Teaching plan of lightning protection safety education theme class meeting

Teaching plan of lightning protection safety education theme class meeting

As a selfless people's teacher, asking him to write lesson plans at ordinary times is conducive to improving the teaching level and carrying out teaching and research activities. So what problems should we pay attention to when writing lesson plans? The following are the class meeting teaching plans with the theme of lightning safety education that I collected and sorted out. Welcome everyone to learn from and refer to. I hope it helps you.

Theme class meeting of lightning protection safety education 1 teaching plan guiding ideology;

At the class meeting, students were given safety knowledge propaganda on "prevention of drowning and lightning protection" in various forms, including "common sense of drowning" and "prevention and first aid of drowning", so as to help students understand the harm of lightning and how to prevent it, create a harmonious and safe learning atmosphere for students, avoid the harm caused by natural disasters, and enable students to further master relevant life-saving and self-help knowledge and further improve their safety awareness and self-protection ability.

Activity purpose:

1 Have a preliminary understanding of drowning safety, and know that every student should improve safety awareness.

2. Use lightning protection knowledge publicity activities to continuously improve students' self-safety awareness.

Pay attention to the study of lightning protection and drowning prevention safety knowledge, enhance students' self-protection awareness and improve their self-protection ability.

Activity form:

Priority discussion

Class meeting process:

Monitor: We are the future of our motherland and the hope of our nation. We love studying and working, and we are a new generation full of energy. We grew up in the warm sunshine of the party and matured day by day under the careful cultivation of teachers. We are new seedlings that shoulder heavy responsibilities and cross the century. However, we often hear about some drowning accidents and see some shocking and terrible disasters happening around us. Then how can we care for life and prevent drowning?

The theme class meeting of Class Two (2) on caring for life, preventing drowning and lightning protection begins now.

A: Summer is coming, and summer vacation is coming. Swimming is everyone's favorite summer activity.

B: Yes! For students, swimming can not only exercise and enhance physical fitness, but also improve the coordination of the body. But swimming must pay attention to certain safety. Many teenagers drown in swimming every year. Examples and groups of data are really shocking.

First, listen.

Monitor: How much do the students know about the teenage swimming drowning accident that happened around us last year? Who wants to talk?

On April 5th, 65438, students from shitai county Middle School 1 Senior One swam in the river with their classmates without authorization and drowned in muddy water. On May 7th, seven primary and middle school students from Yingxian County, Shanxi Province went to play in a reservoir. Among them, 1 5 grade girls accidentally stepped on the air and fell into the water while washing their hands by the reservoir. Other companions reached out to save the students who fell into the water, and five students successively fell into the water and drowned. On May 15, four students from Shitang High School in quanzhou county, Guangxi Zhuang Autonomous Region went out to play and were flooded on their way back.

Second, discuss it.

Monitor: Students, why do these children have drowning accidents? What safety rules did they violate?

A: Some students go into the water without being accompanied by an adult. Some students try to be brave and win, diving into the water without knowing the depth of the water; Some even swim in the water for more than two hours and do various postures, so it is easy to drown because of physical exhaustion; Wait a minute.

Yes, there are various reasons for the accident. But many can be avoided. So how to avoid child drowning accidents as much as possible?

A: We must start from many aspects. For example, parents should strengthen personal safety monitoring measures for summer children and remind them not to swim in reservoirs, ponds and other waters without authorization. Swimming must be accompanied by life-saving facilities and adults familiar with water, and swimming in the swimming pool must be accompanied by professional life-saving personnel. Children must master the necessary knowledge of swimming safety. You must also master the necessary swimming first aid knowledge and self-help knowledge. Wait a minute.

Third, talk about it.

Monitor: Now let's talk about swimming safety knowledge.

A: Keep yourself in good health; Don't be too hungry and full when you go into the water. Don't go into the water for an hour after meals to avoid cramps; Drinking is not suitable for swimming; Open wounds, skin diseases and eye diseases are not suitable for swimming; If you have a cold, are sick, are unwell or weak, you are not suitable for swimming.

B: make full preparations to prevent cramps; Warm up your body. Before swimming, grab some water on your limbs and then jump into the water. Don't jump into the water at once; When you have abdominal pain, you should go ashore. You'd better drink some hot drinks or soup to keep warm.

C: create a safe swimming environment and be careful of drowning; Don't go with the flow, especially in the wild; Try the water temperature before entering the water. If the water is too cold, don't go into the water. Don't swim when the wind and waves are too strong and the lighting is not good; If you swim in rivers, lakes and seas, you must have a companion. You can't swim alone. Observe the swimming environment before launching. You can't swim here if there is a danger warning.

