Students Will Review:
This chapter helps students review the concepts in an environmental concerns unit of a standard middle school life science course. Topics covered include:
- Sources of air and water pollution
- Atmospheric causes of global warming
- Effects of a thinning ozone layer
- Groundwater use issues
- Water treatment techniques
- Water quality laws
1. Pollution: Physical, Chemical & Biological
Pollution is the presence of unwanted substances in an environment. It is often the result of human interference. Learn about physical, chemical and biological pollutants and see examples of each.
2. What Is Air Pollution? - Definition, Sources & Types
In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.
3. Global Warming: Atmospheric Causes and Effect on Climate
Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.
4. The Ozone Layer: Importance and the Harmful Effects of Thinning
In this lesson, you will learn the importance of the ozone layer and how it is depleted. You will also study the research and policy that has been instrumental in its recovery.
5. Water Pollution: Definition, Types, and Sources
In this lesson, you will learn about the different types and sources of water pollution. You will gain an understanding of both surface water and groundwater pollution and the similarities and differences between them.
6. Environmental Problems Associated With Groundwater
Groundwater is an important natural resource, but like many of our other resources, it's affected by the surrounding environment and human activities. In this video lesson, you'll learn about some of the environmental problems associated with groundwater and why groundwater is especially vulnerable to them.
7. Water Treatment: Improving Water Quality
In this lesson, you will learn how water is purified for drinking, and how wastewater is treated before being put back into the environment. You will also learn about water purification issues in developing countries.
8. The Clean Water Act & Safe Drinking Water Act: Legislation for Clean Water
In this lesson, you will learn about the Clean Water Act of 1972 and the Safe Drinking Water Act of 1974. You'll discover how both laws help keep our waters free of pollution and safe for everyday use.
