Uses of Energy - Lava Lamps

Select ALL the forms of energy needed to make a lava lamp work.

Place the steps below in sequential order of how a lava lamp uses and converts energy.

1. Once the density of the material is greater than the water, it begins to sink.
2. Electrical energy is used to turn on the lightbulb.
3. Light energy is produced by the lightbulb.
4. After the heated material floats to the top away from the heated lightbulb, it begins to cool, causing the density to increase.
5. The materials inside the lava lamp are heated at different rates, changing their densities.
