Thoughts on earthquake prevention and disaster reduction _ Chapter 65438 +0:
On the eve of "Disaster Prevention and Mitigation Day" in China on May 12, on the morning of May 9, our students from Red Star Road Primary School Science Society, led by Teacher Wang, came to Hefei Science Museum for Earthquake Prevention and Mitigation with curiosity and knowledge.
When we first arrived at the Science Museum, the students were attracted by the huge globe outside the museum. Everyone keeps pointing and wanting to travel around the world. As soon as we entered the museum, we seemed to have entered the magic science museum. First of all, we saw the seismograph invented by Zhang Heng, a scientist in the Eastern Han Dynasty. The students gathered around. Seismographs are exquisite and magical. In ancient times, it was used to know where the earthquake happened. On the wall on the right is a huge map of the world, which is our common home. The narrator's aunt took us through just for sightseeing. She introduced some major recorded earthquakes and disasters in China. There are many exhibition boards and models. Before the "Mystery of Earthquake" exhibition board, we learned about the propagation mode of shear wave and longitudinal wave of earthquake and the damage to rock stratum through handle operation. In the domino window of the earthquake, we show the scenes of various natural disasters caused by the earthquake, as well as modern instruments for monitoring the earthquake and videos introducing the internal structure of the earth. The most amazing thing is the earthquake experience house, where students feel it for themselves.
The narrator's aunt kept telling us a lot about the earthquake. How did the earthquake happen? Why is this happening? And the disaster it brings, what preventive preparations should be made at ordinary times? What should I do if the earthquake comes? Aunt also introduced the main fault zones and earthquake-stricken areas in Hefei with sand table demonstration, asking us not to believe in earthquake rumors, but to believe in science.
Through this visit, I have learned more about the earthquake. When we face natural disasters, we must plan ahead, face them scientifically, and strive to minimize them.
Thoughts on earthquake prevention and disaster reduction _ Chapter 2:
Living on the earth, human beings will inevitably encounter some natural disasters, such as earthquakes, floods, tsunamis and so on.
I just learned a lot in Shaoxing Science and Technology Museum. Let's learn about the earthquake! Earthquake is the constant movement of matter in the earth, which will exert great force on rock formations. When this force accumulates to a certain extent, it will cause the rock stratum to rupture sharply, release huge energy and produce strong vibration. This is an earthquake. Earthquakes are divided into three categories: tectonic earthquakes, volcanic earthquakes and subsidence earthquakes.
When an earthquake occurs, you should choose to squat or get down in an open place, don't run around, don't go back indoors, avoid crowded places, and avoid tall buildings and tall supports or hangers. Be sure not to cross the narrow alley near the high-rise building and avoid the earthquake under the overpass, so as not to be injured by the falling building. If buried in the ruins, the radio can help us know the disaster situation in time and get rescue information. In the dark, a flashlight can bring light and self-confidence, and the sound of blowing a whistle or knocking on metal can spread farther and save physical strength effectively.
The earthquake is terrible, but as long as we understand it carefully, it won't be so terrible. Moreover, science is becoming more and more advanced, and strengthening the seismic capacity of buildings is also an effective way to keep disasters away from us!
Nowadays, the natural landscape around us is the result of geological movement. Without the movement and change of the earth, we would not see the beautiful and colorful world today.
Thoughts on earthquake prevention and disaster reduction _ Chapter III:
Today, I am very happy, because the "Little Newton" Science Society organized us to visit Hefei Science Education Center for Earthquake Prevention and Disaster Reduction. Under the leadership of Wang Yuanyuan, the members and parents of our association came to Hefei Science Education Center for Earthquake Prevention and Disaster Reduction with great interest. There, we learned the basic knowledge of earthquakes and improved students' ability to prevent earthquakes and reduce disasters.
As soon as we entered the science museum, an aunt, an interpreter, enthusiastically showed us around. First, we came to the preface hall. On the left side of the preface hall is Zhang Heng seismograph. It is shaped like a wine jar with eight directions on it. There is a dragon ball in each direction, and there is a toad under each dragon ball. According to the commentator's aunt, it was invented by Zhang Heng in the Eastern Han Dynasty. It is a masterpiece created by ancient scientists in China and the first seismograph in the world. If there is an earthquake, the copper beads in the Longkou facing the earthquake direction will fall into the toad's mouth, so the direction of the earthquake can be measured. It is said that an earthquake in western China was successfully predicted by this instrument at that time, which was earlier than the earthquake history recorded by instruments in western countries 1000 years ago. I curiously touched the fuselage of the seismograph for a while, and then touched its faucet. After listening to the commentator's words, I marveled at the cleverness of the ancients in China and sincerely admired them.
Then, we crossed the visiting area and entered the museum. During my recent visit, I saw many major earthquakes recorded in history and tragic scenes of family death and separation. Then we came to the knowledge experience area. First, I learned the earthquake knowledge recorded in the history books with a virtual book flipper, and then I took part in the interactive model game and learned the basic knowledge of the earth plate, seismic waves, crust and faults. On the journey to the center of the earth, several good friends and I also learned about the crust, mantle and core through video.
What excites me most is the experience of the earthquake experience house. My classmates and I waited in line to enter the experience room and watched educational videos. At this time, the room was suddenly dark, and the ground first fluctuated up and down, then swayed from side to side, accompanied by lightning and thunder. The immersive shocking experience made many students cry. After the end, the commentator told us that this was actually just a simulation, and the real earthquake was much more violent and lethal. Only by mastering the correct shock-absorbing posture and space can we escape from death when danger comes.
Then the mediator aunt took us to the family earthquake drill hall and taught us how to take correct emergency measures. She told us that when an earthquake happens, we should keep calm and avoid the danger nearby. We can temporarily take refuge under hard furniture or in the inner corner, or move to places with many load-bearing walls and small rooms such as kitchens and bathrooms. After the earthquake stops, evacuate to a safe and open place quickly. The posture adopted by the body is: squat or sit down, curl up as much as possible, lower the center of gravity of the body, and grasp the solid objects around. Pay special attention to protect the head, neck, eyes, nose and mouth, protect the head and back neck with your hands, or put things around you, such as pillows, bedding and schoolbags, on your head.
Finally, we came to the terrain sand table in Hefei. According to the commentator's aunt, although there are nine fault zones in Hefei, there are not many earthquakes in Hefei. The maximum earthquake is 5. 1, and earthquakes of magnitude 5 or above will be destructive. So she told us not to worry, not to panic and not to listen to rumors at will.
During this visit, we not only saw colorful images and models, but also personally participated in interactive simulation experiments, and personally experienced the earthquake experience house and family simulation earthquake drills, which benefited us a lot. We have not only increased our knowledge of earthquake prevention and disaster reduction, but also learned the methods of emergency avoidance, improved our abilities of earthquake prevention, shock absorption and emergency self-rescue, and enhanced our ability of self-protection. If there is such an activity next time, I will take an active part.
