The Scratch patch - substitution cipher

This project, exploring basic encryption, is a useful introduction to data security as well as iterating through strings to manipulate them. The program create a ‘substitution cipher’, one of the most basic forms of encryption. It also demonstrates that, for more complex chained commands, Scratch becomes rather...

The Scratch patch - error handling

This activity is an introduction to writing programs that can handle errors. It also helps students to understand number bases, by guiding them through the writing of a ‘base converter’ program.

Curiosity's Seven Minutes of Terror

In August 2012, an unmanned rover touched down on the surface of Mars. NASA's Curiosity Rover was sent to take measurements of the atmosphere and martian terrain in an effort to understand more about the history of Mars and whether the planet ever sustained life. This video shows an animation of the incredible...

Java programming with Greenfoot: viewer questions (timers)

This video tutorial considers how to arrange for something to happen after a specific time delay.  It covers the difference between real time and game time; the latter depends upon the program’s frame rate, which can be quickly altered by the speed setting within the game.  Expressing changes in real time is...

Java programming with Greenfoot: refactoring for good style (teacher commentary)

This video explains good coding behaviour.  This includes an emphasis on refactoring (changing code to make its structure better so that it can later be easily changed or understood) and cohesion (ensuring that each method does only one thing).  It also explains that private methods will only apply to objects in...
