Muscles and Movement: How We Move

Movement relies on dynamic interaction, so hands-on modeling and role-play let students feel how muscles, tendons, and bones work together. Active tasks turn abstract ideas like levers and antagonistic pairs into concrete experiences they can see and test with their own bodies.

• 4 activities

Activity 01

• Simulation Game
• 35 min · Pairs

Pairs: Elastic Arm Model

Pairs use cardboard for bones, wooden dowels for joints, and elastic bands for biceps and triceps. Attach strings as tendons, then take turns pulling bands to flex and extend the arm. Record how pairs oppose each other and share observations.

Analyze how muscles and bones work together to create movement.

Facilitation Tip

During Elastic Arm Model, ask each pair to label the muscle, tendon, and bone on their diagram so students connect the model directly to their own anatomy.

What to look for

Ask students to stand and perform a bicep curl motion. Then, ask: 'Which muscle is contracting to bend your elbow? Which muscle is relaxing?' Have them write their answers on mini-whiteboards.

Activity 02

• Simulation Game
• 40 min · Small Groups

Small Groups: Tendon Tug Demo

Groups tie string between a spring and a bone model, simulating a tendon. Stretch the spring to show muscle pull transmission, then add weight to test limits. Compare results and note ligament roles by adding tape between bones.

Explain the difference between antagonistic muscle pairs.

Facilitation Tip

In the Tendon Tug Demo, have students time how long the lever holds the mass before slipping to quantify tendon efficiency.

What to look for

Pose the question: 'Imagine you are a surgeon needing to repair a torn tendon. Why is it crucial to understand how muscles, bones, and joints work together?' Facilitate a brief class discussion, guiding students to mention force transmission and joint stability.

Activity 03

• Simulation Game
• 30 min · Whole Class

Whole Class: Antagonistic Relay

Divide class into teams. Students run to a station, pose in bicep curl or tricep extension while naming the active muscle, then tag next teammate. Debrief on pairs and skeleton support.

Evaluate the importance of tendons and ligaments in supporting movement.

Facilitation Tip

For the Antagonistic Relay, enforce a 10-second hold during each role so students feel the effort and timing of contraction and relaxation.

What to look for

Provide students with a diagram of a leg joint. Ask them to label one antagonistic muscle pair and explain in one sentence how they work together to straighten the leg.

Activity 04

• Simulation Game
• 25 min · Individual

Individual: Muscle Mapping

Students draw their arm skeleton, label antagonistic pairs, tendons, and ligaments. Colour contracting muscles during actions like lifting, then self-assess against a model.

Analyze how muscles and bones work together to create movement.

Facilitation Tip

Have students draw their muscle map on plain paper showing origin, insertion, and direction of pull before labeling tissues.

What to look for

Ask students to stand and perform a bicep curl motion. Then, ask: 'Which muscle is contracting to bend your elbow? Which muscle is relaxing?' Have them write their answers on mini-whiteboards.

A few notes on teaching this unit

Teach this topic through multi-sensory activities because motor memory reinforces learning. Avoid long lectures on muscle names; instead, focus on function and interaction. Research shows that students grasp levers and force transfer better when they build models and measure outcomes rather than just observe diagrams.

Students will explain that muscles only pull bones by contracting, that tendons transmit force, and that ligaments stabilize joints. They will use correct terminology and demonstrate how antagonistic pairs switch roles to produce smooth movement.

Watch Out for These Misconceptions

• During Elastic Arm Model, watch for students who say the elastic band pushes the forearm away from the shoulder.

  Have them place their hand on their biceps while performing a curl to feel the muscle shorten and pull, then ask how the opposite muscle must behave to straighten the arm.

• During Tendon Tug Demo, watch for students who confuse the string representing a tendon with the string representing a ligament.

  Ask them to cut the string at the joint and observe how the model collapses without the string holding bones together, clarifying that ligaments prevent dislocation.

• During Antagonistic Relay, watch for students who think bones move without muscle input.

  Pause the relay and have participants release their 'muscles' to show that the 'bone' stays still, reinforcing that bones are passive levers moved only by contracting muscles.
