Exploring Groundwater Contamination (Kit)
Exploring Groundwater Contamination (Kit)
14906

Visualize the potential contamination of groundwater. Construct mini-groundwater simulation models showing the movement of a simulated, colored pollutant. Determine under what conditions contamination occurs from a variety of sources such as spill, farms, and buried tanks and how polluted groundwater eventually reaches the drinking water supply. In the process, students learn about the water cycle, water quality, ppm and ppb pollutant contamination, porosity of soils, and other related concepts. Grades 6-10.

Cleaning Up Oil Spills (40 Student Kit)
Cleaning Up Oil Spills (40 Student Kit)
14905

Observe the use of microbes for oil degradation. Model various spill scenarios and monitor the effectiveness of the provided freeze-dried oil-degrading microbe mixture in remediating the waste. Set up a simulated oil spill in water and treat it with the special microbial product to observe the physical changes degradation of oil film over time. Additionally, they simulate three spill scenarios on beach sand, gravel and cobbles in order to observe the difference in degradation rates. The class also explores bioremediation methods for other waste chemicals and compares their effectiveness to traditional clean-up methods. Grades 7-10.
