Final Exam
Use one of the following variables to design an experiment pertaining to your biogas generator: 1.) Temperature
2.) Slurry Mix
3.) Consistency
4.) Surface area
5.) Light Intensity
6.) Percent cow manure
7.) Volume of Slurry/Volume of bottle ratio

Experimental Design (70 points)

Title| How the Volume of the Slurry Mix Effected the Biogas Generator| Type of Experiment| Experimental |
Background Information| Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane, the main component of natural gas, and probably the most abundant organic compound on earth. For this experiment we had created a bio gas generator. A biogas generator is any gas fuel derived from the decay of organic matter, as the mixture of methane and carbon dioxide produced by the bacterial decomposition of sewage, manure, garbage, or plant crops. Using a slurry mix of manure and cut grass we came up with the hypothesis “The more volume of slurry, the more gas will be produced”. Our independent variable was the volume of slurry, because we controlled how much slurry to put in the bottle, and the dependent variable was the methane gas.| Problem Statement| How Does The Volume of Slurry Mix Effect the Process of Methane Gas?| Hypothesis| The More Volume of Slurry Mix, The More Methane Gas Will Be Produced.| Independent Variable| The Volume of Slurry Mix|

Dependent Variable| The Methane Gas|
Experimental Tests| 5 trials|
Number of Trials per Test| 1 trial per test|
Control Test| Volume of slurry|
Variables held Constant| The amount of water used|
