"Temperature and Air Temperature" Weather PPT Courseware 2

Temperature has a great influence on the atmosphere and is an important data in the weather calendar. By observing and measuring the temperature of the atmosphere around us, we can know the local temperature.

Use of thermometer

Small activity: measure the temperature of the palm of your hand

1. Hold the thermometer in the palm of your hand for 1-2 minutes.

2. Take a reading when the liquid column of the thermometer is stable.

3. When reading, the line of sight should be parallel to the liquid column of the thermometer.

1. Fill in the blanks

1. Temperature has a great influence on the weather and is an important recorded data in the weather calendar. By observing and measuring the temperature of the atmosphere around us, we can know the local air temperature.

2. On a thermometer, zero degrees is used as the boundary. The greater the number of degrees above zero, the higher the temperature; the greater the number of degrees below zero, the lower the temperature.

3. Measure the temperature in the classroom. The thermometer is hung in an environment that is neither exposed to direct sunlight nor ventilated.

4. Measure the temperature in the early morning, morning, noon, afternoon, and evening of the day. The temperature is the highest at 2 p.m. and the lowest in the early morning.

5. From the time and temperature table, you can see the highest and lowest temperatures in a day and the changes in temperature.

2. Judgment

1. At the same moment, the indoor and outdoor temperatures are the same. ( )

2. Temperature changes vary from region to region. ( )

3. Temperatures tend not to change throughout the day. ( )

4. Different weather conditions will affect the temperature changes. ( )

5. When it rains, it is more accurate to measure the local temperature. ( )

3. Choice

1. The highest temperature of the day is in ( ) and the lowest temperature is in ( ).

A.morning B.morning C.afternoon D.evening

2. To read the thermometer, the line of sight should be ( ) the top of the liquid column in the thermometer.

A.higher B.lower C.eye level

3. When measuring the temperature, place the thermometer in the sun and compare the measured result with the actual temperature ( ).

A.Equal B.Higher C.Lower

4. We used a thermometer to measure the temperature at 14:00 that day was 35°C, so we know that it is ().

A.Spring B.Summer C.Autumn D.Winter

4. Short answer

Think about it, what factors are related to the temperature height? What are the patterns of temperature changes?

Answer: The temperature is related to factors such as the season, weather conditions, and different times of the day.

The changing pattern of temperature is: the temperature is higher in summer and lower in winter; the temperature is higher on sunny days and lower on rainy days; the temperature is higher at noon and lower in the morning and evening.
