Materials Needed

• Black construction paper (2 sheets)
• White Q-tips (cotton swabs) – about 20-30
• White school glue
• White chalk or a white crayon
• A small hand mirror
• A hard book and a soft pillow (for the hook)
• Optional: A printable skeleton diagram or a toy skeleton

Learning Objectives

By the end of this lesson, students will be able to:

• Identify the skeleton as the internal frame of the human body.
• Explain the two main jobs of bones: support (standing up) and protection (keeping insides safe).
• Locate and name at least three major bones (Skull, Ribs, Spine).
• Create a visual representation of a skeleton using mixed media.

Success Criteria

• I can explain what would happen if I had no bones.
• I can feel and point to my "helmet" bone (skull) and my "staircase" bone (spine).
• I can build a Q-tip skeleton that shows a head, spine, arms, and legs.

1. Introduction: The Hook (10 Minutes)

The "Jelly vs. Building" Challenge:

• Place a soft pillow and a hard book on the table. Ask the students: "If you wanted to build a tall tower, would you use the pillow or the book as the base? Why?"
• Discussion: Explain that our bodies are like buildings. Without a frame, we would be like a puddle of jelly on the floor! We couldn't sit up to eat or run to play.
• The Big Question: "What is the hard frame inside your body called?" (The Skeleton).

2. Body: Content & Practice (20 Minutes)

I Do: The Tour of the Frame

Explain the skeleton using 7-year-old friendly analogies:

• The Skull: It’s your "Natural Helmet." Tap your head gently. It protects your brain, which is soft like playdough.
• The Ribs: These are your "Body Cage." They wrap around your heart and lungs to keep them from getting bumped.
• The Spine: This is your "Main Pillar." It’s made of little bones like a bead necklace that lets you bend and twist.

We Do: Bone Detectives (Active Exploration)

Guide the students in a "Body Scan" to find their bones:

1. The Jaw: Open and close your mouth while looking in the mirror. Can you feel the hinge? That’s a joint!
2. The Knuckles: Make a fist. Feel the hard bumps? Those help your fingers move.
3. The Spine: Reach around and feel the "bumps" down the middle of your back.
4. Game - Skeleton Simon Says: "Simon says touch your Natural Helmet (Skull)." "Simon says wiggle your Main Pillar (Spine)."

You Do: Q-Tip Skeleton Art

Students will now apply what they’ve learned by "building" a skeleton.

1. Give each student a piece of black paper.
2. Ask them to draw a simple skull shape at the top with white chalk.
3. Using glue and Q-tips, have them create the skeleton:
   • One long Q-tip for the spine.
   • Smaller pieces (cut by adult if needed) for the ribs.
   • Long Q-tips for the arms and legs.
4. Creative Choice: Students can glue their skeleton in a "dancing," "running," or "sitting" pose to show how bones help us move.

3. HASS Integration: My Body in My World

Discussion: "Everyone has a skeleton, but every body is special! How does your skeleton help you do the things you love in our family or at school?" (e.g., "My skeleton helps me hold my baby brother," or "My skeleton helps me kick a soccer ball with my friends.")

4. Conclusion & Recap (5 Minutes)

• Summary: "Today we learned that our skeleton is our body’s secret frame. It keeps us upright, protects our soft insides, and helps us move."
• The "Exit Ticket" Question: "If you could pick one bone that is the most important, which one would it be and why?"

Differentiation & Adaptability

For the Neurotypical Twin:

• Extension: Challenge them to count how many ribs they can feel or research how many bones an adult has (206) versus a baby (around 300).
• Complexity: Ask them to label the bones on their Q-tip art using white crayon.

For the ASD Twin:

• Sensory Support: If the "sticky" feeling of glue is aversive, use a glue stick or double-sided tape. If the tapping on the head is overstimulating, use a stuffed animal to demonstrate.
• Visual Schedule: Use a simple 1-2-3 checklist: 1. Feel bones, 2. Play Simon Says, 3. Make Q-tip art.
• Predictability: Give a 2-minute warning before transitioning from the active "Simon Says" game to the seated art activity.

Universal Adaptations:

• Classroom: Use a life-sized "Paper Person" tracing on the floor and have students work in pairs to place "bone" labels.
• Physical: If fine motor skills are a challenge, use white playdough "snakes" instead of Q-tips to form the bones.

Assessment Methods

• Formative: Observation during "Bone Detectives" scan. Can the student locate the ribs and skull on themselves?
• Summative: The completed Q-tip skeleton. Does it show a basic understanding of a central spine with limbs attached?
• Verbal: The student can name two jobs of the skeleton (Support and Protection).
