2. Question
What’s going to make the best lava lamp?

3. Background
The reason I picked this topic is because I’ve always loved lava lamps but i never got one. Doing this project teaches me how to create my own. Therefore, I can make my own lava lamp and make it unique.

4. Variables Independent - Amount of salt
Dependent - How many bubbles will appear
Constants - Amount of oil, Size of cup, Brand of salt
Independent variable-Isn't changed by the other variables you are trying to measure.
Dependent variable-Is something that depends on other factors.

5. Hypothesis
If I trail the experiment 3 times the 3rd time would work the best by how many bubbles come up.

6. Materials Salt Tap water ¼ cup of oil/vegetable oil Food coloring
Large clear glass
Eye Dropper

7. Procedure Fill The glass with tap water about ⅔ of the way
Pour the oil into glass
Add several different food coloring to water and oil
Slowly sprinkle 1 teaspoon of salt into the glass
Observe what happens
Repeat
Look over data to see what made the best lava lamp determined by the bubbles

8. Data

9. Conclusion
What’s going to make the best lava lamp? In this project i made a homemade lava lamp. I was going to figure out what made the best lava lamp by determining which time out of 3 had the most bubbles. In the end of the experiment i concluded that the second trial had the most bubbles. No my hypothesis wasn’t correct. My hypothesis was that the 3rd trial would work the best. I’ve learned making a lava lamp is as easy as salt,oil, and water. If I were to do this again I would change the cold water I used to hot water to see if anything would happen different.
