Question:

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

Learning Tasks:

  1. Do Now- Read This Brainteaser … bet you CAN!The phaonmneel pweor of the hmuan mnid: I cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdgnieg. Aoccdrnig to a rscheearcr at Cmagbride Uinervtisy, it deosn’t mttaer in waht oredr the ltteers of a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Amzanig huh?
  2. Snowball Discussion/Student Graph Analysis– Each problem was worked out on your own. On a long paper, do out the problem that you’ve been assigned. (Seat 1- problem 1, seat 2- problem 2, seat 3- problem 3, seat 4- problem 4) Now pair together and share your ideas/show your problem. (seat 1 and seat 2; seat 3 and seat 4). Finally, share your ideas/show your problems with the cooperative table group. (seats 1 & 2 with seats 3 & 4)

Question:

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

Learning Tasks:

  1. Do Now– Copy down homework in your planner. Get out your ISN and open to page 28. Read your conclusion to your cooperative table group. Did you agree or disagree about why different objects produce sounds of different pitches?
  2. Scientists’ Circle (Building Understandings)- Point out features and patterns from observations of graphs for both conditions. Calculate highest amplitude of waves and frequency of waves on both graphs. What do you predict would happen to the frequency of vibration waves if we made the stick shorter and struck it just as hard? What if we made the stick longer? Think back to what you know about how the needle and the record surface interact. What about that interaction might help explain how it could be producing so many different sounds (with different pitches and different volumes) at different points on the record?
  3. Notebook work– Tape handout as flip page to ISN p.29

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:

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.29” (Right Side); Head page 29 properly with “Higher vs Lower Notes- 11/27/17.”
  2. Turn and Talk– Summarize what our question was that we investigated last week. Then brainstorm: What are some musical instruments that we can look at more closely so see how they make different pitch sounds?
  3. Investigation- Set up data table on ISN p.29. Make observations of plucking a guitar string at different lengths, striking different bars on a xylophone, and the structures of a music box device when the handle is cranked. For each, pay attention to anything you notice about the structure of the instruments as they play different notes. Record your observations in the data table.
  4. 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.

Thanksgiving Science!

  1. Do Now– Ask the person who sits next to you if he or she will eat turkey tomorrow. If not, what will be eaten instead? Also find out if he or she prefers apple pie or pumpkin pie or no pie at all. Get out your ISN and open it to p.26
  2. Notebook work- Cut the conclusion from the packet and tape it to ISN p.26. Tape the rest of the handout onto ISN p.27.
