1. The process that forms oil requires a lot of time. How long ago did the oil we extract today start forming?
~ The oil started to form 200 million years ago.
2. What was the earth like at this time?
~ At that time there was more life in the sea.
3. We call it oil now, but what was that slimy black stuff before it became oil?
~ The slimy black stuff was algae, bacteria, and micro-organisms.
4. The video lists several processes or conditions required to change your answer to question 3 into oil. I think of five - can you get them all?
~ Algae, bacteria, micro-organisms sink to the sea floor.
~ Mix with other sediments creating air tight layer.
~ Pressure
~ Heat (60-120 degrees)
~ Time
5. Besides oil, what other fossil fuel can be formed by this process with only one minor variation?
~ Natural gas can be created.
~ The oil started to form 200 million years ago.

Oil and Natural Gas Lab:
Materials needed: lettuce, measuring cup, baggies, refrigerator, markers and a marker.
Goal: Replicate some (but not all) aspects of oil and natural gas formation.
Pre-lab questions:
1. What are some conditions required for there to be oil or natural gas production in the earth?
~ Oil requires conditions as:
- Algae, bacteria, and micro-organisms to sink to the bottom of the sea floor.
- Sediment Rock
- Capping stone
- Pressure (and heat)
- Time (200 million years to process)
2. Approximately how long does it take oil to form?
- Oil needs 200 million years to form.
Procedure:
1. Measure two cups of lightly crushed iceberg lettuce.
2. Place one cup of lettuce in a zip-lock bag and label the bag "warm." Place the other cup of lettuce in a zip-log back labeled "cold."
3. Distribute the lettuce along the bottom of each bag and roll the bags from the bottom to remove as much air as possible. Seal each bag.
4. Unroll and observe each bag now and each now and each day for the next two weeks. See the "observations" lab sheet.
5. Place the bag labeled "cold" in a refrigerator.
6. Note the temperature of the refrigerator and room.
Lab Questions:
1. What conditions are required for oil or natural gas to form are being reproduced in this lab?
Which conditions are not?
~ Conditions that are needed for the lab so that the oil or natural gas is produced was time and the temperature of where the bag is. Conditions that are not required is 200 million years and it didn't have to be placed in the sea to be formed.
2. What changes did you observe?
~ The warm bag was rotting very quickly and r\the cold bag was more preserved.
3. What do you except caused these changes?
~ The cause for the bags to be rotting or preserved was was due to the factors temperature and lack of little oxygen in the bags.
4. Was there any difference between the "warm" and "cold" bag? how do you think this relates to oil and natural gas formation?
~ Yes, the warm bag was rotting more than the cold bag. This relates to the oil and natural gas formation, because the warm temperature made the lettuce rot quickly with very little oxygen in the bag. While the cold bag wasn't rotting as quickly, because it was preserved in the cold temperature in the refrigerator.
