How do engineers protect people from earthquakes and floods?

For earthquakes, they use steel frames that bend, cross braces and rubber base isolators, so buildings sway instead of falling. For floods, they build levees of packed earth, stack sandbags and raise houses on stilts. One sheet has children sort these fixes by hazard.

How do warnings keep people safe?

Sea floor sensors and buoys send data by satellite to a tsunami warning center, which sends alerts to sirens and phones along the coast. At volcanoes, scientists watch for tiny earthquakes, a swelling bulge and more gas. In 1980 these signs at Mount St. Helens let officials close the area before it erupted.

Is there an answer key for each worksheet?

Yes. All 10 natural hazards sheets have an answer key, with sample answers for the questions children answer in their own words and the other answers to accept.

Written by Adi Ackerman, Head Teacher

A natural hazard is a natural event like an earthquake, flood or landslide that can harm people. These natural hazards worksheets for 4th grade show how engineers reduce the harm with solutions such as levees, sea walls and buildings that sway without breaking (NGSS 4-ESS3-2). Students read about the giant steel ball near the top of Taipei 101, the 10 mile sea wall Galveston built after the 1900 hurricane and the warnings before Mount St. Helens erupted in 1980, order how a tsunami warning reaches the beach, sort earthquake fixes from flood fixes and read one class's shake table test. Ten original sheets, each with an answer key.
