Activity Station #1
1. What type of sound did you produce? What
did it sound like?
2. Which glass had the highest pitch sound? Did it have more or less water?
3. What do you believe caused the sound, the water, the air, or the glass?
4. Were you able to set up a musical scale? If so, how did the amount of water and pitch compare?
Activity Station #2
1. Why do you cut and pinch the straw? (Hint:
think of a clarinet and how it works.)
2. Write a hypothesis concerning the length of the vibrating air column and the pitch that you hear.
3. What is the relationship between the length of the straw and the sound produced? Was your hypothesis correct or incorrect?
4. How can the length of the vibrating air column be changed on a musical instrument without cutting it?
Activity Station #3
1. What was the relative loudness of the
tuning fork, was it loud or could you barely hear it?
2. Using the stopwatch, how long does it take for the sound to die out so you can no longer hear the tuning fork?
3. What is the relative loudness now, was it loud or could you barely hear it?
4. Using the stopwatch, how long does it take for the sound to die out so you can no longer hear the tuning fork?
5. Which tuning fork spilled the most water? WHY?!
Activity Station #4
1. How is sound transferred from one cup
to the other?
2. What is the medium that it is being transferred in?
3. Sound waves are what type of wave?
4. Why did the sound transmit better with the special "telephone?"
Activity Station #5
1. What will happen if you strike the bottle
with a metal spoon?
2. What vibrated to make the sound you heard?
3. Where did you hit the jar to give the best sound?
4. Write a hypothesis concerning which bottle will have a higher pitch and which will have a lower pitch.
5. Was your hypothesis correct? Which bottle had the highest and which had the lowest?
Activity Station #6
1. What did it sound like? What type of
sound did it make?
2. Did the sound change when you increased the speed? What did it sound like?
3. Did changing the direction change the
4. Did changing the direction of the tube change the sound?
5. Write a statement explaining how best to get sound from the tubes.
Activity Station #7
1. What does the wave look like?
2. What does this wave look like?
3. How does the volume effect the appearance of the wave? Make a statement about pitch and volume to wave appearance.
