Garbage disposal teaching plan 1 teaching content:
Oral communication: "How to deal with the garbage around us"
Teaching objectives:
1, improve students' oral expression ability and listening ability.
2. Cultivate students' imagination and creativity.
3. Cultivate students' good quality of caring for the environment.
Teaching focus:
1, improve students' oral expression ability and listening ability.
2. Cultivate students' imagination and creativity.
Teaching difficulties:
Cultivate students' good quality of caring for the environment.
Teaching preparation:
Handicrafts made by students from garbage.
Teaching process:
Design guidance of teachers' activities and students' activities in the teaching process.
First, pictures stimulate interest and introduce topics.
1, children, today the teacher brought a lot of pictures. Do you want to see them? Show me the relevant rubbish. Where do the pictures come from: for example, mom picks vegetables, peels apples, and planes pencils. ) After reading it, tell me what you saw.
2. blackboard writing topic. Look at the pictures, answer the questions and read the questions together. Contact life and actively participate in the speech situation.
Second, create a situation to stimulate interest. Today, the teacher is the host of "Tell the truth", and the children are the guests at the scene, sharing their findings: Where did the garbage come from? 1. Panel discussion
Communicate with the whole class
(1) Garbage is all useless things that people throw away from home.
(2) Garbage is thrown away by unsanitary people at will.
We think garbage should be thrown away. What's the use?
(4) Garbage is our human garbage, but some can be used and some are useless. Through students' discussion, students have a preliminary understanding of the garbage around them and have different views.
Three. Create a scene to deal with garbage. Guide students to change their angles. If you are an invited park manager, talk about how you should deal with the garbage.
1. Discuss at the same table.
2. The whole class exchange evaluation.
(1) Throw the garbage into the sea.
(2) Burning garbage to generate electricity.
(3) Making handicrafts with garbage. Discuss at the same table in the class to encourage students to reflect on the behavior of garbage disposal in life and talk about their own views.
Four. Create a scene to show your talents. Did the teacher bring the little things made by the students yesterday? Students' presentations and reports on stage, such as
(1) "My work is a flower basket. I first find a useless bottle, take a pair of scissors to cut off the top, then cut out strips of lace and circle the lace to make a beautiful flower basket.
(2) My work is a warship. I made this warship out of useless foam, toothpicks and some pieces of paper.
Through the exhibition, it not only has a place for garbage disposal, but also improves students' practical ability and promotes their oral communication ability.
Five. Expand activities. Please work in groups and draw your own ideas. Draw a "future garbage disposal site" in cooperation with the group to promote students' interaction, talk in interaction and communicate in interaction.
Postscript of teaching:
I mainly use the literacy method of "one plus one, one minus one, one middle school and one middle school" and the method of orderly expression and communication to guide students to observe and discover, read aloud, recite, say and do. Cultivate students' independent literacy, actively accumulate language interests and habits, and stimulate students' feelings of protecting the ecological environment.
"Oral communication" I mainly ask students to guide students to communicate and discuss the garbage around them, and let students talk about how to deal with the garbage around them. The students speak very well. For example, some people say that they should take the initiative to pick up garbage; Some people say not to litter; Others say to stop others from throwing garbage. I also instruct students to draw their own ideas, and further improve students' awareness of environmental protection by combining students' stick figures. The effect is very good.
Design background of garbage disposal lesson plan 2 activity
Walking in the street, I saw a child and his mother throwing garbage while eating. Next to the trash can, I immediately picked up the garbage and threw it into the trash can. I immediately thought of the children in our class and told them that this kind of behavior is wrong, so that children can understand the harm of littering! Understand how garbage is treated.
moving target
1. Let the children know some ways people deal with garbage.
2. Enhance children's awareness of environmental protection.
3. Willing to try boldly and share experiences with peers.
4. Cultivate children's keen observation ability.
5. Explore and discover the diversity and characteristics in life.
Teaching emphases and difficulties
1. Ask children to remember not to litter at all times, but to throw it into the dustbin.
2. Let the children influence the people around them and the people at home, and know the harm of garbage to people.
Activities to be prepared
1, a big basket
Every child will bring newspapers, cans, cartons, glass bottles and other waste items from home.
Activity process
1, through the dialogue, guide the children to say that garbage is unwanted or useless.
