Question:

How do the vibrations of the sound source compare for louder vs softer sounds?

Learning Tasks:

  1. 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.
  2. 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?
  3. 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.

Question:

How do the vibrations of the sound source compare for louder vs softer sounds?

Learning Tasks:

  1. Do Now- Copy down today’s homework assignment in your planner. Get out your ISN and add to the Table of Contents- “Loud vs Soft Sound p.26” (Left Side); Head page 26 properly with “Loud vs Soft Sound- 11/20/17.”
  2. Investigation– Loud vs Soft Sound- Predict a graph of the wooden rod pulled back a small amount (representing soft sound), then pulled back farther (representing loud sound). Use the probe to collect data & generate graphs to compare to your prediction. Notice patterns between the graph of the wooden rod pulled softly vs harder. Answer Predict, Observations, & Making Sense questions on pages 2-3 of handout.

Question:

How do the vibrations of the sound source compare for louder vs softer sounds?

Learning Tasks:

  1. Do Now– Get out your ISN and add to the Table of Contents- “Loud vs Soft Sound p.27” (Right Side); Head page 27 properly with “Loud vs Soft Sound- 11/17/17.”
  2. Science FridayBeauty Beyond Skin Deep
  3. Investigation– Loud vs Soft Sound- In your cooperative table group, answer the “Planning Our Investigation” questions. Then use the range finder probe to detect distance from a student volunteer to the probe over time, moving closer to and farther from the probe and at different speeds. Describe how the graph changes. Observe an object, the wooden stick, at rest. Describe the shape of that graph. Answer the questions on page 1 of handout.

Question:

Do all objects vibrate when they are making sounds?

Learning Tasks:

  1. Do Now– Get out your ISN and open to page 24. Read your conclusion on page 24 to your group. What do all of the conclusions have in common? What is something different about one person’s conclusion?
  2. Scientific Language Notecards– Make a scientific Language Notecard for the key word elasticity. Tape Scientific Language notecard to ISN p.25. Enter the vocabulary word Elasticity p.25 to the E Section of your Index.
  3. Conclusion– Switch ISN’s around the table. Read each other’s conclusion on ISN p.24, looking for the six elements on the board. Place a sticky note on the conclusion with the elements that are missing.
  4. Driving Question Summary Table- Complete the Summary Table on pages 18-19 for the Instruments Investigation on pages 24-25.
