Edvotek® The Dose Makes the Poison: Testing the Environmental Impacts of Pollution
Product Details & Documents
Engage students in a hands-on investigation of pollutant imapacts on organisms while exploring real-world environmental concepts.
Hands-on, dose-response toxicity modeling real-world pollution effects
- Exploration of toxicology concepts: concentration, exposure, organism response
- Student-generated data collection, graphing, and analysis
- Classroom-ready design for middle and high school use
- Builds critical thinking around environmental risk and human impact
- NGSS-aligned (HS-LS2-7, HS-ETS1-3)
Biological assays, or bioassays, are powerful tools that allow scientists to determine the effects of a given substance on living organisms. In this inquiry based lab, students plan and perform a plant bioassay to determine the environmental hazard of common point and non-point source pollutants. The results are analyzed using averages, standard deviations, and TC50 calculations, integrating STEM.
Time required is 2 hours, 15 minutes plus 1 week growing.
