1. The process that forms oil requires a lot of time. How long ago did the oil we extract today start forming?
- 200 million years
2. What was the earth like at this time?
- The land was like one big blob and the rest of the area was water.
3. We call it oil now, but what was that slimy black stuff before it became oil?
- Phytoplankton was used to create oil.
4. The video lists several processes or conditions required to change you answer to question three into oil. I can think of five - can you get them all?
-1. Phytoplankton die and sink into the ocean
-2. They mix with other sentiments
-3. Rock layers on top of it and generates heat
-4. Between 60 and 120 degrees Celsius, oil is formed
-5. It boils over 200 million years and creates oil
5. Besides oil, what other fossil fuel can be formed by this process with only one minor variation?
- Over 150 degrees Celsius, natural gas is formed.
Continued Notes
Plants and photosynthesis animals (diatoms)
- Matters that made up the fossil fuel.
Anoxic environment
- Required for chemical energy to be retained, avoiding decompose.
Pressure
- Concentrates plant and animal matter & generates heat
Heat
- Converts plant and animal matter to fossil fuel
Capping Stone
- Traps lighter oil
Time
- 100's of millions of years
- 200 million years

Lettuce lab
Materials:
1. Lettuce
2. Measuring cup
3. Baggies
4. Refrigerator
5. Markers
6. Thermometer
1. Lettuce
2. Measuring cup
3. Baggies
4. Refrigerator
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 kinda brown-ish lettuce barf. The cold lettuce still looked fresh with a little red spots on it.
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?
- Oh it's a big different. We always put vegetables inside of the fridge to keep it fresh, who would put it outside? We don't want it to be rotten. But when it comes to oil forming, we need heat to convert it. That is the difference.
