A program is a set of instructions written in a specific programming language to do a
                      specific task.
                       Scratch  is an easy-to-learn  visual programming  language  developed  by the Lifelong
                      Kindergarten Group at the MIT Media Lab.
                       A sprite is a key element that serves as the main character or object in a project.

                       Blocks are just like pieces of the jigsaw puzzle available in different shapes.
                       Motion blocks in Scratch are used to control the movement of the sprite.
                       Looks blocks in Scratch are used to control the appearance of the sprite.
                       Sound blocks in Scratch are used to control the sounds and music.

                       Events blocks in Scratch are used to detect events and trigger scripts when those events
                      occur.
                       Control blocks are used to manage the flow and logic of the program.
                       Sensing blocks in Scratch are used to detect various conditions and interactions within
                      the project, such as touch, mouse position, and distance.
                       Operators  blocks in Scratch  are  used for  performing  mathematical operations,
                      comparisons, and handling strings.

                       Variables blocks in Scratch are used to store and manipulate data values.
                       Pen blocks allow you to stamp the sprite, draw lines on the stage, change the colour and
                      thickness of lines.
