[Science Fair Question] How do I measure energy?

Question

So for my science fair project, I'm going to convert various materials into energy i.e. petroleum, nonrenewable resources, etc. etc.
However, the results have to be graphable and I'm not sure whether how I would do it. I was thinking of trying to measure which of the materials have energy the most.

I'm not sure whether I could measure energy but I'm really confused as to what to do. I just know that I'm going to be converting materials into energy and that the results of the experiment have to be graphable.

Any suggestions or advice?? Help!!

Answer 1

You can use the old calorimeter method.

You take a measured amount of the material.... let's say 10 grams. You place it under a measured amount of water contained in a beaker. (let's say 50cc)

You burn the substance and measure the temperature raise of the water. That's the amount of energy contained in them transformed into the heat.

It's amazingly accurate if you are careful in all measurements and control the environment.
