Minds in Motion:PBL cases for a high school Physics Icurriculum Patti Lawrimore North Springs High School Dan Hruschka Emory University July 28, 2003
The Sky is Falling--Introduction • Dr. Andrea Smith, an amateur astronomer stargazing from the Mt. Haleakala Observatory notices a collection of previously unknown objects in the night sky that pose her some concern. Dr. Smith consults you, a team of experts at North Springs High School to confirm her suspicion. Measurements over the past three days in November indicate the objects are moving quickly through space, in the same plane as Earth’s orbit.
The Sky is Falling—Session 1 • Divide class into teams (5-6 students each). Introduce NEO (Near-earth object) problem and brainstorm on what formulae and data are needed to calculate whether the NEO will hit the earth. • Assignment: Provide each team with data for one of 4 objects requesting that they determine if and when their NEO will hit. • Assessment: Short quiz on NEOs and learning issues
The Sky is Falling—Session 2 • Teams return, with one team reporting that a NEO will hit the earth (and when). • U.S. president recruits students to assess possible consequences to the earth and its populations. • During last half of session, teams perform cratering experiment with BB falling into flour. • Assignment:present their assessment of possible consequences to class the following week. • Assessment: Quiz on calculation of impact of a new hypothetical NEO.
The Sky is Falling—Session 3 • Each team presents report on consequences • Teams brainstorm strategies for reducing the comet impact. • Each team is assigned a different strategy, and is told to return with report on their strategy, with special attention to its physical feasibility. • Assessment: Presentation rubric, short quiz on consequences.
The Sky is Falling—Final Session • Session 4: Teams present reports on proposed solutions. • Assessment: Proprosal rubric. Peer-assessment rubric. Longer quiz with calculation of another NEO impact and questions about NEO impacts.
