Reflections on the Earthquake Science Popularization Hand in Hand Activities
In life, work and study, there are always some things or people that make us deeply touched. At this time, you may need to write an insight article to record it. Do you know what issues you need to pay attention to when writing your reflections? The following is my reflection on the Earthquake Science Popularization Hand in Hand activity that I collected for everyone. It is for reference only. Let’s take a look together.
Insights from the Earthquake Science Popularization Hand in Hand Activity 1
When an earthquake strikes suddenly, if we can adopt correct and scientific escape and self-rescue methods, casualties will be minimized. In order to strengthen the safety awareness of school teachers and students and improve self-rescue and mutual aid capabilities, in accordance with the unified requirements of the Education Bureau, Suiping Quyang No. 2 Primary School actively formulated a plan and made full deployment to make full preparations. An escape and self-rescue drill was carried out on the afternoon of xx, xx Activity. This activity mainly consists of two parts: a one-minute earthquake prevention drill under the desk and an evacuation drill after an earthquake. Relevant leaders of the County Public Security Bureau were invited to watch.
First of all, Officer Li from the County Public Security Bureau Police Station explained the common sense of safety prevention of campus violence to all teachers and students of our school. Officer Li combined practical life and vivid examples to talk about safety knowledge, to facing How to carry out self-protection and self-rescue in time when a safety accident occurs, and personally gave a wonderful safety education class to the children
After that, the escape and self-rescue safety drill began. There were students from five classes of fourth grade and six Students in the fourth grade class - the children were studying quietly in the classroom. Suddenly, the signalman sent out: "Earthquake Warning" signal. (school bell) The students quickly picked up their textbooks and hugged their heads, got under the desks, curled up their bodies as much as possible, and lowered their center of gravity. The students in the last row facing the wall squatted in the corner. One minute later, the signalman sent out the "earthquake clearance" signal (whistle): the teacher informed the students that the earthquake had passed and they were now leaving the classroom and entering the emergency evacuation drill. Under the unified organization of the teacher, the children were not anxious or panicked. They covered their heads with books one after another, ran out of the classroom in an orderly and fast manner, and quickly evacuated to the pre-designated location according to the predetermined evacuation route. The evacuation was successfully carried out. Evacuate safely.
Through this disaster prevention and reduction activity, teachers and students’ awareness of disaster prevention and reduction has been improved to a certain extent. At the same time, it has also cultivated students’ moral character of obeying orders and uniting and helping each other in all actions.

The content of my speech today is "What should we do during an earthquake?"
Last week, the school held an earthquake drill. The students took it seriously and actively cooperated with the teacher. However, a small group of students laughed and laughed, thinking that it was impossible for an earthquake to happen to them. In fact, earthquakes occur every day on the earth, about 5 million times a year. Earthquake is as common as wind and rain. It is a natural phenomenon that often occurs, but it is very destructive and often occurs in an instant. This requires us to have awareness of disaster prevention, self-protection, and learn more earthquake-resistant skills.
What should we do if an earthquake occurs during class? We should quickly hold our heads, close our eyes, hide under our desks, turn our backs to the window, and use schoolbags to protect our heads. Obey the teacher's instructions and evacuate in an organized manner to prevent stampede accidents. Do not rush out of the classroom in a panic or jump out of the window to escape.
What should we do if an earthquake occurs at home? We should hide near solid furniture, inside walls, corners, kitchens, toilets, storage rooms and other places with small openings.
What should we do if an earthquake occurs when we visit a bookstore? We should choose a strong pillar or inner corner to squat on the spot, protect our head with our hands or other things, and avoid glass doors, windows, glass showcases or counters. Don't panic and follow the instructions of the on-site staff.
What should we do if we are unfortunately buried under pressure? Try to use bricks, wooden sticks, etc. to support the broken walls to prevent further collapse of surrounding debris to prevent being buried under pressure during aftershocks. Do not use indoor facilities casually, including Do not use open flames, power sources, water sources, etc. When you smell gas, toxic odors or excessive dust, try to cover your mouth and nose with wet clothes, do not scream, maintain your strength, and use knocking sounds to call for help.
