When we click '''Create''' on the Scratch home page a project creation window opens. The project window consists of several items. The grey bar at the top contains a menu. On the left there is a stage on which sprites perform scripts. Underneath there is a sprite panel.

=== Web browser Scratch 2.0 environment – the stage ===
The stage is a window in which the project is implemented. This is where sprites execute scripts.

=== Web browser Scratch 2.0 environment – the sprite panel ===
The sprite panel contains information on all sprites placed in the project. Here we can create a new sprite. We can also select (click) the stage and set its background.

When we click the blue circle with the letter “i” in the upper left hand corner of the sprite image we can see information about the sprite’s properties:<br />
• rotation style:in a circle – that is any rotation, horizontally – rotation only to the right and to the left dot – no rotation<br />
• can drag in player – when we select the square we will be able to drag the sprite with the maximized stage site (i.e. in the player)<br />
• show – after unchecking the square the sprite will be hidden (the same is done by the hide block)<br />
=== Web browser Scratch 2.0 environment – the resource panel ===
In the new Scratch version (2.0) there are 10 groups of blocks with which we build sprite scripts. Each sprite may have different scripts. Scripts are built by dragging blocks from the '''tray''' to the right side – to the '''scripts window'''. A block can be removed by dragging it outside this window. A block can be made by clicking on it both in the tray and in the scripts window. A block or script being executed has a yellow border. Some blocks have windows which can be filled in (with numbers, text, or by selecting values).
