                    LEARNING OUTCOMES


                   The student will be able to:
                      use events blocks to trigger actions in Scratch.
                      utilise sound blocks to add and control audio in projects.
                      apply loops to repeat actions efficiently in Scratch.
                      create an interactive Scratch project using learned concepts.





                 In the previous chapter, you learnt that Scratch uses blocks that can be dragged and
                 combined to create a project. In this chapter, you will explore different categories
                 of Scratch blocks that help make your projects more engaging and interactive.

                 Let’s get started!




                           EVENTS BLOCKS


                 They are colour-coded light yellow and include blocks that detect events to trigger
                 scripts, such as when a sprite is clicked, a key is pressed, or the green flag is clicked.
                 These blocks are placed at the top of a script and determine when it starts running.




                         Blocks                                            Function



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

                                                  when  () key  pressed block  triggers  the  script  when

                                                  a specific  key  on the keyboard  is pressed. Useful for
                                                  interactive controls.
