• Only students 1 and 2 created a device to communicate with sound.

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

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

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

Fourth grade students were investigating sound. Group 1 wrapped rubber bands around a shoe box. Group 2 hung a ruler off the edge of a desk. 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 a sound and vibrating object.

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

Caiden and Davis are using a rubber band, 2 markers, and a box to learn about pitch. First, they stretch a rubber band around a box. Next, they place markers under the rubber band. They can move these markers to make the section of the rubber band that’s being plucked shorter and longer. Caiden makes a sound by placing the markers as seen in the picture above. He plucks the rubber band with his finger. Davis wants to make a higher pitch sound than the one that Caiden made. Which picture shows how he should place the markers so that when he plucks the rubber band, it will result in a higher pitch?

Haley 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

• Yes, she will be able to create different pitches of sound if she hits one bottle lightly and the other bottle very hard.

• 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.
