? Students have learned the correct reading and writing methods of thermometers through the study in the last class. In this lesson, we will use a thermometer to measure the temperature and find out the law of temperature change in a day.

In the key part, the focus of this lesson is to measure the temperature.

In the exploration part, correctly grasp the use method of thermometer and the matters needing attention in the use process; During the epidemic, indoor measurements were conducted in pairs.

This paper analyzes the causes of this phenomenon by measuring the temperature in the classroom at the same time and in different places.

Expand the video playback section to learn how the weather station staff measure the temperature.