2. Tell the children that unnecessary garbage should be thrown into the dustbin. If we throw away some rubbish every day, there will be more and more rubbish on the earth, which will affect my sparkling health.
3. Let the children know that people put the garbage into the trash can and then the sanitation workers transport it to the garbage dump for treatment.
4. Guide children to classify garbage:
(1) What can be recycled? Such as plastic bags.
(2) What are the non-recyclable garbage? Taiwan Province peels, cigarette butts, etc.
(3) Hazardous waste: If batteries are used, they should be put into special trash cans to prevent environmental pollution.
5. Educate children to care for the environment at ordinary times, don't litter casually, and strive to be "little guardians of environmental protection"
Teaching reflection
After class, children can be organized to use plastic bottles for simple small-scale production, knowing that many waste items can be turned into treasure. Not only are children required to form the good habit of throwing garbage into the dustbin, but each of us should do the same. Only in this way can our life and every place be kept clean and tidy.
Garbage Disposal Teaching Plan 3 Activity Objectives:
1, understand the process of different garbage disposal, understand the relationship between garbage disposal and the environment, and know that improper garbage disposal will bring harm to the environment.
2. Experience the fun of sharing in the process of exchanging the collected garbage life information.
Activity preparation: pictures and newspaper clippings collected by children about garbage life; Pictures and CDs about garbage disposal.
Activity flow:
1, organize a dialogue.
1) Let the children tell their knowledge and information about garbage life in front of the group.
2) Teacher's summary: cigarette butts 1-5 years, cigarette filters1-0/2 years, waterproof paper for 5 years, paper for 2-5 months, leather and tin cans for more than 50 years, nylon cloth for 30-40 years and woolen socks 1-5 years.
2. Understand the garbage disposal process.
1) Question: Garbage can survive around us for such a long time, which has brought great harm to our lives. How to deal with the garbage?
2) Watch the video of "garbage sorting and recycling" to guide children to understand the situation of garbage recycling and feel the convenience brought by technology.
3) Show a picture summary: garbage will be decomposed by burying and burning. Some of the garbage is easily decomposed, such as food and some natural garbage (such as fallen leaves), which will rot after being buried for a period of time; But some garbage is difficult to decompose,
Things made of plastic and glass need to be buried for a long time. Nowadays, people classify, treat and recycle garbage and turn it into useful things. For example, vegetable skins, peels and meat bones can be made into good agricultural fertilizers; Paper and cartons can be made into raw materials for papermaking. Old plastics and broken glass can make new plastics and new glass.
3. Organize a discussion: How do children want to treat and use these wastes?
Garbage disposal teaching plan 4 teaching objectives:
1, recognize the new word 10 and recognize 9 words. Can write about six structured words.
2. Use various methods to understand the meaning of new words.
3. Read the text for the first time to understand the environmental protection knowledge introduced in the text.
Teaching focus:
Recognize 10 new words and 9 words. Can write about six structured words.
Teaching difficulties:
I can write about six words in one structure, and the word "environment" is the difficulty.
Teaching process:
First, the introduction of passion
1, Teacher: The teacher brought you a friend. Do you know that?/You know what? (He said, showing a photo of an earthworm) Yes, this is an earthworm, a bug. So the word earthworm is next to the word worm. (saying and pasting the word earthworm) Read this word. There's another word,
2. (show garbage) reading. What rubbish is there in life? How unsanitary it is to throw rubbish like this! Earthworms can remove these domestic wastes.
The text we are learning today is about garbage disposal. The topic is "Earthworm Manure Treatment Plant". The teacher put the word "plant" after "treatment". Teacher: Tell me what kind of plant it is with your reading aloud. What kind of treatment plant is this? What kind of garbage disposal plant is this? )
4. Do you have any questions after reading the project? Presupposition: Students may ask: How do earthworms deal with garbage? What is the relationship between earthworms and garbage disposal plants? Why build an earthworm dung treatment plant? The teacher evaluates the ways to guide students to ask questions, such as the reason why you ask things. Comments, simple records. )
5. Transition: The question you asked is really good. I believe you can solve these problems if you study hard.
Second, independent inquiry.
1, please read the text by yourself. Read it several times when you encounter new words, words you know and words you are not allowed to read. Try to read the pronunciation correctly and understand the sentences. Read the new words to your partner after reading them.
