A Tour of the Scratch Interface

Sprites, Backdrops, and the Stage

Your First Scratch Program — Make the Cat Move!

Quiz: Welcome to Scratch

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.

Moving with Motion Blocks

Turning and Pointing

Changing Costumes

Speech Bubbles and Thinking Bubbles

Size, Show, Hide, and Effects

Mini-Project: Animated Greeting Card

Quiz: Motion and Looks

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.

What Is a Sequence?

The Forever Loop

The Repeat Loop

The Wait Block and Timing

Nesting Loops (Loops Inside Loops)

Mini-Project: Looping Animation Scene

Quiz: Loops and Sequences

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.

Touching Color and Sprite Collision

Asking the User a Question

Quiz: Conditionals and User Input

Build a Keyboard-Controlled Maze Game

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.

Building a Score Counter

Building a Countdown Timer

Math Operators (+, −, ×, ÷)

Comparison and Logic Operators

Mini-Project: Catch the Falling Stars (Score + Timer)

Quiz: Variables and Operators

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.

Broadcast — Sending Messages

Broadcast and Wait

Switching Scenes with Backdrops and Broadcasts

Mini-Project: Multi-Scene Story

Quiz: Events and Messages

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.

Volume and Stop Sound

set volume to (100)% — sets the volume (0 = silent, 100 = full).
change volume by (-10) — gradually fades volume up or down.
stop all sounds — stops every sound currently playing.

Fade-Out Effect

repeat (10) → change volume by (-10) → wait (0.1) seconds

This reduces volume from 100% to 0% over 1 second, creating a smooth fade-out.
