About this worksheet

What students practice

Students use drum-test evidence to explain how vibrating materials make sound.
Students use observations to explain how sound can make other materials vibrate.
Students compare sound-station designs using investigation results.

How to use

Read the tests and questions aloud. Have students use the observations to choose designs and explain their choices. The tests are described; no equipment is needed.

Mountain Shelter Sound Builders

Use sound tests to help plan a trail sound station.

Test a Drum

Listen to the test notes. Use them to answer each question.

A Sound Station by the Trail

A trail club is building a sound station at a mountain shelter. Visitors will try a drum and a speaker. First, the club tests two drum designs. An adult holds the same drum by its edge and gives it the same gentle tap each time.

Design A has nothing on the drum top. Its top moves back and forth, and a clear beat rings out. Design B has a soft pad pressed against the top. Its top barely moves, and the tap makes a short, dull sound.

To vibrate means to move back and forth. Which part vibrates to make the clear beat?

A. The edge held by the adult
B. The pad pressed on the top
C. The top with nothing on it
D. The ground under the drum

The club wants a beat that rings out. Which design should it choose?

A. Design A, because its top can move
B. Design B, because its pad stops motion
C. Design A, because its top stays still
D. Design B, because its pad makes motion

The clear beat is ringing. An adult presses the pad against the moving drum top. What will most likely happen?

A. The top will move more, making a louder beat.
B. The top will stop moving, but the beat will stay the same.
C. The pad will keep the beat ringing longer.
D. The top will move less, and the beat will fade.

A helper taps Design A hard and Design B gently. Why is this not a fair way to compare the two designs?

A. Both tests use the same drum.
B. The taps change as well as the pad.
C. The helper listens to both sounds.
D. Both tests happen at the shelter.

Test Moving Paper

Listen to the new test notes. Think about what makes the paper bits move.

A Bowl Beside a Speaker

An adult puts tiny paper bits on a thin, tight cover over a bowl. A speaker sits close to the bowl but does not touch it. Nobody touches the bowl during the tests. The club watches for the bits to jiggle.

With the speaker off, the bits stay still. The adult plays one low note quietly. The bits stay still. The adult plays the same note louder, at a safe volume. The bits jiggle. Next, the adult moves the bowl farther away. With the same louder note, the bits stay still. The club can still hear the note.

What best explains why the bits jiggled near the speaker?

A. The speaker bumped the bowl.
B. Someone tapped the bowl cover.
C. The sound made the cover shake.
D. The still paper bits made the note.

Circle the TWO observations that together show sound moved the bits without a push from a person or the speaker.

No person or speaker touched the bowl.The drum made a dull tap under a pad.The bits jiggled when the louder note played nearby.The sound station is at a mountain shelter.

The club will test near and far bowl spots again. What should stay the same to test only the distance?

A. The space between the bowl and speaker
B. The number of times someone taps the bowl
C. The spot where the bowl sits
D. The note and its loudness

A visitor says, “The faraway bits stayed still, so there was no sound.” Which observation shows the mistake?

A. The bits were tiny and light.
B. The bowl had a tight cover.
C. The adult moved the bowl farther away.
D. The club still heard the note.

Plan the Sound Station

Use both tests to help the trail club choose and improve its designs.

The station has two goals: the drum should make a clear, ringing beat, and sound from the speaker should make the paper bits jiggle. The speaker must not touch the bowl.

Which plan meets BOTH goals in the tests?
