Build and Share a Scratch Game

This unit guides students through completing a playable Scratch robot-and-asteroid project: translating flowcharts into code, creating sprites and backdrops, implementing variables and controls, adding sound, and polishing the user interface. It also teaches testing, debugging, saving, publishing, and pathways for extending projects to hardware or other platforms to prepare learners for further study or real-world applications.

Learning Objectives

• Analyze flowcharts and project requirements to translate program logic into Scratch event-driven scripts and control flow sequences.
• Apply programming constructs — sprites, backdrops, variables (e.g., dents and timer), loops, and keyboard controls — to implement a complete interactive robot-asteroid game.
• Demonstrate testing, debugging, and versioning practices by identifying and fixing defects, documenting test cases, and saving and publishing a working Scratch project.
• Evaluate user experience and functionality by iterating on the interface, adding sound/music and enhancements, and proposing at least one method to extend the project to physical devices or external platforms.
