CONTENT OF THE LESSON

INTRODUCTION

When using Scratch, different parts of the screen help users create programs, control sprites, and test their projects. These parts together form the Scratch interface.

In this lesson, pupils will learn the meaning of Scratch programming, the Scratch interface, and the component parts of the Scratch interface and their functions.

LESSON 1 – MEANING OF SCRATCH PROGRAMMING

Scratch programming is the process of creating computer programs by dragging and dropping coding blocks instead of typing commands.

Scratch is a visual-based programming language developed by the Massachusetts Institute of Technology (MIT) to help children learn coding in a simple and enjoyable way.

MEANING OF THE SCRATCH INTERFACE

The Scratch interface is the working environment or screen where users create, edit, and run Scratch projects.

It contains different sections that help users build programs easily.

COMPONENT PARTS OF THE SCRATCH INTERFACE

1. Menu Bar – The Menu Bar contains options for creating, opening, saving, and managing Scratch projects.

2. Toolbar – The Toolbar contains useful tools and buttons for working on Scratch projects.

3. Stage – The Stage is the area where sprites perform the instructions given to them. It is where the animation or program is displayed.

4. Sprite List – The Sprite List displays all the sprites available in the current project.

5. Sprite Pane – The Sprite Pane shows information about the selected sprite, such as its name, size, and position.

6. Blocks Palette – The Blocks Palette contains different coding blocks grouped into categories such as Motion, Looks, Sound, Events, Control, and Sensing.

7. Coding Area (Scripts Area) – The Coding Area is where coding blocks are dragged and joined together to create programs.

8. Tabs – Scratch has three main tabs:

• Code Tab – Used for writing programs with coding blocks.

• Costumes Tab – Used for changing or editing the appearance of a sprite.

• Sounds Tab – Used for adding or editing sounds.

9. Green Flag – The Green Flag starts or runs the Scratch program.

10. Stop Button – The Stop Button stops the Scratch program.

11. Backdrop Area – The Backdrop Area is used to select or change the background of the Stage.

LESSON 2 AND LESSON 3 – PRACTICAL DEMONSTRATION (HAND ON ACTIVITIES)

The teacher demonstrates the following practical activities using the Scratch application:

1. Open the Scratch application on the computer.

2. Identify the Menu Bar and Toolbar.

3. Locate the Stage and explain that it is where sprites perform their actions.

4. Identify the Sprite List and select a sprite.

5. Show the Blocks Palette and explain the different categories of coding blocks.

6. Drag a Motion block into the Coding Area (Scripts Area).

7. Join another block to create a simple program.

8. Click the Green Flag to run the program and observe the sprite move on the Stage.

9. Click the Stop Button to stop the program.

10. Click the Costumes Tab and change the appearance of the selected sprite.

11. Click the Sounds Tab and add or play a sound for the sprite.

12. Change the Backdrop of the Stage using the Backdrop Area.

13. Save the Scratch project with a suitable file name.

PUPIL’S ACTIVITIES

1. Open the Scratch application.

2. Identify each component of the Scratch interface.

3. Drag and join coding blocks in the Coding Area.

4. Run the program using the Green Flag.
