DO NOW 1. What type of pollution is caused by fertilizers? 2. What is it called when rows in a field are plowed in curves instead of straight lines? 3. What are the tiny particles and gases carried into the air that cause pollution ? 4. What is it called when a steep field is changed to a series of smaller fields? 5. What type of pollution is caused by cars?

Key Questions What is the ozone? How does the ozone get holes in it? Where do chloroflurocarbons come from? What does UV radiation cause? What is water conservation? What is air conservation? EQ- What is the ozone and how does it get holes in it?

1. What is the ozone? Ozone-forces that protect life on Earth from solar radiation.

2. How does the ozone get holes in it? The holes in the ozone come from chlorofluorocarbons also called CFCs.

3. Where do chlorofluorocarbons come from? CFCs come from aerosol cans, cooling AC systems, refrigerator systems.

4. What Does UV radiation cause? Ultraviolet radiation causes skin cancer and damaging effects of plants and animals.

5. What is water conservation? Water Conservation Use water saving faucets, shower heads, and toilets Turn off water when brushing teeth Only wash full loads in dishwasher Water sewage treatment plants Prevent factories from dumping chemicals Prevention of fertilizer runoff

6. What is air conservation? Air Conservation Filters on smokestacks at factories (filters out harmful chemicals) Devices on car exhaust Part of a smokestack filter.
