Earth Science Demonstration: Chocolate Plate Tectonics
Here is a plate tectonic demonstration/lab idea for all grade levels. You can easily use this video when teaching about earthquakes and plate movements. All you will need is a hot plate, pan, some milk and chocolate powder. Place the pan on the hot plate, pour in some milk, pour a thick layer of chocolate powder on top of the milk until the milk is covered. Turn on the hot plate and then wait a few minutes up to about 5 and you should start to see the "crust" break apart and "magma" rise to the surface. Extension in your conversation can be:
- Plate tectonics
- Cracks in the crust
- The "magma" turns brown due to the "crust" so you can talk about how igneous rocks get some of their characteristics due to the surrounding rock.
