# Tuesday, 3/3/2020- B Day

Focus Question:

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

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.

# Thursday, 2/27/2020- B Day- Block Schedule- Periods 2, 4, 6, & 8

Focus Question:

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

2. Data Analysis from Speaker & Stick Data– Observe the four graphs from the speaker & stick data. On ISN p.68, write the heading “Data Analysis.” Record the patterns that you see. Look for similarities and differences within and among the graphs. Write complete sentences starting with “I notice…” Point out the important features of the graphs.
3. Discussion About Amplitude & Frequency/Characteristics of Waves Notes– On ISN p.71, write the definitions for amplitude & frequency. Connect a greater amplitude to a louder sound.
4. Driving Question Summary Table (DQST)– Update the DQST on ISN p.62-63 (or 64-65) for the “Motion Detector” investigation on ISN pgs. 68-69.

# Thursday, 2/6/2020- A Day- Block Schedule

Focus Question:

What is happening when speakers and other music makers make a sound?

2. Observe slow-motion video of instruments and speaker– Set up a T-chart on a flip page to ISN p.59 with a column for “Slow Motion Videos” and a column for “Observations.” Record your observations of the slow-motion videos of the speaker, guitar, drum, and tuning fork.
3. Analyzing our instrument data/Building Understandings Discussion– Use the observations that you made to answer the following questions on ISN p.58: What patterns or similarities did you notice in how the different objects you observed moved while making sounds? What patterns did you notice among the instruments and the speaker? Use the questions in the Building Understandings Discussion handout to describe patterns that you noticed in your observations. Tape the handout as a flip page to ISN p.58.
4. Work on completing Sound Waves Unit Phenomenon Routine Checklist Google Slides (#011) and/or the States of Matter Changes HyperDoc (#010)
