Presentations

Today I graded Laura's Presentation. She talked about the water pollution as I did. She has a very nice presentation, she explained what is water pollution, its mortal effects, and why is it so important to us. My presentation is very similar as Laura's PowerPoint, but I talked about why water keeps us alive, the harmful effects of water pollution and how we can prevent it. If I would have to do it again I would write more information and study what I'm going to say when I have to present it.
