    PROJECT

                                                              SCRATCH

                                          Gowri: As we have learned so many blocks and features of Scratch in class 3.
                                          Let’s make a project now using “pen” extension.

                                          Aryan: Yes, I have learnt so many blocks in class 3 and I
                                          liked the Scratch software very much. But what is this
                                          “Pen” extension? I haven’t learnt this till now.

                            Gowri: Yes, dear Aryan. In this project we will learn this also. We will
                          make a project using this “pen” extension and other blocks of scratch
                          learnt so far.

                          Aryan: Ok dear Gowri, please tell me, what is this “Pen” extension? Also
                          tell me how to use this extension.
                            Gowri: Sure! Sure! Let’s understand this now: -
