This just in... water issues!


We started by reviewing what we did last class: Compressor Diving. Mr. Pro was asking us questions
about the diving, and we had to answer him using the microphone.

Today, we did interviews/reports talking about water problems.

The topics were: Three Gorges Dam, Acid Rain, Amazonian Manatee, Pollution of River Tiete, and Flooding in São Paulo State. (You can click the links attached to each topic to do research each topic)

This is the timeline about how much time you will have to do each thing during class.

These were the questions asked in the interviews:
  1. Why is it a problem?
  2. Explain the cause of the problem and science related to the problem.
  3. Explain what people are doing to solve the problem.
  4. Explain how nature acts to solve the problem (challenge).  
  5. Explain & discuss other ways to solve the problem in the future.  

People got to choose their own groups and topics. 

Guidelines for the presentation

Here are people researching their topics, and creating their presentations.

These are pictures/videos of different groups presenting their reports. 

You can watch the video of Isabel, Ivanna, Kari, and Pau to get a good idea of what your presentation should be like. Also, if you watch this video, you can learn about acid rain.

At the end of each group's presentation, Mr. Pro gave everybody their grade and told them why they got that certain grade. He told them what they could improve next time to get a better grade.

While listening the the groups present, I learned about many things about each topic. For example, if people continue to poach the Amazonian Manatee, eventually it is going to become extinct. Also, heavy deforestation and gold mining is causing their habitat to get worse. Secondly, I learned that acid rain gets acidic from pollutants in the air. Acid rain is a type of acid deposition, and there are two types of it, wet and dry. Both of those can harm humans. If we stop polluting so much, then we won't have to worry about acid rain. Adding on, the Three Gorges Dam did create a lot of energy, but it was a danger to everyone and everything around it. As a matter of fact, of the dam breaks, then the millions of people who live near it could be killed. Also, the dam is triggering landslides, altering ecosystems, and causing many other environmental problems. Fourthly, the Tietê River is extremely polluted. It contains waste from 33,000 factories, and  sewage from 13 million people. Amazingly, only 4/5 of that water is treated. Finally, in Itaoca there was some major flooding, because it was raining a lot. 332 people had to be evacuated from their city, and at least 12 people were killed. The water in that city was over a meter high. I had a great time learning about all of these problems, and ways we could resolve them. Now, I have a great deal of knowledge about acid rain, Amazonian Manatees, the Three Gorges Dam, the pollution in the Tietê River, and the flooding that occurred in Itaoca.

  1. The first thing you could do to improve your post is to make a more creative title, instead of just ''Water''. Secondly, there is some repetition of the word ''people'' right after the 5 questions. Also, there were minor spelling mistakes, so you could revise your post again. Other than that, I think you included the most important information and the images were good.
