Scene: (about 8 people) Music begins, voice-over, dancing with the music "Blue Love".
Voice-over: Blue sky, vast land, boundless sea, green forest … The earth is beautiful because of them.
The flowers on the land sway gently with the wind, as if immersed in the song of the wind; The wind is floating in the sky, as if attracted by the blue sky; The green forest echoed with the songs of birds, as if in a dream paradise; White sailboats sail on the boundless sea, shining like the stars in the sky that day.
Life on earth thrives in this colorful paradise. The thin spring rain brings warmth. Everything on the earth seems to be awakened by the spring rain, and is busy for the peaceful spring, adding life to the earth.
Scene: In a laboratory, grandpa, an old urchin, is busy doing experiments.
Child (4 people, one of whom rides a bike): Hello, grandpa, the old urchin. It's the weekend. I'm glad I can come to see you again.
(One person walks to the computer)
Grandpa: Hello, children.
Grandpa, what are you doing?
Grandpa: I'm analyzing the soil of the earth.
B: Grandpa, do you think the earth we live on is the most beautiful planet in the universe?
Grandpa, the old urchin (put down his work and say affectionately, you can use the music of blue love): Yes. According to the astronauts who were lucky enough to fly into space, when they roamed in the sky, they looked at the earth from a distance and saw a crystal-clear sphere with alternating blue and white lines and a thin water-blue "sand coat" wrapped outside. The earth, the mother of human beings and the cradle of life, is so beautiful, spectacular and amiable.
Scene: A student sings "My home has a globe". Jump on the stage
Health: Grandpa, old urchin, I took part in the competition today and won the first prize. Congratulations, everyone! !
Everyone: Really? Singer, sing for us.
The students cleared their throats and sang songs accompanied by music.
The student (younger) clapped his hands and asked, It's really beautiful. What does this song mean? Why is the earth green?
Oh, the pollution on the earth is too serious now! Do not believe, you see:
(Turn on the computer to view relevant pollution information)
People always think that the land, sea and air resources on the earth are inexhaustible, so they never worry about sending tens of millions of tons of waste gas to the sky and dumping hundreds of millions of tons of garbage into the ocean. Everyone thinks the world is so big. What kind of waste is this? We were wrong. In fact, although the earth is large (with a radius of more than 6 300 km), creatures can only live in the range from 8 km above sea level to 1 1 km below sea level, and 95% of creatures can only live in the middle range of about 3 km. People wantonly pollute this limited living environment. If we still ignore the warnings of experts, we will definitely be reduced to the point where there is no half an inch of pure land to live in.
More importantly, do you think this is just a problem of pollution? Resources are also in short supply. About 654.38+0.7 billion people in the world are threatened by the lack of drinking water. 90% rivers in China are seriously polluted. Of the 45 major proven mineral resources, only 23 can meet the demand by 2065.438+00, and only 6 can be used by 2020 ... The per capita non-renewable resources in China are far below the world average, and most of them are less than half of the world average. China's forest coverage rate is about 9%, ranking behind the top 100 in the world, with a per capita forest area of 0. 1, less than110 of the world's per capita forest area. China is one of the countries with the largest area, the widest distribution, the fastest spread and the greatest harm of desertified land in the world. China's per capita water resources are only 2200m3, which is equivalent to the world average of 1/5, the United States of America 1/6, India 1/8, Canada 1/60, and the world ranking 122, ranking the world/kloc-22. More than 300 cities in China lack water; The industrial output value of these more than 300 water-deficient cities accounts for 70% of the country; Among more than 300 water-deficient cities, 1 10 is seriously short of water, and 50 of them are "critical";
The students exclaimed: Oh, my God. This is our earth?
Grandpa old urchin: Yes, the earth is seriously short of resources. We should save energy!
The student asked (thinking): Grandpa, old urchin, you said the universe is so big. Can we move to another planet?
Grandpa: What do you say?
You see, we live in the solar system. There are nine planets in the solar system: gold, wood, water, fire, earth, heavenly king, Neptune and hades. Can people live on those planets?
Yes, there are so many planets that we can move up. Now China's space industry is developing rapidly, and a manned space shuttle is launched. I believe that in the near future, we will definitely go to other planets.
Grandpa: Children, your ideas are very good. Come on, let's go to the simulation lab.
(props conversion can be arranged in astronomy)
Robot: I am a robot 10 1. Welcome to the Cosmic System Simulation Laboratory.
Grandpa:No. 10 1, please take your children to travel in space and explore whether there are planets suitable for human habitation in the solar system.
The music "Starry Sky" began, and models of several planets were designed to show and rotate.
No. 10 1: Welcome to travel in space aboard Discovery. As we all know, if there is life on a celestial body, the following conditions must be met: 1, and the temperature suitable for living organisms is between MINUS 50 degrees and MINUS 1.50 degrees Celsius. 2. Necessary moisture; 3. Atmosphere with proper composition; 4. Sufficient light and heat.
Mercury in the solar system is closest to the sun, with a temperature as high as 300 to 400 degrees Celsius. Venus is a planet with high temperature, lack of oxygen and water, and strong sunlight radiation. Jupiter, Saturn, Uranus, Neptune and Pluto are far away from the earth, and their surface temperatures are all below-140 degrees Celsius, so there can be no life.
Mars and the earth have many similarities, but the spacecraft found that Mars is a very dry planet, with water vapor content only 1% of the desert area of the earth, and the atmosphere is very thin, and there is no magnetic field, so it is difficult for life on Mars to survive.
Unfortunately, there are no planets suitable for human habitation in the solar system.
Scientists have proved that there is no second planet suitable for human habitation at least within 40 trillion kilometers centered on the earth.
(Music begins "Dream"))
Everyone: well, it seems that we can't expect to destroy the earth and then move to other planets.
Can't we just sit back and wait? Stupid people, look what we have done.
Grandpa: Children, there is only one earth. If it is destroyed, we have nowhere to go. Don't be dejected and despondent, as long as we act, the earth will still be full of vitality and vitality.
(Music stops)
Everybody: Is this true? Grandpa, are you kidding?
Grandpa: How could Grandpa lie to you? But think about it. How can we protect the earth?
Students answer directly (Allegro form)
Scrub the furniture without detergent.
Keep warm and prevent heatstroke, and use less air conditioning.
Remember to save electricity when turning off the lights.
Wash your own clothes by hand and try not to use the washing machine.
C: A small handkerchief with a stuffed pocket will help you when you are in trouble.
Abolish disposable tableware and reduce white pollution and garbage.
D: Don't take the bus if you can walk. Really?
(People ask) What should I do?
Find a bike to ride (on your own car).
(that is, hahahaha)
Singing children: private cars, polluted air, more crowded roads.
Don't take the elevator if you can take the stairs.
Small things can be done, and this is the key to energy saving.
A: Talk to the polluting factories and remember to protect the environment.
You will be punished if you go your own way, and you will be fined 770 for planting trees (haha)
Qi: Environmental protection and energy saving depend on everyone. We have been here for generations.
You know all these things, one does not wait, and the other does not depend on it.
Starting from me, starting from now.
Make the sky bluer and the trees greener.
Let the water flow forever and make Qian Shan a garden.
Earth Earth, I love you one by one.
(Song "Tomorrow will be Better")
Grandpa: Little friend, you speak very well. We should seriously protect the earth and its ecological environment. I believe that in the near future, the earth, the common mother of mankind, will better benefit mankind and will last forever.
Prepare some small cards or small productions for the people present, and call for protecting the earth together with the song "Better Tomorrow". )
