Howdy!
I was your age when I got my 10" dob. It's a pretty neat instrument
I'm not really sure of what you could do. The asteroid Vesta is currently brightening and will reach its opposition at around the end of the month. Perhaps you could go out every night (or as often as the weather allows) and compare its brightness to that of a nearby star of constant magnitude such as Antares. Then you could record an estimated value for each night then at the end of the month compare it to the actual values of Vesta's magnitude. That wouldn't be answering a question per say, but its investigative I suppose.