To take preventive measures before they happen, students, make your own "earthquake bag" when you go home at noon. First find a schoolbag (it can be an old schoolbag or backpack that has been used before) and put some disaster prevention supplies in it: such as whistles, flashlights, first aid medicines, matches, candles, towels, ropes, blankets, cards with family members' blood types, etc. Wait, you can put two more bottles of mineral water and some solid food (such as biscuits, peanuts). Remember to replace these foods every once in a while, because they will expire if stored for a long time. Then put this "earthquake bag" in a conspicuous and easily accessible place at the door of your home. If a disaster does occur, this "earthquake package" may save our lives.

xx, my mother took me to the Science and Technology Museum to visit the "Earthquake Prevention and Disaster Reduction" science popularization exhibition. Through models, pictures, texts, etc., I learned what an earthquake is and why earthquakes occur? Earthquakes are mainly caused by the cracking and dislocation of rocks deep underground, which sharply release the energy accumulated over a long period of time in the form of seismic waves. It spread in all directions, causing the house to shake and the earth to shake.
It also made me understand that there are some warning signs before an earthquake, such as fish jumping to the surface of the water in panic, and well water having large and small bubbles, and sometimes changing color. Change the flavor.
When an earthquake occurs, stay still and squat down outdoors, protect your head with both hands, and be careful to avoid tall buildings or dangerous objects such as street lights and billboards. If you are indoors, do not jump off the building or go to the balcony. You should quickly protect your head with a schoolbag, hold your head, close your eyes, and hide at your desk. After the earthquake passes, move outside the classroom under the teacher's command. .
After visiting the "Earthquake Prevention and Disaster Reduction" science exhibition, I felt that we should face difficulties with strength and optimism and not be intimidated by them. In normal times, we should learn more about earthquakes and rescue, and be prepared to deal with earthquakes, so that we will not panic when an earthquake occurs.

Natural disasters, including man-made disasters, are people’s biggest enemies. There are many natural disasters, such as earthquakes, acid rain, greenhouse effect, typhoons, etc. Man-made disasters include fires, soil erosion, etc. As far back as ancient times, people had no awareness of prevention and prayed to gods and Buddhas for protection and safety. With the development of society, people know how to use scientific principles and practical methods to protect themselves and reduce disasters that threaten their lives. This article will tell you how to use scientific methods to prevent earthquakes and reduce disasters, protect yourself and your home.
According to surveys, major earthquakes occurred in many places across the country, such as the 1514 Dali earthquake in Yunnan, the 1975 Haicheng earthquake in Liaoning, the 1605 Qiongzhou earthquake in Hainan, the 1786 Nandi earthquake in Kangding, Sichuan, and the 1976 The Tangshan Earthquake in 2008... so many disasters caused heavy damage, especially the Tangshan Earthquake, which killed more than 200,000 people and injured them.
In fact, some disasters can be prevented. There are some warning signs before an earthquake occurs. For example, horses and other livestock will break free from their reins and run wildly; hibernating snakes will rush out of their holes; bees will fly away and flee; dogs will bark, and some domestic animals will break out of the pen and run around; rats will swarm. Moving in groups... These signs can let people know in advance that an earthquake will occur. If these animals are found to have these abnormal phenomena, they must first identify the true and false, and then report to the earthquake bureau so that they can evacuate as soon as possible.
Death is not certain when an earthquake occurs. In fact, there are many ways to save yourself. For example: There is an earthquake and you are trapped under the rubble. At this time, don't move blindly. Be calm. Take your hands out first and slowly move the rubble. Keep your breathing smooth first, and then find a way to breathe and call for rescue. you. If you are at home when an earthquake occurs, you must immediately get into a small room that is hard and has not collapsed to avoid being injured. Also, you should stick to a solid wall or squat at the door to survive after the house collapses to avoid being injured. If you are in the wild, be sure to avoid steep cliffs to prevent falling down the mountain. There is also the need to prevent landslides to avoid sliding down. If you are in school, you must follow the teacher's instructions, hide under the desk, and protect your head. If you are in physical education class, avoid tall buildings to avoid being injured. If you are in a movie theater, hide under the viewing chair to avoid shock, avoid lights hanging on the ceiling and air conditioners, use something to protect your head, and follow the command of the commander to evacuate the scene. If an earthquake occurs in a shopping mall, avoid glass cabinets, goods, billboards, lights and other items. If you are in a bus, hide under a chair or squat down, stabilize your center of gravity, and hold on to the armrests.
Other natural disasters are not as inevitable as earthquakes and are sometimes completely controllable.
