Teaching plan of lightning protection theme class meeting

3 lightning protection theme class meeting teaching plan

In the study day after day, everyone has participated in many theme class meetings, right? The theme class meeting is vivid, compact and harmonious. What preparations should be made to finalize a theme class meeting? The following are three class meeting teaching plans with the theme of lightning protection carefully arranged by me. Welcome to read the collection.

Lesson plan of lightning protection theme class meeting 1 time: 20xx-5- 17 (Friday)

Venue: Class Two (2) classroom

Moderator: Class teacher

Theme: lightning protection knowledge education

Content summary:

Teacher: Summer is the season with frequent thunder and lightning. Thunder and lightning is the discharge process when the charge in the cloud accumulates to a certain extent, which is very destructive and harmful. It is necessary for everyone to know about lightning protection.

First, outdoor lightning protection

1. When going out in a thunderstorm, you can squat down, reduce the height as much as possible, and put your feet together at the same time to reduce the harm caused by stepping voltage. Because when lightning strikes the ground, it will gradually release energy around along the surface. At this time, due to the difference of potential difference, a certain voltage may be generated between the front foot and the back foot of the walking person.

Don't take shelter from the rain under the big tree. Because when it rains, the wet branches of the tree are equivalent to a lightning protection device. If you hold a tree with your hand, it's like touching a lightning rod with your hand. So it's best to stay 5 meters away from the tree when it thunders.

3. When it rains, don't stay near the water (rivers, lakes, oceans, ponds, canals, etc.). ) and depression. You should quickly take shelter from the rain in a dry house nearby. If you can't find a house in the mountains, you can hide under rocks or in caves.

4. Don't stay in the thunderstorm with metal objects, because metal objects are conductive substances, and thunderstorm weather can sometimes play a role in attracting thunder. Carry-on metal objects should be temporarily placed 5 meters away, and then picked up after the lightning stops.

5. Don't touch or get close to lightning protection grounding wires, water pipes, electrical grounding wires, tree trunks and other objects that may be charged due to lightning strike, so as to prevent contact voltage, lightning strike and side attack.

6. In thunderstorm weather, it is best not to answer and make calls outdoors, because the fixed telephone line is introduced from the outside, which is easy to lead to lightning strike, and mobile phone waves can also lead to lightning strike.

7. When going out in thunderstorm and rainstorm, it is best to wear rubber shoes, which can play an insulating role. It is forbidden to run outdoors during a thunderstorm.

Second, indoor lightning protection

1, when it thunders, the first thing to do is to close the doors and windows to prevent lightning from hitting the room directly and spherical lightning from floating into the room. Don't stick your head or hand out of the window.

2. In thunderstorm weather, stay away from metal water pipes and sewer pipes connected to the roof indoors.

3. In thunderstorm weather, try not to make or answer the phone, and don't use your mobile phone to surf the Internet. Unplug the power supply, telephone line, TV feeder and other metal wires that may introduce lightning.

4, into the household power cord insulator iron foot should be grounded, three-phase socket should be connected to the ground wire.

Don't pull the wire for drying clothes and bedding to the window or door to prevent the wire from thundering. Don't collect clothes hanging on wires outdoors.

6. Don't stay away from pavilions, huts and houses in the rain for a long time, pay attention to avoid wires, don't stand under light bulbs, and it is best to cut off power or use electrical appliances.

7. Don't take part in outdoor sports activities, such as running, playing ball and swimming.

Lesson plan of lightning protection theme class meeting Class 2 Class 4 (1) "Disaster prevention and mitigation, lightning protection and mountain torrents prevention" theme class meeting

Activity objectives:

1. By introducing some catastrophic events in the flood season to students, it sounded the alarm and improved their vigilance;

2. Improve students' safety awareness and disaster prevention ability by introducing some precursors and preventive measures to students;

3. Improve students' self-help ability by introducing some self-help and escape methods in the face of disasters. Participants: the class teacher and the whole class.

Activity time: April 20xx 1.

Activity flow:

(A) theme import

"Hello, classmate, it's late spring and early summer. When we wake up from the dreariness of winter and enjoy the sunshine and breeze in spring, we should pay attention to the dangers that belong to this season. Although bursts of spring thunder bring the news of spring, and the light rain in spring is silent, it is not always so romantic and gentle. They may bring lightning strikes or floods.

(2) Lightning and disaster precursors in flood season

(1) It is sultry in the morning, even difficult to breathe, which is generally a sign that a low-pressure weather system is approaching, and heavy rainfall often occurs in the afternoon.

(2) There is a pagoda-shaped ink cloud uplift in the distance in the morning, and there will be a strong thunderstorm in the afternoon.

(3) The weather has been clear and cloudless for many days, especially hot. Suddenly, a small cloud group rises on the windward slope of the mountain, and there is usually a strong thunderstorm at midnight or early morning.

(4) On a hot night, hearing dull thunder not far away is generally a sign of shanghai dawn.

(5) When you see funnel-shaped clouds or dragon-tailed clouds on the horizon, it means that the weather is extremely unstable and thunderstorms and strong winds may come at any time.

Moderator: I hope students can apply this knowledge.

(3), lightning and flood season disaster accident prevention measures

What precautions should we take? See what my lightning protection secret is.

