Lesson overview

What students will learn

  • Use a physical model to connect bones, joints, tendons, and muscle pulling to finger movement.
  • Collect evidence from model tests showing that pulling on different sides produces different joint motion.

Key science ideas

  • Bones provide rigid structures that can move at joints.
  • Muscles pull when they contract; they do not push bones from a distance.
  • Tendons connect muscles to bones and transmit pulling force.
