Dr. Hall has a 100 ml beaker (beaker A) with 50 ml of water in it and another 100 ml beaker (beaker B) with 75 ml of water in it. When she strikes each of them with the same force, which beaker produces the loudest sound?
Beaker A
Beaker B
They sounds have the same volume
Ms Herrin strikes a 200 ml beaker containing 100 ml of water, making a sound of 500Hz. How can she make a sound of 800 Hz?
Add more water to the beaker and strike it again.
Pour out some of the water and strike it again
Strike it again with more force
Strike it again with less force
Three old fashioned telephones were made using different materials to connect the paper cups. The densities of those materials are shown below
Which substance will transmit the sound the fastest between the paper cups?
A
B
C
Mr. Biengessner was so impressed with straw whistle activity he decided to combine the straws to make a pan flute:
He blew on the red straw to make a sound. What would he have to do in order to make a sound that had a higher frequency and a lower amplitude?
Blow on the blue straw harder.
Blow on the yellow straw softer.
Blow on the purple straw harder.
Blow on the pink straw softer

If you tried to speak through a old fashioned telephone like the one above, which one of the following would give you the clearest sound?
One with a 30cm red string in between the two cups.
One with a 40cm red string in between the two cups.
One with a 60cm red string in between the two cups.
One with a 50cm red string in between the two cups.
How can you tell that a 200 Hz sound has less energy than a 300 Hz sound?
The sand jumps higher on the speaker with a 300 Hz sound than with a 200 Hz sound.
A 200 Hz tuning fork makes a higher pitched sound that a 300 Hz tuning fork.
The sand doesn't move on the speaker with a 200 Hz sound.
The 200 Hz sound makes a wave with a smaller wavelength than the 300 Hz sound.
Ms Clarke uses a tuning fork to make a sound with a frequency of 200Hz. What does she need to do to make a louder sound with frequency of 150 Hz?
Strike a tuning fork that has longer arms with a greater force
Strike a tuning fork that has longer arms with a smaller force
Strike a tuning fork that has shorter arms with a greater force
Strike a tuning fork that has shorter arms with the same force.
