                     Computers help you work faster, but to make them do what you want, you need to
                     give clear instructions called codes. You’ve already learnt about Scratch Jr and

                     now it’s time to try Scratch 3. With Scratch 3, you can bring your ideas to life by
                     arranging colourful blocks to create exciting projects.

                             INTRODUCTION TO SCRATCH

                     Scratch is  a free and fun way  to  learn coding.  You

                     can make your own stories, games and cartoons by
                     snapping  colourful blocks  together.  It’s easy  to  use              Scratch was created by

                     ADVANTAGES OF SCRATCH

                     Scratch is the preferred language for young learners for the following reasons:

                          Commands are block-based, so there is nothing to remember.

                          Blocks can be dragged and snapped to build programs.
                          They fit together like puzzle pieces.

                          Each block has its own colour and group for easy finding.
                          Projects can be shared with others.

                                       Suppose, you have to code an environmental conservation game in Scratch
                                       where players work to protect endangered species and preserve ecosystems.
                                       What environmental challenges would they tackle and how would they make
                                       a positive impact?
