Scratch is a free visual programming language used to easily create animations, games, etc. It provides a stepping stone to the more advanced world of computer programming. It can also be used for a range of educational and entertainment constructionist purposes from math andscience projects, including simulations and visualizations of experiments, recording lectures with animated presentations, to social sciences animated stories, and interactive art and music. 

Scratch allows users to use event-driven programming with multiple active objects called sprites. Sprites can be drawn, as vector or bitmap graphics, from scratch in a simple editor that is part of Scratch, or can be imported from external sources, including webcams.

«Scratching» in the language of computer science means to reuse code that can be beneficial and effectively used for other purposes and easily combined, shared and adapted to new scenarios, which is a key feature in Scratch.
