Earthquakes and Volcanoes
Ask how seismographs and other instruments help scientists watch for danger.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 12
- A seismograph measures the shaking of the ground. Bigger swings in the line mean stronger shaking.
- Scientists use years of this data to find risky places. They still can't predict the exact day of an earthquake.
- Volcanoes often give signs. Small earthquakes and swelling ground can warn people to leave in time.
Georgia Standards of Excellence in Science:
- S5E1.c — Ask questions to obtain information on how technology is used to limit and/or predict the impact of constructive and destructive processes. (Clarification statement: Examples could include seismological studies, flood forecasting (GIS maps), engineering/construction methods and materials, and infrared/satellite imagery.)
