Pollution PurgeChemical Reactions & System DesignGrades 9-12
Storyline
Phenomenon
A series of chemical leaks threatens to contaminate local water systems. Students must determine how chemical properties influence solubility, toxicity, and reactivity as they decide on clean-up strategies.
Science and Engineering Practices
Asking Questions and Defining Problems
Identify factors contributing to chemical runoff and water contamination.
Analyzing and Interpreting Data
Evaluate provided chemical property tables, concentration data, and pH readings.
Constructing Explanations and Designing Solutions
Propose clean-up methods based on the chemistry of solubility and reaction rates.
Engaging in Argument from Evidence
Defend chosen solutions using evidence from data.
Crosscutting Concepts
Systems and System Models
Recognize how contaminants move and react within interconnected environmental systems.
Cause and Effect
Connect chemical structure and properties to observable reactions in the environment.
Disciplinary Core Ideas
PS1.A: Structure and Properties of Matter
Properties of substances explain their behavior in environmental systems.
ESS3.C: Human Impacts on Earth Systems
Human activity can alter natural chemical cycles and water quality.
