Teaching design of "How high is the temperature" in primary school science

How high is the temperature in teaching design?

How high is the temperature?

First, the teaching purpose:

Process and method

1, can see correctly, read and write temperature.

2. The temperature in different environments can be accurately measured and recorded.

3, you can use the statistical chart of temperature change records to find out the law of temperature change in a day.

Knowledge and skills

1, know the correct method of reading, writing and reading temperature.

2. Know that a thermometer can also be called a thermometer.

3. Different ambient temperatures are different.

4. The general rule of 4.YCB gear pump is that the temperature changes in the daytime are low in the morning and evening and high in the afternoon.

5. Know the significance of standardized measurement.

Emotions, attitudes and values

1, aware of the importance of evidence, holding a scientific attitude of attaching importance to evidence.

2, have a standardized sense of scientific observation, can realistically reflect the measurement results.

Second, the teaching focus:

Know the correct method of reading, writing and reading temperature.

Third, teaching difficulties;

1, know that a thermometer can also be called a thermometer.

2. Different ambient temperatures are different.

3. Know that the general law of temperature change during the day is that the temperature is low in the morning and evening and high in the afternoon.

Fourth, teaching preparation:

1. The models are cold KCB stainless steel gear pump thermometer and student thermometer.

2. Thermometer, pen and paper for recording temperature.

Verb (abbreviation of verb) class division:

One class hour

Seven, teaching steps

The interaction of teaching steps and the purpose of teacher-student interaction

Focus on the topic 1. The teacher asked which classmate watched the weather forecast last night, and who would be the weather forecaster and make the weather forecast. (report by name)

Do you know how we measure temperature? With what tools? The teacher shows the thermometer and thermometer according to the students' answers. )

What were you thinking when you saw the thermometer? What liquid is in it? How to read? Why is it called centigrade? Say its name. ) The teacher introduces the thermometer.

4. Talk to each other on the same seat about how to read the thermometer.

Point to any scale and talk to each other.

5. What other temperature measuring instruments have you seen? Can you introduce it? Introduce a new lesson to guide students to read and write about temperature.

Explore and

Investigation 1. The teacher explained the requirements for the use of thermometers.

(1) Measure with a thermometer and gently hold both sides with your hands.

(2) Look up at the top of the red alcohol column and read the scale.

Question: Why do you look up? What will happen if you look up? What will happen if you look down? The result of looking up is too big, and the result of looking down is too small. Look up. ) can be demonstrated with the help of charts.

2. Teachers organize group discussions

What should I pay attention to when measuring temperature? (For example, measure at the same time, in a sparsely populated and ventilated place, until the liquid level is completely static and read ...)

3. Teachers arrange survey requirements

(1) Measure the temperature in the classroom, in the sun, in the shade, on the ground, on the grass, on the concrete floor and at a distance of 1.5m from the ground. Two people in the same seat, a classmate, measure, and a classmate record.

(2) After the measurement, fill in the first question of "Activity Record" on page 83 of the textbook.

4. Start measuring, 15 minutes. Teachers' patrol guidance.

5. The teacher organizes class communication.

What do you find by comparing the measurement results?

(For example, the temperature in the shade is lower than that in the sun, and the temperature in the classroom is lower than that in the sun ...)

Why did you find the conclusion?

6. The "communication" on page 4 1 in the textbook is discussed collectively by the whole class. (This part should be tested one day in advance for each group, and can be tested after each class. ) What do you find from the temperature change in a day? (For example, the temperature is the highest at noon 13: 00 to 14: 00, and the temperature is basically the same at 6: 00 in the morning and 18: 00 in the evening ...)

1, instruct students to measure temperature.

2. Students can learn about the law of temperature changes during the day through communication.

Review and

Explain 1, insist on measuring the temperature for one week and make records. Consolidate what you have learned.

Summarizing how high the temperature is, the teaching plan is introduced here for everyone, hoping to help everyone learn. More learning content, all in the boutique learning network, please pay attention in time.
