Let’s learn how to make a simple weighing balance and weigh things using
                    non-standard weights.

                     •  Take two plas  c or thermocol plates. Make three holes near their edges at

                          equal distance.

                     •  Take 6 strong strands of wool or thread of equal
                          length.

                     •  Tie one strand of wool or thread on each hole
                          made in the plates as shown.


                     •  Take one plate and   e all the three strands of wool or thread together on
                          a hanger as shown.

                     •  Tie the second plate on the other end of the hanger.

                     •  Secure the thread on both sides

                          of the hanger using a tape a  er
                          balancing both the plates as
                          shown.

                          Your weighing balance is ready.

                          You can use stones, pebbles,
                          coins, marbles, etc., as non-

                          standard weights to weigh other
                          things.

                    Now using the weighing balance made by you, weigh the objects listed in the

                    table.
