**Course Title:** Introduction to Programming with Scratch **Section Title:** Costumes, Backdrops, and Sounds **Topic:** Create a story with multiple scenes using costumes, backdrops, and sounds.(Lab topic) **Objective:** By the end of this lab, you will be able to create a story with multiple scenes using costumes, backdrops, and sounds in Scratch. You will apply your knowledge of sprite costumes, backdrops, and sound effects to tell a narrative. **Materials:** * Scratch online account (scratch.mit.edu) * A computer or laptop with internet access * This lab activity guide **Storytelling with Scratch** Storytelling is an essential part of human communication, and Scratch provides a unique platform to tell stories through interactive animations and games. In this lab, you will create a story with multiple scenes using costumes, backdrops, and sounds. **Step 1: Plan Your Story** Before starting your project, take a few minutes to brainstorm and plan your story. Ask yourself: * What is the main theme or plot of my story? * Who are the main characters? * What are the key events or scenes in my story? * How can I use costumes, backdrops, and sound effects to enhance my story? Write down your ideas and sketch out rough storyboards. **Step 2: Create Your Characters and Costumes** In Scratch, you can create multiple costumes for your sprite to tell different scenes in your story. 1. Create a new sprite or use an existing one. 2. Click on the "Costumes" tab in the top menu bar. 3. Draw or upload multiple costumes for your sprite. Each costume should represent a different scene or action in your story. 4. Name each costume to keep track of your story scenes. **Step 3: Design Your Backdrops** Backdrops provide the setting for your story. Create multiple backdrops to represent different scenes or locations. 1. Click on the "Backdrops" tab in the top menu bar. 2. Draw or upload multiple backdrops for your project. Each backdrop should represent a different scene or location. 3. Name each backdrop to keep track of your story scenes. **Step 4: Add Sound Effects and Music** Sound effects and music can enhance the mood and atmosphere of your story. 1. Click on the "Sounds" tab in the top menu bar. 2. Click on "Add a Sound" and select a sound effect or music from the library or upload your own. 3. Use the "Sound" block to play your sound effects and music at specific points in your story. **Step 5: Create Your Story Script** Using your costumes, backdrops, and sound effects, create a script for your story. 1. Drag and drop the "Switch Costume" block to change your sprite's costume for each scene. 2. Use the "Switch Backdrop" block to change the backdrop for each scene. 3. Add sound effects and music to enhance the mood and atmosphere. 4. Use the "Wait" block to control the timing of your story. **Step 6: Test and Refine Your Story** Test your story by clicking on the green flag. Watch your story unfold, and make any necessary adjustments to the timing, costumes, or sound effects. **Tips and Variations** * Use the "Broadcast" block to coordinate actions between multiple sprites. * Experiment with different sound effects and music to create a unique atmosphere. * Use the "Repeat" block to repeat certain actions or scenes in your story. **What's Next?** After completing this lab, you will be ready to explore more advanced topics in programming with Scratch. In the next topic, we will cover "Introduction to sensing blocks: Detecting keyboard and mouse inputs" from the User Input and Sensing section. **External Resources:** * Scratch Online Tutorals: [https://scratch.mit.edu/teachers](https://scratch.mit.edu/teachers) * Scratch Forums: [https://scratch.mit.edu/discuss/](https://scratch.mit.edu/discuss/) **Leave a Comment or Ask for Help:** Have questions or want to share your story with the class?
