Basic Elements of the Scratch window

Sprite:

In Scratch, we work with objects called sprites.

Sprites are placed on the stage.

We can select a sprite from the sprite library or create a new sprite.

Stage :

The stage is the area where we can see the sprite in action. The sprite’s movement and other actions are controlled by instruction blocks.

Script area

It is the area where we create our scripts or programs for each sprite by stacking various instruction blocks in a sequence.

Block palette

The blocks palette contains all instruction blocks that are grouped according to their functions.
