Presentaions about the Earth-

All of them were really good. They had very complete information about their topic. The only thing I noticed was that they forgot about the citations. Some of them needed to be checked for spelling and grammar. It looks really bad if you have a nice presentation, but the spelling is poor. I noticed that some people had to much information on the slides, rather than having short bullet points and some pictures explaining your topic. My power-point is short. I like them short, because this way I can explain from what I know. It looks better if you lecture, rather read off a screen. I will add more facts for the audience so they can get and idea of what the natural resources and us humans are doing. I like power-point, because you can usefully display information. I've seen better!