2. Teacher: Check the reading words and read difficult sentences.
A, show the words, read them together, (guide to understand the meaning of convening, pollution, environment and suggestions, and solve the polyphonic words: part one) read them separately. Hold (meeting) Pollution (environment) (The teacher said while projecting words: Have you all seen it? Then I will test you. Look at the new words. The baby is coming out. What is this (call)? Every Tuesday, teachers have a meeting. This is (pollution). What pollution? (Environment), if you litter casually, it is (polluting the environment). Show me the picture: this is a polluted river. Show the pictures and talk about the environment of our school.
B. Suggest earthworm garbage (read by name) (teacher; Look, there is another sentence here. You practice reading it. Who will read it? ) Show: Earthworms whispered, "I suggest to build an earthworm garbage treatment plant ..." Understanding suggestion: The teacher also has a suggestion for you, suggesting that you have a good class. Who wants to give a suggestion to the students?
C, burn the Olympic Games that buried the discussion partner's neighborhood committee.
3. Infiltrate part of speech: show the first group of words and read them by name. What are these words? Show the second group of words and read them by name. What do these words mean?
There is a polyphonic word here. who is it? He also read lún, the word lún is only read in The Analects of Confucius, and Lú n is read at other times. Discuss, discuss, talk about what should be done? So these words are beside the words. (division; This is another sentence with many punctuation marks. Who will read it? I heard that one year, the waste paper, vegetable leaves, peels and other domestic garbage of the Olympic Games were all treated with earthworms. (Evaluation leads to reading pause) Here is another sentence with many new words. See if you can read well. After repeated discussions, the Animal Neighborhood Committee decided to adopt earthworm's suggestion and build an earthworm garbage treatment plant.
5. Transition: You read these words very well. The teacher separated out the new words. Do you still know them? Taken alone, these words are second-class words. You can recognize second-class words so well. I believe you can better recognize the first-class words. Show the projection, read the first word, and jump off the train. Can you classify these nine words by structure? (Let the students say how to divide it) The teacher projects the left and right structures: Discuss the environment and discuss the upper and lower structures: Call for semi-closed Olympiad: In this lesson, let's learn to write these words with the left and right structures. How to remember these words? Can you combine these words or say something with them? Please discuss and study in groups.
6. Group presentation. A group reports the words next to the words, a group reports the words next to them, and a group reports the rest.
7. Guiding writing: What are the characteristics of these words with left and right structures? (If you use courseware to assist observation, you must use regular script) Look at the height of the two parts again and keep it in mind. Which two words do you find difficult to write? The teacher wrote another word "environment". The teacher believes that you can write beautifully yourself. But before writing, I want to remind you to pay attention to the order of words. After writing, write a little first, then write.
8. We write down these words with left and right structures in the book. You can make suggestions to each other in the group after writing. Remind students to write. ) find one or two problematic word projections and comment together. Which word you think is not good-looking, correct it and write one for each word.
Third, put the words in the text before reading it.
Transition: You are really good at learning new words. I believe you can read the text fluently now! Let six students read the text, each with a section. Other students listen carefully and want to know what problem you have solved. What other problems remain unsolved?
1, read by name, one section per person.
2. Name the books you have read? After the students say it, who can combine the meanings of several of their classmates and say it?
3. Are there any questions you don't understand? Say these questions, and we will discuss them together next class.
Summary:
What did you learn from this course?
Teaching objectives of garbage disposal teaching plan 5
Knowledge and skills: at present, the main methods of garbage disposal are landfill and incineration, and simple landfill and incineration will cause environmental pollution; Reasonable landfill design can effectively reduce environmental pollution.
Process and method: Through the simulation experiment of landfill, the hazards of simple landfill were observed and analyzed, so as to consider and try to design a reasonable landfill and understand the facilities and functions of modern new landfill.
Emotion, attitude and values: guide students to pay more attention to and think about the garbage problem and improve their awareness of environmental protection.
Teaching focus
1, do the simulation experiment of simple landfill, observe and analyze the harm of simple landfill, and explore and try to design a reasonable landfill.
2. Understand the facilities and functions of the new landfill in detail, and realize that advanced garbage disposal methods still have an impact on the environment.
Teaching difficulties
Understand the facilities and functions of the new landfill and realize that advanced garbage disposal methods still have an impact on the environment.
Equipment preparation
1, group experimental materials: glass bottles, washed pebbles, ink, paper towels, plastic bottles (there are some holes in the bottle cap).
