Self-evaluation report

   During this project I think I got an improvement of my efficiency. We started our first experiment early than our deadline so time for us is plenty there. 

   First, we tried an experiment about sounds’ patens. There’s a video for us to reference. But why it can define it as “our experiment” is because we truly learned new knowledges from it. There’s no the suitable reflector so we used a big triangular prism to instead of it. That’s also the reason why we hadn’t succeed finally. After meeting our problem we asked some help from blue. Then got the idea of the excessively heavy and tried some other objects to changes this. I think it can complete prove that we were clear whit the theories of this experiment.

   But there are still some problems. Like why I hadn’t send my homework until now​, Okay, I knew I still need to improve my efficiency.
