Sound & Vibrations: How Wiggles Become Music

Students change the pitch and volume of a sound wave and discover that every sound — from a whisper to a drum — starts with something vibrating.

Learning Objectives

Students will be able to…

  • ✓Explain that sound is made by vibrations.
  • ✓Describe how pitch depends on how fast something vibrates.
  • ✓Describe how volume depends on how big the vibration is.
  • ✓Explain that sound travels through solids, liquids, and gases.

The Sound Wave Lab

Project this and let students change the pitch and the volume. Have them describe how the wave changes and connect each change to a sound they know.

The Lesson · 5E Model

45 minutes, five moves

Tap any phase to open the teacher moves and student actions.

1

Engage — Feel the Buzz

5 min

Hum with a hand on your throat. What do you feel?

👩‍🏫 Teacher Moves

  • Have students hum with a hand on the throat.
  • Ask what they feel (a buzz — a vibration).
  • Connect the buzz to making sound.

🎒 Student Actions

  • Feel the vibration while humming.
  • Describe what stops when they stop humming.
  • Record a first idea in their notebook.
2

Explore — The Sound Wave Lab

12 min

Students shape the wave with two sliders.

👩‍🏫 Teacher Moves

  • Send groups to the Sound Wave Lab above.
  • Ask them to change pitch, then volume.
  • Prompt: “What part of the wave changes each time?”

🎒 Student Actions

  • Change pitch and watch the number of waves.
  • Change volume and watch the wave height.
  • Match a change to a real sound.
3

Explain — Pitch & Volume

12 min

Two dials on every sound.

👩‍🏫 Teacher Moves

  • Explain sound comes from vibrations.
  • Faster vibration = higher pitch.
  • Bigger vibration = louder volume.

🎒 Student Actions

  • Explain what makes a sound high or low.
  • Explain what makes a sound loud or soft.
  • Label a wave’s pitch and volume.
4

Elaborate — Sound on the Move

11 min

How does sound reach your ears?

👩‍🏫 Teacher Moves

  • Explain sound travels through air, water, and solids.
  • Demo a string-and-cup “telephone.”
  • Connect to instruments and how ears hear.

🎒 Student Actions

  • Predict where sound travels fastest.
  • Explain how the cup phone carries sound.
  • Explain how a guitar changes pitch.
5

Evaluate — Exit Ticket

5 min

Three quick checks on sound.

👩‍🏫 Teacher Moves

  • Hand out the exit ticket below.
  • Look for vibration + pitch/volume ideas.
  • Collect as formative data.

🎒 Student Actions

  • Explain what makes sound.
  • Explain pitch vs. volume.
  • Explain how sound reaches the ear.

QUESTION 1
What makes sound?
Sound is made by vibrations — something moving back and forth quickly, like vocal cords, a drum skin, or a guitar string.
QUESTION 2
What is the difference between pitch and volume?
Pitch is how high or low a sound is (from how fast something vibrates). Volume is how loud or soft it is (from how big the vibration is).
QUESTION 3
You pluck a guitar string harder. What happens to the sound, and why?
It gets louder — plucking harder makes a bigger vibration, and a bigger vibration means more volume.

Going deeper? Build a cup telephone.

Connect two cups with a tight string and have students talk through it — proof that sound vibrations travel through a solid. A printable build-and-test sheet is in the Science library.
