Texas is approximately 900

miles (1.45 x 106 m) across.

Students are given an approxi-

mate value for density of rock,

rho; 3000 kg/m3; therefore,

they can calculate the mass of

the asteroid by approximating

its geometry to be spherical.

Our class uses a textbook in

In addition, two other types of assignments fol- low in-class showings of brief film excerpts. Students either 1) discuss examples of correct and incorrect physics as presented in the scene, or 2) make calcula- tions using the filmrsquo;s“data”to determine whether or not the physical quantity involved is reasonable. An example of the second activity was developed from the movie“Armageddon”7 for the Physics I: Mechanics recitation.

“Armageddon” Activity

For this 50-minute, group-work assignment, stu- dents are first given a brief background on the moviersquo;s plot:

In the movie“Armageddon,”NASA realizes Earth has 18 days before it is destroyed by im- pact with an asteroid the size ofTexas. Their solution is to land a team of oil drillers and astronauts on the asteroid, drop a nuclear war- head into its core, and split the asteroid into two pieces that will safely pass by the Earth. This must happen before“zero barrier,”four hours before imp
