When the ground shakes, which buildings stay up? Phil engineers structures to survive an earthquake.

  1. What happens to a tall, narrow tower when it shakes?
  2. What design changes helped a building stay standing?
  3. How do the forces of shaking try to knock a structure down?
  4. If you built an earthquake-proof tower, what would you add?

Quick work-a-long

Vocabulary: earthquake, structure, force, stable, design.

Try it: Build a small tower of blocks on a tray, then gently shake the tray. Rebuild it wider at the base and tell which version lasted longer.
