Matter Explorers Lesson Plan Special Ed Science Guide NGSS 2-PS1-1 • Grades K–5 Support
Matter Explorers: Physical Properties
Suggested Duration
45–60 Minutes
Essential Question
"How can we use our senses to observe, touch, and describe what objects are like?"
Key Learning Targets (I Can...)
Observe: Name or point to an object's color, shape, and size.
Feel & Compare: Identify texture (rough/smooth, soft/hard).
Test: Check if an item is bendy (flexible) or stiff (rigid).
Multisensory Classroom Materials Needed
Tactile Realia Sponges, rocks, pom-poms, sandpaper, plastic spoons, pipe cleaners, erasers.
Sensory Tools 1 "Mystery Touch Bag" (opaque fabric), magnifying glasses, color sorting cups.
Visual Supports Picture communication cards, slide deck, Detective Worksheet, Exit Ticket.
Instructional Delivery: Step-by-Step
Phase 1: Sensory Mystery Hook (10 Mins) Engage
Introduce the "Mystery Feely Bag" containing one soft item (cotton ball) and one hard item (wooden block). Invite a student volunteer to reach in without peeking.
Teacher Script: "Reach in! Don't look with your eyes—look with your fingertips. Does it feel bumpy or smooth? Is it squishy or hard?"
Phase 2: Visual & Explicit Model (15 Mins) Slides 1–5
Display the Matter Mystery Slides . Walk through the core physical properties one at a time using high-contrast icons:
👀 Color Red, Blue, Green
📐 Shape Round, Square, Flat
✋ Texture Rough, Smooth, Soft
🌀 Flex Bendy vs. Stiff
Sensory Note: For students with tactile defensiveness, allow object exploration inside clear sealed zipper bags or offer tongs/chopsticks before direct skin contact.
Activity Stations, Differentiation & Scaffolds
Part 2 of 2
Phase 3: Hands-On Exploration Stations (15 Mins) Worksheet
Students receive the Matter Detective Worksheet . Pairs rotate or choose 2 real objects from their sensory table (e.g., a bumpy rock and a bendy pipe cleaner). Students test, feel, and record findings using icon checkboxes.
Phase 4: Synthesis & Exit Quick-Check (10 Mins) Exit Ticket
Review with the Slide Deck "Mystery Reveal" game. Distribute the visual 3-question Exit Ticket. Support students with read-aloud and pointing options.
3-Tiered Differentiation & Universal Design for Learning (UDL)
Tier 1: Emerging High Support
Non-verbal learners, AAC communicators, or students needing maximum tactile modeling.
• Pointing to 2-choice picture cards (e.g., "Is this soft or hard?")
• Hand-under-hand sensory guidance
• Use AAC switch / core board icon for "feel"
Tier 2: Developing Moderate Support
Students who circle visual choices and express 1–2 word descriptions with verbal prompts.
• Circling icon checkboxes on worksheet
• Sentence strip: "The rock is [hard]."
• 1-to-1 tactile sorting with visual anchor cards
Tier 3: Expanding Low Support
Students who write simple property words and compare two contrasting materials.
• Copy or spell descriptive words from bank
• Compare: "The sponge is soft, but rock is hard."
• Complete sorting challenge independently
Visual Communication Sentence Frames
1
Observation Frame "This object is [color / shape]."
2
Tactile Frame "When I touch it, it feels [soft / hard / rough]."
Common Student Misconceptions: Students often confuse "heavy" with "hard" or think all flexible items must be soft. Emphasize bending without breaking (e.g., an aluminum ruler or plastic spoon bends even though it is hard).

Property 4
Hardness
Can you squish it with your fingers?
Soft Squishes easily (sponge)
Hard Holds shape (wooden block)
Can It Bend? Flexibility
Action Clue
Test gently with two hands! Does it change shape without breaking?
Bendy (Flexible)
It bends, curves, or twists and does not break!
Examples: Pipe cleaner, rubber band
Stiff (Rigid)
It stays straight and resists bending!
Examples: Wooden ruler, metal spoon