2. Structural diagram of modern new landfill.
3. Videos, pictures, texts and other materials of garbage disposal process in landfills and incinerators.
Teaching design
First, import
Talk: From the last lesson, we know that a lot of garbage will be produced every day. How to deal with this rubbish? Let's look at the pictures together.
Show some photos of garbage piled up in the open air, and guide the students to discuss: What harm will garbage in life do if it is piled up in the open air?
Discuss and report in groups. (such as: destroying the environment, polluting air and water, causing diseases and fires, etc. )
The teacher explained: People usually dig holes and bury garbage. Now cities have established large-scale landfills. At present, more than 80% of the country's garbage is treated by landfill. A map showing a large landfill. Today we will study this problem together. The blackboard says: garbage disposal
Second, the study of simple landfill
Teacher's Notes: We study simple landfill through experiments.
2. Guide students to read the content on page 72 of the textbook: put the washed fine stones into a jar about 3 cm thick, and then add clear water to make the water just half of the stones. Use tweezers to put several groups of paper towels soaked in ink near the bottle wall, bury them with fine stones, and then slowly spray water on them.
3. Simulation experiment analysis of landfill;
(1) What does this experiment simulate? (Landfill)
(2) What do the various parts of the experiment represent? Pebbles represent soil, clear water under pebbles represents groundwater, paper towels stained with ink represent garbage, ink on paper towels represents sewage in garbage, and water spilled from them represents rain. ) Discuss in groups and report the opinions of each group.
Students should experiment in groups according to the steps in the book.
Thinking: What phenomenon have you observed? What does this mean? Group cooperation experiment, teacher patrol guidance.
Student report.
5. Discussion: If it is a real landfill, what harm will it bring to the surrounding environment?
Report after group discussion. (garbage will produce a lot of bad smell and breed pests such as flies and cockroaches; Garbage is soft and easy to collapse. )
Teacher's camera introduction: simply bury the garbage, and the sewage in the garbage will spread. Sewage diffuses into the surrounding soil. If vegetables and grain are planted in the polluted soil, would you like to buy them and eat them? What is even more frightening is that with the spread of sewage in garbage, groundwater will be polluted. Moreover, groundwater will flow everywhere, so bacteria and toxins in sewage will spread to a wider range with groundwater, endangering people's health. In addition, if the garbage dump lasts too long, methane will be produced and an explosion will occur.
Third, explore landfill sites to reduce pollution.
1, put forward the task: how to solve the harm of landfill to the surrounding environment? Can we design a better landfill?
Tip: First consider what problem to solve (mainly groundwater pollution), and then try to solve the problem (isolate garbage from the environment).
2. Try to design in groups and record the design points.
3. Report and exchange the designs of each group for your evaluation.
4. Observe the structural diagram of the real landfill and analyze how it prevents the garbage from polluting the environment. (First observe the schematic diagram on page 73 of the book, and then show the Tianziling landfill site in Hangzhou through multimedia. Its technology is very advanced, and it is one of the top ten landfills in China, where 70% of the garbage in Hangzhou is buried. Then, the anti-seepage technology, biogas power plant and sewage treatment of Tianziling landfill site are introduced. )
5. Thinking: Will this landfill be safe forever? Can you grow crops and build houses on it?
Teacher: After landfill, parks and stadiums can be built on it, but they can't be used to build houses and grow crops.
Fourth, the analysis of garbage incineration
1. Teacher's introduction: Incineration is another way of garbage disposal, that is, burning garbage in an incinerator.
2. Discussion: What are the advantages and problems of burning garbage? The teacher explained that the construction of waste incineration facilities needs more capital investment, and Hangzhou Green Energy Environmental Protection Power Generation Co., Ltd. showed it through multimedia. Its investment is nearly 200 million yuan, and its technology is leading the country and very advanced. Students discuss and express their group's views.
Teacher's summary:
Advantages: small floor space, preventing garbage from polluting groundwater, and generating heat to generate electricity. Disadvantages: it will consume a lot of electricity and leave residue. If it is not well controlled, it will also produce toxic substances and cause secondary pollution.
Extension and improvement of verb (abbreviation of verb)
Thinking: What is the more effective way to solve the garbage problem?
Sixth, the class summary
Sort out the current garbage disposal methods and their advantages and disadvantages, and record the effective methods to solve the garbage problem.
