5E lesson flow

  1. 01

    Engage

    5 min

    Teacher Does

    Pluck a stretched rubber band once. Ask students to watch and listen before giving the movement a science name.

    Students Do

    Watch, listen, and describe what they notice by pointing, acting, or speaking.

    Ask

    • What moved?
    • What did you hear?
    • What happened when the movement stopped?

    Look For

    Students notice back-and-forth movement and connect the movement with the sound.

  2. 02

    Explore

    10 min

    Teacher Does

    Guide pairs through a simple moving-versus-still rubber-band comparison. Keep the same band and box for both observations.

    Students Do

    Observe the band before touching it, pluck gently, watch and listen, then compare after the band stops.

    Ask

    • What stayed the same?
    • What changed?
    • When did you hear sound?

    Look For

    Students use the same object to compare vibrating and still conditions.

  3. 03

    Explain

    6 min

    Teacher Does

    Name the observed movement as vibration. Introduce sound source and evidence using the students' own observations.

    Students Do

    Act out a vibration and complete the oral frame: “I know it vibrated because I observed ___.”

    Ask

    • What does vibration mean?
    • What was the sound source?
    • What evidence did we collect?

    Look For

    Students use back-and-forth movement as evidence, not color, size, or shape.

  4. 04

    Elaborate

    8 min

    Teacher Does

    Show the membrane test. Place tiny paper pieces on tightly stretched plastic wrap. Play a nearby speaker at a comfortable volume, then turn it off.

    Students Do

    Compare the membrane and paper pieces with the speaker playing and off.

    Ask

    • What moved even though we did not touch it?
    • What changed when the speaker was turned off?

    Look For

    Students observe that sound can make nearby material vibrate.

  5. 05

    Evaluate

    6 min

    Teacher Does

    Use one new picture from Practice or the worksheet. Ask students to identify vibration and give one observation as evidence.

    Students Do

    Point, speak, or draw one piece of evidence.

    Ask

    • Which material is vibrating?
    • How do you know?

    Look For

    A correct identification plus a relevant observation such as back-and-forth movement.

Student goal

I can use what I see and hear as evidence that vibrations and sound are connected.

Learning objectives

  • I can tell when something is vibrating by watching it move back and forth.
  • I can connect a vibration with the sound I hear.

Materials

  • Small boxes or sturdy cups
  • Large classroom rubber bands
  • Hand drum or sturdy container with a flexible surface
  • Bowl or container
  • Plastic wrap
  • A few tiny paper pieces
  • Small speaker
  • Worksheet or recording sheet
  • Crayons

Before class

  • Stretch one large rubber band safely around each box or cup.
  • Stretch plastic wrap tightly over a bowl and place a few tiny paper pieces on top.
  • Test the speaker close to the membrane at a comfortable classroom volume so movement is visible without using loud sound.
  • Keep rubber bands away from faces and do not overstretch them.
  • Open Teach This Lesson and Practice before class.

Prior knowledge

  • Students can describe simple movement such as back and forth.
  • Students know that ears help us hear sounds.

Vocabulary

sound
Something we can hear.
vibration
A quick back-and-forth movement.
vibrate
To move back and forth quickly.
sound source
The thing that is vibrating to make a sound.
still
Not moving.

Differentiation

  • Read all student-facing prompts aloud.
  • Allow pointing, acting, or oral answers instead of writing.
  • Use the frame: “I know it vibrates because I see ___.”
  • Let students place two picture cards under MOVING and STILL before using the word vibration.
  • For extension, ask students to find another safe sound source and predict which part of it vibrates.

Assessment

  • Listen for students describing back-and-forth movement.
  • Check whether students connect the moving rubber band or drumhead with sound.
  • Check whether students identify the moving membrane or paper pieces as evidence that sound can make matter vibrate.
  • Use the exit response to distinguish evidence from unrelated features such as color.

Exit ticket

Show a moving and a still object. Ask: Which one is vibrating, and what is your evidence? Students may point and tell.

Extension

Find one safe classroom sound source. Point to or describe the part you think is vibrating when it makes sound.
