Take some ice cubes and dry them using a filter paper and quickly put them in a beaker.
Place the beaker over a wire gauze kept over a tripod stand.
Suspend a thermometer (temperature range -10 to 110°C) with the help of a clamp stand so that its bulb remains in the middle of the ice cubes.
Ice cubes are moderately heated by a gas burner and stirred continuously using a glass rod.
Note the temperature (t1) when the ice starts melting.
Continue heating the ice.

When a satisfactory melting point range has been determined, choose a known substance that has a melting point within 5degreec of the observed value.
Melting point of water is 100degreec.
Melting point of water is 100degreec.
