DESIGN LAB: Nitrogen (1 of 4)

Unit 5: Food (biosphere and geosphere)
Lesson 15 of 24

Objective: Students will be able to 1) explain the role of recycling in biogeochemical cycles; 2) use test strips to measure levels of ammonia, nitrate, and nitrite in various aquatic environments; and 3) predict how levels of ammonia, nitrate, and nitrite will change over time.

Big Idea: A functional nitrogen cycle is an essential part of healthy agricultural systems. How might we use models to help us understand how the nitrogen cycle becomes disrupted and what might be done to prevent disruption?
