This lab experience is a great review of the scientific method as well as an introduction to the idea of environmental pollutants and their effects on organisms. This lab focuses on the organism, Daphnia magna (or just Daphnia for short), a "water flea" that is sensitive to pollutants.
The lab allows for students to self-design a lab (guided inquiry) based on a specific pollutant.

I did this lab with high school students at an alternative high school (students with behavioral and drug/alcohol issues). They were very engaged in the lab and really enjoyed it. I would recommend this lab for older elementary students (who need a challenge), middle school life science students, or high school biology/environmental students.
