Activity overview

An Unusual Discovery

Two characters meet in a world and discover a surprising object. What happens next? Students create an interactive story using code by programming dialogue and animating interactions between characters and their surroundings.

The activity uses Scratch 3.0, a new and improved version of the Scratch tool that features new design libraries, functionality on different devices and many more fun tools. Learn more about Hour of Code and Scratch 3.0.
