Question

I have an Independent Research Project for next year and already start a letter grade lower because I started last year and didn't go through with it. I originally planned to test how temperature affects the formation of polyurethane foam. I ended up not really know how to really create a safe environment and I missed some deadlines so I decided to not do it. Now I need to get a grade worth an 'A' to make it through next year (as that will put me at a 'B'). Any ideas for good project ideas (experiments really)? (note: I also asked this in the chemistry section)
