                  We use the words ‘heavy’ and ‘light’ to compare the weights of objects. We can
                  compare the weights of some objects by just observing them.

                  Look at the following.

                    The pencil box is lighter  The crayon is lighter than  The car is heavier than a

                       than the school bag.                  a water bottle.                          cycle.

                           Think and Answer

                        1. Are smaller objects always lighter than the bigger objects?
                        2. take a banana in one hand and an orange in the other. Can you say which one is lighter?
                  A balance or Scale

                  When we are unable to say which item is heavier or lighter just by

                  viewing them, we use a balance or scale to compare weights. A
                  balance has two pans.
                  Look at the balance given here. There is a watermelon on one pan
                  and a papaya on the other. The pan with the watermelon goes
                  down. The pan with the papaya goes up.

                  Thus, the watermelon is heavier than the papaya or the papaya is lighter than the
                  watermelon.
