Use Scratch to code an interactive Harry Potter inspired story with sprites, dialogue, simple animations, and sound effects while learning sequencing and events.


Step-by-step guide to code a Harry Potter-inspired story in Scratch
Step 1
Open Scratch and create a new project to start your Harry Potter inspired story.
Step 2
Write a short story plan with a beginning a middle an end and one choice that the player can make.
Step 3
Pick three sprites to be your characters for the story like a young wizard a friend and a mysterious character.
Step 4
Choose two backgrounds for two different locations in your story like a castle hallway and a spooky forest.
Step 5
Give each main sprite at least one extra costume so they can change expressions or pose for simple animation.
Step 6
Add at least three sound effects to your project for spells footsteps and magical whooshes.
Step 7
Create a start script that runs when the green flag is clicked and sets the starting backdrop and shows your main sprite on stage.
Step 8
Program the main sprite to say its first lines using say and wait blocks and then broadcast a message to continue the story.
Step 9
Program the other sprites to listen for that broadcast and respond with their own say blocks or actions.
Step 10
Add animations and sounds by coding scripts that change costumes glide or play sounds when broadcasts happen.
Step 11
Make one interactive choice by adding a button sprite or using an ask block and broadcast different messages for each player choice.
Step 12
Test your interactive story by clicking the green flag and trying each choice then tweak the timing positions and text until it feels right.
Step 13
Save your project give it a clear title and write short playing instructions in the project notes.
Step 14
Share your finished Harry Potter inspired interactive story on DIY.org
Final steps
You're almost there! Complete all the steps, bring your creation to life, post it, and conquer the challenge!

Help!?
What can we do if we can't access the Scratch website or can't find a castle/forest backdrop or good sound effects?
Use the Scratch Desktop app if you can't access the website, draw your own castle and spooky forest in the Backdrop editor, and replace missing sounds by importing short recordings from a phone into the project's Sounds tab or using built‑in library sounds.
My broadcasts don't seem to trigger the other sprites or the sounds cut off—what should I check?
Make sure the broadcast names match exactly and each listener sprite has a matching 'when I receive [message]' block, add 'show' and 'switch backdrop to' in your start script, and insert 'wait' or use 'play sound until done' between 'say' and 'broadcast' so animations and sounds can finish.
How can I adjust the project for younger kids or make it more challenging for older kids?
For younger kids simplify the story plan to a beginning and end, use two sprites and a single button sprite for the choice, and for older kids add extra costumes, multiple broadcasts for branching choices, variables to track decisions, and more complex animations like glide and clones.
What are easy ways to extend or personalize the Harry Potter inspired story after the basic version works?
Personalize it by recording your own spoken lines and spell sounds in the Sounds tab, add extra costume changes and glide paths for richer animation, create multiple endings tied to different broadcasts, and write clear playing instructions and credits in the project notes before sharing on DIY.org.

Facts about Scratch programming for kids
⚡ Event-driven blocks like "when green flag clicked" let you control sequencing and trigger actions for interactive stories.
🧩 In Scratch, characters are called "sprites" and each sprite can have costumes, sounds, and its own scripts.
🖥️ Scratch was created at MIT and first released in 2007 to teach kids coding with colorful blocks.
🎵 You can add built-in sounds or record your own voice in Scratch to bring dialogue and effects to life.
🧙♂️ The Harry Potter book series has sold over 500 million copies worldwide — full of ideas for magical scenes!
