Bubbling Lava Lamp

Bubbling Lava Lamp

Problem:

It all started with just 2 simple ingredients to get my homemade lava lamp to work and just a little bit of heat and light. Each element helped create this lava lamp to become something cool and exciting to look at. But what really made this lamp turn into a real working lava lamp? Adding more dye affects the amount of bubbles in a lava lamp.

Hypothesis:

Adding more dye affects the amount of bubbles in a lava lamp.

Experiment:

1. Adding the same amount of water and oil to each of the beakers

2. adding 3 drops of dye to one of the beakers

3 have a flashlight underneath each of the beakers for a full affect

4. See the difference in each of the lamps

Materials:

1.  2 beakers (same size)

2. Any kind of oil

3. Water

4. Food coloring

5. Flashlight

6. Seltzer

Observations:

Lava lamp 1:   The lamp that doesn’t have the coloring has a smaller number bubbles than the one with dye.

Lava lamp 2: The lamp with the dye has more of a colorful effect with the heat and the bubbles. When we first added the seltzer, the gas bubbles had carried the water on the bottom to the top because it became less dense. Water and gas is less dense than oil. When the gas bubbles popped, the water became more dense.

Using seltzer added the bubbly effect rather than just having water on top of oil with food coloring.

Data:

For when we did the experiment with just water,oil and seltzer we got less of a reaction with the bubbles. This did not give it a lava lamp effect to it. When we had the experiment with the food coloring, water, oil, and seltzer it had more of a gas effect. having the bubbles start out big to the top and getting smaller as it decreased.

Conclusion: Having dye in the lamp has more of a colorful effect on the bubbles and how dense it got. Then having just water, oil and seltzer. Giving it more of a lava lamp effect.
