A Mock Town Meeting on a Proposed Tank Farm
Intended as a follow up to the Protecting Your Drinking Water activity, young environmentalists use their assessment of the a hypothetical town's water supply to debate the installation of underground chemical storage tanks. With the...
Curated OER
Get to the Point!
High schoolers write out sources of pollution and identify contaminants are most likely found in urban runoff. In this pollution lesson students compare toxicity tests and chemical analysis of potential contaminants.
Curated OER
Water Contamination Demonstration
Students discuss water pollution and the Safe Drinking Water Act of 1974 after watching a teacher demonstration in which different contaminants are added to tap water. While some contaminants are not harmful to the body, in excess they...
Curated OER
Where's the Point?
Learners examine runoff for the causes, the impact, and the solution. In this investigative lesson students construct a three dimensional model of a watershed and provide information of contaminated runoff to their audience.
Curated OER
Storm Drain Dumping
Young scholars conduct an experiment to show how water gets contaminated through neighborhood runoffs.
Curated OER
Subsurface Contamination of Groundwater
High schoolers watch a demonstration with a balloon filled with water being buried in a milk container that has been cut length wise and filled with sand. Students are told that there is an underground storage tank filled with a...
Curated OER
Lead Contamination In Our Environment
Students identify the sources of lead in their local community and how to prevent further contamination. As a class, they watch a video about the effects of lead on the body and use the internet to discover any new technology that can...
Curated OER
Arsenic Contamination: Natural Disaster or Human Induced?
High schoolers list as a class the sources of arsenic contamination of water. They describe the major health effects of arsenic contamination in a letter. Students identify the regions that are affected by it.
Curated OER
Landfills and the Potential for Groundwater Contamination
Students examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill Model...
University of Waikato
Groundwater Contamination
Scientists study how pollution occurs in hopes of minimizing its effects. A quick activity shows how point and non-point source pollution enters groundwater and aquifers. Learners mimic the phenomenon with models that show how rain...
Curated OER
Testing Bangladesh's Waters
Students assess the causes and effects of massive arsenic contamination in the water supplies of 43 of Bangladesh's 64 districts. They evaluate why this contamination occurred, and how it affects the population of Bangladesh.
Curated OER
One Part A Mini Lab: Water Contamination
Young scholars investigate the effects of ground water contamination. In this ground water contamination lesson plan, students create a mini well and simulate ground water flow through the well with a contaminate (food coloring). They...
Curated OER
9-12: The Movie, "A Civil Action," as a Legal/Environmental Science Case Study
Students analyze information to determine how they can help a community that has been affected by water contamination. In this environmental science lesson, students watch portions of the movie "A Civil Action" and discuss specific...
Curated OER
Debate: "Indoor Air vs. Outdoor Air Pollution: Which Is the More Serious Threat to Public Health?"
Students work in teams to synthesize their air, asthma, air contamination, and environmental health knowledge as well as additional research to represent a particular point of view persuasively. They create a handout and presentatin...
Curated OER
What are the Ethical Considerations of Radon?
In this radon contamination worksheet, students explore the legal and ethical issues associated with radon found in indoor air of homes. Students construct a set of laws that promote fairness to all sellers, buyers and real estate agents...
Curated OER
Contaminated Drinking Water
Learners see if they can tell if our water is safe to drink by looking at it and tasting it. They perform an experiment using salt and vinegar to see when they can tell water has been contaminated.
Curated OER
Groundwater Contamination
Students study the effects of leaking tanks and their contaminants on groundwater resources. They read articles and answer related questions.
Curated OER
The Case of the Contaminated Maize
Environmental health pupils read about an outbreak of aflatoxin poisoning with the intent to examine the stages of an epidemiologic investigation. As they read the case study, they identify where the outbreak occurred, form a hypothesis,...
Curated OER
Viruses
A fliud exchange activity using pipettes/droppers to exchange fluids with at least 3 people. your learners are advised not to spill any liquid. Droppers are collected in a large beaker, and students return to desks while holding tubes....
Curated OER
Fruitvale Extension
Students determine sources and extent of ground water contaminate, apply mathematics to model in real world simulation, and use technology to present results.
Curated OER
Contaminated Drinking Water
Students discover whether their senses can detect unsafe drinking water. In the water activity lesson, students follow procedures to determine whether their bodies can detect contaminated water.
