Please sit in your assigned seats. Elizabeth or Kelly will take attendance. Krista or Elizabeth can get materials as needed from the supply cabinet during Block 1.
You will be focused on Activity 4 on pp 334. Each person will be given a maximum of 4 straws for this entire activity, so do not chew on them ;)
Take a look at the picture on p. 334. Write down 5 observations about how the sound is being produced in your notebook, and the differences among the musician's instruments. Discuss these as a class.
On p. 335, complete steps 1, 2, and 3. This should take about 5 or 10 minutes. Can you modify your instrument to make a recognizable tune? Take 5 or 10 minutes and give it a try. What difference do you notice between a closed tube and an open tube (your finger on the bottom vs. your finger away from the bottom of the straw)
As a class, watch the following:
AS a table, do a THOUGHT experiment for 4. and 5. on pp. 355 Use the video as your evidence. Watching the vids and discussion should take about 10 minutes.
Next, read p. 357-358 out loud with one partner. Pay careful attention to the diagrams. This should take about 10 minutes.
Make a reed instrument as shown on p. 358. Use a piece of paper and tape to make an extension tube. What is the purpose of the wider tube at the bottom?
Physics to Go p. 359
1, 2a, 2b, 6, 7 Stretch 4, and, if there is time, try #5 in the new gym (have Krista or Kelly check to see if it is empty first.)
