             Aim: To state the meaning of force by carrying out an activity

             Apparatus and materials: pencil case, spring, ping-pong ball,
             bar magnet, paper clips

             Steps: Carry out the activities below and record your observations.



             1.                                          2.










               Push the pencil case.                       Pull the pencil case.

             3.                                          4.

             Questions:
             1.  What is the meaning of force?
             2.  What is the force applied in each activity above?
             3.  Which activity involves a force applied without the need for contact
                with the object? What is that force?


                                 What type of force is Earth’s gravity? Explain.
