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.

Students use their knowledge of scales and areas to determine the best locations in Alabraska for the underground caverns. They cut out rectangular paper pieces to represent caverns to scale with the maps and place the cut-outs on the maps to determine feasible locations.

Students build model caverns and bury them in a tray of sand. They test the models by dropping balls onto them to simulate an asteroid hitting the Earth. By molding papier-mache or clay around balloons (to form domes), or around small cardboard boxes (to form rectangular structures), students create unique models of their cavern designs.

Students learn of the impending asteroid impact scenario, form teams and begin to study the situation in depth. A simple in-class simulation shows them the potential for destruction and disaster. They complete worksheets and look at maps to help them define and understand the problem: What is the needed cavern size and depth? What are the geographical areas and natural features? A homework measurement assignment prepares them for the next lesson/activity.
