Natural hazards are natural events or processes that could harm people or property. Earthquake shaking can damage buildings. Floodwater can enter homes. Volcanic lava or ash can harm people. Communities plan ways to reduce these impacts. Earthquake-resistant design can reduce building damage from shaking, but damage is still possible. Flood barriers can hold back some water, but water may flow over or around them. Near a volcano, warning messages and practiced evacuation routes can help people leave when officials order it. Warnings do not promise enough time to leave. Plans may combine different solutions. *(drawing: Suggest several ideas before choosing a plan. Different ideas may serve different safety goals.)* Generate ideas by naming the harm. Ask how to protect buildings or help people prepare or leave. Suggest two different ways and explain how each helps. Compare effectiveness: how well each meets the goal. Cost means money needed; taller cost bars mean higher costs. Feasibility means having enough time, workers, and materials. Check all limits, including budget and deadline. Cheap plans may miss the goal. **Example.** In a made-up flood test, design A keeps 3 model homes dry and costs $400. Design B keeps 7 dry and costs $700. Both can be ready in 2 weeks. A town needs at least 5 homes dry, a cost of at most $800, and completion within 3 weeks. B meets all three limits. A is cheaper but misses the goal. Model results do not promise the same protection in a real flood. When a plan uses two solutions, add their separate prices to find the total cost. In a made-up plan, barriers cost $400 and warning messages cost $200. Together: $400 + $200 = $600. A barrier can hold back water; messages can help people prepare or leave. Never enter floodwater to protect belongings. Follow local safety instructions. **Recap.** Compare solutions by asking how well they work, how much they cost, and whether they are realistic to build. *The lesson, questions and flashcards were written for this dataset.
