What do I want to learn in Global Science

I want to learn a bit about the environment we live in. I also would like to know how it works and what goes on behind the scenes. I think that it's really interesting to learn about the stuff that most people don't know about. I'm not sure what to expect in this class apart from what the description said but I hope that the class will be interesting because I like science. I am hoping for some hands on experience in the environment when it comes to learning about it.
