Product Description
Video and lesson investigations on the topic of surface tension. Key concepts include:
- The surface of water behaves as if it has a ‘skin’.
- This ‘skin’ is strong enough to support light objects.
- Some creatures are light enough to rest on the surface of water.
- These creatures have adapted to a lifestyle which involves them making use of the surface of water.
- Surface tension is strong enough to support creatures which have evolved ways of using the water-surface environment to suit the way in which they live.
