Here, 10 is the number of steps that the sprite will move forward. You can change the
                  number of steps by clicking on the text box in the block and typing the new number.
                  To make the sprite move backward, give a minus (–) sign before the number as shown
                   move  -30 steps . This will move the sprite 30 steps back on the stage.


                       Looks Block

                  The blocks that are used to add speech and thought bubbles to the sprite are called Looks
                  Blocks. These are purple in colour.

                  For example, you want to add a speech bubble to the sprite for 2 seconds with a message

                  ‘Hello!’ as shown  say    Hello!  for 2  seconds .
                  You can change the message by clicking on the message text box and typing your own

                  message.

                  You can also change the time by clicking on the time text box.        think Hmm...  for 2  seconds

                       Events Block

                  This is the topmost block. It helps to run the script on the stage as it
                  controls the starting of scripts. It gives you the control of all the blocks        when     clicked
                  as without an event block no program will run.
                  To run a script, you have to click on the Go button before the other blocks.



                         ADDING A SPRITE


                  When you open Scratch, the default Sprite1 is the cat.
                  The location of the sprite cat is at the centre of the
                  stage. Let us add another sprite to the stage.

                  To add a sprite, follow the given steps:
                  Step 1:   Click on the Choose a Sprite tool in the Sprites                             1
