10th – 12th grade
- Frameworks PS2.C: Stability and instability in systems (5th through 12th)
- Frameworks PS4.A: Properties of waves— Amplitude (by end of grade 8)
- What is simple harmonic motion?
- Does Hooke’s law apply in Portal 2?
- How does height of a drop into a portal affect the amplitude of an oscillation?
Students learn about simple harmonic motion (SHM) and Hooke’s law. Then, they determine that the force of gravity rather than Hooke’s law better applies in explaining the SHM observed in Portal 2. Students test how height affects the amplitude of SHM in Portal 2 by creating a test chamber that allows for SHM to be set up from different heights.
