1. The power of knowledge broadcast draft 150 words

Radio script: knowledge is power

Students, you must envy those powerful people in fairy tales, and you must fantasize that you can become conquerors and invincible heroes. Let me tell you, the key to realize this wish is to learn culture well and master modern scientific knowledge.

The famous British philosopher Bacon said that "knowledge is power". This sentence has been proved by countless facts.

Without understanding geology, people will not know the treasure under 9.6 million square kilometers of land; If you don't know information science, you will become a deaf and blind modern man; Without understanding genetic science, it is impossible to overcome genetic barriers and meet the needs of human survival.

Building the motherland needs knowledge, managing the country needs knowledge and building our schools needs knowledge. People without scientific and cultural knowledge can hardly survive in modern society; Countries that do not attach importance to science and technology will fall behind and be beaten. Marx, a proletarian revolutionary tutor, went to the library to look up information and write Das Kapital every day, leaving two deep footprints under his seat. Lu You, a poet in the Song Dynasty, loved reading all his life. In his room, books are packed in cabinets, piled on tables and spread on beds. He sleeps with a book on his pillow. He left more than 9,000 poems to later generations and became a famous patriotic poet in China. There is no doubt that the achievements of others are inseparable from the spirit of learning.

Students, history tells us that China needs science and technology to take off; Times tell us that catching up with advanced countries in the world is inseparable from science and technology; The red scarf on the chest is also constantly reminding us that the motherland needs a knowledgeable and literate successor. Let's start today, study hard and climb to the peak of world science and technology step by step!

3. How to make the fifth-grade science and technology broadcast draft, 100 words.

Delete words by yourself

In recent years, we have seen the rapid development of science and technology in our great motherland, which makes me feel extremely proud. I am a China native. I remember a long time ago, there was almost only one purpose of mobile phones, that is, making phone calls. But a few years ago, mobile phones have changed a lot, not only in appearance, but also in many uses. They can be used to take photos, have meetings, surf the Internet, send short messages and so on, which makes our life more convenient and makes me more aware of the power of technology. However, I am just a fledgling student. But I want to think about technology and the future from the perspective of a student.

From the dream of genetic engineering to the promise of nanotechnology to ensure that you don't have to wash clothes; From the warmth of artificial intelligence "give you a lovely robot dog" to the wonder of transgenic technology "let mice grow human ears", new technologies are constantly being born, and every discovery of new technologies will make people ecstatic, because these new technologies are gradually improving our lives and let us know ourselves better. In the near future, China completed the whole genome sequencing of SARS virus for the first time, which is recognized as the most harmful disease in the world at present. But why can't other countries finish it first, while our country has just finished it? Quite simply, this shows that our country is not behind others, nor worse than others. Looking back on our motherland's past, from a country that has just started reform and opening up to a big country with a leading scientific and technological level, our motherland has experienced many ups and downs and experienced many difficulties and bumps, but our motherland has survived because we firmly believe that science and technology can not only change our destiny, but also change our future.

For our generation, the general feeling given to the society is a strong sense of competition and sufficient motivation to learn. Popular science knowledge is the focus of our attention, Einstein, Hawking and Bill Gates are the stars in our minds, and computer science, modern physics and chemical kinetics are influencing us all the time. We have understood the importance and universality of science and technology.

Although the prospect of technology creating a new life is fascinating and fascinating. But in the final analysis, it depends on the concerted efforts of all of you, Qi Xin. As the backbone of the future construction of the motherland, the burden on our generation of young people is really not light, and new opportunities are always accompanied by risks and challenges. However, we will not give up easily. We swear to our predecessors with our youth that we will never live up to their hopes.

Looking back at the course of civilization, it is the light of science and technology that sweeps away the darkness of ignorance in human history, and it is the fire of science that ignites the burning hope in human hearts; Science and technology support civilization, science and technology create the future, and the future is in our hands. Let's become explorers of knowledge, let's roam on unknown roads, and let's use our creativity to make the world we live in a better place.

China's environmental situation 1, air pollution is soot pollution.

2. Acid rain is mainly distributed in the south of Yangtze River, east of Qinghai-Tibet Plateau and Sichuan Basin. Acid rain pollution is the most serious in central China.

3. The water in rivers, lakes and reservoirs is generally polluted to varying degrees. Except for some inland rivers and large reservoirs, pollution tends to increase, especially in the waters near industrialized towns. 4.

9, urban surface water pollution is generally serious, showing a worsening trend. Most rivers are polluted to varying degrees.

