  • 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.
