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

Product Description

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

  • Levers can make it easier to move things.
  • With some levers, the object to be moved is at one end of the lever and push or pull is exerted on the other end.
  • There are different kinds of lever but all levers need a point about which the lever can turn (the pivot).
  • Where the pivot is positioned is important.
  • Some types of lever convert a small force at one end into a larger force at the other.
  • The strength of the levering force is affected by the position of the pivot.
  • With some levers, eg. A nutcracker, the pivot (or fulcrum) is at the end and there are two lever arms which work together to get the job done.
