This learning module looks at earthquakes. It discusses areas of earthquake activity, how they are measured using the Richter scale, and how scientists try to predict earthquakes. Includes handouts, slideshows, activities, and videos.

In this activity, students will learn about the Mercalli Scale for rating earthquakes. Also, students will make a booklet with drawings that represent each rating of the scale.

A calculator to show the difference in magnitude between earthquakes. Understand that the Richter scale used to measure earthquakes is base-10 logarithmic scale.

Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. They make a model of a seismograph - a measuring device that records an earthquake on a seismogram. Students also investigate which...