Acid rain is called the "god of death in the air" because the exhaust gases (sulfides) emitted by people's factories float into the air. When it rains, they fall with the rain and become acid rain. Acid rain will cause lake water to become acidic and fish and shrimps to die; forests will gradually age; farmland will become barren; once it drips onto cultural relics, precious calligraphy and paintings, it will be corroded immediately... It can be seen how harmful acid rain is to people!
The greenhouse effect refers to an effect in which gases in the atmosphere absorb infrared rays, causing temperatures to rise. It is also very harmful and can cause many people to lose their lives, especially the elderly and children. The greenhouse effect can cause people to suffer from lung diseases such as asthma, and can also cause many diseases, such as encephalitis and high fever. It will also cause droughts, floods, food shortages, and severe property losses in many places.
There are also many natural disasters, many of which are "masterpieces" of human beings themselves. Therefore, we must have this knowledge and not harm ourselves.
Not only natural disasters, but also man-made disasters. Such as fires, mudslides, water and soil erosion, etc., are all unnecessary losses caused by human beings cutting down trees.
Therefore, I suggest that everyone do the following:
1. Protect forests, plant trees, and protect water and soil.
2. Factories should not emit too much waste gas and use inexhaustible solar energy.
3. To protect the ozone layer, cars should not emit exhaust gas.
4. Be careful with fire and don’t throw cigarette butts around.
5. Learn more about earthquake prevention and disaster prevention, and be aware of prevention.
6. Save water and cherish every drop of water.
If these points are done first, the occurrence of disasters will be reduced, or many lives will be saved once a disaster occurs.
To protect our home, the earth, is to protect yourself. Let us take action to jointly prevent disasters and make tomorrow’s earth brighter and more splendid! Insights from the earthquake science popularization hand in hand activity 5
xx I followed the Mingde team to an earthquake prevention and disaster reduction site `Although the training base looks like an ordinary house from the outside, there are many projects inside.
We first went to the first exhibition hall and saw a seismograph (model) invented by Zhang Heng in ancient times. It is a big cauldron with eight dragons on it. There is a bead in the dragon's mouth, facing eight directions: east, south, west, north, northeast, southeast, southwest and northwest. There are eight toads below. Which direction is the earthquake? The beads in the corresponding dragon's mouth will fall into the corresponding toad's mouth, so that you can determine where there is an earthquake.
What impressed me most was the child who saluted the People's Liberation Army-Lang Zheng. He was injured in the earthquake and was rescued by the People's Liberation Army. His left hand was fractured and could not move, but he used his weak right hand to salute the People's Liberation Army with a standard military salute. This scene moved everyone present. During the earthquake, there was a class in class. With the help of the teacher, many students escaped. Four students did not escape and could not escape. They hid under the table and the teacher used his body to protect them. However, when rescuers arrived, the teacher had no signs of life. These four students survived because of the protection of the teacher. This scene moved me...
The commentator also told us that if we are indoors during an earthquake, we should hide under the table as soon as possible or use hard objects. Put it on top of your head and then hide in the corner, which is the "triangle area". We also experienced an earthquake simulation, which was really powerful! So we must remember the escape methods.
Through this event, I learned how to survive an earthquake, and I also felt the heroes’ spirit of selfless dedication and self-sacrifice. I want more people and students to survive the earthquake, and I also want people to know the deeds of those heroes and pay tribute to them!

Disasters are people’s biggest enemies, such as Disasters such as earthquakes, tsunamis, fires, etc. will cause huge losses to people, including human lives. Therefore, we must understand the knowledge of earthquake prevention and disaster reduction and learn to protect ourselves.
The school organized many activities for us to learn the knowledge of earthquake prevention and disaster reduction. For example, we asked the uncles from the fire brigade to explain to us the knowledge of escape in case of fire, and conducted escape drills in case of fire. When fire broke out, use towels. Cover your mouth, stand in line and quickly run from the safe passage to the playground. The school also invited a traffic police uncle to explain traffic safety knowledge to us to avoid traffic dangers.
