Transcript of Copy of How do you collect methane gas from decaying fruits and vege

How do you collect methane gas from decaying fruits and vegetables?
Materials Needed
First you will need to buy these materials: 2 one inch pipes, 3 half inch pipes, 2 buckets with seal tight lids, primer and cement glue, ten foot of tubing, 2 clear jars filled with water,decaying fruits and vegetables, and a valve for each jar.
Procedure
1. Attach pipes to the lid of the bucket.
2. Primer the pipes and use glue to attach to lids.
3. Put the tubing on the end of the pipes to allow gas to flow to the jar.
4. Drill hole in lid of jar to allow tube in.
5. Fill the jar with water.
6. Put decaying fruits in bucket 1.
7. Put decaying vegetables in bucket 2.
8. Seal the lids tightly.
9. Collect the volume by bubbles per minute.
10. Turn valve on and off to allow bubbles out of jar.
Notation: If temperatures begin to drop, add a heater to enhance decaying.
The Fruits in Bucket One
Bucket one contained 10 pound of fruits for this experiment and it contained these fruits:
-Cantaloupes

-Watermelon

-Honeydew

-Pineapple
The Vegetables in Bucket Two
Bucket two contained 10 pounds of vegetables for this experiment and it contained these vegetables:
-Turnips

-Squash

-Cabbage

-Rutabaga

Bucket One Data
Bucket one's data was unable to be determined due to a leak found around day seven which was unrepairable due to not being able to fix the leak from the inside.
We expect that the cold weather caused the bucket to crack.

Bucket Two Data
Bucket two's data was determined by every five days observations.
Day 1- There was no signs of gas production.
Day 5- The jar had begun to lighting in color.
Day 10- The water in the jar began to whiten in color as the gas entered from the tubing.
Day 15- The jar had completely turned a light white in color.
It stayed this color for the rest of the experiment but never produced bubbles even once we added a heater.
Research

Hypothesis: The fruits will produce more methane gas than the vegetables.
