2. Choose the host of the class meeting.
Class meeting process
Passion introduction
(Multimedia demonstration: The earth rotates, then zooms in, blue sky, forest and ocean appear, and finally the theme of this class meeting "Protect the environment, start with me" appears against the background of blue sky and white clouds)
Moderator: The blue earth is surging with the melody of life, and the green world is pregnant with thousands of lives. We need a beautiful environment. But our environment is being destroyed day by day. Let's protect our home together. The class meeting with the theme of "protecting the environment, starting with me" begins now.
Beautiful environment
Moderator: The environment in our motherland is really beautiful. Please enjoy it.
Multimedia shows our motherland: vast plains, dense forests, rolling mountains, towering mountains and rivers, lovely animals, blue sea and fragrant flowers.
Teacher: Students, which scenery is the most beautiful?
Student 1: The beautiful Daxing 'anling and Xiaoxing 'anling have dense forests.
Student 2: There are schools of fish in the blue sea.
Student 3:
Teacher: Our motherland has beautiful rivers and magnificent mountains and rivers. Students, which scenic spots have you been to in our hometown? How do you feel (Wenfeng Mountain, Daji Mountain, Sanshan Island)? Good, beautiful scenery and fresh air make people feel very comfortable. ) These beautiful environments are just a part of our living environment, students, do you know? Environmental pollution is becoming more and more serious, and we are facing great environmental challenges. Protecting the environment is the unshirkable responsibility of each of us.
A worrying environment
Teacher: Now, what is worrying is that such a beautiful environment is being destroyed day by day. Please look at the cartoon "The Fate of Little Fish".
Play the animation: A small fish once swam freely in a clear river. Later, factories and residential areas were built nearby, and sewage and garbage were continuously discharged into the river. The water quality in the river deteriorated, and the little fish and its brothers and sisters had nowhere to escape, and finally they all died.
Teacher: Students, how do you feel after watching this cartoon? (Students speak freely) I feel sorry for the little fish, because the river is polluted and the environment is destroyed. Moderator: Partners, what are the phenomena that destroy the environment around us? What harm do they have? Ask students to discuss and answer.
(Students speak freely) I feel sorry for the little fish, because the river is polluted and the environment is destroyed.
Moderator: Partners, what are the phenomena that destroy the environment around us? What harm do they have? Ask students to discuss and answer.
(Students speak freely) Cutting down trees, randomly discharging waste water, littering, seawater pollution caused by mariculture, and quarrying on mountains destroying the ecological environment.
Teacher: The students are very good. In recent years, due to people's deforestation, the pollution of rivers and oceans has caused great harm to the ecological environment.
Multimedia display: smoke billowing from factories, mountains of garbage, cutting down trees and grasslands, and increasingly serious sandstorms.
How do you feel when you see all this?
Student exchange: express concern about destroying the environment and hate people who destroy the environment.
(Multimedia display data: Acid rain: destroying forests and corroding stone statues. Decrease of animals: The species and number of animals have decreased to an unprecedented extent. Forest destroyed: it is difficult to find virgin forest in our country now. River pollution: 90% of rivers in China are polluted to varying degrees. )
environmental protection
Moderator: Students, we only have one earth, and everyone has the responsibility to care for her beautiful face. We should take good care of her!
Teacher: Think about it. How can we protect our home with practical actions? Students speak for themselves and look for ways to protect the environment.
The group studied cooperatively with questions, discussed and expressed their opinions, and then communicated with the whole class.
Take care of every grass and tree, don't litter, take care of animals, save water, and resolutely report acts and individuals that damage the environment.
Moderator: Let's start from now on, start from the small things around us, stop damaging the environment, protect the environment and love nature. This class meeting is over.
Finally, the teacher summed up and called on the students to be small environmental guards.
Comments:
The class meeting has a clear theme and clear goals. Grasp the protection of the environment, do you want it? Start with me? Key point. In the face of the deterioration of human living environment and the destruction of the ecological balance of the earth, how to protect the environment is a common challenge faced by people on earth in the new century. Hu Jintao emphasized that the environment is the support of sustainable economic and social development and the home where we live together. Strengthening environmental protection and construction is an inevitable requirement for establishing and implementing Scientific Outlook on Development, and it is a concrete embodiment of adhering to the people-oriented principle. Incorporating this content into school moral education is obviously of great and far-reaching significance for helping minors to establish environmental awareness and develop good behavior habits of maintaining the green environment.
