Script is actually a program which gives 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 as follows:
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 Sprites and backdrops.
