3 teaching plans for geography teaching in senior high school in 22

Modern people sum up several elements of success: correct thinking, unremitting action, great personality, skillful skills, godsend opportunities and precious health. It can be seen that if you want to succeed, you must not only eat bitterness in bitterness, but also cooperate with the support of relevant conditions. Those who only know hardship, those who eat bitterness that is not worth eating, and those who regard hardship as a magic weapon to solve all problems, I am afraid that they can only continue to wander in the strange circle of "bitterness in bitterness". Next is the 22 senior high school geography teaching plan I compiled for you, I hope you like it!

Not only the Maldives, but also the positions all over the world can't be maintained.

Global climate change has deeply and widely affected human beings. Next, we will go into Kenya in Africa to see what impacts climate change has brought.

Next, we are going to a beautiful and mysterious place. Please take pens and watch videos while recording the impact of climate change. Concentrate, listen carefully and take notes quickly. Let's compare which group remembers the most!

"Who brought it? The ancient call ...

The wonderful singing brought us to the roof of the world of the earth-the magical Qinghai-Tibet Plateau.

the Qinghai-Tibet plateau, which was originally "too high to be cold", experienced climate change and became one of the most typical affected areas of global climate change.

monitoring and research show that the annual average surface temperature in Tibet has increased by .31℃ every 1 years in the past half century, and the frequency of extreme high temperature has increased significantly, while the annual precipitation has increased by 33mm, and the plateau glacier area has shrunk by 15% in the 3th grade.

As the temperature rises, the precipitation increases, which is beneficial to forage growth, forage yield and livestock survival rate. It has also changed the planting system in agricultural areas, expanded the suitable planting area of crops, and expanded the space for structural adjustment of agriculture and animal husbandry.

With the increase of precipitation, the area of glaciers, lakes and marshes on the plateau are increasing, and the visual effect of plateau landscape is better.

While the ecological environment of the plateau has been improved as a whole, snowmelt runoff has sometimes caused floods, landslides and mudslides. Affect production and herdsmen's life. Climate warming also leads to the melting of frozen soil, and the diseases of frozen soil on plateau highways are aggravated. Many drivers who run transportation report that some road surface undulations are becoming more and more obvious.

The influence of climate change is summarized. Do students understand the process of climate change affecting human activities? Please complete the third question and fill in the appropriate blanks with the principle of wholeness.

From these two diagrams, we can summarize the process of global climate change affecting human activities.

According to the research, human activities have aggravated global climate change

Pressure belt and wind

Teaching objectives

(1) Combining the two parts of "thermal circulation" and "horizontal movement of the atmosphere-wind", under the guidance of teachers, we can know the formation process of pressure belt and wind belt.

(2) On the basis of knowing the formation process of pressure belt and wind belt, master the distribution of pressure belt and wind belt, and draw the global distribution diagram of pressure belt and wind belt.

(3) Understand the influence of pressure zone and wind zone on precipitation.

(4) master and tell the movement law of pressure belt and wind belt.

Teaching focuses on difficulties

1. Teaching focuses

Distribution of air pressure belts and wind belts; Seasonal movement law of pressure zone and wind zone.

2. Difficulties in teaching

The causes of the formation of air pressure belts and wind belts and the drawing of their distribution diagrams; Influence of pressure zone and wind zone on precipitation.

Teaching process

1. Introduce the poem titled "The South Village of the Capital" written by Cui Hu, a poet in the Tang Dynasty: Last year, in this door, peach blossoms set each other off, and people don't know where to go, but peach blossoms still smile in the spring breeze. Lead out the theme of this lesson "Wind".

2. the concept of wind. Wind is the horizontal movement of the atmosphere from high pressure area to low pressure area under the action of horizontal pressure gradient force.

Review the knowledge of thermal circulation, and illustrate with examples what is the horizontal pressure gradient force.

3. the direction of the wind. It can be summarized in three situations.

(1) The wind direction is perpendicular to the isobar when it is only affected by the horizontal pressure gradient force (ideal case);

(2) The wind direction is perpendicular to the geostrophic force (high altitude) when subjected to the pressure gradient force and geostrophic force;

(3) When the pressure gradient force, geostrophic deflection force and friction force act at the same time, the wind direction forms a certain angle with the isobar (near the ground).

summary. Think about it: What other poems or idioms are related to wind in life? Play the theme song of Valley of the Wind.

Transition: (1) Give the material "Japan's Wind War to the United States during World War II" and think about how the hydrogen balloon bomb crossed the ocean from Japan to the United States. (2) Explain the short story-the problem of "horse latitude" and the appearance of the roaring westerly belt, so that students can think about the reasons. Lead to the topic-the formation of pressure zone and wind zone.

5. Atmospheric circulation: global regular atmospheric movement.

6. Three hypotheses are used to analyze the formation process of wind zone in pressure zone.

(1) hypothesis 1: the surface is uniform, regardless of the earth's rotation (geostrophic deflection) and revolution

The factor that causes atmospheric motion is uneven heating between high and low latitudes.

Forming a single-circle circulation

(2) Hypothesis 2: The surface is uniform, considering rotation and not considering revolution

The factors that cause atmospheric motion are uneven heating between high and low latitudes+geostrophic deviatoric force

Forming a three-circle circulation

Video playback: "News-global high temperature is caused by subtropical high pressure belt"

Focus on the formation of three-circle circulation.

Thinking: What are the differences between the equatorial low pressure belt and the sub-polar low pressure belt? What is the difference between the causes of the polar high pressure zone and the subtropical high pressure zone?

The former is formed by air movement caused by uneven cold and heat, so it is formed by thermal reasons. The latter is formed by the change of air quality caused by atmospheric movement, so these two pressure belts are formed by dynamic reasons.

(3) hypothesis 3: the surface is uniform, and the rotation and revolution of the earth are considered.

the direct point of the sun moves north and south with the seasons-the pressure belt and wind belt also move periodically in a year.

the seasonal movement law of the pressure belt and wind belt: in the northern hemisphere, compared with the equinox, the positions of the pressure belt and wind belt are generally north in summer and south in winter.
