the sciences. How does helium make a balloon rise? How do crystals form? How does exposed film produce a photograph? How do thunderstorms develop? How does light make a plant grow? These are just a few of the questions answered by this outstanding collection of science experiments.
