A lava lamp is not a chemical reaction. It operates based on the principles of heat transfer and density changes. The movement of the wax and liquid in the lamp is due to the heat from the bulb causing the wax to expand and become less dense, allowing it to rise, and then cool and become denser, causing it to sink.
A hypothesis for making a lava lamp could be: "If I combine oil, water, and effervescent tablet in a bottle, then the chemical reaction will cause bubbles to form and rise to the top, creating a lava lamp effect."
The problem statement of a homemade lava lamp project could be: How can we create a visually appealing and interactive lava lamp using simple household materials and a safe chemical reaction to mimic the rising and falling motion of blobs in a traditional lava lamp?
Adding Alka-Seltzer to a lava lamp causes a physical change because it does not alter the chemical makeup of the substances, only the appearance and behavior. The fizzing and bubbles are a result of a physical reaction caused by the release of gas, rather than a chemical reaction.
A lava lamp demonstrates a physical change. The wax in the lamp changes states from solid to liquid and back to solid again as it is heated and cooled, but the chemical composition of the wax remains the same throughout the process.
Yes you can use alka seltzer to make your own personal lava lamps. It doesn't matter what kind you use as long as it fizzes with the oil and the water.

The chemical structures remain unchanged.
Yes. The temperature of the liquid and the wax both affect the action of a lava lamp.
Paraffin, solvent, dye.
No. This is simply a change of state from liquid to solid. It is a physical change.

A lava lamp demonstrates a physical change. The wax inside the lamp changes states from solid to liquid due to the heat of the light bulb, but its chemical composition remains the same throughout the process.
Switch it on i think, which would heat up the hardened wax at the bottom of the lamp and melt it so that it floats up to the top of the lamp in a process called convection, then when it reaces the cooler top of the lamp it will cool and sink to the bottom then repeat these steps again. But if you wanted a more exciting reaction you could put the lava lamp on a hot stove, but this is a very dangerous reation as it will probably explode violently, as proven in an episode of mythbusters.
Yes, the temperature of the water can affect the reaction of a lava lamp. The reaction is driven by the heat from the light bulb at the base, which causes the wax to rise and fall. Warmer water can help the wax heat up and move more fluidly, while colder water may slow down the reaction.
