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.
This zip file includes:
1. Teacher implementation guide and student handouts (pdf) - 10 pages long. Describes in detail suggestions for how to implement the week long lab. Includes a student research sheet, lab report guidelines, lab report rubric, and materials/purchasing information for lab supplies.
2. PowerPoint Notes (pptx) - 22 slides long. Describes the scientific method as it applies to this particular lab. Also used as a guide to the lab experience.
3. Notes for students (both pptx and pdf) - 22 slides long. Includes a sheet for students to take notes on based on the included powerpoint notes.
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.
