Course Content
Welcome to Scratch
Students get oriented with the Scratch platform, understand what programming is, and set up their free Scratch account ready for the rest of the course.
0/6
Motion and Looks
Students learn to move sprites around the Stage using Motion blocks, and change how sprites look using Looks blocks — including costumes, speech bubbles, and size changes.
0/7
Loops and Sequences
Students learn to repeat actions efficiently using loop blocks (forever, repeat, repeat until) and understand how the order of blocks in a sequence changes the program's behaviour.
0/7
Conditionals and User Input
Students learn to make programs that react and make decisions using if/else blocks, key-press detection, and mouse input — the foundation of interactive games and apps.
0/8
Variables and Operators
Students learn to store and manipulate data using variables, and combine values with math and logic operators — the tools needed to build scoreboards, timers, and smarter programs.
0/7
Events and Messages
Students learn how Scratch programs react to events (flag click, key press, sprite click) and how sprites communicate with each other using broadcast messages.
0/7
Sound and Music
Students add sound effects and music to their projects using Scratch's Sound editor and blocks, making their games and animations more engaging and polished.
0/8
Lists and Clones
Students learn to store multiple values in lists, and to create multiple copies of a sprite using clones — two powerful tools for building more complex and dynamic projects.
0/7
Final Project and Course Wrap-Up
Students apply every skill learned in the course to build and present a complete Scratch game or interactive project — their portfolio showpiece. The topic closes with a review of key concepts and guidance for continuing to grow as a programmer.

Programming with Scratch: Build Games & Animations from Zero (Copy 1)

Changing Costumes

A costume is a different look for the same sprite. Switching costumes creates animation.

 

How to Switch Costumes

  • switch costume to (name) — jumps directly to a specific costume.
  • next costume — cycles to the next costume in the list.

 

Creating a Walking Animation

  1. Select the Scratch Cat — it already has two costumes (costume1, costume2).
  2. Build: When 🏁 clicked → forever → next costume → wait (0.2) seconds → move (10) steps.
  3. Run — the cat walks with animated legs!
