- Perform an LD50 experiment
- Simulate the effects of smog on plants
- Demonstrate the need for environmental regulation
Grades 9–12. Students explore the need for laws to protect our environment and standard of living. Inquiries emphasize the importance of the Clean Air and Clean Water Acts, as well as the concept of the Tragedy of the Commons. They perform an LD50 (lethal dose, 50%) experiment of a water pollutant on a population of brine shrimp and investigate the effects of nitrogen dioxide on plants.
