Activities \| Wireless but not clueless

Uniserve Science (Australia)
- Radio and television – students learn how the modulation of amplitude or frequency of visible light, microwaves and radio waves can be used to transmit information.
- The electromagnetic spectrum – students use the internet to find out how modern communication technology works.
- The digital age – students look at the development of digital technology and how it has become the core of modern communications.
Science Netlinks (American Association for the Advancement of Science, USA)
- Communications technologies – students explore how technology has increased the ways in which people communicate.
Public Broadcasting Service (USA)
- Inventing the future teaching guide: Private eyes – students investigate issues about computer technology and artificial intelligence by participating in a debate.
Science and Technology in Action (UK)
