This magic trick from the Computer Science for Fun (CS4FN) team at QMUL is based on a ‘self-working trick’. It includes a set of instructions which, so long as the commands are followed, works every time. It is, therefore, an algorithm.

The trick involves playing cards – the actual value of the cards is not...

Artificial intelligence (AI) is a disruptive technology, meaning that it is significantly changing the way that people, businesses, and industry interact. To put it in context, the invention of the wheel, electricity, TV, and GPS are all disruptive technologies that changed the way in which society worked.

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

This activity from the CS4FN team at QMUL is a metaphorical introduction to Human-Computer Interaction (HCI), graphical user interfaces (GUIs) and the difficulties of working at the command line.

The whole-class activity uses a game called spit-not-so. The winner of the game is the first to choose, from a...

Using a set of simple ‘swap puzzles’, this CS4FN activity helps students to learn, fundamentally, what an algorithm is and how they can be made more efficient. Students are encouraged to create algorithms for solving the puzzles which can be used by future players to win, with no understanding of the game, in as...

In this activity students explore why a water clock was the world's first programmable system. Programmable systems are by no means a modern invention. Many regard the first to be Ktesibios's water clock, which was invented approximately 2250 years ago.

The aim of this activity is that students apply what...

This unplugged activity from the CS4FN team uses two examples – an insulting computer and one that can play snap – to look at simple computer programming, flow of control and logic. Everything is provided for this front-of-class activity, which would act as an effective starter for a lesson on programming concepts...

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...

This engineering activity, suitable for children in computing lessons, looks at the basics of flowchart construction. Simple examples, such as the decisions made by a dog chasing a stick, are used to make flowchart representation of algorithms accessible to younger children. A simple design activity requires...
