Reflections after watching "Earthquake Science Popularization Hand in Hand" 1
The sky has unpredictable winds and rains, and people have misfortunes and blessings. Natural disasters, including man-made disasters, are all enemies of mankind.
Earthquakes are rapid vibrations of part of the ground caused by forces within the earth. It is a natural phenomenon. There are about 5 million large and small earthquakes in the world every year, of which only 50,000 can be felt by people. There are about a dozen powerful earthquakes that can cause destructiveness every year, and there is about one extremely destructive earthquake every year.
In the event of an earthquake, there are ten things we need to know:
1. Hide under tables and other sturdy furniture.
2. Extinguish the fire when shaking, and extinguish the fire immediately when it breaks out.
3. Don’t run outdoors in a panic.
4. Open the door and ensure the exit.
5. In outdoor situations, protect your head and avoid dangerous places.
6. When in department stores or theaters, follow the instructions of the staff.
7. Cars are parked on the roadside, and parking and driving are prohibited in the control area.
8. Be sure to pay attention to landslides, rockfalls or tsunamis.
9. When evacuating, you should walk and carry items to a minimum.
10. Don’t listen to rumors and don’t act rashly.
Some people may be curious, why should we turn off the fire during an earthquake? Because if we do not turn off the fire, it may cause fires, explosions, etc., which will make the danger even greater.
There are precursors to earthquakes. Some microscopic precursors, such as ground deformation, ground stress, geomagnetism, location, etc., cannot be directly detected by people's sense organs. The precursors that can be detected include: abnormal groundwater, abnormal animals, ground light, ground color, etc. Abnormalities in groundwater include: water from dry wells leaks out, rises and falls abnormally and regularly; rainwater becomes turbid, smelly and unpleasant. Animals can also give us some precursors before earthquakes: poultry climbing trees, mules and horses not entering the pen, pigs escaping, rats moving, dogs barking...
Therefore, we must observe more and pay attention to earthquake prevention and disaster reduction !Reflections after viewing "Hand in Hand for Earthquake Science Popularization" 2
Today, several classmates and I made an appointment to go to the Science and Technology Museum to watch the science exhibition. This popular science exhibition helped me understand what an earthquake is. Earthquakes are actually the constant movement of materials within the earth, producing a huge force that acts on the rock formations. When this force accumulates to a certain extent, it will cause the rock formations to bend and deform. Once the rock formations cannot withstand this change, the rock formations will The rapid rupture and dislocation release huge energy and generate strong vibrations. Earthquakes can cause great harm to people, such as mudslides. Sometimes they can submerge entire villages, causing extremely heavy losses to people and houses. Earthquakes can cause large areas of ground to tilt, rise or deform. It will also cause huge damage to lifeline projects such as railways and pipelines. The largest earthquake that has occurred since the founding of our country was the Wenchuan Earthquake. It was a magnitude 8.0 earthquake. The earthquake killed 69,227 people, left 17,923 missing, and injured 374,643 people. Three such thrilling figures made me feel heartbroken for the suffering compatriots. In order to prevent earthquakes from harming more people, our country has established more than 1,000 earthquake observation stations to predict the situation before earthquakes at any time. In addition to these, shelter measures during earthquakes are also very important to us: Never jump off a building or get close to balconies or windows during an earthquake; be careful not to be close to water but not fire; during an earthquake, quickly evacuate to solid furniture, kitchens, toilets, etc. ; Avoid dangerous places, follow instructions, don’t panic, don’t rush out of the exit...
Nature has given us many beautiful scenery, showing its beautiful side. But sometimes nature also reveals its evil and ferocious face. Various natural disasters cause us humans to be careless and suffer heavy losses. This science exhibition on earthquake prevention and disaster reduction taught me a lot about earthquakes, and I benefited a lot! "Earthquake Science Works Hand in Hand" Reflection 3
Earthquakes, also known as earthquakes and ground vibrations, are a natural phenomenon in which the earth's crust vibrates during the rapid release of energy, during which seismic waves are generated.
Earthquakes disrupt our lives. So many mothers have lost their children, and so many children have lost their mothers. In that moment everything changed. People talk about "shock" and their expressions change. What can we do to prevent tragedies from happening again, and how can we minimize the pain caused by ruthless disasters?
In ancient times, when the level of science and technology was low, people could only ask gods for divination. For earthquakes There is nothing we can do. With the development of society and the progress of history, people know how to use their accumulated knowledge to "predict" earthquakes and protect themselves. Farmers in the countryside can save themselves by making their own observations. For example, groundwater suddenly rises, winter snakes appear, and plants bloom out of season. At this time, as an observer and a person involved, you have the responsibility to publicize the situation to the neighbors, but not to spread rumors.
As time enters the 21st century, thatched houses have been replaced by high-rise buildings, and people's lives are most likely to be swallowed up by high-rise buildings during earthquakes. Faced with this situation, we can only call on people to return to nature and try to live in lower houses.
