    Aryan: Ok dear! Thanks, for explaining this block. Now please tell me what is this
                                       “stop all” block?
                                       Gowri: Yes, sure dear, this block is a “cap” block and has a drop down also.

                         Aryan:  What is this “cap”  block?  I have  heard about “stack”  block,  “hat”  block,  “c-block”,
                         “boolean” block but what is this “cap” block now?

                         Gowri: Yes dear, “cap” block is the block which ends the script here, means no more
                         block can be added after that block. We can also say it as the reverse of “hat” block.
                         “Hat” block is the start of the script and “cap” block is the end of the script.

                      3.7  STOP BLOCK— “CONTROL” BLOCK

                      This is a “cap” block.

                         Gowri: Let’s understand this now that this block has three options in dropdown which are:-

                      3.7.1. “stop all” block
                      This means, it will stop “all” the scripts running in Scratch project, either on this
                      sprite or any other sprite.

                      3.7.2. “stop this script” block
                      This means; it will stop all the running scripts of this “sprite” only in Scratch project.

                      3.7.3. “stop other scripts in sprite” block

                      This means; it will stop all the running scripts of this sprite, written under any “hat” block.

                                       Aryan: OK! Thanks, dear Gowri, today I have learnt so many interesting blocks of
                                       Scratch. With these blocks, I could make so many games etc. But I wish, sprites
                                       can create so many copies of themselves and also destroy them automatically.

                                      Gowri: Yes dear, it’s definitely possible that copies of the sprite
                                      can be created automatically, as and  when required  and  can also
                                      destroy itself when required. But we will learn these blocks in the
                                      next class.

                         Aryan: Ok Dear Gowri, I am very much excited to learn these blocks also. Thanks, dear, for
                         these blocks that you have taught me in this class.

                      Let us revise what we have learnt:
                            There are a total of 9 blocks in the sound blocks.
                      Ø
                            Control block is used to repeat the blocks of instructions for some specific
                      Ø
                            number of times.

                            Sensing block also known as Boolean block.
                      Ø
                            If condition? Then block is used for asking the questions and returning the
                      Ø
                            answer in true or false.
