This bioaccumulation and biomagnification virtual lab is great for in-person or distance learning.
Takes 90 min to 3 days depending on level of student and how much of the 5E you wish to assign.
If time is pressing, Engage, Explore and Explain is sufficient with the basics of biomagnification and bioaccumulation.
Engage: An introduction to persistent organic pollutants and DDT with a video introduction about how DDT was used as a pesticide. Then, students read the abstract of a study done to determine that DDT thins egg shells of birds. Students practice determining the variables and control from the abstract.
Explore: Students use an online simulation to take data on DDT in the food chain.
Explain: Brief section where students determine what bioaccumulation and biomagnification are.
Elaborate: An video (or article option) from November 2020 about the discovery of barrels of DDT off the coast of Los Angeles.
Evaluate: CER. Note: This CER option is optional and an answer key is not provided. I often assess topics within a unit exam to save time.
