Description

"Temperature" Changes in State of Matter PPT Courseware 7

Knowledge and skills:

1. Understand the working principle of a thermometer.

2. Understand and remember some common temperature values ​​in living environments.

3. Can use a thermometer to measure the temperature value.

Process and methods:

1. Understand the structure and working principle of a thermometer through observation and experiments.

2. Master the use of thermometers through learning activities.

Emotional attitudes and values:

1. Through the study of this lesson, learn to connect physics with life and fall in love with physics.

Highlights:

1. Understand the unit of temperature in Celsius.

2. Will use the thermometer correctly.

difficulty:

1. Understand the unit of temperature in Celsius.

2. Will use the thermometer correctly.

Do it: The temperature you feel is unreliable. To accurately judge and measure temperature, you must choose a scientific measurement tool - a thermometer.

1. Group discussion and exchange

1. Observe and explain the phenomenon when a simple thermometer measures temperature, and summarize the design principles of the thermometer.

2. How to improve the measurement results to make them more accurate?

2. Independent learning: reading P47-P48

1. What is the expression of temperature in Celsius?

2. What is the regulation of 0 degrees Celsius?

3. Regulation of 100 degrees Celsius?

4. What is the 1 degree Celsius rule?

5. How to read and write temperature?

1. Temperature represents the degree of hotness and coldness of an object. It can only be distinguished as "high or low", not "with or without".

2. Whether there is a lot of ice or a lot of water, as long as it is a mixture of ice and water, its temperature is 0 degrees Celsius.

3. The unit of Celsius temperature is "Celsius" which is a whole and cannot be separated. For example, 30oC is read as 30 degrees Celsius, but 30 degrees Celsius cannot be read.

4. For temperatures lower than 0oC, add "-" before the number and read it as "negative" or "below zero".

3. Group discussion, small teacher explanation

How to use a thermometer correctly: (P49-P50)

1. What should you pay attention to before using a thermometer?

2. What is the graduation value and range of a thermometer?

3. Tell us what are the ranges and graduation values ​​of the thermometer and thermometer used in the experiment?

4. How to use a laboratory thermometer correctly?

5. Teacher summary, student notes

A. See clearly the range and graduation value of the thermometer;

B. The glass bulb of the thermometer should be completely immersed in the liquid and should not touch the bottom or wall of the container;

C. Wait for a while after the thermometer is immersed in the object to be measured, and then take a reading after the thermometer's reading is stable;

D. When reading, the glass bulb of the thermometer should remain in the liquid, and the line of sight should be level with the liquid surface in the thermometer.

6. Summary of this lesson

1. Temperature:

2. Working principle of thermometer:

3. Regulations for 0 ℃ and 100 ℃:

4. Correct use of thermometer:

(1) The glass bulb of the thermometer is completely immersed in the object being measured, but cannot touch the bottom or wall of the container;

(2) Wait for a while after the glass bulb of the thermometer is immersed in the object to be measured, and then take a reading after the reading is stable;

(3) When reading, the glass bulb of the thermometer cannot leave the object being measured (except the thermometer), and the line of sight must be level with the upper surface of the liquid column in the thermometer.

7. In-class testing and high school entrance examination links

1. The normal human body temperature is approximately ______, pronounced ______.

2. The measuring range of the thermometer is ______, and the graduation value is _____

3． (2008 Shandong) Use the same thermometer to measure the temperature of water at 0°C and ice-water mixture at 0°C. The following statement is correct: [ ]

A. 0℃ water temperature is high

B. The temperature of the ice-water mixture at 0°C is high

C. Both have the same temperature

D． Can't compare
