How to determine if a substance is ethanol?

I'm in 8th grade- for science we're doing a project called sludge where each group of two kids is given an "unknown" substance which they have to find everything it is made of. My group separated the liquid from the solids and distilled the liquid so far through boiling it. We discovered that our first liquid had a boiling point of 79 degrees c. Apparently, the only liquid with that boiling point is the alcohol ethanol. However, to get full credit for discovering this, we must list the physical and/or chemical properties of ethanol and verify it. SO... how can I do this? What are ethanol's properties that are testable? (Flammable or not, smell, etc.) ?
