1. Haiti video: http://www.youtube.com/watch?v=04sXaTzGUss&feature=c hannel Haiti Article -Read article – first paragraph as a class -As usual, underline words you have learned in the class -Circle words you do not know -What is happening in the video? -How does this article provide a solution? -Is there anything we can do?

2. SWBAT evaluate human influences on water quality in North Carolina’s river basins, wetlands, and tidal environement

3. Cholera, a bacteria that thrives in feces- contaminated water, causes severe diarrhea and vomiting that can dehydrate and kill its victims in hours without treatment. The rate of severe cases, about 30 to 40 percent, is far higher in Haiti than the 25 percent in a typical outbreak because of extreme poverty, unsanitary conditions and the fact that cholera has not been there for 40 yearsdiarrheavomiting

6.  Haiti’s Cholera Epidemic  Water Quality Investigation  We all live downstream  Water Pollution Notes  Testing our Water  It’s a concern in Japan too!

7.  Can you taste the difference?  6 volunteers  Tap Water  Distilled Water  Bottled “spring” water  If you knew there was a cholera epidemic in your area, which water would you WANT to be drinking?

8. LAB NOTEBOOK TABLE OF CONTENTS Unit 6: Water, Oceans, and Shorelines (6.1) The Water Cycle 4/4/11 (6.2) Erosion and Deposition 4/5/11 (6.3) Aquifers 4/7/11 (6.4) Water Quality4/8/11

9.  You have each inherited $10 MILLION for a riverfront property!  On your sheet of paper, draw your river  Then, draw anything that you want to use your riverfront property for!  What are you passionate about? If you could build anything, what would it be?

10. 1. Why did you draw what you drew? 2. Is there anything on your property that you think may pollute the water ways? 3. What is nonpoint source pollution? 4. What is point source pollution? 5. What are some ways that humans pollute water? 6. How does pollution occur naturally?

11.  Respond to these questions in full sentences: 1. How does what happened upstream affect what happens downstream? 2. Does a small amount of litter make a big difference over time? 3. What are some things you can do now that you have seen first hand what litter can do to water? 4. How does this litter affect the water cycle?

13. What is going to eventually happen if you put a drop of food coloring on one of the tub walls?

14.  A watershed is all the land and river systems from which water drains toward a common point  You live in a watershed!

18.  Point Source: A single identifiable source of water pollution  Non-Point Source: Water pollution that comes from a variety of sources picked up by run-off moves

19. Water Pollution ChemicalsRadioactivity Thermal Pollution SedimentsSewage

21.  May be toxic  Examples: Acids, fertilizers, pesticides, gas, & oil  Results from oil spills, roadway runoff  Causes Health effects, eutrophication

22.  Solid and liquid radioactive wastes from nuclear power plants and leaks into groundwater

23.  Human activity increases water temperature  increases fish metabolism  consume more oxygen  BUT water holds less oxygen  destructive to developing eggs and young fish

24. Laughing lowers stress hormones (like cortisol, epinephrine, and adrenaline) and strengthens the immune system by releasing health- enhancing hormones.

25.  Soil run-off causes water to become cloudy, allowing less sunlight in for photosynthesis;  Waters become more shallow  Clogs fish gills

26.  Human & animal waste causes a decrease in dissolved oxygen in the water  May contain pathogens that are then passed on to humans

27.  The number one source of water pollution in NC is storm water run-off  Why is there high storm water run-off in NC?  Construction  Forestry operations  Mining operations  Crop production  Land fills  Failing septic systems  Road and parking lots

28.  Storm water carries sediments, oils, toxic residues, pesticides, fertilizers, animal waste and other pollutants  Sediments (the main pollutant) fills rivers and kill fish… what does that mean for the environment and the population?  Animal waste contains fecal coliform bacteria and possibly other pathogens

29.  YOU!  Require developments to be built away from creeks and rivers  Limit pavement in new development What can you think of?!

30.  Water should be neutral (pH of 7)  What is the pH of our water? *One of these is from the Garinger water fountains! Would you rather be drinking tap

31. Water Sample pH 1 2 3 4 5 6 7

32. 1. Name and describe 2 different types of pollution 2. What is a watershed 3. What is an example of nonpoint source pollution? 4. What is an example of point source pollution?
