A science fair project normally begins with a problem statement and/or a question. If you are doing a display, I would probably look at my experiement and ask myself what kinds of questions I was trying to answer. For instance, I once did a science fair project that involved a compost pile. The "problem" or "question" that I asked myself was... What is the fastest way to compost organics? Then I made a hypothesis (or educated guess) on what I thought the answer might be and bam...I had a science fair project. I tested out my guesses and determined which thing worked best.
A good last minute science fair project for a 7th grader would be to make a volcano. Use vinegar and baking soda to put in the crater. This will bubble up and make it look like lava and smoke is coming out of the volcano.
