What we will do

  1. 1

    Choose your way

    Choose a quiet sound demonstration or a silent close-up.

  2. 2

    Find the end

    Find the ruler end extending beyond the table.

  3. 3

    Watch movement

    Watch the ruler end move back and forth.

  4. 4

    Direct a stop

    Ask the teacher to stop the ruler.

  5. 5

    Compare stopped motion

    Notice the ruler end when it is still.

  6. 6

    Connect the evidence

Teacher & para guideMaterials, learning objectives, access, and safety

Materials

  • Long intact flexible plastic ruler with rounded edges; secure clamp operated by teacher; optional captioned close-up video; existing AAC and hearing protection. No rubber bands, rice or small parts.

Safety first

Keep learners seated at a shared display; offer observation without touch and AAC, gaze, gesture or speech. Honor NO, STOP and BREAK; allow wait time and follow individual vision, allergy, mouthing and supervision plans. Select support individually, never by age or House. Check consent before each quiet demonstration. Offer a silent captioned close-up and hearing protection; never require listening or touching. A teacher clamps and operates an intact flexible plastic ruler with rounded edges. No rubber bands, rice or small parts. Compare moving/sounding and still/quiet, using the video’s evidence when listening is declined.

Follow each student's IEP, health, feeding, allergy, behavior, and mobility plans.

Individual learning objectives

Choose Level 1, 2 or 3 individually in either House group. A House is not an ability level. Watching, directing and communicating a boundary are valid participation.

Level 1

Select SOUND or QUIET.

Level 2

Identify the part moving back and forth.

Level 3

Use start/stop evidence to connect sound and vibration.

Skill focus: Auditory discrimination, vibration awareness, cause-and-effect, scientific observation

30-minute teaching sequence

Introduce · 5 min

5 min: Offer SOUND/QUIET and STOP choices before demonstrating. Show a long plastic ruler secured to a table. Explain, "Vibrate means move back and forth." Students may watch a silent close-up instead of hearing the demonstration.

I do · 10 min

I do 10 min: Secure an intact flexible ruler with its end over the table. Gently release the end to produce a quiet twang. Point out back-and-forth movement, then stop it. Compare moving/sounding with still/quiet; repeat gently, only after checking consent for sound.

We do · 10 min

We do 10 min: Students direct START/STOP while the teacher operates the ruler. L1 selects SOUND/QUIET. L2 points to the vibrating end. L3 predicts what stopping the movement will do, then checks. Offer a silent video with captions for sound-sensitive students.

Exit choice · 5 min

L1: Sound or quiet? L2: What vibrated? L3: What happened to the sound when movement stopped? Accept AAC, gaze, gesture or speech. Record support.

Science note: Vibrate means move back and forth.

Curriculum connection: NGSS 1-PS4-1 connection.

Prepare for this learner

Both House groups: choose L1/L2/L3 individually, never by age. Stay seated; teacher controls materials. Offer speech, AAC, pointing or gaze, 1-2 high-contrast choices, wait time, observation/no-touch and NO/BREAK. Record response and support; honor refusal.

Record the response, access method, opportunities and support used. Record observed, declined or not assessed separately; a communicated refusal is not a failure of participation.

Access supports

Communication Model five core words; accept speech, AAC, eye gaze, gestures, object choices, signs, and partner-assisted scanning.

Sensory Present one material at a time. Offer tools, gloves, observe-only, a scent-free choice, and a quiet break.

Motor Stabilize containers, pre-loosen parts, use adapted grips, and offer seated, standing, partner, or directing roles.

Learning Show the finished result, model first, use short visual steps, repeat, and record the least support needed.
