The terrarium demo is a lab demonstration that allows students to actually see the relevant processes (radiation, evaporation, convection, and condensation) involved in the Earth’s energy transport. In essence, we simulate a mini Hadley circulation inside a glass aquarium. The construction of the terrarium takes some time and resources, but once constructed, the terrarium can be used multiple times for the demo with little preparation.
- What keeps the equator from getting hotter and hotter and the poles from getting cooler and cooler?
- In what ways is energy transferred around the Earth?
- What causes the Hadley circulation?
