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.
Students design and build an exoskeleton or endoskeleton for an animal of their own invention.
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. SolidLesson
Students investigate and compare the weight-bearing capacity of solid and hollow cylinders, and use their findings to make inferences about bone structure.
Students construct a model arm and learn how muscles and bones work together to achieve efficient movement.
Students learn about the structure of muscles by comparing yarn and cooked meat.
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 BodyLesson
Students learn that muscles and bones must work to maintain or increase strength and endurance.
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 SpaceLesson
Students learn how our muscles and bones change during space missions, and then devise preventative solutions to help limit those changes.
