  • 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.

  • 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.

  • 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.

  • Arm Model

    Arm ModelLesson

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

  • Muscle Fibers

    Muscle FibersLesson

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

  • 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.

  • Muscles and Bones: Nutrition

    Muscles and Bones: NutritionLesson

    Students learn about the nutritional needs of our bones and muscles, and how to make healthy food choices, especially in terms of getting enough calcium.

  • Muscles and Bones in Space

    Muscles and Bones in SpaceLesson

    Students learn how our muscles and bones change during space missions, and then devise preventative solutions to help limit those changes.
