How do the vibrations of the sound source compare for louder vs softer sounds?
- Do Now– Get out the handout “Lesson 5: How do the vibrations of the sound source compare for louder vs softer sounds?” Open the handout to page 3. Share your answers to the conclusions questions. Each cooperative table group should be prepared with: 1. the most important thing learned from the graphs about vibrations for loud & soft sounds and 2. questions/new ideas to investigate.
- Scientists’ Circle– Continue to point out features/patterns from observations of graphs for both conditions. Describe Characteristics of Waves. What did we learn about the sound source in our model for the record sound device phenomenon? What are our next steps?
- Scientific Language Notecards– Make a Scientific Language Notecard for the key words wave, amplitude, & frequency. Tape Scientific Language Notecards to ISN p.27. Enter the key words in the Index.
