Card Flip Magic - Error Detection

When data is stored on a disk or transmitted from one computer to another, it is usually assumed that it doesn’t get changed in the process. But sometimes things go wrong and the data is changed accidentally. This activity uses a magic trick to show how to detect when data has been corrupted, and how to correct it. The resource begins by explaining how to perform the trick and suggestions as to how the trick can be taught to students. There are also extension activities. There follows a real-life example using ISBN numbers. To conclude there is more information about error detection followed by solutions and hints. This collection of twenty activities from Computer Science Unplugged is designed to aid the teaching and learning of computer science through engaging games and puzzles using cards, string, crayons and lots of running around.
