About Thermometers
- You must be very careful with thermometers because they are usually made of glass which can break and cut you.
- Most thermometers have a range of temperatures they can measure and some temperatures they can't. If you put a glass thermometer in a fire it will melt.
- A thermometer can show a negative temperature because the Celsius scale was chosen to have water freezing as 0 degrees Celsius. So anything colder than freezing water is given a negative temperature.
Examples
- A scientist measured the temperature of the snow.
- A Doctor measured the temperature of their patient.
- A scientist wants to measure the temperature of the air in the laboratory.
Used in a Sentence
- A thermometer was used to measure the temperature of the snow.
- The temperature of the doctor's patient was found using a thermometer.
- The scientist's thermometer showed the temperature in the laboratory was 20°C.
