    Sprites Info Pane: 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 Palette: It displays the categories of blocks based on their functions and uses.

                       Script: Script is a collection of a number of stacked blocks. Script is actually a program which
                     gives the instructions in the form of blocks. A script must have at least two blocks.
                       Coding Area: It is the area where you stack your blocks to create scripts. When we click on
                     a script, all the blocks execute from top to bottom.
                       Tabs: Scratch has mainly three tabs which are described below:

                         Code Tab: It contains block categories and the list of blocks in a category. The categories
                       are—Motion, Looks, Sound, Pen, Events, Control, Sensing, Operators, Variables, and
                       My Blocks. All block categories are of different colours. 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

                  Blocks are the codes or commands used to create a program in Scratch. It looks like a puzzle
                  piece and each block connects with the other block to perform a task.

                  Motion Block

                  The blocks that are used to control the movement of a sprite are known as Motion blocks.
                  They are blue in colour. For example, the motion block is used to move a sprite.

                  Here, 10 is the number of steps that the sprite will move forward  move 10       steps . You can change
                  the number of steps. To make the sprite move backward, give a minus (–) sign before the

                  number as shown       move -30  steps  . This will move the sprite 30 steps back on the stage.

                  Looks Block

                  The blocks that are used to add speech and thought bubbles to the sprite are called Looks

                  Block. They are purple in colour.
                  For example, you want to add a speech bubble to the sprite for 2 seconds with a message

                  ‘Hello!’ as shown  say Hello!  for 2  seconds .

                  You can change the  message by  clicking  on the  message text box  and  typing  your own
                  message. You can also change the time by clicking on the time text box.  think Hmm...       for 2  seconds
