Question:

How do the vibrations of the different sounds compare for higher vs lower pitch notes?

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- “Higher vs Lower Notes p.28” (Left Side); Head page 28 properly with “Higher vs Lower Notes- 11/28/17.”
  2. Write Pair Share– “What patterns did you notice between how the instruments & music box made different pitched sounds? Do you think there are differences in the vibrations being made as different notes are being produced? Explain.” Write the answers to the questions on ISN p.29. Pair with your cooperative table group to share your responses and come to a consensus. Share your group responses with the class.
  3. Investigation– Higher vs Lower Notes- Predict a graph of the shorter wooden stick pulled back about 10cm, then predict a graph of longer wooden stick pulled back the same amount. Use the probe to collect data & generate graphs to compare to your prediction. Record the graphs in Observations in your handout. Notice patterns between the graphs of the shorter wooden stick and the longer wooden stick. Answer Making Sense questions 5, 6, & 7 of handout.
  4. Conclusions– On ISN p.28, answer the following question: What discoveries did you make about sound sources and why different objects produce sounds of different pitches? Work in your cooperative table groups.

Question:

Are other objects that produce music also moving back and forth when they make sounds?

Learning Tasks:

  1. Do Now– Copy down today’s homework assignment in your planner. Get out your ISN and open to pages 22 and 23. Get out your Vibration Cause & Effect Model handout.
  2. Class consensus discussion/Review HW– Summarize in words what we showed in our models about vibration (movement & shape changes) of a drum. Share Vibration Cause & Effect Model on handout. Come to a consensus for what we mean when we say an object is vibrating. Add what we figured out about vibration to sound source in initial model.
  3. Scientific Language Notecard- Make a scientific Language Notecard for the key word vibration.
  4. Notebook Work– Tape Scientific Language notecard to ISN p.22. Tape Vibration Cause & Effect Model handout as flip page to ISN p.22. Tape any extra writing as flip page to ISN p.23.

Home Learning:

ISN’s are due! 🙂 Per. 6- today, Per 3 & 7- tomorrow

Wednesday, 11/1/17- A Day

Question:

Are other objects that produce music also moving back and forth when they make 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- “Instruments Investigation p.22” (Left Side); Head page 22 properly with “Instruments Investigation- 11/1/17.”
  2. Complete Investigation Observe slow motion video of instruments (guitarsnare drumtuning fork) being struck/plucked & record observations in data table.
  3. Turn & Talk/Stop & Jot: Write the answers to the following questions below the Data Table on ISN p.23: What similarities did you notice between how each of these object moved? Why do you think all these objects continued to move the way they did, even after the thing that initially pushed/pulled on them was no longer touching it?
  4. Class consensus discussion– Describe some of the shape changes & motion changes that you observed in the instruments. Come to a consensus for what we mean when we say an object is vibrating. Vibration Cause and Effect Models on handout- Construct first model together as a class, and apply the model to a guitar or a tuning fork individually.

Home Learning:

  • Complete individual model of guitar or tuning fork on handout.
  • ISN’s are due! 🙂 Per. 4- today, Per.6- tomorrow, Per 3 & 7- Fri.
