Introduction: Dependence of Methane Production on Ambient Temperature in Bovine Waste The purpose of this experiment was to determine the effect of temperature in bovine waste on the amount of methane evolved. The hypothesis stated that the bovine waste heated to 48.9oC would produce the most methane. The manipulated variable in the experiment was the temperature of bovine waste. The responding variable was the amount of methane evolved from the waste. The experiment can be applied to real world

cupcakes more than the other methods. Research: It is the goal of every baker: creating the perfectly light and fluffy cupcake. However‚ it is a difficult task to complete. Many different methods have been recorded by various sources backed up by science. I have found three that I will test in order to find which produces the fluffiest‚ or least dense‚ batch of cupcakes. They allow for a greater leavening‚ or increase of volume of baking dough caused by the formation of gas bubbles. The methods to