1. Don't shelter from the rain under the big tree. Because when it rains, the wet branches of the tree are equivalent to a lightning arrester. If you hold a tree with your hand, it's like touching a lightning rod with your hand. So it's best to stay 5 meters away from the tree when it thunders.

2. When it rains, don't stay near the water (rivers, lakes, oceans, ponds, canals, etc.). ) and depression. You should quickly go to a dry house nearby to take shelter from the rain and observe whether the house is suitable for shelter from the rain. If you can't find a house in the mountains, you can take refuge under rocks or in caves.

Don't stay in the thunderstorm with metal objects, because metal objects belong to conductive substances.

When it thunders, the first thing to do is to close the doors and windows to prevent the lightning from hitting the room directly and the spherical lightning from floating into the room.

(4), lightning and flood disasters and accidents self-help and escape methods

1. If we are outdoors during the lightning, remember not to stay on the high-rise platform, enter the isolated hut and sentry box, and avoid the thunderstorm under the big tree. If necessary, you must keep a distance of 3 meters from your torso, squat down and put your legs together. It is not advisable to stay on the water surface and water edge.

2. If there are ants crawling on the head, neck and hands when thunder and lightning strike, and the hair stands on end, it means that lightning is going to happen. You should lie on the ground and try to keep your head down, because the head is the most vulnerable part of other parts of the body.

Lightning strike can reduce the risk of being struck by lightning and remove metal ornaments, hairpins, necklaces, etc.

Hail warning signal-precursor

First, I feel hot and cold. The humidity is high, and the solar radiation is strong at noon, which causes air convection and is easy to produce thunderstorm clouds and hail. The second is to look at the cloud color. The color of hail cloud is black on a white background, and then red appears in the cloud, forming white, black and red random moire, and the edge of the cloud is khaki. The third is to listen to thunder. Lei Yin is long, noisy and boring. Like a millstone, there will be hail. The fourth is to watch lightning. Generally, the lightning of hail clouds is mostly horizontal lightning, while rain clouds are vertical lightning. Most of them use the meteorological data and sounding data on the ground and refer to the weather conditions of the day to find reliable forecast indicators. In the long-term struggle with nature, the working people in our country have accumulated rich experience in understanding the law of hail activity based on careful observation of the phenomena of sound, light and electricity in the clouds. According to the different characteristics of thunder and lightning in thunderstorm clouds and hail clouds, there is a saying that there are more thunder and more hail. People from all over the country also observed that before the hail came, the clouds were rolling and rolling very badly. In some places, this phenomenon is called cloud bucket. It is often that two or more cumulus clouds merge and develop after relative movement, and often favorable terrain conditions also strengthen the airflow convergence of this cloud bucket; In addition, when hail clouds come, the sky often appears red and yellow. The bottom of hail cloud is black or gray, and the cloud body is apricot yellow. In some places, there is a saying that the ground is wet and the sky is yellow, and seedlings should be prevented (hail suppression).

Hail classification

According to the maximum hail (general hail) diameter, hail accumulation time and hail accumulation thickness in a hail process, the hail is divided into three grades.

1. light hail: the diameter of most hail is less than 0.5 cm, the cumulative hail time is less than 10 minute, and the hail thickness in the area is less than 2 cm.

2. Moderate hail: The diameter of most hail is 0.5 ~ 2.0 cm, the cumulative hail falling time is 10 ~ 30 minutes, and the hail thickness is 2 ~ 5 cm.

3. Heavy Hail: Most hailstones have a diameter greater than 2.0 cm, the cumulative hail time is greater than 30 minutes, and the hail thickness is greater than 5 cm.

Hail suppression knowledge

1. How to get the hail warning signal?

(1) Call121,96 12 1 or consult the local meteorological station, or get early warning information through TV, radio, newspapers, the Internet, mobile phone messages, etc. ⑵ Check the warning devices of hail warning signals, such as warning signs, warning flags and warning lights. (3) Log on to the meteorological website.

2. What should people do when there is hail weather?

(1) Close the doors and windows, and properly arrange outdoor items that are easily affected by hail and strong wind. If the car is best parked in the garage, of course, it is best to buy insurance for the car in advance.

(2) Residents should not go out at will to ensure that the elderly and children stay at home.

(3) Kindergarten children and school students should be buried in the classroom and suspend outdoor activities.

(4) If outdoor workers want to stop working, they should immediately take shelter indoors.

5] Outdoor personnel should not enter isolated shacks, sentry boxes and other buildings, nor avoid hail in tall chimneys, telephone poles or trees, and try to find a solid place to avoid, especially when encountering lightning.

[6] While preparing for hail suppression, we should also prepare for lightning protection.

3. Agricultural hail suppression measures

(1) Plant grass and trees in hail-prone areas, increase forest area, improve landform environment, destroy hail cloud conditions, and achieve the purpose of reducing hail disasters;

(2) Planting more crops with strong hail resistance and resilience;

③ timely harvest mature crops;

(4) In the hail season in hail-stricken areas, farmers carry hail suppression tools with them in the fields, such as bamboo baskets and wicker baskets, to reduce personal injuries.

(5), class meeting summary

Through today's theme class meeting, we learned a lot about lightning protection, flood control and hail suppression. I hope that all students will pay attention to it. We only have one life, so we can't make fun of it.
