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

Thermal energy is produced from the lightbulb being on for a while.
Electrical energy is used to turn on the lightbulb.
As one material heats up, it becomes less dense and floats toward the top.
After the heated material floats to the top away from the heated lightbulb, it begins to cool, causing the density to increase.
Light energy is produced by the lightbulb.
Once the material is back at the bottom of the lava lamp, the process repeats.
The materials inside the lava lamp are heated at different rates, changing their densities.
Once the density of the material is greater than the water, it begins to sink.

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

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

Electrical energy is used to turn on the lightbulb.

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

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

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

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

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