This Finding the Crater activity also includes:
A mass extinction event caused by an impact usually leaves a crater. Scholars use data from 10 different sites around the world trying to determine where to look for the crater. They use data, listing the amount of various minerals to create a map and narrow down the search.
- Update the estimated age of the mass extinction event to 66 million years ago, instead of the 65 million years ago mentioned in the lesson
- Pre-teach the common minerals found in asteroids that rarely exist on Earth
- Relies on prior knowledge of the law of superposition, longitude, latitude, geological timescale, and the Paleogene Period
- Offers ideas for using the lesson as a whole class discussion, splitting into small groups and doing stations, or assigning it to individuals
- Includes differentiation in teaching methods for middle school and high school level courses
