The standard

Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.

Next Generation Science Standards

What this standard means

Students need to name hazards from earthquakes, floods, tsunamis, and volcanoes, then design more than one way to reduce harm to people. They should compare ideas using evidence, such as cost, safety, materials, warning time, and how well the solution fits the place.

Mastery looks like a student saying, “This design is safer because…” and backing it up with data from a model, map, or test. Students often get stuck listing warnings instead of solutions, or choosing the “coolest” idea without comparing tradeoffs.

Ways to teach it

  • Build small structures from straws and tape, shake them on a tray, then revise designs to reduce collapse during an earthquake model.
  • Ask students to write which flood solution they would choose for a town by a river, using two reasons and one tradeoff.
  • Show two tsunami warning plans and have students circle the one that gives people more time to evacuate, then explain why.
  • Use a local hazard map or news article to identify one risk near your area and propose one practical protection plan.
