Graham Cracker Plate Tectonics Lab: Introduction
The Graham Cracker Plate Tectonics Lab is a hands-on activity that simulates the movement of Earth’s tectonic plates. The purpose of the lab is to demonstrate the different types of plate boundaries and the forces that drive plate movement.
Materials:
- Graham crackers
- Frosting
- Sprinkles
- Knife
- Plate
Safety Precautions:
- Use a sharp knife carefully.
- Do not eat the graham crackers or frosting.
Plate Tectonics Concepts
Plate Tectonicsis the theory that Earth’s lithosphere, the rigid outermost layer, is divided into a number of tectonic plates that move relative to each other.
Types of Plate Boundaries:
- Convergent boundaries:Two plates collide, causing one plate to slide beneath the other (subduction).
- Divergent boundaries:Two plates move away from each other, creating new crust.
- Transform boundaries:Two plates slide past each other horizontally.
Forces that Drive Plate Movement:
- Convection currents:Hot material rises from the Earth’s mantle, causing the plates to move.
- Slab pull:The weight of subducting plates pulls the rest of the plate along.
- Ridge push:The force exerted by newly created crust at divergent boundaries pushes the plates apart.
Lab Procedure
1. Create the graham cracker plates:Break the graham crackers into pieces to represent the different tectonic plates.
2. Apply frosting:Spread frosting on the edges of the graham cracker plates to represent the subduction zones.
3. Add sprinkles:Sprinkle sprinkles on the frosting to represent the volcanoes.
4. Move the plates:Simulate plate movement by sliding the graham cracker plates relative to each other.
5. Observe the results:Note the different types of plate boundaries that form and the features that develop, such as volcanoes and mountain ranges.
Data Collection and Analysis
Data Collection:
- Record the types of plate boundaries that form.
- Measure the distance between the plates at different time intervals.
- Note the features that develop, such as volcanoes and mountain ranges.
Data Analysis:
- Compare the lab results to real-world plate tectonics.
- Identify the forces that drive plate movement.
- Explain the limitations of the lab.
| Plate Boundary Type | Distance (cm) | Features |
|---|---|---|
| Convergent | 2 cm | Volcanoes, mountain ranges |
| Divergent | 4 cm | New crust |
| Transform | 3 cm | Fault lines |
Discussion
The Graham Cracker Plate Tectonics Lab demonstrates the basic principles of plate tectonics. The lab results show that the different types of plate boundaries produce different features, such as volcanoes, mountain ranges, and fault lines.
The forces that drive plate movement are convection currents, slab pull, and ridge push. These forces cause the plates to move relative to each other, creating the different types of plate boundaries and the features that are associated with them.
The Graham Cracker Plate Tectonics Lab is a simplified model of the real-world plate tectonics system. The lab does not account for all of the factors that influence plate movement, such as the Earth’s rotation and the presence of water.