Some disasters are preventable, and there are some unsafe factors in our schools. For example, the stairs in the school are crowded into a pot of porridge every time you go downstairs, which is the most likely to cause a pagoda incident. The fan in the classroom, when turned on to the maximum, would swing back and forth on the roof, as if it was about to fall. Every time a strong wind blows and the classroom door is closed hard, the glass on the door can be shattered. If you are chasing and fighting in the corridor, it is easy to fall and injure the other person. These are all unsafe factors around us and they are all preventable. Take a look at the following items:
1. Don’t chase and fight in school.
2. When going downstairs, go down one by one and don’t crowd together.
3. Don’t close the door hard. When the wind blows, use a chair to hold the door.
We must protect the public facilities of the school. To care for the school is to care for ourselves and make our school better! Reflections on the earthquake science popularization hand in hand activity 7
As we all know, science popularization Knowledge is very important knowledge that every teenager should know. In order to resolutely implement the practical activities of the Science and Technology Festival, every student in our class watched the earthquake science knowledge lecture on xx, xx.
Earthquakes are terrible natural disasters that are out of control once they occur. This is our first view of earthquakes. But today, after we watched Teacher Tang Feng’s popular science lecture, we have a new understanding of earthquakes.
Teacher Tang Feng first said that earthquakes are also called earthquakes and ground vibrations. For example, the idiom that we are all familiar with: This is where the earth shakes and the mountains shake. In recent years, the earth has been particularly unstable, with approximately 5.5 million earthquakes occurring every year. Five and a half million times, what a huge number. At first, everyone thought it was incredible, but Teacher Tang Feng told us about the magnitude of the earthquake. There is no sense of earthquake below level 3, and only instruments can detect it. Well, wow, everyone breathed a sigh of relief.
Teacher Tang Feng’s tone became solemn and he mentioned the Tangshan Earthquake, Wenchuan Earthquake and Yushu Earthquake many times. These are devastating earthquakes. Speaking of the Yushu earthquake, Teacher Tang Feng mentioned in passing that devastating earthquakes would also bring a series of disasters: mudslides, fires, floods, toxic gas leaks... This is simply terrible.
However, earthquakes also have precursors. For example, spring water will become muddy, bubble, turn over, heat up, change color, change taste, rise suddenly, fall suddenly, deform the well hole, and the spring source will suddenly dry up or gush out, etc.
However, Wenzhou where we are located is not in the earthquake zone, so there is no need to be afraid.
But if an earthquake really comes, it is possible. If it does come, how should we save ourselves? Teacher Tang Feng told us that we only need to remember four sentences: Don’t be anxious when there is a big earthquake.
When there are many people, find a hiding place first, stay away from the danger zone, and conserve your energy if you are buried.
Soon, the lecture ended. This interesting and exciting lecture explained to us the basic knowledge of earthquakes. This popular science education lecture was really good. Insights from the earthquake science popularization hand in hand activity 8
xx, my brother and I went to the Shaoxing Science and Technology Museum to visit the science popularization exhibition with the theme of "Earthquake Prevention and Disaster Reduction". This exhibition mainly introduces us to the knowledge about earthquakes and fires, earthquake prevention and disaster reduction, and the correct methods to deal with other natural disasters in an intuitive form. We also watched a free 3D movie. This visit gave me a lot of knowledge about "earthquake prevention and disaster reduction", and the harvest is not small!
The earthquake has brought us a lot of harm. For example, lifeline damage, casualties, fire, surface damage, house collapse. The greatest damage caused by earthquakes is casualties. In 1558, there were more than 830,000 casualties due to earthquakes, which was the most casualty year in the world; the Tangshan earthquake killed more than 242,000 people, which was the most fatal earthquake in the 20th century. . Earthquakes can also cause massive damage to life such as railroads and pipelines. I remember that on July 28, 1976, a magnitude 7.8 earthquake occurred in Tangshan City, Hebei Province. In an instant, a city with a population of one million turned into rubble, causing 242,000 casualties and more than 164,000 people being seriously injured. It brought huge losses to human daily life and economic development and shocked the world. However, without the changes in the movement of the earth, there would be no beautiful and colorful world like ours!!! The rocks after the earthquake are books that record history. There is a kind of rock called alkaline fluid rock, which is produced in Tianchi, Jilin. Its origin is in the magma during volcanic eruptions. The separated volcanic gas is 'frozen' in the pumice, and the bubbles account for more than 70% of the total rock, so it can float on the water, so it is called pumice.
After visiting this popular science exhibition, I understood a truth. When facing disasters, scientific understanding and facing them correctly are the abilities that each of us should have. Many times, a little more common sense can save a life. The earthquake refugees are so brave. They rushed to save their lives, protect their families, and get a complete and happy family. We should also lend a helping hand to help the suffering people. Here, I also want to say loudly: "In the face of the earthquake , I will be a little warrior.”
