Focus Question:
How do the vibrations from a sound source compare for higher-pitch versus lower-pitch sounds?
Learning Tasks:
- Do Now– Please get out your ISN. Add to the Table of Contents: “Frequency & Pitch p.75” (Right Side). Head p.75 properly with “Frequency & Pitch -3/5/2020.”
- Discussion About Frequency & Pitch/Notes– On ISN p.75, record notes on the discussion about frequency & pitch. Apply ideas about frequency, pitch, and amplitude to the question: How might you explain how the speaker in the truck can make so many different sounds (loud, soft, high pitch, and low pitch)?
- Driving Question Summary Table (DQST)– Update the DQST on ISN p.62-63 (or 64-65) for the “Motion Detector 2” investigation on ISN pgs. 72-73.
- Practice– “Analyzing Graphs of Sound Source Vibrations” handout
