This is a introductory lab exercise that is intended to convey the concept of the logarithmic scale used for earthquake magnitude. The students will visualize magnitude as a distance over the ground, by using a contrived conversion between magnitude and distance. Using distances helps the students understand how logarithmic scales, like magnitude, work because this is one of the few scales that students are familiar with that spans several orders of magnitude. Students typically use calculators to determine the distance associated with each magnitude. Maps should be provided in the lab/classroom that are on several scales: campus maps, city maps, state maps, and a national map work well. This activity gives the students practice in making unit conversions and in developing arguments by analogy. Addresses student fear of quantitative aspect and/or inadequate quantitative skills Addresses student misconceptions
