Learn how the Mars Rover prevents germs from going to and coming from Mars in this video tutorial.

Directions for doing a simple simulation that shows how pollution spreads through groundwater sources.

The global impact of decades of environmental pollution is described and the implications this has for the future survival of life on our planet. (Updated: January 26, 2012)

Find out about some of the most prevalent pollutants in water, and learn about the effect they have.

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead...

Students can learn all about water pathogens in this online exhibit. They'll explore what kinds of micro-organisms infect water, how a water supply can get contaminated, how it is protected, and how officials investigate cases of...

Set in the context of ground water contamination in Bangladesh, this stoichiometry and analytical chemistry activity examines the issues around identifying wells contaminated with arsenic. In this activity, students perform a gravimetric...

In this What's Up In The Environment? video segment, learn how a contaminated plot of land in Philadelphia was recycled into a beautiful public park called Liberty Lands.

This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and...

Bacteria are everywhere and can cause many different kinds of diseases. Bacteria are a major source of food contamination. Students will grow bacteria collected from different places and compare the results.

Do you always wash your hands before preapring food? Simple things that can be done during food preparation reduce the risk of food contamination. In this activity students learn how to safely prepare a fun treat in class- fruit ice cream.

Listing of various fact sheets created and published through the Long Island Sound Study. Topics include How Low Dissolved Oxygen Conditions Affect Marine Life in LI, Impact of Atmospheric Nitrogen Deposition on Long Island Sound, Sound...

The Center for Science in the Public Interest offers a discussion of contaminants that can be found in tap water and chemicals added to water in the public water systems. The topics discussed are arsenic, parasites, lead, turbidity, and...

In this activity, students act as environmental engineers involved with the clean up of a toxic spill. Using bioremediation as the process, students select which bacteria they will use to eat up the pollutant spilled. Students learn how...

A hypothetical scenario is introduced in which the class is asked to apply their understanding of the forces that drive natural selection to prepare a proposal along with an environmental consulting company to help clean up an area near...

Students take advantage of the natural ability of red cabbage juice to perform as a pH indicator to test the pH of seven common household liquids. Then they evaluate the accuracy of the red cabbage indicator, by testing the pH of the...

In this unit, students explore the various roles of environmental engineers, including: environmental cleanup, water quality, groundwater resources, surface water and groundwater flow, water contamination, waste disposal and air...

Middle schoolers learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. And, they are introduced to the process of bioremediation and examples of...

Students learn the basics about soil, including its formation, characteristics and importance. They are also introduced to soil profiles and how engineers conduct site investigations to learn about soil quality for development,...

Your questions answered about environmental restoration after chemical accidents. A large section is dedicated to oil spills and how they contaminate the earth. Great information.

The Great Lakes Science Center provides research on various topics concerning the Great Lake environment such as fish advisories, contaminants, threatened species, low water levels, and sustainable development of the Lakes.
