Scratch Jr Project Idea: Build a Virtual Piano

What a fantastic idea! Building a virtual piano with Scratch Jr is a great way to introduce young learners to the world of coding and music. Here's a project idea to get you started:

Project Title: "Piano Palooza"

Objective: Create a virtual piano that allows users to play different notes and sounds using Scratch Jr programming.

Materials:

• A tablet or computer with Scratch Jr installed
• A set of blocks (optional, but fun for kids to build)

Step-by-Step Guide:

1. Create the Stage: Open Scratch Jr and create a new project. Name it "Piano Palooza." Set the stage size to 480x360 pixels.
2. Add the Piano Keys: Use the paint tool to draw a grid of rectangles on the stage, representing the piano keys. You can use different colors for each key or keep them all white.
3. Create the Note Blocks: Create separate blocks for each note (A, B, C, D, E, F, G). Each block should play a specific sound when clicked.
4. Add Sound Effects: Use the "Sound" tool to add sound effects for each note. You can find plenty of free piano sounds online or record your own.
5. Create a Piano Keyboard Script: Write a script that allows users to press the notes to play the corresponding sounds. For example:
   • When the user clicks on a C key, the script will say "C" and play the C sound effect.
6. Add Octaves and Sharps: Expand your virtual piano by adding octaves (higher or lower pitches) and sharps (#). You can create separate blocks for each octave and sharp.
7. Add Visual Feedback: Use visual effects like flashing lights, shapes, or animations to provide feedback when a note is played.
8. Test and Refine: Test your virtual piano by clicking on the notes and listening to the sounds. Make adjustments as needed to ensure the sounds are playing correctly.

Tips and Variations:

• Add more complexity by introducing dynamics (volume control), articulation (legato, staccato), or even harmonies.
• Create a "Compose" mode where users can create their own melodies using the virtual piano.
• Incorporate math concepts by having the user input numbers to generate a random melody.
• Use this project as a starting point and build more complex instruments like a drum set or synthesizer.

Assessment Ideas:

1. Ask students to demonstrate how they used Scratch Jr programming to create their virtual piano.
2. Have them test and troubleshoot their project, identifying and fixing any errors.
3. Evaluate the creativity and complexity of their instrument, encouraging them to think about how they can add more features or improve the overall user experience.

Extension Ideas:

1. Create a "Piano Palooza" app with a simple user interface that allows users to play the virtual piano without needing to know how to code.
2. Collaborate with students from different schools to create a global "Piano Palooza" project, where they can share and learn from each other's creations.
3. Explore more advanced concepts like conditional statements, loops, or variables by adding additional features to the virtual piano.

This project is an excellent way to introduce young learners to coding, music, and creativity. With Scratch Jr, they'll develop essential skills in problem-solving, critical thinking, and collaboration while having fun building their own virtual instruments!
