Scratch

Participants build something that actually runs, usually within the first twenty minutes. Scratch works by dragging blocks together instead of typing code, so there’s no syntax to get wrong and no waiting to be told the right way to do it. We start with a short guided build, make the cat move, make it say something, make it react, and then people take it wherever they want: a game, an animation, a story, or a running joke about their mate.

The session covers the ideas that sit under all programming (loops, events, conditions, cause and effect), but we introduce them as things people want to do rather than concepts to learn. Most of the time is spent trying something, watching it go wrong, and working out why, which is the actual skill. Everyone finishes with a saved, working project they can show someone and carry on with at home.

It gives people a real taste of how code works (loops, events, cause and effect) without the barrier of typing syntax, so mistakes are easy to spot and fix. Because everyone leaves with their own finished animation or game, it builds confidence as well as understanding. Scratch is also free and runs in a browser, so there’s nothing to buy and no reason the interest has to stop when the session ends.
