Staying Safe from Nature

Aligned to 4-ESS3-2 — Next Generation Science Standards.

What this lesson teaches

Natural events like floods, earthquakes, and wildfires can harm people and buildings. Engineers design solutions, such as walls, warning systems, and stronger buildings, to reduce the damage these events cause.

Worked example

A town near a river builds a tall wall called a levee. When heavy rain makes the river rise, the levee holds the water back and keeps homes from flooding.

Practice questions

  1. Think of a natural event that can happen where you live. What damage could it cause?
  2. Design a barrier or a plan that could protect a house from one natural hazard.
  3. Compare two solutions for the same hazard and tell which one protects more people.

Protegernos de la naturaleza

Los eventos naturales como las inundaciones, los terremotos y los incendios forestales pueden dañar a las personas y a los edificios. Los ingenieros diseñan soluciones, como muros, sistemas de alerta y edificios más resistentes, para reducir los daños que causan estos eventos.

Ejemplo: Un pueblo cerca de un río construye un muro alto llamado dique. Cuando la lluvia fuerte hace crecer el río, el dique detiene el agua y evita que las casas se inunden.
