Product Description
Video and lesson investigations on the topic of inflatables and compressed air. Key concepts include:
- Containers made from ‘flexible’ or ‘elastic’ material inflate when air is pumped into them.
- ‘Inflatables’ is a term used to describe such containers.
- Air takes the shape of the container that encloses it.
- Bounce depends upon the shape of the container, the amount of air inside it and the material it is made from.
- Bounce happens when the air inside is suddenly compressed, briefly distorting the shape of the container. The container reacts by quickly returning to its inflated shape.
- The mixture of gases which make up air push against the walls of any container filled with air.
- When the air-filled container is a flexible one, the pushing of the air from the inside gives the container a bouncy quality.
