Overview:

In this hands-on lesson, students explore how sound is made and how we hear it. Through simple demonstrations and discussion, students learn that sound is caused by vibrations. They observe vibrations using a yardstick activity, feel vibrations in their own throats while speaking or singing, and identify common objects that produce sound. By the end of the lesson, students understand that the ear helps us hear and that all sounds are created by vibrating objects.

Grade Level:

Kindergarten – 2nd Grade

Subject:

Science – Physical Science (Sound)

Duration:

30–45 minutes

Learning Objectives:

Students will be able to:

  1. Identify the ear as the organ used for hearing.

  2. Explain that sound is caused by vibrations.

  3. Identify at least three objects that produce sound through vibration.

Academic Vocabulary:

  • Sound

  • Vibration

  • Eardrum

  • Vocal cords

  • Instrument

  • Loud / Soft

Materials:

  • Wooden yardstick

  • Table

  • Instrument images

  • Good Vibrations worksheet

  • Pencil/crayons

Optional Extension:

  • Rubber bands

  • Tissue box

  • Plastic wrap + rice

5E Instructional Model

1. Engage (Anticipatory Set)

Ask:

  • How do we hear?

  • How do we know where sound comes from?

  • What happens when someone claps?

Demonstrate a clap or whistle.

Introduce learning target:

“Today we will learn how sound travels to our ears and what makes sound.”

2. Explore (Hands-On Demonstration)

Yardstick Demonstration:

  • Place half of the yardstick off the table.

  • Bend and release.

  • Ask: What do you see?

Introduce the term: vibration.

Vocal Cord Activity:

  • Students place their hands on throat.

  • Sing together.

  • Ask: What do you feel?

Explain: Vocal cords vibrate to create sound.

3. Explain

  • Show instrument images.

  • Ask how each makes sound.

  • Explain: All sounds come from vibrations.

    • When something vibrates (moves back and forth quickly), it pushes on the air around it.

    • Those air movements travel to our ears.

    • Our ears detect those vibrations as sound.

Optional: Introduce a simple diagram of sound waves and the inner ear. Fun fact: the tiny bones in the ear can fit on a dime. They are the smallest bones in the human body.

4. Elaborate

Students:

  • Complete “Good Vibrations” worksheet.

  • Color items that produce sound.

  • Draw or list classroom items that make sound.

Extension:
Test classroom objects (tap the desk, drop the pencil, snap the fingers).

5. Evaluate

Formative Assessment:

Students must:

  • State what causes sound.

  • Identify 2–3 vibrating objects.

  • Explain what part of the body helps us hear.

Exit Ticket:
Draw one object that makes sound and label “vibration.”

Differentiation

Support:

  • Provide picture cards

  • Sentence frames:

    • “Sound is made when ______ vibrates.”

Enrichment:

  • Investigate loud vs. soft vibrations.

  • Compare string length and sound pitch.

  • Write short explanation paragraph.

Assessment Criteria

Students demonstrate mastery if they can:

  • Identify the ear as the hearing organ
  • Explain that sound is caused by vibration
  • Name or identify at least three sound-producing objects

State Standards Alignment (NGSS)

Kindergarten

  • K-PS2-1 (Pushes and Pulls)

    • Plan and investigate to compare the effects of different strengths or directions of pushes and pulls.

  • K-PS4-1 (Waves: Sound & Light)

1st Grade

  • 1-PS4-1 (Sound vibrations)
    • Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate.

2nd Grade

  • 2-PS1-1 (Observable properties)

    • Plan and investigate to describe and classify different kinds of materials by their observable properties (sound properties).
