Students read a New York Times article as a class and discuss how groundwater near a nuclear test site may have been contaminated. They explore how groundwater contamination can spread through aquifers by participating in a simulation. Full Review »

Students discuss contamination of an aquifer. They build a model of an aquifer and contaminate it with food coloring. They "recharge" the aquifer with water flushings. They do the same for pumping out the aquifer. They compare the two methods. Full Review »

Students use different kinds of geologic information to predict the path of ground-water contamination from several toxic waste sources on the Massachusetts Military Reservation (MMR). They draw possible plume paths, and compare with contaminant traces. Full Review »

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to create, answer assigned questions, and then share their model and the results with the other members of their group.

Students observe the effect of croos contamination as they inoculate orange juice with penicillin mold from the refrigeration lab and active yeast solution from the sterilization lab. They experience a simulation of passing bacteria from hand to hand as students take the roles of restaurant workers and the food in which they come in contact. Full Review »

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 and collect data on the runoff from simulated rainfall. Students also conduct three other experiments using leachate from their landfills-How leachate contaminates groundwater, How leachate affects plants, and How leachate affects living things.

Students perform an experiment/investigative simulation regarding the movement of contaminants in groundwater. They test the pH of three water samples, and then use their reasoning skills to determine the source of an invisible contaminant in the samples. Full Review »

Students complete activities that show how aquifers are difficult to clean once they become contaminated. They discuss where the water in aquifers comes from, how it gets contaminated, and how to clean it up prior to setting up the experiment. Once the experiment is complete, they reassess their answers to these questions. Finally, they discuss whether flushing or pumping works best to clean the aquifers. Full Review »