D: It is forbidden to make excessive jokes with your companions when swimming; You should swim where there are lifeguards and where conditions permit.

Monitor: How to save yourself in case of drowning?

A: In case of unfortunate drowning, students should not panic, stay calm and actively save themselves: don't panic and rummage in the water, please stay calm in case of cramps; When drowning happens, you can take the method of self-help if you are not familiar with water. At this time, don't panic, don't raise your arms and flutter, so your body will sink faster.

B: For people who have cramps in their hands and feet, if they have cramps in their fingers, they can hold their hands tightly, then open them forcibly and do them several times quickly until the cramps are eliminated. If the calf or toe cramps, first take a deep breath and float on the water, hold the toe of the cramped limb with the hand opposite to the cramped limb and pull it toward the body. At the same time, press the palm of the same side on the knee of the cramped limb to help the cramped leg straighten. If the thigh cramps, it can also be solved by lengthening the cramped muscles.

A: Students, if you encounter a drowning person, you should swim to the vicinity of the drowning person quickly, observe the position clearly and rescue from the rear. Don't go into the water to save people when you are not sure. You can call for help while using bamboo poles, branches, ropes, clothes or floating objects to save people. Let the drowning man climb ashore.

Monitor: How to give first aid when rescuing drowning people?

Answer: After the wounded are carried out of the water, the water, mud and dirt in their mouth and nose should be removed immediately. Wrap the finger with gauze (handkerchief) and pull the tongue of the wounded out of the mouth, unbutton the button and neckline, and keep the respiratory tract unobstructed. Then, he picked up the wounded man's waist and abdomen, poured water on his back, and his head drooped.

B: People who stop breathing should be given artificial respiration immediately. Generally speaking, mouth-to-mouth blowing has the best effect.

C: People with cardiac arrest should have a chest massage first.

Four. abstract

A: At the class meeting today, we publicized the safety knowledge of "prevention of drowning" to the students in various forms, including "common sense of drowning" and "prevention and first aid of drowning". Educate students to maintain a high degree of safety awareness, raise awareness of the dangers of drowning and resolutely put an end to drowning accidents.

B: After today's study, we have mastered swimming safety knowledge and basic first aid knowledge. In order to better remember, I am here to recite the poem "Song of Drowning Prevention" to my classmates.

I have a wonderful plan to prevent drowning. The first plan is to be accompanied by an adult. Swimming without permission is dangerous, and it is important not to go to deep water.

I have a wonderful plan to prevent drowning. The second plan is to warm up before swimming. Reaching out, kicking, bending, and preparation are essential.

I have a wonderful plan to prevent drowning, and a third plan to relieve cramps. It is important to go ashore and have a cup of sugar water to relieve fatigue.

You should know the measures to prevent drowning and should not be conceited. Remember the word "safety". It's good to stay away from danger.

5. What is lightning? Frequency and characteristics of lightning (lightning)

Case Description: Time: May 2004 18 Night Location: Guiyang City, Guizhou Province

That night, the weather was sultry and gloomy. Fan Shicheng, the contractor of Maiping Township shale brick factory in Huaxi County, Guiyang City, and Zhou Xiaoping, and how seven people are sitting around the factory shed for dinner. 10 Around 8 o'clock, there was a sudden thunder, and Fan Shicheng, who was leaning against the door, fell to the ground. Seeing this scene, the migrant workers carried him to bed and called the hospital for help. Two hours later, the medical staff arrived and Fan Shicheng was dead. After the event, the on-site investigation data of relevant departments showed that the height of migrant workers' sheds was only 3 meters, there was no lightning protection device, and the outdoor antenna of TV set was 5 meters higher than the roof. The antenna installation point is 2m away from the disaster site. Fan Shicheng was standing by the door in wet clothes when the lightning accident happened, and the TV antenna connection was behind him.

Six, the harm of lightning

The harm of lightning to human body includes the direct action of current, overpressure or electric power and high temperature. When a person is struck by lightning, the current will pass through the human body quickly. In severe cases, it will lead to heartbeat, respiratory arrest and brain tissue hypoxia and death. In addition, when lightning strikes, sparks will be generated, which will also cause different degrees of skin burns. Lightning injury can also cause dendritic lightning stripes, epidermal peeling, intradermal bleeding, eardrum or visceral rupture.

