Product Details

The soil in and around the Walker quarry has become contaminated! It is up to your students—as forensic scientists—to perform tests and use problem-solving skills to determine who is responsible for the contamination. Students will perform chlorine, iron and pH tests on samples from various locations of the quarry to solve the mystery. A fun activity that will surely peak your students’ interest. Kit includes all materials to perform the activity, easy-to-follow procedure and multiple scenarios to select from.

Complete for 30 students working in pairs.

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-LS2-1. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in 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-ESS3-4. Construct an argument supported by evidence for how increases in human population and percapita consumption of natural resources impact Earth’s systems.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-LS2-1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
HS-LS2-6. Evaluate claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
HS-ESS3-6. Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.
