Summary

Solids, liquids, and gases-oh my! Learn all about the states of matter and fundamental physical principles with the fun science experiments in this book. Find out if you can make water flow upward, if carbon dioxide is heavier than air, and more! Many experiments include ideas students can use for their science fair.

Author Biography

Robert Gardner is a retired high school teacher of physics, chemistry, and physical science. Madeline Goodstein is a retired professor of chemistry. Thomas R. Rybolt has taught chemistry at the University of Tennessee at Chattanooga for more than twenty-five years.
