The 'lava' in a Lava Lamp is actually a chemically treated wax. The clear (sometimes colored) liquid is water. When the lamp is turned on the metal coil inside the glass chamber is heated by the light bulb. The reason it sinks and rises is because when the molecules inside the wax get heated up and speed up and expand. This causes them to become less dense than the water causing them to rise. When they are at the top the molecules slowly get colder and they slow down which makes them more dense than the water, so the wax sinks.
A lava lamp is a pretty interesting thing, when it is cool, it looks like it's made of candle wax, because it is. Wax is strange, because when it is hot, it rises, but when it is cool, it sinks, so the bulb at the bottom heats the wax, and it floats to the top, but at the top, when it starts to cool down, it sinks. cool huh?
Inside a lava lamp there is wax.
A Lava lamp is amixture of compounds.
I am a former student and i did this project in the 7th grade and i got 1st place so the conclusion is that when the lava sinks and floats those are chemical reactions.
what is the controlled variable in a homemade lava lamp
this is like warm, less dense air rises while cool more dense sinks. This is like the lava lamp the hot "lava" floats up to the top and and the cooler "lava" sinks down to the bottom and heats up and rises and the cooling stuff at the top is now sinking

Convection is when hot substances rise and cool ones sink. The colored wax heats up at the bottom of the lamp where the bulb is, then rises up, cools, and sinks again.

how to make a graph for a lava lamp
Convection currents. The hot wax is less dense so it rises. When it reaches the top it begins to cool, becoming less dense and it sinks.

It depends on the size of the lava lamp
what is the controlled variable in a homemade lava lamp
Well there is a metal springy at the bottom of your lava lamp, It helps heat the lava (wax) in the bottle.
One suggestion for the cause of plate tectonics is mantle convection which is the result of cooling and heating magma. You could think of mantle convection much in the same way lava flows in a lava lamp. Lava rises in a lava lamp because it heats up and becomes less dense. While at the top of the lava lamp, the heated lava begins to cool (because it's further away from the heat source (e.g. light) at the bottom) becoming more dense and then sinks back down to the original heat source where it will be reheated. This mantle convection is thought to work somewhat like a large conveyor belt in which the plates sit, moving them along.
