Relational Operators

                 Scratch has three operators that allow you to compare the relationship between two values or
                 variables. It will compare two numbers and decide whether it is true or false.

                 The three relational operators are:




                                                               greater than






                 Similarly, you  can  use the  other blocks  to perform less than                       and  equals  to

                              .

                 Logical Operators

                 Using logical operators, you can combine two or more relational operators to produce a single
                 true/false result. These blocks allow you to further refine your comparison of values.


                                                   The result is true only if the two expressions are true

                                                   The result is true if either of the expressions is true

                                                   The result is true only if the expression is false

                           #Logical operators


                   Write the answer as True or False. Consider the AND and OR as logical operators:
                   1.  (I am a girl) AND (I am 9 years old)

                   2.  (I am a girl) OR (I am 9 years old)
                   3.  (I am a boy) AND (I am 9 years old)

                   4.  (I am a boy) OR (I am 9 years old)

                   5.  (I am in Grade V) AND (I live in India)

                                                                                                              #Activity




                      SENSING BLOCKS

                 Sensing blocks in Scratch sense the input from the keyboard or the mouse at the time of

                 execution of a script. They are cyan in color. Some of the sensing blocks and their functions
                 are given below:
