Pollution is an example of a negative externality. Despite the gradual reduction in emissions from fossil fuels, many important environmental issues remain. Along with the still-high levels of air and water pollution, other issues...

In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of...

A collection of video lectures from a course that explores the physical processes the control Earth's atmosphere, ocean, and climate that is taught at Yale University. The course covers topics like clouds, rain, severe storms, regional...

Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on air and land quality issues. Air quality topics include air pollution sources, results of poor air quality...

[Free Registration/Login Required] A 2nd grade unit on how people and weather can change habitats. Topics include too much and too litter rain (flooding and drought), lightning and fire, and land, water, and air pollution. This flipchart...

A collection of fact sheets, brochures, and web pages about environmental issues. Topics include acid rain and air pollution, ecosystems, human health, waste and recycling, conservation, and water-related concepts and issues.

Looking at models and maps, learners explore different pathways and consequences of pollutant transport via the weather and water cycles. In an associated literacy activity, students develop skills of observation, recording and reporting...

This study provides an orientation to the methods that are applied to control and prevent environmental pollution. The basic principles followed for eliminating negative impacts on the quality of water, air or land are discussed.

Discover why plants are extremely important to humans. Resource provides an explanation of the important things they provide.

Define and explore the concept of environmental citizenship through a series of literacy-based multimedia, online and hands-on learning experiences. Discover how responsible citizens can help protect their local communities by...

Understand what natural resources are, and how important they are to Earth.

In this comprehensive website, students will learn about different forms of pollution, environmental impact of pollution, global warming, and things they can do to make a difference.

The ways in which an element or compound such as water moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. All of the atoms that are building blocks of living things are a...

A detailed overview of the greenhouse effect, with explanations about Earth's atmosphere gases referred to as greenhouse gases, and the factors that influence the heat-trapping ability of a greenhouse. All information is reinforced...

Landfills are growing at exponential rates, air and water are filled with pollution, and many are trying to find ways to manage waste better to protect the land we live off. Take a look at this resource which explains and illustrates...

Students use a pH sensor to measure the pH level of water in a stream or lake. They examine how air pollutants like sulphur dioxide, nitrogen oxides, and carbon dioxide cause acid rain, which affects the pH of water bodies and aquatic...

Lists landfill issues such as leakage, water contamination, air emissions, and hazardous waste dumping. Gives extensive documentation site links.
