In this activity, students conduct a few simple activities to learn more about surface tension – a liquid’s thin ‘skin’.

By the end of this activity, students should be able to:

  • talk about water molecules and the way in which they are attracted to each other
  • talk about how the various activities demonstrate surface tension
  • use equipment in a consistent manner.
