Stage Area: It is similar to a stage in a play where everything takes place. You can
                      watch stories, play games and run your scratch projects on the stage. In Scratch,
                      the background is called backdrop.
                      Sprite: It is the actor who acts on the stage. Sprite is an object in Scratch that
                      performs the function on stage area. The default sprite in Scratch is an orange
                      cat.

                      Go Button: It is the green flag and when you click on it, it runs a Scratch program.
                      Stop Button: It is the red button which on clicking stops the running Scratch
                      program.

                      Sprites Info Pane: It is just below the Stage area. It shows all the details of sprites
                      and backdrops used in a project. You can add, delete, see the name and location,
                      increase and decrease the size of a sprite. Similarly, you can add or change the
                      backdrop.

                       Block Menu: It displays the categories of blocks based on their function and use.
                      These blocks within the same category share the same colour which allow better
                      distinction of the parts of a program.

                       Coding Area: It is also called the scripts area where you stack your blocks to
                      create scripts. If you save a project with a script, the script will also be saved.
                      When we click on a script, all the blocks execute from top to bottom.

                       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 a 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.
