How to add sound effects in ScratchJr for elementary school?

📚 What is ScratchJr?

ScratchJr is a visual programming language designed for young children (ages 5-7) to introduce them to the basics of coding. Developed by the DevTech Research Group at Tufts University, in collaboration with the Lifelong Kindergarten Group at the MIT Media Lab and the Playful Invention Company, ScratchJr lets kids create interactive stories and games by snapping together graphical programming blocks. It's available as a free app for tablets, making it accessible to many elementary school students.

📜 A Brief History of ScratchJr

ScratchJr emerged from the success of its predecessor, Scratch, a programming language designed for older kids. Recognizing the need for a simpler, tablet-friendly coding environment for younger children, the creators developed ScratchJr. It was launched in 2014 and quickly gained popularity in classrooms and homes worldwide.

✨ Key Principles of Adding Sound Effects in ScratchJr
