# Curricular Unit: Asteroid Impact

### Summary

Through this earth science curricular unit, student teams are presented with the scenario that an asteroid will impact the Earth. In response, their challenge is to design the location and size of underground caverns to shelter the people from an uninhabitable Earth for one year. Driven by this adventure scenario, student teams 1) explore general and geological maps of their fictional state called Alabraska, 2) determine the area of their classroom to help determine the necessary cavern size, 3) learn about map scales, 4) test rocks, 5) identify important and not-so-important rock properties for underground caverns, and 6) choose a final location and size.

### Engineering Connection

The Asteroid Impact unit provides a project framework in which student groups act as engineering teams to design underground caverns, following the steps of the engineering design process. Real-world engineers work in teams to invent and develop solutions to problems. Using the engineering design process, they first identify and define the problem or challenge. They gather pertinent information and conduct research to learn about topics related to the problem, and they brainstorm and propose multiple potential solutions. Engineers then evaluate the various possible solutions and select one that best meets the criteria for success. Testing is often used to verify that the proposed solution will solve the problem or challenge.
