Human: How do I determine the melting point of sugar using a thermometer? Assistant: 
To determine the melting point of sugar using a thermometer, start by bringing a cup of sugar to a boil in a saucepan. Then, carefully remove it from heat and stir until all the sugar has dissolved. Once the sugar is completely dissolved, place the thermometer into the mixture and let cool for about 10 minutes. The temperature at which the sugar reaches its boiling point is the melting point.