7. Where is the lightning strike?

1. Tall buildings, storage tanks, etc. Lack of lightning protection devices or unqualified lightning protection devices;

2. The metal roof is not well grounded;

3. Buildings and trees in wet or open areas;

4. Due to the conductivity of flue gas, chimneys are particularly vulnerable to lightning strikes;

There is a radio in the building, but there is no lightning arrester and no good grounding.

Eight, how to lightning protection

1. Lightning protection device is installed on the building. That is, lightning protection devices are used to introduce lightning current into the earth and then disappear.

2. During a thunderstorm, people should not go near high-voltage distribution rooms, high-voltage wires and isolated tall buildings, chimneys, poles, trees, flagpoles, etc. Not to mention standing in an empty highland or under a big tree to shelter from the rain.

3. You can't use umbrellas with metal columns. Do not use metal tools, such as crowbars, when working in the suburbs or in the open air.

4. Don't wear wet clothes near or stand on metal objects in the open air.

5. Don't go swimming, boating and fishing in rivers and lakes in thunderstorm weather.

6. When it is thunderous and stormy, tourists should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid conduction. It's safer in the middle of the room when it thunders. Don't stay under the electric light, and don't lean against posts, walls, doors and windows, so as to avoid accidents caused by induced electricity when it thunders.

Students discuss how you think lightning protection should be done.

1, when it thunders, close the doors and windows, try not to make phone calls, answer phones, mobile phones or surf the Internet, and unplug the metal wires that may lead to lightning, such as the power supply of household appliances, telephone lines and TV closed wires.

2. Keep away from the metal water pipes and sewer pipes connected to the roof indoors, and do not pull the wires to the doors and windows.

3. In case of sudden thunderstorm and stiff standing, kneel with your feet together and take off metal objects, hairpins, necklaces, etc. Don't get involved with people. It is best to use plastic rain gear, raincoat, etc.

4. When going out to avoid a thunderstorm, be careful not to hide in dangerous places such as caves, rocks, cliffs, huts and solitary trees.

5. Pay attention to the weather forecast, try not to go out in thunderstorm weather, and take emergency precautions in advance.

Monitor: The class meeting of Class Two (2) entitled "Cherish Life, Prevent Drowning and Lightning Strike" ends here.

Class teacher's comments: Students, after today's study, we have mastered the knowledge of swimming safety and basic knowledge of first aid, further enhanced our awareness of self-protection, and provided a strong security guarantee for the upcoming summer students' high incidence of drowning. During the long vacation in hot summer, I hope everyone should always keep a sense of safety protection when going out to swim and choose a safe swimming place to swim. Teachers also hope that through this lightning protection class meeting, students will know the importance of lightning protection, apply what they have learned in their daily work, study and life, and be students who know how to protect themselves.

Theme 2 of lightning protection and safety education: The instructor leads the team members to sing the team song, and the class meeting to win the team flag is presided over by the following squadron leader xx:

Firstly, introduce the formation, power and harm of lightning to students. (Multimedia Import)

1, introduce the formation of lightning.

Lightning is a large-scale spark discharge phenomenon in the atmosphere, which is mainly produced in cumulonimbus clouds. During the formation of cumulonimbus clouds, some clouds are positively charged and some clouds are negatively charged. They make the earth's surface or buildings produce different charges. When the charge accumulates to a certain extent, the electric field intensity between different clouds or between clouds and the earth can break through the air (generally E = 25-30 kV/cm) and start to discharge, which is called "pilot discharge".

Cloud-to-ground pilot discharge is the gradual development of cloud jumping to the ground. When it reaches the ground (or buildings or overhead transmission lines on the ground), it will produce a reverse-guided main discharge from the ground to the cloud. In the main discharge stage, due to the strong neutralization of opposite charges, a large current will be generated. Due to the work done by the current, the instantaneous temperature of the gas through which the current passes can rise sharply to about 30 000 degrees Celsius, thus showing a strong flame. This is us.

2. The power of lightning.

The average lightning current is about 20,000 A (even larger), the lightning voltage is about 10 power volt (36 volts for human safe voltage), the lightning time is about one thousandth of a second, and the average power emitted by lightning is 20 billion kilowatts (the power of ordinary rice cookers is lower than 1000 watts).

