2Cut a rectangular slit on both sides of the box along the bottom.
4Along the top, poke a hole in the 4 corners of the box.
5Tie 1 rubber band around each of these holes.
6Loop the 4 bands around a marker and use one more rubber band to secure it in place.
7Adjust the height of the marker so it just barely touches the bottom of the box.
8Feed the paper strip through the slot while shaking the box to simulate an earthquake.
How It Works
When an earthquake occurs, a seismograph records earthquake activity. Due to the shaking, a pattern on the sheet of paper is created. These patterns provide information about the details of an earthquake, such as how strong it was and how long it lasted.

In this lesson, we learn that:
Earthquakes, tsunamis and volcanoes are a result of natural processes.
Earthquakes and volcanoes occur in patterns on Earth’s surface.
They are mainly found along the boundaries between oceans and continents.
Humans cannot eliminate these hazards, but we can take steps to reduce their impact.
