Can some one help me with my grammar, and help fix my paper?

On November 11, 2013, I attended a Chemistry of Biological Systems, Material, Energy, and the Environment lecture presented by Dr. Zachariah Heiden. I went to this lecture, because I thought that it would be an interesting lecture. I also, attended the lecture, because in the jterm I plan to take chemistry 115, and in the spring semester, I plan to take material science. I went to this lecture with high hopes, that this lecture would spark my interest in chemistry, and in material science.

The start of the lecture Dr. Heiden talked about the chemistry departments a t the WSU. When he was talking about the chemistry department, just talked about what professor covered what part of the various chemistry departments. Then he briefly started to talk about four different researches that he was in the process of doing, but he only talked about one of them for ten minutes.

Through the ten minutes of discussing the research that he was doing he was using chemistry terms that I wasn’t familiar with, so it was hard to follow his lecture. He even tried to do chemistry math, but when I looked around, I found it that I was not the only person bored, and spacing off.

In conclusion, this lecture I wasn’t impressed with, because it didn’t talk about Chemistry of Biological Systems, Material, Energy, and the Environment at all. It was just a recruitment lecture that felt rushed, and was very unenjoyably to me, because I had hopes coming to the lecture, but was let down.
