Mobile Phones – How much do you know? (KS3/4)

Students learn about the invention of smartphones from Alexander Graham Bell to the 5G. Find out when they were invented, how they work and safety tips.

With thought provoking facts and figures to stimulate discussion this 30-minute lesson is linked to the KS3 and KS4 computing, computer science and design & technology curriculum and looks at three key areas:

  • Mobile phone history
    Starting from the invention of telephones in 1985 by Alexander Graham Bell, the lesson traces the history of the development of mobile phones to the current time.
  • How mobile phones work
    The lesson covers ARM microprocessors, phone design and smartphones.
    Network generations from 1G to 5G are briefly explained.
  • Staying safe on your mobile phone

Many of these developments are illustrated by life stories taken from the Archives of IT website. Accompanying teachers’ notes are also available.
