Content:

The 3S of Scratch:

1. Sprite: Characters or objects that perform actions in Scratch projects.
2. Script: Code blocks that provide instructions to sprites.
3. Stage: The area where the project is displayed and sprites perform actions.

Component Parts of the Scratch Interface:

1. Block Palette: Contains code blocks for creating scripts.
2. Script Area: Where code blocks are assembled to create scripts.
3. Sprite List: Displays all the sprites in the project.
4. Stage: Shows the project output.
5. Costume Tab: Allows changes to the appearance of sprites.
6. Sound Tab: Manages sounds for sprites.

Scratch Programming

The 3 S’s of Scratch

1. Stage
   • The area where your project is displayed.
   • Example: Think of it like a stage in a theatre where actors perform.
   • 🖼️
2. Sprites
   • The characters or objects in your project.
   • Example: A cat sprite that moves across the stage.
   • 🐱
3. Scripts
   • The code blocks that control the sprites.
   • Example: A script to make the cat sprite move 10 steps.
   • 🧩

Component Parts of the Scratch Interface

1. Toolbar
   • Contains tools to create and manage your projects.
   • Example: Save, load, or start a new project.
   • 🛠️
2. Block Palette
   • Where you find the blocks to build scripts.
   • Example: Motion, looks, and sound blocks.
   • 🟦
3. Script Area
   • The space where you drag and drop blocks to create scripts.
   • Example: Drag a “move 10 steps” block into the script area.
   • 📜
4. Sprite List
   • Shows all the sprites in your project.
   • Example: A list with the cat sprite, a ball sprite, etc.
   • 📃
5. Stage
   • Displays the project as it runs.
   • Example: Watch your sprite move and interact here.
   • 🎬
6. Costume Tab
   • Change the appearance of sprites.
   • Example: Switch the cat sprite’s costume to make it look like it’s walking.
   • 👗
7. Sound Tab
   • Add and manage sounds for sprites.
   • Example: Add a meow sound for the cat sprite.
   • 🎵

Examples in Action

• Move Sprite: Drag a “move 10 steps” block to the script area to see the sprite move on the stage.
• Change Costume: Use the costume tab to switch between different looks for your sprite.
• Play Sound: Add a “play sound” block from the sound tab to hear the sprite make noise.
