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.
