//Time:// 1 period, 45 minutes //Scope and Sequence:// Show students the earthquake videos on teacher tube. Ask, "Does anyone know what causes earthquakes?" Chart responses.

"Today we are going to discover what causes earthquakes." Give partnerships different clay colors or fabric colors. Have them make flat sheets of it and layer them on top of each other. Model making the first two layers and then walk around assisting groups.

"Now that we all have our layers of clay, we are are going to put one hand on each end of the stack and push towards the middle. What happened? If the layers of clay were layers of rock on the earth's surface, and you forced the clay together, what do you think would happen?"

<span style="font-family: 'Comic Sans MS',cursive; font-size: 12pt;">"Rock layers push together in the Earth's crust because of pressure. This is called convergent movement. Are there any cracks in your clay? These are called joints. Rock layers can shift at joints. If movement has occurred there, we call these faults. Let's add convergent movement, cracks and faults to our glossary in our science notebooks."

What did you think caused earthquakes? What did you discover in this activity? How was it different from your prediction? How do earthquakes affect the Earth? How do they affect people?

<span style="color: #000000; display: block; font-family: 'Comic Sans MS',cursive; font-size: 12pt; text-align: left;"> Create a chart of effects once students are done.

Were they able to describe it in words? <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 14pt;">** HOME **
