Cow Manure for Energy

Kyra and Noelle



For our science fair project we are using cow and horse manure to make energy. What we are doing is mixing cow manure with water and putting it into a bottle. Next we will run a tube out of the top of the bottle into another bottle. We then put the tube at the top so that the gas goes into the tube and into the other bottle. The other bottle has another jar inside of it. The bottle is halfway filled with water. When the gas comes into the bottle it goes into the jar and the gas pushes the water out. When all the water is out of the jar that means that the jar is filled with methane gas. From there we are going to see how much gas we can get out of cow manure and horse manure. So we will use a Bunsen burner to measure how much gas we get and what color the flame is. To get the gas into the burner we will have a T in the tubes so that we can turn a valve and have the gas come out into the Bunsen burner tube. When we light the burner we then time how long the flame lasts and what color the flame is. When we do this the first time we empty it out the jarand do not use the gas because it will mostly be CO2. We will then repeat this 2 or 3 times to test the gas.