10, two thirds of the rivers and more than100000 hectares of farmland in China have been polluted. III. Theme of Environment Day over the years 1974: There is only one earth 1975: Human habitation 1976: Water, an important resource of life 1977: Concern about ozone layer destruction, soil erosion, soil degradation and deforestation 1978. 1980: New Year 10, New Challenge-Preventing Toxic Chemical Pollution 1982: Commemorating Stockholm Human Environment Conference 10, Raising Environmental Awareness 1983: Managing and Treating Hazardous Wastes and Preventing Acid Rain/kloc- Due to people's insufficient expectation of the negative impact of highly developed industries and unfavorable prevention, three global crises have resulted: resource shortage, environmental pollution and ecological destruction. People are constantly discharging pollutants into the environment.

However, due to the diffusion, dilution, redox and biodegradation of atmosphere, water and soil, etc. The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification.

If the discharged substances exceed the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, thus leading to environmental pollution. There are many kinds of environmental pollution: according to environmental factors: air pollution, water pollution and soil pollution.

According to human activities: industrial environmental pollution, urban environmental pollution, agricultural environmental pollution. According to the nature and sources of environmental pollution: chemical pollution, biological pollution, physical contamination (noise pollution, radioactivity, electromagnetic wave) solid waste pollution, energy pollution.

Environmental pollution will cause direct damage and influence to the ecosystem, such as desertification and forest destruction, and will also cause indirect harm to the ecosystem and human society. Sometimes this indirect environmental impact is more harmful than the direct harm caused at that time, and it is more difficult to eliminate. For example, the greenhouse effect, acid rain and ozone layer destruction are all environmental impacts caused by air pollution.

This kind of environmental effect from environmental pollution is lagging behind, and it is often difficult to be detected or predicted when pollution occurs. However, once it happens, it means that environmental pollution has developed to a very serious degree. Of course, the most direct and easily felt consequence of environmental pollution is to reduce the environmental quality of human beings and affect their quality of life, physical health and production activities.

For example, urban air pollution causes air pollution, and the incidence of people is rising. Water pollution worsens the quality of water environment, and the quality of drinking water sources generally declines, threatening people's health and causing premature birth or malformation of fetus. Serious pollution incidents not only bring health problems, but also cause social problems.

With the intensification of pollution and the improvement of people's awareness of environmental protection, disputes and conflicts between people caused by pollution have increased year by year. At present, environmental pollution problems have appeared in different degrees all over the world, including atmospheric environmental pollution, marine pollution and urban environmental problems.

With the globalization of economy and trade, environmental pollution is becoming more and more international. In recent years, the problem of transboundary movement of hazardous wastes is a prominent manifestation in this regard. Protecting the earth, since I started, Mother Earth has nurtured countless generations of children and grandchildren through the ages with sweet milk.

It turned out that she was beautifully decorated by junior students. However, now human beings have tortured her to death for their own interests.

There is only one earth for mankind; The earth is facing a serious environmental crisis. "Save the Earth" has become the strongest voice of people all over the world.

I feel heartache for the deterioration of the surrounding environment. I think: if teenagers, as future successors, don't understand the composition of human environment and the seriousness of environmental problems, ignore the laws and regulations on environmental protection, don't enhance their awareness of environmental protection, and don't consciously fulfill their obligations to protect the environment, our lives will be destroyed in their own hands, and God will severely punish us. To this end, I am determined to start from myself, protect the environment, protect our homeland and be a guardian of the environment.

In the past year, I actively participated in the tree planting activities carried out by the school, led the class cadres of our Senior One (6) Squadron to set up a "Green Angel" tree planting and green protection group, encouraged the team members to adopt a small sapling on campus, and used their spare time to decorate it carefully, laying the foundation for it to grow into a towering tree. In the signature activity of "Let the Earth Be Full of Life" organized by the school, I solemnly signed my name on it, writing down my determination and expectation for environmental protection and my vision for a better future.

I actively participated in the prize-winning essay-writing activities held by the school in World Environment Day, carefully consulted and collected various materials, conducted social surveys, and wrote articles on environmental governance. I often take part in environmental protection lectures organized by the school, watch environmental protection videos, actively participate in environmental protection knowledge quiz activities, and fill in each question carefully. I participated in the website construction of the "Red Scarf Green Team" and posted a lot of environmentally friendly things on it.

6. The broadcast draft of scientific knowledge (300 words) had better be filmed.

First, the opening song "Planting the Sun" prologue: (female) teacher (male) classmate, (qi) Hello everyone! M: With this cheerful opening song, Radio * * meets you again.

I am the host. Woman: I'm the host.

M: Today, the columns we arranged for you include campus news, our songs, world tips, teaching you a trick, and exhibitions at home and abroad. 1. Campus News Woman: We are the masters of the school, and we care about our campus.

Please listen to the campus news next. Second, our songwriter: songs are our favorite.

Today, we arranged the episode "Bai Longma" in The Journey to the West cartoons for you. (Playing songs) Third, the world is clean and tidy: the world is big and there are no surprises.

