Weather Hazards & Solutions

Designs that lessen the harm from floods, wind and storms.

What your child practices

Practices judging design solutions that reduce harm from weather hazards like floods, windstorms, lightning and snow, and solutions to problems when habitats change.

Alaska content standards learning standard: 3-ESS3-1; 3-LS4-4 · comparing solutions that reduce the impacts of weather hazards and environmental change

How we explain it

Children can open this short lesson before they practice.

  1. Weather hazards include floods, windstorms, lightning, hail and snow.
  2. Designs reduce harm: seawalls, strong roofs, weather alerts.
  3. Engineers test designs to see if they work.

Example: Which design best stops a beach from washing away? Waves wear away the sand. A strong wall blocks the waves. Answer: a seawall

Weather Hazards & Solutions in Alaska

In the Alaska content standards, this is unit 7 of 8 in 3rd grade Science, after Surviving in a Habitat and before Magnet Inventions.

Gradelings describes a child's practice on this unit as Beginning, Approaching, Meeting or Exceeding (Four practice steps). That reflects practice, not a report-card mark: the teacher decides the mark.
