A helpful worksheet describes an interesting demonstration on the surface tension of water. Learners guess how many drops of water the heads side of a penny will hold. This resource does a great job of describing just how a penny can...

Young scientists explore the concept of surface tension at is applies to water. In this activity, learners use a dropper to place drops of water on a penny. Each group guesses how many drops a heads-up penny will hold, then conducts the...

Students experiment with the cohesion of water molecules. In this surface tension lesson, students estimate how many drops of water a full glass can take before overflowing. They watch a video that explains water molecules.
