Science Experiment

Dose A Rubberband Shrink or Expand When Heated

A science experiment that I have done in the past would have to be one I did at this current intermediate school, we had an experiment that included a rubberband a lighter and a ruler. We first made a hypothesis on whether it would shrink or expand then Mr Marsh measured the rubberband then put a lighter not too far away from the rubberband but just far away to heat up the rubberband. After he had finish heating up the rubberband he measured the rubberband not twice but three times to get an accurate measurement on how long the rubberband was now. But Im not going to tell you what happened because I want to try it.
