• Script: Script is a collection of a number of stacked blocks. It gives stepwise instructions
to a sprite to do something on the stage. Script is actually a program which gives the
instructions in the form of blocks. A script must have at least two blocks.
• Backdrop: It is the background of the stage.
• Tabs: Scratch has mainly three tabs which are described below.
Code Tab: It contains block categories and the list of blocks
in a category. Some block categories are—Motion, Looks,
Sound, Pen, Events, Control, Sensing, Operators, Variables,
and My Blocks. All block categories are of different colours.
In Scratch, each block performs a task in a project. The blocks
connect to each other like a jigsaw puzzle and create scripts.
Costumes Tab: In this tab, you can add and make changes in
the appearance of the sprites and backdrops.
Sounds Tab: In this tab, you can add and make changes in
the sounds of the sprite and backdrop.
BLOCKS
There are mainly ten types of blocks available in Scratch 3.0. You will now learn about
some commonly used blocks. Blocks are the code or command used to create a program
in Scratch. These look like puzzle pieces and each block connects with other blocks to
perform a task.
Motion Block
The blocks that are used to control the movement of a Sprite are known as Motion blocks.
These are blue in colour. For example, the motion block move 10 steps is used to move a
sprite.
