Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

The Nashua River serves as the focal point of an investigation of the treatment of and care for natural resources. A reading of A River Rand Wild: An Environmental History by Lynne Cherry, launches the study and class members consider...

Is there a correlation between a country's wealth and the extent of its ecological footprint? What exactly constitutes an ecological footprint, and how does one country stack up against the rest? This is a unique lesson to incorporate...

Here is a lesson that walks youth through an online carbon footprint calculator produced by the University of California, Berkeley. Once learners finish inputting information, they compete a worksheet with the results. This is simple,...

Wind turbines, daylight savings time, noise pollution, social problems. To develop close reading skills, high schoolers examine pairs of articles presenting opposing viewpoints of the same topics and respond to questions that...

New roads, new businesses, new developments, new mass transit systems. All growth has both positive and negative effects on communities. Government classes investigate the principles of Maryland's 1997 Smart Growth program and...

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

During a cholera outbreak, scientists presented two theories; one theory was based on miasma and the other on germs and contaminated water. The lesson looks at the scientific process for finding the real culprit. 

Sediment samples from the ocean bottoms tell scientists about climate change, pollution, and changes in erosion for the area. Groups of learners focus on sediments and their movement through water. During a hands-on activity, they...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Pregnant women exposed to PAH air pollution increase the risk of obesity in their children. The example of epigenetics, along with others, builds the basis for understanding the process of cell differentiation. Scholars view a video,...

Clear water does not mean clean water. A collaborative lesson has groups play a board game to identify sources of water pollution and develop strategies for improving water quality. Their investigations include reference to the water...

For every action there is a consequence. Scholars continue their work on creating a cascading consequence chart about DDT using Welcome Back, The Exterminator, Rachel Carson: Sounding the Alarm on Pollution along...

Get kids interested in stargazing with a step-by-step guide. The guide begins with the do's and don'ts, what the defines a star, and introduces a journal. The page is linked to see stars if light pollution keeps stars away in your area.

Fourth and fifth graders take a close look at oil spills and the devastating effects they have on the environment. They explore the various methods for cleaning up oils spills and perform and hands-on simulation of an oil spill in class....

Students discover what a watershed is and which one they live in. Using the internet, they research why watersheds are important to an ecosystem and how to keep them from getting polluted. They use a map to locate various items within a...

Middle schoolers explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth...

Students explore environmental care by participating in an Earth science activity. In this clean water lesson, students discuss what a watershed is, how they become polluted, and how it affects the overall quality of drinking water....

Students investigate caffeine as a potential new pollutant in a northwest river system. Effects of caffeine on invertebrates and salmon fry will be explored through field work and lab work.

Students study the earth as a system, and the fragility of that system when population, and pollution, are considered as interactive parts of earth.

In a series of lessons, examine the impact on humans by microcosms in the biosphere. Among the plans structured for students with different abilities and learning styles, are activities describing the symbiotic relationship, drawing the...

Learners play a game in physical education class to examine how a deer survives. Using nature as a guide, they discover how it is constantly changing due to weather, food, water, pollution and predators. They discuss the characteristics...

Evaluate the effectiveness of Kyoto Protocol in addressing the issue of global warming. In this global warming lesson, learners compare the pros and cons of the cap-and-trade system versus a carbon tax, as well as other possible...
