I have 0 photoshop/editing skills and I need to do this small extra credit assignment for my teacher or she'll feel bad. 
I'm in AP Environmental Science and the whole class does not care about the class or the AP Exam. I really don't care about this assignment but my teacher already gets the feeling the whole class doesn't care either, and I'm afraid she's already starting to feel bad. I've been playing sudoku in the class for about 6 months now, aside from doing the rest of my homework for classes I do care about. I know its mean but please help.

The theme is Water: a precious resource for all living things.
