Product Description
Video and lesson investigations on the topic of surface tension. Key concepts include:
- Water clings to itself as if it has a ‘skin’.
- This ‘skin-like’ quality at the water’s surface is called ‘surface tension’.
- Surface tension is strong enough to support light objects placed on it.
- Surface tension happens because the water molecules are strongly attracted to each other, and have a tendency to stay together.
- This is why water forms globules or drops, flows in streams, and appears to have a ‘surface skin’ which can support light objects on its surface.