Architects and engineers need to build qualified earthquake-proof houses. Not only the school's teaching building must be earthquake-proof with a magnitude of 8, but all houses must be earthquake-proof. If you are a principal or teacher, in your daily school management and teaching, hold more lectures on earthquake prevention and disaster reduction, and implement emergency drill training. In view of the current actual situation: do not notify the time of emergency drills in advance. Just as it was said during the meeting that emergency drills will be held on Friday afternoon so that students and teachers will be mentally prepared, the effect of the emergency drills will not be very good. What should be highlighted in the drill is urgency and speed.
If you are a teacher, if an earthquake occurs, you must have a calm mind, the talent of a conductor, and arms like Teacher Tan Qianqiu. At this time, you should only have students in your eyes. The world is big, but only my students exist here.
If you are a student, take every emergency drill held by the school seriously and listen to the teacher in everything. Remember not to panic during the drill.
Recently, a trend of "earthquake prevention and disaster reduction" has blown into our campus and into the hearts of each of our classmates. The school organized various activities, such as emergency drills for earthquake prevention and disaster reduction, handwritten newspaper competitions for earthquake prevention and disaster reduction, and essay writing contests for earthquake prevention and disaster reduction. In the process of emergency drills, there are less playful figures and more orderly steps.
Life is precious, and everyone is responsible for protecting it: Life is precious, and earthquake prevention and disaster reduction are everyone’s responsibility. "Earthquake Science Popularization Hand in Hand" Review 4
Earthquake disaster is one of the natural disasters that causes the most serious economic losses and the most casualties in the world. We must strengthen the study of earthquake science knowledge and correctly master the methods of earthquake avoidance, self-rescue, and mutual rescue.
We should listen to earthquake forecasts and learn to read the signs before an earthquake occurs, such as animals flying, fleeing, screaming, etc. We can also prevent disasters from happening by reporting them early, Evacuate.
When an earthquake occurs, the indoor triangular space formed after the house collapses is often a relatively safe place for people to survive. Especially for people in buildings, they should choose places with small spaces such as kitchens and bathrooms, as well as spaces and corners that are not prone to collapse. Places with solid furniture spaces such as tables and beds can be used to absorb shock. Always protect your head with cushions, etc., and do not blindly jump off buildings or use elevators. We must use scientific methods to protect ourselves and our homes and prevent disasters from happening together.
Today is the day of the school’s earthquake prevention drill, and all teachers and students participated. The teacher has explained the specific situation to each of our classmates over and over again. "The earthquake is coming" came the teacher's urgent shout from the radio. We quickly put our schoolbags on our heads and ran out. Every student didn't want to fall behind and ran to the playground like crazy, while the teacher maintained orderly on the side.
We still want to see more Books on earthquake prevention and disaster reduction. Tell everyone around you the knowledge of earthquake prevention and disaster reduction, and let this knowledge be passed on from ten to ten, so that everyone knows how to protect themselves when an earthquake comes and reduce the disasters that earthquakes bring to us. . Let this knowledge accompany each of us and let each of us have earthquake prevention awareness.
We are the builders and defenders of the motherland. Let us act quickly to prevent disasters together. "Earthquake prevention and disaster reduction is everyone's responsibility" Let us *** together wish that tomorrow's earth will be brighter and more brilliant! "Earthquake science popularization goes hand in hand" Thoughts after watching 5
Earthquake, when someone hears these two Just one word makes me feel extremely frightened - it destroys our beautiful home, takes away our precious lives, and brings too many disasters to mankind.
Earthquake prevention means preventing earthquakes from happening. However, currently we do not have this capability. All we can do is disaster reduction, that is, reducing and alleviating the disasters caused by earthquakes. In order to prevent us, the flowers of our motherland, from being destroyed by the earthquake, parents, teachers, and schools have provided us with various related explanations, publicity, and training. My father, who is a construction engineer, told me that when people build houses now, they will use more earthquake-resistant structures and use more steel to make the houses stronger. They will not collapse, collapse less, and collapse slowly during earthquakes. You must be calm during earthquakes. , don't panic and jump off the building. The teacher also vividly told us the warning signs of many animals before the earthquake: rats moved and fled, chickens flew up trees and pigs’ pens, ducks couldn’t get into the water and dogs barked, hibernating snakes came out of their holes early, fish jumped out of the water in panic, etc. If you see these phenomena occurring, you should quickly seek refuge in the nearest square, park or other emergency shelter. The school also invited firefighters to provide us with earthquake training: when an earthquake occurs, if you are at home, you can hide under the bed or table; if you are in a restaurant or movie theater, you can hide under the seat; if you are in a classroom, you can hide under the class. Under the table, and protect your head with a book, bag or hands to prevent head injury. An earthquake lasts about 10 seconds. After a strong earthquake, you should evacuate to a place without buildings to avoid damage caused by aftershocks.
Earthquake is a demon that makes us unable to guard against it. When it comes, it is often difficult for people to escape from its clutches. The 2008 Wenchuan earthquake killed tens of thousands of lives in an instant. However, after the earthquake, people across the country united as one. Earthquake relief has brought sunshine back to so many desperate lives.
