Guide Questions: 1. What happens on the paper as you shake the cardboard box? 2. How does the image of the waves on the paper be affected when you shake the box harder? Softer? 3. What does it mean when the wavy lines on the paper are higher or lower? How could you use that to measure the magnitude of an earthquake?
