CONTENT OF THE LESSON

INTRODUCTION

Scratch is a visual programming language that allows users to create interactive stories and conversations. By combining different programming blocks, sprites can greet one another, ask and answer questions, and perform actions just like people in real life.

In this lesson, pupils will learn how to use Scratch programming to create a simple conversation between two friends, helping them improve their programming, communication, and creative thinking skills.

LESSON 1 – MEANING OF A CONVERSATION IN SCRATCH

A conversation in Scratch is the process of using sprites and programming blocks to make two or more characters talk to one another on the Stage. The conversation is created by arranging blocks that display messages, wait for a short time, and allow each sprite to speak in turn.

Scratch makes it easy to create interactive conversations without typing complex computer code.

SCRATCH BLOCKS USED TO CREATE A CONVERSATION

The following Scratch blocks are commonly used to create a conversation between friends:

1. Events Blocks

These blocks start the program.

Example: When Green Flag Clicked

2. Looks Blocks

These blocks display speech or thought messages.

Examples:

• Say [Hello!] for 2 seconds

• Think [I am happy.] for 2 seconds

3. Control Blocks

These blocks control the timing of the conversation.

Examples:

• Wait (1) seconds

• Forever

• Repeat

4. Motion Blocks

These blocks move the sprites during the conversation.

Examples:

• Move 10 steps

• Glide to position

• Turn 15 degrees

LESSON 2 – STEPS FOR CREATING A CONVERSATION BETWEEN FRIENDS

1. Open Scratch 3.0.

2. Create a new project.

3. Choose two sprites.

4. Add the When Green Flag Clicked block to each sprite.

5. Add Say blocks to display each character’s dialogue.

6. Use Wait blocks to allow one sprite to speak before the other replies.

7. Add Motion blocks if the sprites need to move.

8. Click the Green Flag to run the conversation.

9. Save the completed Scratch project.

EXAMPLE OF A SIMPLE CONVERSATION

Friend 1: Hello! How are you?

Friend 2: I am fine. Thank you.

Friend 1: Are you coming to school tomorrow?

Friend 2: Yes, I will be there. See you tomorrow!

SUMMARY

In this lesson, pupils learned that a conversation in Scratch is the process of using sprites and programming blocks to make two or more characters talk to one another on the Stage. They learned that Scratch can be used to create interactive stories and conversations in a simple and enjoyable way.

Pupils identified the Scratch blocks used to create conversations, including the Events block (When Green Flag Clicked) to start the program, the Looks blocks (Say and Think) to display messages, the Control block (Wait) to control the timing of the conversation, and the Motion blocks to move the sprites.

Furthermore, pupils learned the steps involved in creating a simple conversation between two friends by selecting sprites, adding dialogue with the Say block, using the Wait block for timing, and running the program with the Green Flag.

Finally, pupils discovered that creating conversations in Scratch helps to develop programming skills, communication skills, creativity, logical thinking, and problem-solving skills, while enabling them to create interactive stories, animations, and educational projects.

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

Step 1: Introduction – The teacher asks pupils if they have ever watched a cartoon or animation where two characters talk to each other. The teacher explains that Scratch can be used to create a conversation between two friends using programming blocks.

Pupils’ Activities: Pupils mention cartoons or animations they have watched and listen attentively to the teacher’s explanation.

Step 2: Meaning of a Conversation in Scratch – The teacher explains that a conversation in Scratch is the process of using sprites and programming blocks to make two or more characters talk to one another on the Stage.

Step 3: Scratch Blocks Used for Creating a Conversation – The teacher introduces the Scratch blocks used to create a conversation, including:

• Events block (When Green Flag Clicked)

• Looks blocks (Say and Think)

• Control block (Wait)

• Motion blocks

The teacher explains the function of each block.

Pupils’ Activities: Pupils identify the Scratch blocks used to create a conversation and state their functions.

Step 4: Creating a Simple Conversation – The teacher demonstrates how to:

• Select two sprites.

• Add the When Green Flag Clicked block.

• Use the Say block to display messages.

• Add the Wait block to control the timing.

• Use Motion blocks to move the sprites if necessary.

Pupils’ Activities: Pupils identify the steps involved in creating a simple conversation between two sprites.

Step 5: Practical Demonstration – The teacher demonstrates how to:

• Create a new project.

• Select two sprites.

• Program a simple conversation between the sprites.

• Click the Green Flag to run the conversation.

• Save the completed Scratch project.

Pupils’ Activities: Pupils follow the demonstration by creating a simple conversation between two friends and saving their Scratch projects.

Step 6: Group Activity – The teacher divides the class into four groups and assigns the following activities:

• Group 1: Explain the meaning of a conversation in Scratch.

• Group 2: Identify the Scratch blocks used to create a conversation and state their functions.

• Group 3: Create a simple conversation between two friends using Scratch.

• Group 4: Demonstrate the conversation before the class and explain the steps used to create it.

Each group presents its work before the class.

Pupils’ Activities: Pupils discuss the assigned tasks, complete the activities, and present their work.

Step 7: Lesson Summary – The teacher reviews the meaning of a conversation in Scratch, the Scratch blocks used, and the steps involved in creating a conversation between two friends.

Pupils’ Activities: Pupils answer oral questions and summarise the lesson.

Step 8: Evaluation – The teacher asks oral, written, and practical questions to assess pupils’ understanding of creating a conversation between friends using Scratch programming.

Pupils’ Activities: Pupils answer the evaluation questions and demonstrate a simple conversation using Scratch.
