Science B27: THe Human Machine


Award-winning video and lesson investigations for young children on the topic of muscles and movement

Product Description

Video and lesson investigations on the topic of muscles and movement. Key concepts include:

  • Animal bodies are held in shape by their skeletons.
  • Skeletons are made from lots of bones.
  • Bones do not bend. Movement in skeletons happens at joints.
  • Muscles control movement of joints.
  • Muscles can only work by pulling on bones.
  • The muscles contract (shorten) as they pull.
  • Muscles usually operate as opposing pairs.
  • Like machines, our bodies consist of a framework with moving parts.
  • Joints are like turning points (or pivots) of levers.
  • One muscle, or a set of muscles, contracts and pulls on the bones to cause movement.
  • This muscle cannot push the bone back again, but another muscle, or a set of muscles, is used for this.
