Fourth grade students all created different ways to investigate sound. Which of the following will both groups encounter when producing sound?

• Only group 1 will hear sound because rubber bands are used to create vibrations when pulled on.

• Both groups will move an object that will create a response with a sound and vibrating objects.

• Only group 2 will hear sound because the ruler will vibrate and create a sound.

Liz is working on her plan to create a device that will use sound waves to communicate yes or no answers to her friend's questions. She fills two glass bottles with the same amount of water. The picture shows her device. She will tap each of the bottles once with a spoon to create two different sounds. One bottle will produce a high pitch sound when tapped with the spoon, and the other bottle will make a low pitch sound. She explains to her friend that the lower pitch means "no" and the higher pitch means "yes." Will her device be able to communicate the yes or no messages using different pitches?

• Yes, she will be able to create different pitches of sound because both bottles are filled with water all the way to the top.

• No, she will not be able to produce any sound at all because the jars are filled with water.

• No, she will not be able to produce different pitches. Both bottles will have the same pitch when tapped with the spoon because the water levels are the same.

The following students made devices to communicate with friends across the room.

What is similar about how all three of these devices will be used to communicate?

Student 1 Uses paper to make a megaphone

Student 2 Uses cups and strings to make a telephone

Student 3 Uses metal cans to build a drum

• They are all created in order to speak to one person to another.

• They are all created in order to communicate with light.

• They will all produce vibrations, which will result in a sound.

Three students wanted to investigate sound and vibrations with the same materials. One student flicked a string every 10 seconds, one student flicked a string every 5 seconds, and another student flicked a string every 2 seconds. What will the students observe?

• Speed does not impact vibrations or sound.

• The string was the highest pitched sound when vibrating the fastest.

• The string was the highest pitched sound when vibrating the slowest.
