Award-winning video and lesson investigations for young children on the topic of surface tension.

Product Description

Award-winning video and lesson investigations on the topic of surface tension. Key concepts include:

  • Water behaves as though it has a ‘skin’ on its surface.
  • When separate streams of water flow, each has its own surface ‘skin’.
  • If these streams are made to touch each other, their surfaces join up to make one combined surface.
  • This ‘skin-like’ quality at the water’s surface is called ‘surface tension’.
  • Surface tension makes water cling to itself.
  • When streams of water come into contact with each other they combine to give the smallest overall surface.
  • Disturbing the combined stream can recreate the separate streams.
