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

  1. Once the material is back at the bottom of the lava lamp, the process repeats.

  2. Thermal energy is produced from the lightbulb being on for a while.

  3. Once the density of the material is greater than the water, it begins to sink.

  4. As one material heats up, it becomes less dense and floats toward the top.

  5. Electrical energy is used to turn on the lightbulb.

  6. After the heated material floats to the top away from the heated lightbulb, it begins to cool, causing the density to increase.

  7. The materials inside the lava lamp are heated at different rates, changing their densities.

  8. Light energy is produced by the lightbulb.
