A Carolina Exclusive! Grades 9-12. Students explore the need for laws to protect our environment and standard of living. These inquiries emphasize the importance of the Clean Air and Clean Water Acts, as well as the concept of the Tragedy of the Commons, as students investigate each issue and its impact on the environment. 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. Kit includes lab supplies (enough for 30 students working in groups) plus teacher's manual. Kit Refill replenishes all perishable materials; price includes shipping and handling. Note: Order the kit refill with the perishable materials included or with a voucher to request the perishables later at your convenience. Contact us or return the voucher at least 2 weeks prior to requested delivery date to ensure prompt arrival of materials. Multi Class Equipment Set provides additional lab supplies so you can use the kit in 1 additional class section per day.

Note: Order an extra kit refill for each additional class section. For example, to teach the kit in 3 environmental science sections on the same day, purchase 1 kit, 2 kit refills, and 2 multi class equipment sets. Part of the Inquiries in Science® series.
