Ok, sorry that questions sounds confusing, but I need 5 books for my references/citation for my research paper, but I don't have time to go to the library so I have to look up something online instead...so I was wondering, would Journal articles consider to be a type of book? do you think I can use it instead of a book? (doesn't journal article comes from a book of some kind? or maybe I'm just assuming that...)

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!!
