During science class the Seventh Age learned about earthquakes. We learned that earthquakes are measured on the Richter Scale and that when two plates in the Earth move they create a fault. During class, the students built small communities on a fault line. After the communities were created, I came around and moved the plates (the two pieces of paper) and rated the earthquake based on how long the community remained standing. The Seventh Age did a great job, most of the earthquakes were rated 3.0 or less on the Richter Scale.
