Layering Liquids Lab
Create a question: I want to find out what order water, vegetable oil, salt water, and rubbing alcohol would layer each other in a test tube.
Hypothesis: I think that the liquids will layer in this order from least dense to most dense.
1. vegetable oil 2. rubbing alcohol 3. water 4. salt water
Materials: You will need to have the following to do this lab:
1. Small test tube
2. Vegetable oil
3. Rubbing alcohol
4. Water
5. Salt water
6. Dye
7. 4 small measuring cups
8. Triple beam balance or scale
Procedure:
1. Get your four different measuring cups and get the liquids.
2. Use the scale or triple beam balance to weigh the different measuring cups. Record the weight in grams.
3. Pour 10 mL of each liquid into a different measuring cup.
4. Again measure the different cups now with the different liquids in them. Record the weight in grams.
5. Use the dye to put a different color in each liquid.
6. Get the test tube and slowly pour in each liquid separately.
7. Observe what happens and the way the different liquids layered themselves.
8. Create a chart that has the liquid, mass (g), volume (mL), and density (g/mL).
Safety: Make sure there are no electronics or papers near the liquids so nothing gets ruined. Also be careful no to drop anything that is glass.
Experiment and data:
Liquid- 1.Water 2. Salt water 3. Oil 4. Alcohol
Mass- 1. 16g 2. 17g 3. 15g 4. 14g
Volume-1. 15mL 2. 15mL 3. 15mL 4. 15mL
Density- 1. 1.06 2. 1.13 3. 1 4. 0.93
My results did not support my hypothesis because the way that the liquids layered wasn't the way that I thought it would.
Analysis/Conclusion: During my experiment we slowly poured the liquids one at a time into a test tube. We found that the slower you poured the liquids in the tube the more they layered. The way the liquids layered from least dense to most dense was water, salt water, vegetable oil, and then rubbing alcohol. My hypothesis was different from the results. The results were almost completely backwards from what I predicted it to be.
1. What conditions were controlled in your experiment?
The things that were controlled in my experiment was the measurements of the liquids.
2. What were the variables in the experiment?
The variables in my experiment was the types of liquids.
3. What liquid was the most dense? Why?
The most dense liquid was the rubbing alcohol because it sank to the very bottom of the test tube.
