How to use a thermometer A thermometer is an instrument that is the temperature. Depending on the country where you live, the temperature is measured in a plane called Fahrenheit or Celsius (sometimes called Centigrade). There are thermometers for food, people, and time.

Drop the straw into the bottle (which should touch the ground) and plug the opening with the clay. That's all. Now is the time to make sure your thermometer works.