M: Next, we will arrange a small column about understanding the mysteries of the world, "World Spare Parts". W: Turkish hairdresser Demir's bow-cutting method has attracted many customers.

Man: strange fish can walk. Fish has "legs" when walking, teeth in its mouth, smooth and hard skin and fine bone spurs? Have you ever seen such a fish? Zhang Zhonggang, a citizen of Zunyi City, Guizhou Province, recently caught a strange fish near a small pond in the lower reaches of Xiangjiang River not far from home. This fish weighs about four times. Touch any part of the fish with your hand, and all the fins of the fish will spread out immediately, and the tail fin will start swinging from side to side in a small range, and the four fins under your body will slide forward in tandem.

Four, teach you a trick: in life, there are many good tricks that can make you get twice the result with half the effort or get out of trouble. We have arranged a small column for you to teach you a trick.

M: Human resources are limited. We need to learn to save money in life. Today, I will teach you a few tips to save electricity. Woman: Don't stand by for home appliances.

Television, air conditioning and other household appliances, when the power switch is not turned off, the internal infrared receiving remote control circuit is often in standby state and still consumes power. M: The water dispenser is powered on almost all the year round, and it is rarely turned off even during working hours and rest hours. This will not only waste electricity, but also affect the normal use of water dispensers.

W: Under the same brightness, energy-saving lamps save 80% electricity compared with incandescent lamps and have a longer life. When watching TV, only turn on 1 watt energy-saving fluorescent lamp, which not only saves electricity, but also has ideal viewing effect.

We should also turn off the lights and destroy the ever-burning lamps. 5. Popular Science Knowledge Male: Popular Science Knowledge-Why should primary school students pay special attention to sitting posture Female: Some primary school students like reading or bending over to write, or standing there twisting their bodies and leaning their shoulders? These postures are incorrect and harmful to health.

Man: The correct sitting posture is: torso straight, shoulders straight, head held high, eyes straight, legs vertical to the ground, feet flat on the ground. If you need to work at your desk, the bending part should be in your arm, not your waist or back.

Some pupils like to bend over and bury their heads on the table when reading or writing. If this happens for a long time, the spine will bend and deform. The correct standing posture should be that the whole body is upright, the head is raised, the eyes are looking straight ahead, the chest is slightly forward, the abdomen is slightly retracted, the hands are drooping, the heels are close together, and the toes are separated; Viewed from the side, the ears, shoulders and the greater trochanter (where the upper thigh protrudes) are in a straight line; Seen from the back, the shoulders are balanced and the shoulder blades are symmetrical on both sides of the spine.

Female: Primary school students are in the stage of growth and development. Whether the posture is correct or not has the most significant influence on their bones. Their bones are calcified, and they always grow in any posture.

If you often bend over (bend forward or lean left and right), it will cause various spinal deformity flexion (kyphosis or kyphosis) for a long time. If the sitting posture is correct, the thoracic development is normal, the lungs can breathe freely and the heart is not oppressed, so as to ensure that the internal organs are in a normal position and the physiological processes of the whole body can be carried out normally.

It can be seen that it is very important for primary school students to develop correct posture. M: Happy times are always so short. Let's end today's red scarf broadcast in a beautiful melody.

Thank you for listening. Man: Teacher and woman: Friend: Goodbye.

The ideal of flying-the bud of hope

Each of us is going from childhood to maturity step by step, just like sailing against the water with the brave along a river.

When we were young, we all had some beautiful, beautiful and somewhat naive and unrealistic fantasies, just like colorful pebbles by the river. We were all drunk by those gorgeous colored pottery. Gradually, when we grow up, our eyes shift from pebbles under our feet to the front. At the source of this river, stands a majestic and towering snow-capped mountain, which is fascinating. We call it-ideal. A most beautiful word! ~

Ideal contains our yearning for the future, our hope for the future and our longing for a better future.

Golden childhood, precipitation childhood happiness, precipitation faint fragrance. Just like the old daughter is red, the longer it gets, the more fragrant it gets, and the longer it gets, the less satisfied it is with the aftertaste. When I was a child, my greatest dream was that my parents could buy me more toys and delicious food. Now it seems that I feel how naive I was when I was a child.

When I grow up, I gradually understand: "The ideal does not lie in a delicate flower. It needs our eager eyes to nourish it and our sincere hearts to care for it. "

Indeed, everyone has an ideal, but the key to making this beautiful ideal come true is to look at yourself. Cheer up in failure, work hard in cheer up, and win in hard work. This is the spirit we want. As the saying goes, "Where there is a will, there is a way". I believe that as long as we study hard, be practical and reliable, we will definitely make our ideal come true! ~

Ideal is a stone, knocking out a single spark; Ideal is the lamp that illuminates the road at night.

Ideal is fire, lighting the extinguished lamp; Ideal is the road that leads you to the dawn.

Of course, the ideal is also a kind of motivation, which pushes us forward.

