Change Is My Game

Find out about the many ways the earth changes, both quickly and over time. When reading about weathering, you can do an experiment with frosted pastry to see how upward pressure from plant roots can break down the earth’s surface. Learn about uplift by experimenting with a Snickers bar. Simulate your own earthquake. Do an activity that clearly illustrates geologic time by unrolling a roll of toilet tissue. The photographs are stunning, the graphics illustrative, and the information is excellent. Take a trip through the Grand Canyon, identifying the layers as you go based on the mnemonic provided.
