ACTIVITY 3


               AIM       To observe the effect of heat on air.


               APPARATUS AND               Plastic bottle, balloon, a glass container
               MATERIALS                   filled with hot water, and a glass container
                                           filled with ice.
               STEPS


















            1.  Insert the nozzle of the balloon over  2. Immerse the plastic bottle into
               the mouth of the plastic bottle.             the glass container filled with hot
                                                            water and make an observation.

              What can you conclude about the size             conclusion based on
              of the balloon when the plastic bottle is        the results of Activity
              immersed in the glass container filled with:     1, 2 and 3?

              (a)  hot water?      (b)  ice?


                                                                                              HAWA
