Makey Makey arcade
Hold the earth strip and touch a foil input. Predict which part of the game will change.
In this unit, students for Grades 6–8 design and build their own arcade games using Makey Makey and Scratch. They begin by exploring circuits, switches, and how Makey Makey works, then use mind mapping to develop their ideas. Students create ideation sketches, use a decision matrix to select their best design, and prototype a small part of their arcade machine with foil and cardboard before building the full version. Throughout, they document their thinking and test their prototypes to solve the design challenge of creating a working arcade game.
