"Temperature and Air Temperature" Weather PPT

Part 1: 1. Measurement and comparison of indoor and outdoor temperatures

What can be used to measure temperature?

thermometer

Remember the knowledge about thermometers? Tell which parts of the thermometer the arrows point to?

What should you pay attention to when using a thermometer?

1. Know the scale on the thermometer.

2. When measuring, keep the thermometer in the measurement environment for 2-3 minutes.

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

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

Is the temperature inside the classroom the same as outside the classroom today? Which one will be higher?

Temperature and air temperature PPT, part 2 content: 2. Measurement of air temperature

1. Measurement of temperature at different locations at the same time

(1) Measure the temperature at two different locations in the sun and in the shade at the same time.

Where can it better reflect the local temperature?

The temperature outside, in a cool, ventilated place can better reflect the local temperature.

What conclusions can be drawn from measuring the temperature at the same place at different times?

2. Measurement of temperature at the same place at different times

First, fill in the "One Day Temperature Measurement Record Form" with the temperatures collected by each group in the early morning, morning, noon, afternoon and evening of the previous day.

1. When is the temperature the highest in a day? When is the temperature lowest?

The temperature is highest in the afternoon (2 p.m.)

The temperature is lowest in the early morning (around sunrise)

2. Does the temperature change regularly throughout the day?

During the day, the temperature is the lowest in the early morning and evening, and the highest in the afternoon. The temperature is changing. The temperature pattern throughout the day is from low to high to low again.

Temperature and air temperature PPT, part 3: classroom exercises

1. Judgment questions

1. "℃" is the symbol for recording temperature. ( )

2. When observing the temperature, our sight must be level with the liquid level of the thermometer. ( )

3. Measure the temperature under a big tree. ( )

4. The hottest time of the day must be noon. ( )

2. Multiple choice questions

1.The highest temperature in a day is ( )

A 2 o'clock in the afternoon B Noon C Evening

2. 26℃ is read as ( )

A. Twenty-six degrees Celsius B. Twenty-six degrees C. Twenty-six degrees Celsius

3. Among the following three temperatures, ( ) is closer to the temperature reported in the weather forecast.

A Classroom 27℃ B Under the shade of trees 31℃ C Computer room 23℃

3. Picture-filling questions

Tell which parts of the thermometer the arrows point to?

4. Short answer questions

1. What are the specific steps to measure indoor and outdoor temperatures?

(1) Divide into several groups to conduct experiments, with 5 to 6 people in each group. Do a good division of labor within the group. Each group has a thermometer and an "indoor and outdoor temperature record sheet."

(2) Place the thermometer on the table for 2 minutes, read the temperature on the thermometer, and record it on the "Indoor and Outdoor Temperature Recording Table".

(3) Each group chooses a different outdoor location to measure the temperature. They are required to place the thermometer in a cool and ventilated place 1.5 meters above the ground for 2 minutes. They are not allowed to be exposed to the sun or rain.

(4) Record the measurement location and measured temperature on the "Indoor and Outdoor Temperature Record Form".

2. Is the temperature inside the classroom the same as the temperature outside the classroom? Which temperature reflects the local temperature?

no the same.

The temperature outside, in a cool, ventilated place can better reflect the local temperature.