While the earthquake brought us suffering, it also tempered our will and aroused our fighting spirit, allowing us to hold our heads high in the face of difficulties, rush forward, cut off the thorns, and leave behind the fragrance!
< p> Life, supreme, needs careful care and infinite care! "Earthquake Science Popularization Hand in Hand" Afterviewing 6Earthquakes are unpredictable. If humans can predict the time, magnitude and region of earthquakes , if we learned to save ourselves, so many lives would not disappear. We are not reconciled. Although we cannot predict the arrival of earthquakes, we can arm ourselves with earthquake prevention knowledge to accurately prevent and reduce the harm caused to us by earthquakes.
Disasters are unpredictable. We can only rely on ourselves to prevent damage caused by earthquakes. Instead of panicking or waiting for rescue, it is better to do our best to save ourselves.
I believe that once an earthquake occurs, the first and most important thing is to stay calm, keep a clear and cool mind, and judge the shaking situation in time. Don’t panic, lose your mind, or panic. This is particularly important.
Secondly, you can assess the situation based on the building layout and indoor conditions, find safe spaces and passages to avoid, and quickly evacuate to a safe place after the first round of earthquake waves to reduce casualties. You can hide under solid furniture, or you can move to a corner with many load-bearing walls and small bays with beams or pillars, the kitchen, or the bathroom to take shelter for a while. Because these places have strong bonding capabilities, especially the pipes that have been treated, they have better support and larger seismic resistance coefficients.
Third, do not hide near doors, windows, stairs, or other places with insufficient load-bearing capacity and prone to collapse. Do not jump off in a panic or get stuck in a crowd. Do not stay near buildings, electric poles, etc. Prevent injuries caused by falling objects from heights. Fourth, keep stairs, corridors and other passages clear at ordinary times, and do not accumulate items in the corridors, which will affect escape in an emergency. Fifth, after becoming familiar with various self-rescue measures, government units, schools, factories and other densely populated units should organize earthquake self-rescue drills so that the knowledge of written self-rescue measures can be trained and practiced skillfully.
Let the whole people take action, seriously study the knowledge of earthquake prevention and disaster reduction, arm yourself with scientific knowledge of earthquake prevention and disaster reduction, and defend your own life! After watching "Earthquake Science Popularization Hand in Hand" 7
On May 12, 2008, there was a major earthquake. In an instant, landslides and ground cracked, homes were destroyed, and lives were lost. The familiar and warm home was torn into mountain-like ruins, the innocent smiling face was deprived of the flower-like childhood, the fresh life was separated from life and death by that moment, and there were many dreams that were cruelly and ruthlessly destroyed. Destroyed and buried. Since 2009, May 12th every year has been set as the National "Earthquake Prevention and Disaster Reduction Day".
Disasters are indeed terrible, but what is more terrible than disasters is ignorance. As primary school students, if we want to cherish life and protect ourselves to the greatest extent, we must learn earthquake prevention and disaster reduction knowledge and disaster avoidance and self-rescue skills. Then, our students should What should you pay attention to when an earthquake occurs?
First of all, the most important thing is to stay calm and not to panic in any emergency. If an earthquake occurs during class, students close to the door can quickly run out of the door. Students in the middle and back rows should hide under the desks as soon as possible and use their schoolbags to protect their heads; students leaning against the wall should stay close to the wall with their hands Protect your head; stay away from windows to prevent injuries from broken glass. Students in the corridor or stairs should find a corner to squat down, protect their heads, stay away from decorations hanging on the wall, and evacuate quickly after the vibration stops. If you are waiting outdoors at the scene, you must not run into a building to avoid danger, and do not stay in dangerous places such as under walls or basketball hoops. Try to gather in open areas. If we find thick smoke, we should cover our mouth and nose with towels and clothes to prevent suffocation from smoke and dust; pay attention to conserving physical strength, do not shout for help, try to find food and water, create living conditions, and wait for rescue. Of course, the chance of encountering a major disaster in a person's life is very small. We must pay more attention to small safety issues and improve our awareness of prevention. I would like to make some requirements below:
First, physical education and extracurricular activities Make adequate preparations before activities, and be careful not to cause violent collisions during exercise to avoid bruises or falls.
Second, keep to the right when going up and down stairs, pay attention to order, and walk softly and slowly to prevent __ incidents from happening.
Third, when you encounter conflicts among classmates, you must be calm and rational. If you cannot resolve the conflict, you must seek help from the teacher to resolve it.
Fourth, now that spring and summer alternate, the temperature difference is large, and it is also the season for germs to breed. Classrooms and dormitories should be ventilated more, and personal hygiene should be paid attention to to prevent the occurrence of infectious diseases.
Fifth, as the temperature rises, we primary school students should not go to rivers or ditches to play, let alone swim in rivers privately, to prevent drowning accidents.
Students, life is beautiful and colorful, but the prerequisite for having all of this is safety.
Therefore, we must always strengthen safety awareness, cherish life, strive to enhance self-prevention capabilities, always pay attention to disaster prevention and reduction, and keep the alarm bell ringing!
