Mississippi Science HAP.5.1
The Standard
- HAP.5
- Students will investigate the structures and functions of the muscular system, including the cause and effect of diseases and disorders.
Develop and use models to illustrate muscle structure, muscle locations and groups, actions, origins, and insertions.

What This Standard Means
What Students Need to Do
- Students make a model showing where muscles sit, how their fibers form bundles, and how tendons attach them to bones. They mark each muscle’s origin and insertion, then show how shortening the muscle moves a joint.
What Mastery Looks Like
- On an arm model, a student places the biceps on the front and triceps on the back. They label the biceps origin on the scapula and insertion on the radius, then show how it bends the elbow.
Common Misconceptions
- Students may draw muscles as solid blocks instead of bundles of fibers, or leave out the tendons. They may think muscles push bones, or swap the biceps origin and insertion.
How to Assess It
- Give students an arm outline marked with the scapula, humerus, and radius. Ask them to draw and label the biceps, its fiber bundles, tendons, origin, and insertion, then show what moves when it shortens.

Ways to Teach It
Build a paper arm with brads and yarn; label the biceps and triceps, their attachments, and the movement each produces.
Ask: Why can the biceps bend the elbow but not push it straight? Write an answer using origin, insertion, and contraction.
Give pairs cards with muscle names, body locations, origins, insertions, and actions; have them build and explain matching sets.
Have students lift a backpack, then trace the biceps from scapula to radius on an arm diagram and explain its pulling action.
