💡 Big idea: Controlled movement requires paired muscles: an agonist that contracts and an antagonist that resists, with synergists stabilizing the joint.
- 0-8Intro: agonist, antagonist, synergist definitions with elbow example
- 8-25Notes: muscle pairing logic and three roles
- 25-45PLTW online task: muscle pairing
- 45-62Choose one movement; identify agonist, antagonist, and synergist
- 62-75Revise Maniken label card to mark roles; submit revised photo or diagram
- 75-80Class share: which movements produced the most disagreement?
- • Yesterday you placed muscles. Today you explain how they cooperate. No muscle works alone.
- • For every movement, one muscle is the prime mover, another resists, and one or more stabilize the joint. Those roles have names.
- • You will pick one movement from your Maniken build and label every muscle involved by its role. Then you revise the Maniken labels to match.
- • This analysis is the kind of thinking physical therapists and athletic trainers use every day.
- 1Read the notes on agonist, antagonist, and synergist roles in movement.
- 2Choose one joint movement and identify the agonist and antagonist muscles.
- 3Complete the PLTW online task on muscle pairing.
- 4Revise your Maniken labels to mark each muscle's role in one movement.
- 5Submit your agonist-antagonist analysis and revised labels.
- • You can identify agonist and antagonist muscles for a movement.
- • You can revise model labels to show muscle roles.
- • Agonist: the prime mover contracting to produce a specific movement. Antagonist: the muscle on the opposing side that relaxes and resists. Synergist: stabilizes the joint during the movement.
- • Classic pair: biceps brachii (agonist, elbow flexion) and triceps brachii (antagonist). Reversed for elbow extension.
- • Muscle imbalance between agonist and antagonist pairs is a common cause of overuse injury and movement dysfunction.

Unit 1.2 Muscles and Motion: Muscle contraction, muscle orientation, Maniken muscle build, movement and biomechanics. · Muscle action analysis
Day 4 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete the agonist-and-antagonist analysis task in Lesson 1.2 Muscles and Motion on myPLTW; use it to check your model labels during the analysis window.
Mark the agonist-antagonist task complete after submitting your revised model labels.
Maniken task is done; today the analysis task should show complete and your revised labels should be submitted.
myPLTW completion status plus submitted revised label sheet.
All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.
Today's PLTW tracker
Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

Maniken task is done; today the analysis task should show complete and your revised labels should be submitted.
This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.
