My lab reports on how oxygen is affecting global warming and tested the percentage of oxygen in the atmosphere. This is a topic that I am interested in, and I have done similar research before.

The most difficult problem for me is that there is not much that can be done on the topic of global warming, so the report written cannot be particularly perfect. But I’ve done a lot of work on that, trying to include everything I can. 

I will give myself an 80, maybe I did not do very well in the report, but I tested many times and recorded it, and I tried to write down the impact of the change of oxygen, trying to make the report seem meaningful.
