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.
