Assignment 6: How things work

This is the sixth assignment, How things work. I really have no idea of what to do with this assignment or rather how to start doing it .. I got a few ideas but don't really see how I can do it .. first is the star trek 2009 .. i wanted to draw a diagram of the spaceship and label the parts and a short description of what the component does but the problem come about tracing the spaceship and totally trace it means not original .. so ya .. den I think and think and think until my younger brother come to me and ask me about this science homework about recycling .. and that was it .. so i draw a diagram illustrating the process of recycling water.
