Performance Expectations: 3-ESS3-1: "Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard.*

4-ESS3-2: Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.*

Disciplinary Core Idea: ESS3.B: A variety of hazards result from natural processes (e.g., earthquakes, tsunamis, volcanic eruptions). Humans cannot eliminate the hazards but can take steps to reduce their impacts. (4-ESS3-2)

Cross cutting concepts: Cause and Effect

• Cause and effect relationships are routinely identified, tested, and used to explain change.