The class meeting pays special attention to the integration of the leading role of teachers and the main role of students in the class meeting. Through answering questions and discussing with you on the spot, students' enthusiasm and interest are fully mobilized and their subjectivity is fully exerted. To be sure, the designer is about to establish the theme. Environmental protection? This big theme, every one? Me? Lenovo; Then, in the process of organizing the class meeting, let students collect information independently and preside over the class meeting, so that every student can have environmental awareness and glow with passion in the contrast between beauty and ugliness, from the beauty of beautiful rivers and mountains to the sigh of environmental pollution; Under the guidance of the teacher, I will inspire the sense of responsibility for environmental protection and care for human life, and make it clear that environmental protection can start from my side, from caring for every grass and tree in the campus.
The highlight of the class meeting lies in the extensive use of multimedia means and various network resources, and the visual effect is obvious. However, the class meeting was a little insufficient at the end, and the theme propaganda was not enough. It fails to fully demonstrate the importance of individuals starting from small things in environmental protection, especially the ways and possibilities of starting from themselves in the protection ring are not fully explored.
The teaching plan of environmental education theme class meeting aims at:
1. Guide students to pay attention to the earth, the common living environment of human beings, and make them understand the importance of protecting the ecological environment and caring for human resources. Establish environmental awareness, improve environmental practice ability, stimulate the emotion of sharing home, and enhance the sense of environmental responsibility.
2. Understand the important role of environmental protection in the growth of animals and plants and the development of human society, understand the resources on the earth, enhance environmental awareness, and cultivate feelings of loving nature.
3. Cultivate students' ability to express, collect, accumulate, arrange and use information in language through various activities such as collecting data, observing and discussing.
Activity flow:
1. Projection shows the beautiful mountains, rivers, lakes, animals and plants on the earth.
1. Let the students introduce the lake and show the pictures.
Taihu Lake, located in the Yangtze River Delta, is the third largest freshwater lake in China with a storage capacity of 5 1.4? 10 8m 3, in addition to providing a large amount of industrial water and agricultural irrigation water for the lake, is also the drinking water source for nearly 20 million residents along the lake and Shanghai.
Chaohu Lake is located in the middle of Anhui Province, between the Yangtze River and Huaihe River, and is one of the five largest freshwater lakes in China. It used to be land, but because of the subsidence of the surface, it became a huge immersion. Luo Yin, a poet in the Tang Dynasty, wrote the poem "Notre Dame Temple of Dengchao Lake": it has been thousands of years since Qin and Han Dynasties. . The flat terrain along the lake, vertical and horizontal canals, irrigation area of 3.28 million mu, is the richest place in Anhui.
Hongze Lake provides abundant water resources for the improvement of 6,543,808 mu of farmland and coastal saline-alkali land in northern Jiangsu. Hongze Lake was formed by the migration of the Yellow River to the south of the Yangtze River. The lake is completely protected by the eastern levee, and its bottom is 4.8 meters higher than the eastern plain. Hanging lake? Once the flood breaks its banks, will it appear? Don't the flooded Gaojiayan meet in Jianghuai City? A tragic scene. After the establishment of People's Republic of China (PRC), water conservancy projects such as Sanhe Sluice, Hull Sluice, and rivers entering the river were built, making Hongze Lake a large reservoir with comprehensive utilization of flood storage, irrigation, shipping, power generation and aquatic products. Sunrise for gold? The reputation of.
Dongting Lake and Poyang Lake shoulder the heavy responsibility of regulating floods in the middle reaches of the Yangtze River. Dongting Lake and Poyang Lake Plain have always been famous food crops in China. Is the lake wide and ripe, and the world is full? They all benefit from the fertile soil and abundant water resources provided by lakes.
2. Summary: How do you feel? The earth is lovely, she is so beautiful.
Second, organize exchanges.
1, Teacher: These days, we have observed the surrounding environment. Now, who will tell you where you found the dirty things?
2. Teacher: What are the feelings of these places with garbage, and what are their effects on the environment, people and animals and plants?
3. Teacher: When Mother Earth left the 20th century with ecological burden and trauma, did we ever think about what kind of disaster the excessive consumption of resources and environmental pollution caused her? What responsibility does each of us have in such a disaster? When the fragile ecology is difficult to maintain, how will human consumption continue? When the earth is terminally ill, how long can humans live?
Humans can't survive without the earth, so what should we do with what we live on? Mom? What about the earth? What shall we do with the rubbish?
5. Teacher: We must dispose of the rubbish.
Please introduce some treatment methods to XX.
6, garbage disposal methods
(1) landfill treatment
Landfill is an effective method to absorb a large amount of municipal solid waste, and it is also the final disposal method of all the residues in the garbage treatment process. At present, the direct landfill method is widely used in China.
The so-called direct landfill method is to fill the garbage into the prepared pit, cover and compact it, make it undergo biological, physical and chemical changes, decompose organic matter, and achieve the purpose of reduction and harmlessness.
