Inputs outputs
  • Modems Unplugged: this activity requires students to listen to songs and find the hidden messages based on the same principle as a modem. CS Unplugged
  • Error Detection: this lesson demonstrates to students how transmitting data from one computer to another can change the information. This activity shows how to detect when data has been corrupted and how to correct it. CS Unplugged
  • What are input and output devices?: use these interactive resources to support students with learning about digital systems. BBC Bitesize
  • How computers work: the purpose of this activity is to give students a sense of how computers work through role play. Students form small groups and each have a role to play as different parts of a computer. Gary Kacmarcik


  • Inside your computer: use this video to help students to understand how digital devices work around them. As an extension, ask your students to find a way to explain what they have learnt to somebody else, including making their own video, animation, writing a blog, writing a report, or creating a drawing. TedEd Talk by Bettina Bair

  • Inputs and Outputs: Watch students who have made their own video to explain inputs and outputs. Get your students to creative their own video, story or animation to explain the difference between an input and output device. Students at Bush Elementary

Ideas to try

Connect computers
  • Create a glossary: integrate digital technologies terms and concepts into a student created glossary. This supports students to become familiar with the language of the learning area. During lessons, make explicit use of the Digital Technologies terms, reinforcing students’ knowledge about what they mean and how they are used in particular contexts. Create a Word Wall where students add Digital Technology terms as they learn them.
  • Put the computer together: unplug your desktop computer and peripheral devices, including the mouse, keyboard, speakers, and printer and tell students to work as a team to connect it back together. Please note that the power should not be connected by a student. They may need to research what the different plugs are for. It may be helpful to label the different cords with their name, including VGA plug, USB plug. Remind students that they should not connect it to power without adult supervision.



  • Old computers.
  • Bee-bot or other types of robots.
  • Games consoles, new or old, which students can experiment with to explore how they work.
  • Dot and Dash Robots (paid, programmable robots): these robots can be programmed using an iPad or Android device. The robots can do anything a student can set their mind to. Complete with lesson plans for teachers.
  • Kano computer kit (paid, computer kit): kits where students build their own computer from scratch and learn about the different parts of a computer. They are then able to build, program and code various games, interactive etc. using their new device. It is designed like Lego to enable students as young as 6 to be able to follow the directions. Suitable for ages 6-12.
