Part A -  Objectives/ Guide Questions

1. Describe the physical properties of water including solubility, boiling freezing range, ability to store heat (Specific Heat), and the expansion upon freezing. Give an example of each property as it applies to the environment.

 

2. Describe how fresh water (ground, glaciers, rivers, swamps and lakes) and salt water is distributed over the surface of the earth (by percent). (World Water Usage)

 

3. Describe at least two major water pollution problems of streams, lakes, and oceans and how can they be prevented?

a) Describe the process of eutrophication, and explain why it occurs. Apply this to what happened in Lake Eerie.

b) Describe how oxygen demanding wastes impact organisms in an aquatic ecosystem.

c) Describe the problems of thermal and sediment pollution in aquatic ecosystems and indicate at least two solutions used to solve each problems.

d) Distinguish between point source, and non-point sources of pollution. Provide examples of each.

 

4. Describe drinking water treatment in your community.

a) How drinking water is obtained from a source, treated and finally delivered into the home.

b) The three levels (primary, secondary, and advanced) of waste water (Sewage Treatment) treatment.

 

5. Describe the location of groundwater (type of ground and depth).

a) How is groundwater polluted and why it is such a serious problem?

b) Describe an aquifer, its sources of the water and pollution problems.

 

6. Describe the hydrologic/water cycle. Indicate the importance of the water cycle and how water is constantly recycled, re-purified, and reused. Indicate the importance of energy in the water cycle.

 

7. Identify the causes of freshwater shortages in the U.S. and other nations. Identify three solutions and their disadvantages.

 

8. Identify the usable fresh water and the percentage used for industry, agriculture, and domestic use.

 

9.  Historically, humans have addressed water problems by obtaining more water. To what degree is this not a viable option for the future?

a) How can demand be reduced in agriculture, industry, and domestic use?

b) How can we use water more sustainable?

c) Which of the following would conserve more water: Not eating a one pound piece of grain fed beef, or not showering for six months?
