The Stage is where the action takes place in your project. The Stage has one or more background images called backdrops.

Sprites are characters and objects that appear on the Stage. Sprites are given instructions using Scratch code blocks. This is called programming.

Drag code blocks from the Blocks menu to the Code area to program your sprites and the Stage. Code blocks can make a sprite move around, change the way that it looks, and play sounds.

Sprites can have multiple costumes. You can change the costume to change the appearance of a sprite. This can be used for effects such as giving the appearance of walking.

A script is a series of blocks that are joined together to give instructions to the Stage or sprites. The Stage and sprites can each have many different scripts.
