- To know how infrared waves transmit data
Pupils should be taught to:
- Understand computer networks including the internet; how they can provide multiple services, such as the world-wide web; and the opportunities they offer for communication and collaboration
Pupils needing extra support: Enable these children to use the most user-friendly cameras/devices, or to bring devices which they are familiar with. Encourage them to take a video rather than trying to capture a photo.
Pupils working at greater depth: Children may even be able to recognise that each button on the device will transmit a slightly different sequence of flashes, like a binary/Boolean signal.
