School / Organization, City and State / Province
Belmont University, Nashville, TN

Grade Level
9th grade

Standards Met
Frameworks PS2.C: Stability and instability in systems (5th through 12th)
Frameworks PS4.A: Properties of waves—Amplitude (by end of grade 8)
Frameworks Practice 4: Graphing

Time Needed
45 minutes

Objective(s)

  • What is an oscillation?
  • How does an oscillation in Portal 2 compare to oscillations in the real world?
  • How can you measure and graph an oscillation?

Summary
Students see that they can create an oscillation by passing through two portals themselves or by dropping a cube through two side-by-side portals. They observe what happens and discover that they can measure the period of the oscillation and graph its motion.

Vocabulary
Oscillating, Oscillator, Oscillation, Friction, Period

Student Prerequisites
Experience with a stopwatch and graphing; familiarity with the term friction

Teacher Materials Needed
None.

Student Materials Needed
A stopwatch, Graph paper