In Tianjin, the south side of the water park uses garbage dumps to create an artificial environment, turning harm into benefit. The project covers an area of nearly 800,000 square meters. Garbage and engineering waste soil are mixed according to the ratio of 1: 1 as the source of pile soil, and necessary measures are taken for leachate, biogas produced by fermentation and the stability of hillside.
However, most of the garbage in many cities in China is still piled up in the open air without any protective measures. Every garbage dump has become a source of pollution. Mosquitoes and flies are rampant, rats are infested, and the smell stinks. A large amount of garbage and sewage seeped into the ground from the surface, which caused serious pollution to the urban environment and underground water sources. In Shenyang, 10 in 35 landfills was drilled and sampled, and the fault samples of garbage and groundwater quality were analyzed. The analysis results show that the groundwater quality is deteriorating, the pollution is serious, the water quality is turbid and smelly, and anaerobic Escherichia coli is detected in the water; Toxic and harmful substances were detected in all samples of garbage failure. Every day in Shanghai, 10,000 tons of garbage are transported to the suburbs and piled up at the seaside. The garbage mountain as high as twenty or thirty meters has caused serious pollution to the surrounding environment.
(2) Incineration is a method of putting garbage into a high-temperature furnace to fully oxidize the combustible components in it, and the generated heat is used for power generation and heating. The garbage conversion energy system jointly developed by Westinghouse and O 'Connor Company has been successful. The incinerator of this system can convert garbage with humidity of 7% into dry solid for incineration, and the incineration efficiency is over 95%. At the same time, the high temperature on the surface of the incinerator can convert heat energy into steam, which can be used for heating, air conditioning equipment and steam turbine power generation.
There is an incineration station in Shijiazhuang, China, and the Shenyang Institute of Environmental Science introduced a Japanese garbage incineration device to treat the special garbage in hospitals and other units harmlessly. The residual ash produced in the incineration process accounts for about 5% of the weight of biological waste before incineration, which is generally high-quality phosphate fertilizer. In recent years, China has paid more and more attention to the technology of generating renewable energy from garbage incineration.
The advantages of incineration treatment are good reduction effect and thorough treatment.
However, according to American reports, the construction and production costs of incineration plants are extremely expensive. In most cases, the value of electricity generated by these devices is far below the expected sales, leaving huge economic losses to the local government. Because garbage contains some metals, incineration is highly toxic and will cause secondary environmental harm. Incineration requires the calorific value of garbage to be greater than 3.35MJ/kg, otherwise combustion improver must be added, which will increase the operating cost to an unbearable level for ordinary cities.
(3) Composting: stacking and storing domestic garbage, fermenting at 70℃, and decomposing organic matter into inorganic nutrients with the help of the decomposing ability of microorganisms in garbage. After composting, domestic garbage becomes sanitary and odorless humus. It can not only solve the way out of garbage, but also achieve the purpose of recycling. However, domestic waste compost has a large amount and low nutrient content, so long-term use is easy to cause soil hardening and groundwater deterioration. Therefore, the scale of compost is not easy to be too large.
Whether it is landfill, incineration or composting, pretreatment is essential.
The pretreatment procedure first requires residents to bag domestic garbage according to recyclables, organic matter and inorganic matter, and then the garbage disposal company collects and transports it according to the garbage classification, and treats it separately.
7. In order to ensure the garbage disposal, all countries have made corresponding laws.
According to the regulations of Seattle municipal government, each household needs to pay a fee of $65,438+$03.25 for transporting four barrels of garbage every month, and an additional fee of $9 is required for each additional barrel of garbage. After the implementation of this regulation, the amount of garbage in Seattle has decreased by more than 25%.
Does Italy have a tax law? Plastic bag tax law? It is expressly stipulated that each plastic bag should be taxed at 8 cents. Every time a store sells a plastic bag worth 50 lire, it has to pay a tax of 100 lire. German law stipulates that every container that cannot be recycled should be taxed at 30 finnies.
The prohibition law has been implemented in nearly half of the States in the United States since July 1989? Prohibition law? All plastic food packages that cannot be decomposed and reduced are prohibited from going on the market. German government legislation stipulates that from June 1993 1 day, sellers must recycle all used packaging and container products free of charge. Otherwise, it's illegal? Waste packaging materials act? Punishment.
The French regulation on garbage disposal is that anyone who gives up or scatters any kind of waste, waste and other garbage into a public place or private place that does not belong to him and has no beneficial right or lease right will be fined 250 yuan? Six hundred francs. Those who abandon used cars or need vehicles to carry and clean things will be fined 2500 yuan? 5000 francs or 10? 30 days in prison.
8. The World Environmental Protection Organization has also issued an appeal to the whole world and set many meaningful days.
World Water Day: 1993 The United Nations General Assembly adopted a resolution to set March 22nd as? World Water Day? Sound the alarm for the increasingly scarce water resources and the increasingly serious water pollution on the earth.
