Scratch is an educational programming language and multimedia tool that allows students, teachers, and parents to create a variety of projects for education and entertainment, such as math and science simulations, recordings of lectures with animations, interactive stories in social sciences, and art and music. The name "Scratch" refers to the ease of mixing different projects, like how DJs can easily mix sounds, as the tool was created by the Lifelong Kindergarten group at MIT in 2003 to be accessible for learners of all ages.
