16. In Class Assignment
In Math class, we are focusing on the water crisis affecting the world. You are to prepare a PowerPoint presentation that focuses on how the water shortage is affecting the world. You will work with a partner or by yourself (no more then two people per group).
You may choose from the following topics:
1. Research how the water crisis is affecting a specific country. You can research the water use issues of that country, the quality of the water available in the country, conservation and productivity.
Some areas that are facing a shortage are:
China, India, Israel, Africa, United States, Mexico
But you may choose any country you want.
2. Research ways in which we as a world can try and make a difference on this crisis. What ways can we prevent a shortage? How can we preserve water? How can water productivity be increased?
3. Compare water issues in developed nations to underdeveloped nations. How can water rich countries help provide water resources to countries that have a water shortage?
4. Topic of your choice that deals with the world’s water crisis. See me for approval but I will be flexible with the topics.
