Sensory Detectives Lesson Guide Occupational Therapy & Classroom Integration
Sensory Detectives Lesson Guide
Duration: 45–55 Minutes
Audience: Grades 3–8 / OT Co-Teach
Instructional Purpose & Rationale
Students explore how sensory input directly impacts their nervous system arousal ("engine speed"). Through neurodiversity-affirming exploration, learners identify personal sensory triggers and build customized regulatory toolkits for sustained academic participation and emotional well-being.
Core Objectives
Identify the 8 sensory channels.
Recognize personal arousal states.
Select 3 target regulation tools.
Sensory Systems Focus: The Foundational 8
Proprioception
Muscles & joints: heavy work, deep pressure, calming grounding.
Vestibular
Balance & head movement: linear resets arousal; rotary excites.
Interoception
Internal body signals: heart rate, hunger, bathroom, breathing rate.
Tactile
Touch & texture: light touch alarms; firm touch stabilizes.
Auditory
Sound volume & frequency: white noise, rhythm, noise reduction.
Visual
Light & clutter: fluorescent glare, dimming, visual boundaries.
Oral Motor
Chewing & drinking: crunch, resistance, straw sipping for focus.
Olfactory
Scent sensitivity: fresh air, calming lavender, alerting citrus.
Structured Lesson Delivery Arc

Lesson Phase
Educator Facilitation & Student Actions
10 Min
Hook & The Engine Concept
Introduce the car engine metaphor (Low/Sluggish, Just Right/Cruising, High/Racing). Emphasize that all states are natural; tools help shift gears.
15 Min
Sensory Lab & Heavy Work Trial
Project the slide deck. Conduct 3 mini-experiments: chair push-ups (proprioception), cross-body tapping, and rhythmic breathing. Students notice pulse and body feel.
15 Min
Personal Toolkit Building
Distribute the Sensory Toolkit Worksheet . Students categorize sensory preferences (Seeker vs. Avoider tendencies) and select 3 desk-ready strategies.
10 Min
Synthesis & Classroom Norms
Establish classroom sensory agreements: Tools are for learning, not toys. Introduce the Sensory Break Menu anchor chart for daily independent access.

Intervention Matrix & Accommodations
Engine States & Environmental Adjustments
OT Best Practices
The Three Engine States: Symptoms & First-Line Strategies
Low Engine (Sluggish) Under-Aroused
Head on desk, slow processing, slouching, daydreaming, low pencil grip pressure.
Alerting Input: Jumping jacks, crunchy snack, cold water sip, standing desk, fast upbeat rhythm.
Just Right (Optimal) Regulated
Upright posture, receptive eye focus, steady breath, engaged with tasks, able to shift focus.
Maintenance: Periodic posture resets, micro-stretches, hydration, structured visual checklists.
High Engine (Overdrive) Over-Aroused
Fidgeting, fast speech, vocal noises, bumping into desks, tactile defensive reactions.
Calming Input: Chair push-ups, weighted lap pad, 4-7-8 breathing, noise-dampening earmuffs.
Environmental Classroom Accommodations (Universal Tier 1)
Visual & Auditory Adjustments
Turn off half the fluorescent banks; utilize natural window light or warm floor lamps.
Establish visual boundaries (tape on carpet, desk carrels for independent work).
Provide communal noise-cancelling headphones near the quiet library shelf.
Use soft chimes or gentle light flicker instead of shouting to gain class attention.
Seating, Movement & Heavy Work
Incorporate resistance bands around desk legs for active foot bouncing.
Offer wiggle cushions (disc sitters) or kneeling options during seatwork.
Assign classroom jobs requiring heavy work (carrying book bins, stacking chairs, wiping boards).
Designate a clearly defined "Reset Corner" with tactile tools and deep breathing visuals.
Affirming Teacher Scripting Prompts
Instead of: "Sit still and stop tapping!"
Say: "I notice your body needs movement right now. Let’s do 5 wall push-ups or grab your foot band so your hands can write."
Instead of: "Why are you putting your head down?"
Say: "Looks like your engine is in low gear. Would you like a sip of cold water or a quick stretch before we begin problem 3?"

Sensory Science
Meet the "Secret Three" Senses
You know sight, sound, touch, taste, and smell—now discover your hidden power senses!
Proprioception
Muscles & Joints sense where your body is in space and how much strength to use.
Clue: Pushing & lifting
Vestibular
Inner ear balance sense detects movement, spinning, tilting, and speed.
Clue: Rocking & swinging
Interoception
Internal body clues detect your heart rate, full tummy, thirst, and temperature.
Clue: Heartbeat & stomach
Every body feels and processes these signals in its own unique way.
Self-Awareness
How Is Your Engine Running?
Just like a car, your nervous system runs in different gears throughout the day.
LOW GEAR
Sluggish & Sleepy
• Head resting on desk
• Yawning, daydreaming
• Hard to start tasks
Need: Upbeat movement & cold water
JUST RIGHT
Calm & Focused
• Sitting comfortably
• Ready to listen and write
• Body feels steady
Need: Keep cruising along!
HIGH GEAR
Buzzy & Overdrive
• Fast talking, fidgeting
• Bumping into things
• Frustrated or overwhelmed
Need: Heavy work & deep breaths
Notice your state without judgment: every engine changes gears, and you can shift it!
The OT Superpower
Heavy Work: The Nervous System Reset
Pushing, pulling, and lifting sends deep organizing signals to your brain.
Chair Push-Ups
Place both hands flat on your chair next to your hips. Press down firmly to lift your body off the seat for 5 seconds.
Result: Stabilizes joints and calms buzzing energy.
Wall Presses & Squashes
Face a solid wall with hands flat at shoulder height. Push against the wall with steady force, counting slowly to 10.
Result: Grounds your whole body and activates posture muscles.
OT Fact: Heavy work calms high engines AND alerts low engines!

Part 1: Check Your Engine Speed Right Now
Tune into your internal cues (interoception). Select the gear that best describes your body right now:
Low Gear
Sleepy, sluggish, head down, slow thoughts.
Just Right
Steady, focused, alert, calm, ready to learn.
High Gear
Buzzy, racing, fidgety, loud, overwhelmed.

Touch & Pressure
Squeezing therapy putty or a squishy stress ball Rubbing a textured strip taped under my desk Having a weighted lap pad during reading time Wearing a soft sweater or smoothing my palms flat
Sound & Vision
