e candle), hot chocolate mix, water, spoon
III. Procedure:
1. Place the flat pan or tin ice cream can on the pan holder.
2. Fill the pan or tin ice cream can with water.
3. Add the hot chocolate mix to the water and stir with a spoon.
4. Light the candle and place it under the pan or tin ice cream can.
5. Observe as the heat from the candle causes the water to heat up and the hot chocolate mix to dissolve.
6. This demonstration simulates how heat from the Earth's core causes mantle convection, where hot material rises and cooler material sinks, creating movement in the mantle.
IV. Conclusion: Through this demonstration, we can see how heat plays a crucial role in the movement of material in the mantle, which ultimately drives plate tectonics and other geological processes.

Hot Chocolate Mantle Convection
I. Objective
To illustrate how heat works in the Earth's mantle.
II. Materials
- 1 flat pan (or 500ml tin ice cream can)
- 1 small candle
- Pan holder (higher than the pan)
- 1 cup of water
- 1 tablespoon of cocoa powder
- 1 teaspoon of sugar
III. Procedure
1. Fill the pan with water and place it on the pan holder over the lit candle.
2. Add the cocoa powder and sugar to the water and stir until dissolved.
3. Observe the movement of the hot chocolate as it heats up.
IV. Results
As the hot chocolate heats up, you will observe two convection currents:
- Upward currents: Hot chocolate near the candle flame becomes less dense and rises upwards.
- Downward currents: Cooler hot chocolate from the top of the pan sinks downwards and replaces the hot chocolate that is rising.
This circulation pattern creates a continuous flow of heat from the candle flame to the top of the pan.
V. Discussion
The convection currents observed in this experiment are similar to those that occur in the Earth's mantle. The mantle is a thick layer of rock beneath the Earth's crust. It is heated by the Earth's core and cooled by the crust. The hot rock near the core rises upwards, and the cooler rock at the surface sinks downwards. This convection current helps to distribute heat throughout the mantle and drives plate tectonics.
