  • Space debris is leftover rocket parts and non-functional satellites and any other machinery or debris left by humans. Humans have been launching rockets into space since the 1950s, and now, 70 years later, there is a vast amount of non-functional space junk circling around the Earth.

    In this activity, students consolidate their learning about space debris by creating an interactive model or game in Scratch.

    By the end of this activity, students should be able to:

    • share a digital outcome with an end user
    • explain how their digital outcome models aspects of the issue of space debris
    • explain how algorithms are used in their digital outcome work.

    During this activity, students will produce a game or interactive model using Scratch. They will make choices about the visual design and how they are going to represent the issue of space debris and publish a completed digital outcome for others to use. Students will need to test their code from time to time and make adjustments as necessary.

    Two Scratch games are available to share with students so they can conceptualise the kind of outcome expected. Teachers do not need to be experts in using Scratch. Their role is to introduce the issues of space debris, provide the parameters of the finished digital outcome and support students to problem solve their own solutions.