Let's put wings on our ideals and let's fly them together. . . .

The red sun, which shines with enthusiasm, is shocked by cheers one after another.

Panicked into the arms of dark clouds. Migratory birds flying north are because of the hot weather.

The scene of the sky hovers over the playground, missing here and the silent days.

Air is very different from excitement. Trees around the playground are swaying in the autumn wind.

Frequent visits played a symphony of fragrant leaves, as if to match.

Cheerleading teams on the field cheer for the struggling athletes.

This is an extraordinary day. All the students on the field are looking for it.

Always show your style on the stage. What about everything around you? one

Everything is icing on the cake, and her existence is even more brilliant.

It is perfect and worthwhile to make the flowers of her life bloom more brilliantly.

Let's celebrate and cheer for it.

Sunshine always comes after the storm-for the temporary losers in the sports field.

Really, it would be great if life could have a draft and be copied again!

We will write our own life absolutely seriously, perhaps not necessarily better than others.

But it must be better than the first time.

Perhaps, life can't be as beautiful as you think, and the road of life can't be smooth sailing.

People's mood will not be as calm as water forever.

In life, there are successes and failures. Therefore, we should let go of life, perhaps the distance is very slim,

Maybe we will be stabbed by the "fallen thorns in life", but we still have no regrets. Fly,

Even at dusk, it is bound to be full of singing clouds, because we firmly believe that,

It is hypocritical to give up without fighting, and detachment without being tempered by disaster is frivolous.

It is cowardly to escape the wisdom shown.

The sun will not shine forever, there is no constant happiness, and suffering may be a gift from God.

Used to test our will, if so, let's face life with a smile.

scientific popularization

Popular science knowledge is written knowledge that explains various scientific phenomena and theories in easy-to-understand language. For the purpose of popularizing scientific knowledge. Popularization of science and technology refers to the activities of popularizing knowledge of natural science and social science, spreading scientific ideas, carrying forward scientific spirit, advocating scientific methods and popularizing the application of science and technology in a way that is easy for the public to understand, accept and participate.

Popular science covers a wide range, including life science, marine science, environmental science, cosmology science, information science, earth science, energy science, biological exposition, transportation, military science, aerospace and so on. Popular science venues and facilities are important places for the public to popularize education. In order to enable people to better cope with popular science, China has also set up special popular science venues, such as China Science and Technology Museum, Beijing Planetarium, Chengdu Giant Panda Museum, Dalian Forest Zoo, Guangxi Science and Technology Planetarium, Henan Museum, Shanxi Science and Technology Department, Shanghai Natural Museum, Shenyang Science Palace, China Ancient Animal Museum, geological museum, China Science and Technology Museum, china agricultural museum and so on. By the end of 200 1, there were more than 240 science and technology museums in Chinese mainland, including 2 1, 8 comprehensive nature museums, 6 museums established in nature reserves, 5 professional natural history museums11,agriculture, aviation, aerospace, post and telecommunications, railways, Chinese medicine and so on.

The history of human progress eloquently proves that science and technology are the great historical driving force of human progress and social development. As a bridge between science and technology and human society, popular science is an eternal theme in human history.

From the perspective of sociology of science, the popularization of science is a universal social phenomenon, which inevitably has its own "growing point". The growing point of popular science lies in the intersection of nature and man, science and society. In other words, the interaction between natural science and human society has produced scientific popularization, and science and technology and society, as the "soil" of scientific popularization, have nurtured its growth. Scientific and technological progress and social development have provided new growth points for popular science work, which has a fresh vitality, strong sociality and the times. Figuratively speaking, popular science is a "modern civilized drama" with the times as the background, society as the stage, people as the protagonist, science and technology as the content and facing the general public. There are no traditional reserved programs on this stage.

China characteristic popularization of science

Due to China's large population, backward education infrastructure and low per capita education level, the overall scientific literacy level of the public is relatively low. In addition, China is currently a country with unbalanced economic and social development. There are great differences in public scientific literacy between urban and rural areas, regions and occupations. Therefore, the popularization of science in China is a multi-level three-dimensional project, which is richer than the western public's understanding of science, including popularizing scientific knowledge, advocating scientific methods, spreading scientific ideas and carrying forward scientific spirit. Since the founding of New China, popular science has been regarded as a public welfare undertaking, which has been highly valued by * * * and all sectors of society. Established a science popularization management and coordination organization, built a large number of science popularization venues and facilities, and carried out various forms of science popularization activities.

China science popularization legislation

In June, 2002, China promulgated the Law on Popularization of Science and Technology in People's Republic of China (PRC), which is the first science popularization in the world.

Outline of the State Council's National Action Plan for Scientific Literacy in 2006

In 2009, Nanjing promulgated the Regulations on Science and Technology Popularization in Nanjing.
