Using Speech Bubbles to Explain a Character's Feelings: Computer Science Lesson for K-5

📚 Learning Objective

Students will be able to use speech bubbles in a visual programming environment (Scratch) to represent a character's feelings, demonstrating an understanding of basic emotional representation in computer science.

🍎 Materials

• 💻 Each student or pair of students will need a computer with internet access to use Scratch (scratch.mit.edu).
• 🖍️ Paper and crayons or colored pencils for initial brainstorming and sketching.
• 🎭 Pre-made character sprites in Scratch (optional, students can also create their own).
• 💬 List of feelings vocabulary words (e.g., happy, sad, angry, surprised, scared).

👋 Warm-up (5 minutes)

Emotion Charades: Act out different emotions and have students guess what you are feeling. Discuss how we can tell what someone is feeling by looking at their face and body language.

💻 Main Instruction (25 minutes)

1. Introduction to Speech Bubbles (5 mins):
   • 🗣️ Explain what speech bubbles are and where we usually see them (e.g., comic books).
   • 🤔 Ask: "Why do authors use speech bubbles?" (To show what characters are saying or thinking).
   • 🎨 Discuss how different shapes or colors of speech bubbles might represent different feelings (e.g., jagged bubbles for anger).
2. Scratch Demonstration (10 mins):
   • 🐱 Open Scratch and show students how to add a character sprite.
   • ⚙️ Demonstrate how to use the "say" block to make the character speak. (The "say" block is found under the "Looks" category).
   • ✏️ Show them how to change the text inside the "say" block.
3. Activity: Feeling Bubbles (10 mins):
   • 😃 Give students a scenario (e.g., "Your character just won a game!").
   • ✍️ Have them write down what their character might say or think if they were feeling that emotion.
   • 💡 Have them use the "say" block to make their character express the feeling in Scratch.

🧪 Extension Activities

• 🎭 Use different character sprites and have students create a short dialogue between two characters using speech bubbles.
• 🎨 Have students design their own custom speech bubble shapes to represent different emotions.
• ✍️ Write a short story where the characters' feelings are only revealed through their speech bubbles.

✅ Assessment

• 📝 Observe students as they create their feeling bubbles in Scratch.
• 🗣️ Ask students to explain why they chose certain words to represent a particular emotion.
• ⭐ Review their Scratch projects to ensure they are using the "say" block correctly and effectively.