The Three Gorges Hydropower Station, the world's largest hydropower station built in China, has a total installed capacity of 654.38+08.2 million kilowatts, which is only one thousandth of the lightning power. Of course, although the electric power of lightning is very large, the electric power of lightning current is not large because of the short discharge time, which is about 5555 degrees at a time. There are more than 100 times of lightning every second in the world, and the total electric energy released by lightning in one year is about175 billion kWh. If the one-time electricity bill is 0.30 yuan, then the annual lightning value in the world is 5.25 trillion yuan, which is a huge wealth. However, due to the short time of lightning, human beings can't capture this kind of electricity, and there is no way to use lightning electricity in the world at present.

3, the harm of lightning (students can be arranged to speak after the exchange).

Strong thunderstorm is a kind of disastrous weather, and radar will cause lightning fire. Because lightning is mainly produced in cumulonimbus clouds, which are the products of strong convection in the air, lightning and thunder are often accompanied by severe weather such as strong winds, showers or hail. Strong winds blow down houses, uproot trees (sometimes split by lightning), crops are hit by hail, and heavy rains cause geological disasters such as flash floods and mudslides. The casualties and property losses caused by lightning are shocking. Lightning has brought great disasters to human society with its great destructive power, and the threat to national economy and life safety is becoming more and more serious. Therefore, strengthening the awareness of lightning protection, doing a good job in lightning protection and disaster reduction, and minimizing disasters have been paid attention to by all walks of life and more and more people.

Second, the counselor publicizes to the students 10 ways to avoid outdoor lightning strikes.

Lightning usually hits the spire of the tallest outdoor object, so isolated tall trees or buildings are often the most vulnerable to lightning. People should abide by the following rules when working in lightning to ensure safety.

1, don't stay on the platform of high-rise buildings in thunderstorm weather, and don't enter isolated shacks, sentry boxes, etc. In the open air.

2. Stay away from the exposed water pipes, gas pipes and other metal objects and power equipment in the building.

3. It is not advisable to hide under the big tree during a thunderstorm. If necessary, you must keep a distance of 3 meters from the trunk, squat down and tilt your legs.

4. If there are ants crawling away on the head, neck and hands during thunder and lightning, and the hair stands up, it means that lightning is coming. Get down on the ground quickly to reduce the risk of being hit by lightning, and take away the metal ornaments, hairpins and necklaces you wear.

5. If you encounter a thunderstorm outdoors and have no time to leave tall objects, you should immediately find some dry insulation and sit on it with your feet crossed. Don't put your feet on the ground outside insulation, because water can conduct electricity.

6. When avoiding thunderstorm outdoors, be careful not to hold the ground with your hands. At the same time, put your hands on your knees, keep your chest close to your knees, and keep your head as low as possible, because your head is more vulnerable to lightning than other parts of your body.

7. When you hear thunder within a few seconds after seeing lightning outdoors, it means that you are in a dangerous environment near a thunderstorm. At this time, you should stop walking, put your feet together and squat down immediately. Don't get involved with people. It is best to use plastic rain gear and raincoat.

8. In thunderstorm weather, it is not advisable to open an umbrella or hold high badminton rackets, golf clubs and hoes in the wild. Not suitable for outdoor ball games. It is very dangerous to play golf and football in thunderstorm weather. It is not advisable to stay on the water surface or water edge; It is not advisable to wash clothes, fish, swim or play by the river.

9. In thunderstorm weather, it is not advisable to drive a motorcycle, ride a bicycle or run fast in the rain, because the greater the stride of the body, the greater the voltage, and the easier it is to hurt people.

10. If you see the high-voltage line being broken down by lightning outdoors, you should be vigilant at this time because there is a step voltage near the breakpoint of the high-voltage line. People nearby must not run at this time, but should jump off the scene with their feet together.

Third, consolidate and improve.

Let the students exchange their feelings about this class, and then assign representatives to summarize the gains of this class.

Lesson 3 1: when it thunders, close the doors and windows, try not to make phone calls, answer phones, mobile phones or surf the internet, and unplug the metal wires that may lead to lightning, such as the power supply of household appliances, telephone lines and TV closed wires.

2. Keep away from the metal water pipes and sewer pipes connected to the roof indoors, and do not pull the wires to the doors and windows.

3. In case of sudden thunderstorm and stiff standing, kneel with your feet together and take off metal objects, hairpins, necklaces, etc. Don't get involved with people. It is best to use plastic rain gear, raincoat, etc.

4. When avoiding thunderstorm outdoors, be careful not to hide in dangerous places such as caves, boulders, cliffs, huts and solitary trees.

5. Pay attention to the weather forecast in summer, try not to go out in thunderstorm weather, and make emergency preparations in advance.
