Engaging in Argument from Evidence

Crosscutting Concepts

Cause and Effect

Knowledge

Students know:
  • Engineers design solutions to reduce the impact of weather related hazards.
  • Problems caused by weather related problems.
  • Humans can not eliminate natural hazards but can take steps to reduce their impacts.
  • Some design solutions are more effective than others.

Skills

Students are able to:
  • Identify impacts of a weather related hazard.
  • Identify the effects of solutions to a problem that reduces the impact of a weather related hazard.
  • Make a claim about a designed solution that reduces the impact of a weather related hazard.
  • Communicate evidence to support the claim about a designed solution that reduces the impact of a weather related hazard.

Understanding

Students understand that:
  • There are cause and effect relationships between weather-related hazards and design solutions created to reduce their impact.
  • There are benefits and risks to given solutions created when responding to the societal demand to reduce the impact of a hazard.
