LAVA LAMP LAB
Question: What will happen when you mix oil, water, and an antacid tablet in a beaker?
Hypothesis: (What do you predict will happen?)
Supplies:

· Direction Dude(tte)
· Recorder
· Time Keeper
Procedure:
1) Using the graduated cylinder, pour 100 mL of water into the 400mL beaker.
2) Add 3 drops of food coloring – your group’s choice of color! Carefully swirl the beaker to evenly mix the color.
3) Carefully pour 200 mL of oil into the beaker so the liquids measure a total of 300mL. Let the oil settle into a layer.
4) Take one antacid tablet and break it into 6 smallish pieces.
5) Drop one piece at a time into the liquids, waiting a few minutes in between each piece.
Analysis Questions:
1) What do you know already / what did you think would happen when oil and water mix?
2) What actually happened to the water and oil when you poured the oil on top of the water? Is this what you expected?
3) What did you think would happen when you dropped the pieces of the antacid tablet into the bottle?
4) When you dropped the pieces of the antacid tablet (one at a time!) into the bottle, what actually happened?
5) What is produced when the antacid tablet is dropped into the water?
6) Did you notice a difference when you dropped in smaller or larger pieces? Which gave better results?
Conclusion:
7) Why did the oil and water form two separate layers? (Look it up if you need to!)
8) Why do the gas bubbles rise through the water and oil? (Think about your answer to the previous question...)
9) How do the colored water droplets move up and down through the oil?
10) What would your group do differently if you were to do this lab again?
Bonus: Why does Mrs. Thomas call this the Lava Lamp Lab?

Discuss: Why does the water always sink below the oil?

Discuss: What do you think the mystery powder is?
Why does the spaghetti "dance" (rise and fall)?
How is this like the lava lamps you created?
