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-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
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-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-ESS3-1. Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity.
HS-ESS3-2. Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios.
