How would you use a thermometer to determine the temperature of a classroom?

To determine the temperature of a classroom using a thermometer, first ensure the thermometer is calibrated and functioning properly. Place the thermometer in a central location away from direct sunlight, drafts, or heat sources for an accurate reading. Allow it to stabilize for a few minutes, then read the temperature displayed. Record the measurement and, if necessary, repeat in different areas of the classroom for a comprehensive assessment.
