Air pollution
Lesson Outline
From a photograph of a highly air polluted city, outline and discuss possible causes of this pollution.
Relate the 1998 winter olympics in Negano, Japan. This was a city with high air pollution.
Elicit ways in which the pollution affected the athletes, include asthma development, shortness of breath, visual problems, allergies, and toxicity to chemicals.
Discuss how the pollution originated and why the presence of the olympic city increased the air toxicity.
List what "good" air should contain, and discuss if the IOC should screen the cities better before awarding.

Lesson Topic
Renewable energy sources
Lesson Outline
Elicit a listing of possible renewable energy sources. Include solar, wind, and water.
Discuss the use of wind turbines, as a modern method to produce electricity.
Show that wind as been used for hundreds of years, in the form of windmills, to power equipment.
Indicate that in certain states, like Florida, solar power can be most advantageous to produce both electrical power on a grand scale, and to heat water on an individual scale.
Read and discuss from Silent Spring the beginning of the chapter which deals with the human price being paid from the use of pesticides.

Lesson Topic
hazardous waste
Lesson Outline
Elicit a workable definition of hazardous waste as waste which will cause a risk to human health.
Expand on the 3 types of hazardous waste; solid, liquid, and gaseous.
Explain how they can be toxic, corrosive, and explosive in all 3 states.
Compile a list of hazardous waste and the warning labels to be aware of.
Discuss the toxicity of heavy metals like lead, mercury, and zinc.
Discuss that the lack of properly discarding the waste can and will leak into the air and groundwater.

Lesson Topic
landfills, plastics, leaching
Lesson Outline
View and discuss a video which concentrates on the production of a landfill, what it is designed to do, and the category of waste material placed into it. Discuss alternate methods for dealing with the non decomposable waste.
The plastic problem is examined through the use of a second video. Discussion revolves around the formation of micro-plastics from the physical breaking apart of bottles, and the harm it can cause to marine life.
The formation of methane gas, how to collect it from the landfills and deliver the gas for commercial use. The leachate water which is produced when the waste is compacted must be removed before it enters the ground and pollutes the water. This water can be treated and used to water fields and plants, but it is not potable.
