Lava Lamp Experiment

Front

What is a lava lamp?

Back

A lava lamp is a decorative lamp that contains a colored wax-like substance that moves in a liquid, creating a flowing effect when heated.

Front

What is the main liquid used in a lava lamp experiment?

Back

Water is the main liquid used in a lava lamp experiment.

Front

What is the purpose of oil in a lava lamp experiment?

Back

Oil is used because it is less dense than water and does not mix with it, allowing for the lava lamp effect.

Front

What happens when you add Alka-Seltzer to water in the experiment?

Back

Alka-Seltzer reacts with water to produce carbon dioxide gas, creating bubbles.

Front

Why does oil float on water?

Back

Oil floats on water because it is less dense than water.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, determining whether it will float or sink in another substance.

Front

What is the role of heat in a lava lamp experiment?

Back

Heat causes the wax-like substance to expand and become less dense, allowing it to rise.

Front

What happens to the bubbles created by Alka-Seltzer in the experiment?

Back

The bubbles rise to the top, carrying some of the colored liquid with them, creating the lava lamp effect.

Front

What is the effect of temperature on the density of liquids?

Back

As temperature increases, the density of most liquids decreases, causing them to expand.

Front

What safety precautions should be taken during the lava lamp experiment?

Back

Avoid ingesting any materials, handle hot water carefully, and do not shake the bottle.
