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)

If/Else — Two Paths

The if/else block runs one set of blocks when the condition is true and a different set when it is false.

 

Example: Day/Night

  1. if then
  2. switch backdrop to (sunny day)
  3. else
  4. switch backdrop to (night sky)

Only one of the two backdrops ever shows — never both at the same time.

 

When to Use If vs If/Else

  • Use if when you only need something to happen in one case.
  • Use if/else when you need two different reactions.
