  • Gravity and Buoyancy

    Gravity and BuoyancyLesson

    Students learn about environments with gravity and those with reduced gravity by observing the behavior of a water-filled plastic bag, both inside and outside of a container of water.

    Grades: 6-8
  • Skeletal Structures

    Skeletal StructuresLesson

    Students design and build an exoskeleton or endoskeleton for an animal of their own invention.

  • The Skeleton

    The SkeletonLesson

    Students learn about endoskeletons by observing, comparing and contrasting different kinds of chicken bones, and by relating their chicken bone observations to human bones.

    Grades: 6-8
  • Bone Structure: Hollow vs. Solid

    Bone Structure: Hollow vs. SolidLesson

    Students investigate and compare the weight-bearing capacity of solid and hollow cylinders, and use their findings to make inferences about bone structure.

    Grades: 6-8
  • Arm Model

    Arm ModelLesson

    Students construct a model arm and learn how muscles and bones work together to achieve efficient movement.

    Grades: 6-8
  • Muscle Fibers

    Muscle FibersLesson

    Students learn about the structure of muscles by comparing yarn and cooked meat.

    Grades: 6-8
  • Center of Gravity

    Center of GravityLesson

    Students learn about center of gravity and how the body adjusts to the force of gravity to remain balanced.

  • Good Stress for Your Body

    Good Stress for Your BodyLesson

    Students learn that muscles and bones must work to maintain or increase strength and endurance.
