Through 10 lessons and more than 20 hands-on activities, students are introduced to the concept of an environment and the many interactions within it. As they learn about natural and human-made environments, as well as renewable and...

An interactive worksheet and notes that look at the water cycle, domestic water supply, sewage disposal, water pollution, and air pollution. Useful for student review of material.

In this study, students will use lichens and tardigrades (water bears) to investigate their use as bioindicators of key air pollutants.

A collection of video lectures from a fundamentals of environmental pollution and control course taught at the National Programme on Technology Enhanced Learning. The course teaches water pollutants, waste water treatment, soil acidity,...

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...

This article is an in-depth description of the first Earth Day, and includes the impact the demonstration had on the environmental movement.

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...

Young scholars 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...

This lesson plan is designed to teach young children identify the types of pollution, the sources of the pollution, and how they can protect the environment from further pollutants.
