We are working towards a project like Caesar Cipher on Scratch because it neatly explains how algorithms are used to make programs – but first we need a heap of other skills. Backgrounds are one of them.

For today’s task, create a button that changes the background. If you want to see how it is done first, check this out. Otherwise feel free to have a play around (or Google ‘how to make a button scratch’, ‘how to change the background scratch’, etc.).

NB: If you want to jump ahead and create a Cipher like the one above, go ahead! It can’t hurt…
