Mell What is a good conclusion for a lava lamp?
What are the results of a lava lamp? Conclusion and Results. We conclude that the more Alka Seltzer you put into the bottle of lava, the more it will be active. The more Alka Seltzer that is put in the bottle, the longer it will act on the vegetable oil, causing it to move.
What is a good hypothesis for a lava lamp?
Hypothesis:We think that adding oil, water, and food coloring together will make a lava lamp effect because we alredy know that water and oil separate because of their complete density contrast. The alka-seltzer will make it have a lava lamp effect.
What is the outcome of a lava lamp?
When they reach the surface, the gas bubbles pop and the water droplets sink back to the bottom—creating a lava lamp effect. Eventually the Alka–Seltzer tablet will be completely consumed, and the chemical reaction will stop. If you let the glass sit still, all the water droplets will sink back to the bottom.
What do you learn from lava lamps?
The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve. As it dissolves it makes gas, carbon dioxide. Gas or air, is lighter than water so it floats to the top.
What is the controlled variable in a lava lamp experiment?
The independent variable is the Alka-seltzer Tablets. The dependent variable is the water and the oil.
How do you make a lava lamp last longer?
Follow these steps carefully.
- Take a glass container. In most situations, a glass container is the most suitable solution when you want to make a permanent lava lamp.
- Add some oil. At this point, you should add some vegetable or baby oil.
- Pour some alcohol.
- Put the container onto the heat source.
Why is the lava in my lava lamp not moving?
A: If the lava in your LAVA® lamp isn’t flowing the way it should, try the following steps. Check the bottom of the lamp. There’s a metal coil that helps accelerate the melting of the lava. If this coil isn’t nestled at the bottom of the lamp, it may take longer for the lava to flow properly.
Can you make a lava lamp out of water?

What’s the difference between a lava lamp and a lamp?
Lava lamps consist of two insoluble solutions. In this demo we used oil and water to imitate a real lava lamp. The denser liquid will sink to the bottom while the other rests on top. Since water is denser than oil, it sank to the bottom leaving the oil on top. Real lava lamps contain a light bulb at the bottom.
What causes a lava lamp to float on top?
Conclusion. The heat caused by the lamp causes the denser liquid to float on top creating the “lava lamp effect”. We used to Alka-Seltzer to imitate this reaction. Adding Alka-Seltzer, creates carbon dioxide bubbles. These bubbles are less dense than oil, hence making them float to the top where they burst and sink back down.
How does the Alka Seltzer work in a lava lamp?
In short the Alka-Seltzer produces carbon dioxide, a gas, which bubbles in the layer of water. As the bubbles rise it carries the water up in into the layer of oil. The oil and water don’t mix so the water beads together into a “bubble” as it travels through the oil.
