Design: weather-hazard protection

Define a design problem to reduce the impact of a specific weather hazard, explain how the hazard causes damage, and propose a solution with one named trade-off.

Engineers design real solutions to protect people and property from weather hazards, such as storm shutters for hurricane winds, fire-resistant roofing for wildfire areas, and raised foundations for flood-prone houses. A good design starts with the SPECIFIC hazard and explains exactly how it causes damage, before proposing a fix.

Naming a trade-off, meaning an honest downside like cost or appearance, is part of a complete, realistic design, not a weakness in it.

📋 For the teacher
Teach it (10–15 min):
  • Talk through a real, relevant hazard for your own home's region, wildfire defensible space is highly relevant across much of California.
  • Always identify the specific damage mechanism (how the hazard actually causes harm) before discussing any fix.
  • Discuss what protective features a house nearby might realistically already use for this hazard.
  • Ask for at least one honest trade-off for every proposed solution, not just its benefits.
Talk about it:
  • What weather hazard is most relevant to protect our own home against?
  • How exactly does that hazard cause damage?
  • What is one trade-off of the solution you designed?

Mastery looks like: They state a specific hazard and its damage mechanism, propose a matching protective design, and name at least one trade-off.

Common stumbles: Proposing a vague solution like "be careful" instead of a specific design feature, or skipping the explanation of how the hazard actually causes damage.
