    BLOCKS IN SCRATCH

                     Blocks in Scratch are like jigsaw puzzle pieces. They connect vertically to create code. Each
                     block has a unique shape and slot. Simply drag them into the coding area to build a script.

                     Motion Blocks

                     Motion blocks let you control a sprite's movement on the stage, allowing it to move, turn and

                     change direction. They are blue in colour.

                     Some basic motion blocks used in Scratch and their descriptions are as follows:

                                                            This block makes the sprite move forward and backward,
                                                            allowing it to travel in both directions.

                                         move  10  steps    For example: Move 10 steps moves the sprite forward by
                                                            10 steps or Move -10 steps moves the sprite backward by
                                                            10 steps.

                                                            This block makes the sprite turn to the right (clockwise),
                                     turn    15  degrees
                                                            rotating in a circle.

                                                            This block makes the sprite turn to the left
                                     turn    15  degrees
                                                            (anticlockwise), rotating in the opposite direction.

                     Events Blocks

                     Events blocks run the script on the stage and control the start of scripts. Without an Events
                     block, no program will run. They are light yellow in colour.

                     Some of the commonly used Event Blocks with their description are as follows:

                                                            This block starts the script when the green flag is clicked.
                                          when    clicked
                                                            It is used to begin a project.

                                                            This block  starts the  script when  a chosen  key  on  the
                               when   space   key pressed
                                                            keyboard is pressed.

                                                            This block runs the script when the sprite is clicked.
                                      when this sprite clicked

                     Looks Blocks

                     Looks blocks changes how a sprite looks or what it says on the stage. They are purple in colour.

                                                                                                   Let’s Learn Scratch  65
