What This Standard Means
What Students Need to Do
- Students design more than one way to reduce harm from earthquakes, floods, tsunamis, or volcanic eruptions. They compare how well each solution could protect people and property.
What Mastery Looks Like
- Given a hazard and community setting, students can sketch and explain two workable solutions. They can compare the solutions using evidence and criteria such as safety, cost, materials, and reliability.
Common Misconceptions
- Students may think people can stop earthquakes, eruptions, floods, or tsunamis from happening. They may assume the strongest or most expensive design is always best. They may also confuse warning systems, which help people respond, with structures that reduce physical damage.
How to Assess It
- Exit ticket: A coastal town faces tsunami risk. Sketch two ways to protect people, then compare them using safety and cost.

Ways to Teach It
Build craft stick structures on a tray, shake the tray, record damage, and revise one design to improve stability.
Write a recommendation for a town facing floods, comparing two solutions by safety, cost, and likely effectiveness.
Sort solution cards by hazard, then rank each group from most to least effective and defend the rankings.
Study a community hazard map and create a short proposal for where shelters, barriers, or warning systems should be placed.
