learning target

1. Understand that air temperature is the temperature of the air, a physical quantity that expresses the degree of hotness and coldness of the atmosphere.

2. Know that the shutter is an instrument used by weather stations to measure temperature.

3. Learn to draw temperature curves.

4. Understand the pattern of temperature changes throughout the day.

1. What is temperature and its measurement unit?

Air temperature is the temperature of the air, which is a physical quantity that expresses the degree of hotness and coldness of the air. The international standard unit of temperature measurement is degrees Celsius (℃).

In addition to the units mentioned above, the temperature units are expressed in degrees Celsius (℃), and some are expressed in degrees Fahrenheit (�).

In meteorological observations, the ground temperature refers to the air humidity measured at a height of 1.5 meters above the ground. Conventional surface temperature observation items include regular temperature, daily maximum temperature, and daily minimum temperature. Instruments used include thermometers, thermometers, etc.

The shutter is an instrument used by weather stations to measure temperature.

2. Observe the daily temperature table in Jixi City and draw a temperature curve chart

three. Guide to draw a temperature change curve.

(1) Draw two mutually perpendicular lines (horizontal and vertical)

(2) Write the time (hours) and temperature (℃) on the horizontal and vertical lines respectively.

(4) Mark the current temperature on the corresponding label. (mark small dots at the corresponding positions)

(5) Connect the small dots on each thermometer with wires.

Temperature changes throughout the day

Maximum temperature is the highest value of temperature in a day

The minimum temperature is the lowest value of the temperature in a day

During the day, the highest temperature occurs at 14:00 (2:00 pm), and the lowest temperature occurs at 6:00 am (around sunrise).
