Encryption
In this computer science lesson students are introduced to encryption. They model the way that information is transmitted by the internet and try and protect their messages using different keys. Light - there's more to it than meets to the eye. Data from one computer is converted into super-fast pulses of light which can be sent down optical fibres to others all around the world. However, information sent via the internet is at risk from eavesdroppers - how can science help keep our secrets?
