Lettuce Lab
Hey, guys! After the presentation Mr. Greg gave us, we did a lab. The goal of this lab is to replicate some (not all) aspects of oil and natural gas formation. The materials for this lab I will put down below. I'll see you later. Peace!
Pre-Lab Questions:
1. What are some conditions required for there to be oil o natural gas production in the earth?
> What it says on question #4 in the oil notes tab.
2. Approximately how long does it take oil to form?
> 200 million years
Materials:
1. Lettuce
2. Measuring cup
3. Baggies
4. Refrigerator
5. Markers
6. Thermometer

3. Baggies

5. Markers
6. Thermometer
Procedure:
1. Measure two cups of lightly crushed iceberg lettuce 2. Place one cup of lettuce in a ziplock bag and label the "warm". Do the same for the other cup of lettuce and label it "cold". 3. Distribute the lettuce along the bottom of each bag and roll them to remove as much air as possible. Seal each bag. 4. Unroll and observe each bag now and each day for the next two weeks. See the observations lab sheet. 5. Place the bag labeled "cold" in the fridge. 6. Note the temperature of the temperature of the fridge and the room. |

Lab Questions:
1. What conditions required for oil or natural gas to form are being reproduced in this lab?
> The conditions needed are the refrigerator and the outside area. They put all the warm-labeled lettuce in the outside area and the cold-labeled lettuce into the fridge.
2. What changes did you observe?
> After getting the bags back, my table and I noticed that the warm lettuce turned into a big bag of brown lettuce barf. The cold lettuce still looked fresh as the day we put it in.
3. What do you expect caused these changes?
> I knew it was from putting them in different areas. The cold bag was preserved in the fridge while the warm bag was left outside with no type of preservation at all.
4. Was there any differences between the "warm" and "cold" bag? How do you think this relates to oil and natural gas formation?
> NO, of course not. OF COURSE THERE WAS A DIFFERENCE! If you want to find the relations between oil and natural gas, go look at the pervious pages on my website.

Well, seems like you're done reading everything. I'm done here so I got to go. I'll see you later. Peace!
