There are tons of things you could do that just incidentally use the matches, like as a pendulum bob. You could use the box as a battery holder.
The satisfying thing would be finding a question that actually interests you and running an experiment that addresses it. Are the aspects of the work you did in physics that really caught your attention? Were there any questions asked in class that the teacher didn't answer to your satisfaction?
This assignment is has the same problem as telling students to come up with a science fair project. Few will be inspired to do engaging science and you end up with a lot of vinegar and baking soda volcanoes.
It will be easier to help you find something engaging to do if start with a question you would like to answer.
