Product Details

Challenge your students to understand the potential harm that lead presents to their lives and the environment. Lead is a naturally occurring stable element that accumulates in soil and water, as well as in the tissues of the plants and animals that grow in contaminated areas. In this hands-on lab activity, students discover how natural and industrial processes ultimately affect human health by testing simulated environmental water samples for the presence of lead. The results illustrate a toxic variation of a nutrient cycle. The cycling of environmental pollutants in the biosphere is a new and important concept for students who are growing up in an eco-conscious society. Complete for 30 students working individually. Super Value Kit is complete for 5 classes of 30 students working individually. A 0.1-g precision balance and other common laboratory supplies are required but not provided.

Performance Expectations

MS-LS2-3: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
MS-ESS3-3: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
HS-LS2-4: Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
HS-LS2-7: Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
HS-ESS3-4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.
