Directions: Record all highlighted parts in your science notebook.

1. Set up the material at your desk like the picture above.

2. Draw the set up in your science notebook.

3. Predict what will occur within the jar. Show parts 2 and 3 to your science teacher.

4. Light the candle and make observations with a flashlight.

5. Draw the observations of what happened in the bottle. Draw the observations in the diagram in your science notebook with arrows showing motion. Label the parts and in parenthesis include the part of the Earth they represent.

6. Complete the reflection questions.

Reflection Questions:

1. How is convection occurring in the jar?

2. How is your demonstration representing the interior of the Earth?

3. What effect do you believe moving magma will have on the earth’s crust?

Part 2: Mantle Convection

Use the diagram below to answer the questions about mantle convection in your science notebook under your convection bottle work.

Before you answer the questions copy and color the diagram in your science notebook. Copy the questions or answer them in complete sentences.

1. What layer(s) of the earth has convection currents moving around?

2. What can you infer about the state of matter of this part of the Earth? Explain your answer.

3. What part of the earth must be heating the mantle?

4. Where is the magma (this is what makes up the mantle) cooling? What happens to the magma once it cools?

5. Where is the magma least dense? Where is the magma most dense? Explain.

6. What effect do you think the moving magma has on the layer above it, the crust?
