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.
Maine Learning Results 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.
- Weather hazards include floods, windstorms, lightning, hail and snow.
- Designs reduce harm: seawalls, strong roofs, weather alerts.
- 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
