Question:

How can so many different sounds be coming from the needle and the record when you spin it?

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- “Model p.30” (Left Side); Head page 30 properly with “Model- 12/5/17.”
  2. Complete Investigations 1-3- Let’s look at the record and needle again to see if its vibrations are changing as it produces different sounds…We’ll look again at the Michael Jackson video of the closeup of the needle on the record. This time, look to see differences in the frequency or amplitude of the vibrations of the needle as it produces sound. Answer questions Q3-Q6 in handout. Look through the procedure for Investigation 2. Complete it with a partner. When you are done with Investigation 2, send one partner to the demonstration desk to get a copy of the photograph of the surface of the record. You will be able to write, label, & draw on this photograph so be prepared so share your findings.

Question:

How can so many different sounds be coming from the needle and the record when you spin it?

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- “Investigations 1-3 p.31” (Right Side); Head page 31 properly with “Invetigations- 12/4/17.”
  2. Talk with your cooperative table group– How do the vibrations from sound sources compare when they produce louder vs softer sounds? How do the vibrations from sound sources compare when they produce higher vs. lower pitch sounds? What makes the needle on the record vibrate as the record is spun?
  3. Write-Pair-Share- Individually, write your answer to the following question on ISN p.31. Use complete sentences. If differences in the volume of a sound and differences in the pitch of a sound are due to differences in the amplitude & frequency of vibrations, then wouldn’t something in the grooves of the record be making the needle vibrate at different frequencies or deform with different amplitudes so that it produced different sounds? What might be forcing it to change its pattern of vibration? Pair to share your answers with your cooperative table group and then the whole class.

Friday, 12/1/17- B Day

  1. Do Now– Copy down today’s homework assignment in your planner. Get out your ISN and open to pages 18 and 19. Work out the following problem: Mr. Golinski is always yelling and with such a deep voice. On the other hand, Mrs. Vigliotti has such a quiet, high pitched voice that she is sometimes hard to hear! How would a graph of the vibrations in Mr. Golinski’s voice box compare to a graph of Mrs. Vigliotti’s voice box?

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?
