CHAPTER 17 WATER USE AND MANAGEMENT

Chapter Overview


Water is a vital resource that is essential to life. Where water is stored on Earth is
important to the study of AP Environmental Science. Knowing that agriculture
uses the greatest amount of water worldwide is fundamental information. Dams
provide both benefits to humans and causes problems for people as well as
ecosystems. Issues surrounding water diversion projects are very significant
ideas. Conservation is a topic that will become increasingly important to the
study of Environmental Science.

Water Diversion Activity
 In this activity, the students will be assigned a specific water diversion project.
Both the historical significance of the project along with the future implications
of the project will be investigated. The students can either make a poster or a
PowerPoint of their particular project. Students should include a cost/benefit
analysis from both an economic and environmental standpoint.

Ocean Acidification Activity complete in class Friday
Student:_________________________________________________
 

Procedure:
1. Put 50 mL of ocean water in a beaker.
2. Place a few drops of bromothymol blue into the ocean water. Record the color.
3. Use pH paper to record the initial pH of the ocean water. Create a data table for initial, middle, and final pH and color.

4. Using a straw, blow into the ocean water until the indicator changes colors. It should change two times.
5. As the color changes, record the pH at each different color.

Questions to Consider:
1. What was the initial color of the ocean water containing the indicator? What is the corresponding pH? Is that acidic, basic, or neutral?
 

2. What happened to the color as you blew through the straw?
 

3. What happened to the pH as you blew through the straw?
 

4. What is the identity of the gas being disseminated into the ocean water? 

Conclusions:
1. Why did the pH change as you blew through the straw?
 

2. What are the implications of burning fossil fuels to the pH of the oceans?Why are these ideas a problem for ocean ecosystems?
 

3. Do you see any connection(s) between global warming and this activity?
