Focus Question:

How can any object make so many different sounds?

Learning Tasks:

  1. Do Now– Please get out your ISN. Add to the Table of Contents: “Graphical Representation p.74” (Left Side). Head p.74 properly with “Graphical Representation-3/6/2020.”
  2. Science Friday- Face Time
  3. Write-Pair-Share– Answer the following question on ISN p.74- How do the vibrations from a sound source compare for higher-pitch vs lower-pitch sounds?
  4. Application/Practice– “Connecting Graphical Representations to the Sounds Made” handout- Pair works on their assigned question set then join with another pair to share claims, evidence, & reasoning for question set.

Thursday, 3/5/2020- A Day- Block Schedule Periods 2, 4, 6, & 8

Focus Question:

How do the vibrations from a sound source compare for higher-pitch versus lower-pitch sounds?

Learning Tasks:

  1. Do Now– Please get out your ISN. Add to the Table of Contents: “Frequency & Pitch p.75” (Right Side). Head p.75 properly with “Frequency & Pitch -3/5/2020.”
  2. Discussion About Frequency & Pitch/Notes– On ISN p.75, record notes on the discussion about frequency & pitch. Apply ideas about frequency, pitch, and amplitude to the question: How might you explain how the speaker in the truck can make so many different sounds (loud, soft, high pitch, and low pitch)?
  3. Driving Question Summary Table (DQST)– Update the DQST on ISN p.62-63 (or 64-65) for the “Motion Detector 2” investigation on ISN pgs. 72-73.
  4. Practice– “Analyzing Graphs of Sound Source Vibrations” handout

Tuesday, 3/3/2020- B Day

Focus Question:

How do the vibrations from a sound source compare for higher-pitch versus lower-pitch sounds?

Learning Tasks:

  1. Do Now– Please get out your ISN. Add to the Table of Contents: “Motion Detector 2 p.72” (Left Side). Head p.72 properly with “Motion Detector 2-3/3/2020.”
  2. Investigation– Predicting & Testing Sticks of Different Lengths- On the “Pitch Graphs” handout, draw what the graph would look like when the stick is at rest. Draw an arrow pointing to that line on each graph and label it “stick not moving.” Predict what the graph would look like for long stick/low pitch vs short stick/high pitch on both your Condition 1: Long stick and Condition 2: Short stick graphs using a dashed line. Label these lines “prediction” on both graphs. Then observe Test Condition 1 as we push the long stick 10 cm. After the test, draw a solid line and label it “actual.” Repeat for Test Condition 2: Short stick.
  3. Simulation– Speaker’s Motion– This simulation will graph the motion of the speaker while it’s making sounds. Observe low and high pitches. Sketch the speaker graphs on ISN p.72. Title the graph sketches for which sound is which and label the axes.
  4. Data Analysis from Speaker & Stick Data– Observe the four graphs from the speaker & stick data. On ISN p.72, write the heading “Data Analysis.” Look for similarities and differences within and among the graphs. Point out patterns & important features of the graphs. Write complete sentences starting with “What I see ….”
  5. Notebook Work– Tape the “Pitch Graphs” handout as a flip page to ISN p.72.

Friday, 2/28/2020- A Day

Focus Question:

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

Learning Tasks:

  1. Do Now– Please get out your ISN. Add to the Table of Contents: “Loud vs Soft Sounds p.70” (Left Side). Head p.70 properly with “Loud vs Soft Sounds-2/28/2020.”
  2. Science Friday– Is Pedigree What It’s Cracked Up to Be?
  3. Application– On ISN p.70, answer the following questions: How is the graph of a loud sound different from the graph of a soft sound? How is the graph of a loud sound the same as a graph of a soft sound? What causes vibrations with more amplitude and therefore louder sounds? What other ways can sounds be different? Give examples.