Question: What did you learn from this lesson? How do you feel?
Garbage Disposal Teaching Plan 6 Activity Purpose
1. Cultivate students' awareness of environmental protection and sustainable development through the study of this course.
2. Let students know that recycling garbage and turning waste into treasure have a positive effect on our life and social development; Cultivate the awareness of garbage recycling and teach yourself garbage classification.
3. Through experiments, let students know the methods of garbage disposal and design more disposal methods independently.
4. Through activities, cultivate students' ability of observing, imagining, classifying and solving practical problems, and stimulate students' interest in innovation and exploration.
Activities to be prepared
Video, chewing gum
I-word duration
1 class hour
Activity process
First, take a look.
Watch the video: Visit the waste paper processing factory to understand the significance of recycling a ton of waste paper into paper: processing a ton of waste paper into recycled paper can save 100 tons of water, reduce water pollution by 35%, cut down 17 trees less and make 800 kilograms of recycled paper.
Second, check it
Guide students to go out of school, conduct social surveys, go to the library to find information and understand the basic ways of garbage disposal.
Third, let's talk about it: study the treatment method of garbage:
1, Question: So how to deal with this garbage?
2, group discussion, and design the garbage disposal scheme, written down by the team leader.
3. Class communication: By comparison, which group's scheme is the most scientific and reasonable?
4. Go online to learn about the disposal methods of garbage in the world.
▲ Garbage classification. Garbage mixed loading is to treat garbage as waste, and garbage sub-packaging is to treat garbage as resources; The mixed garbage is sent to landfill, occupying a lot of land, and the sub-packaged garbage is distributed to various recycling departments without occupying land; Mixed garbage, whether buried or burned, will pollute the land and atmosphere, and repackaging garbage will promote harmless treatment; Mixed garbage increases the work of sanitation and environmental protection departments, and repackaging garbage only requires our little efforts.
▲ Garbage collection. In domestic garbage, recovering aluminum from aluminum cans consumes 7 1% less energy than extracting aluminum from bauxite, and reduces air pollution by 95%. Recovering glass from waste glass can not only save quartz sand, soda ash, feldspar powder and coal, but also save electricity, reduce energy consumption by about 32%, reduce air pollution by 20% and water pollution by 50%. The energy saved by recycling a glass bottle can keep the light bulb on for 4 hours. Recycling 1 ton waste paper can produce 800 kilograms of good paper, cut down less 17 trees, save 3 cubic meters of landfill space, save more than half of papermaking energy, reduce 35% of water pollution, and each paper can be recycled at least twice. Office paper, old envelope stationery, notebooks, books, newspapers, advertising paper, loan wrapping paper, cartons, paper tableware, etc. It can be recycled for the first time and printed into books, manuscripts, business cards, notes and so on. After the second recycling, it can also be made into toilet paper.
▲ Turn garbage into treasure (compost, power generation, etc.). ). The State Environmental Protection Administration of China has announced to the public an action plan to deal with municipal waste. According to this plan, China's urban garbage will be landfilled in the future, and the gas generated from landfill will be collected to generate electricity.
▲ Landfill.
▲ Garbage incineration.
Fourth, do it.
Do an experiment in dealing with chewing gum garbage in class, and publicize the correct garbage disposal method in school and community after class.
Garbage Disposal Teaching Plan 7 Garbage Classification Children's Songs: Let's protect the environment together. Garbage classification is the most important, recyclable, harmful waste blue, red, kitchen waste green, other garbage gray. Remember the classification book. I will start with garbage sorting and take it out scientifically and orderly. Garbage classification should be adhered to. Creating civilization depends on everyone. Garbage sorting is no longer difficult. Everyone in the happy world.
The state advocates garbage sorting, and children should also know something about domestic garbage. Brother Xiaoyu also designed a garbage course and conducted it in his own kindergarten.
The purpose of the course plan:
1, let children know what domestic garbage is, how to produce it and what harm it has.
2. Let children know the importance of cleaning up garbage and the hard work of garbage cleaners.
3, let children develop a good habit of not littering, and develop a good habit of throwing garbage into the trash can.
Focus of activities:
What are the hazards of domestic garbage? This is difficult to talk about, and it is also a place that children don't quite understand. It is suggested that teachers can find a breakthrough from the children themselves, especially the experiences they have had. For example, slip by banana peel, cut by broken glass and so on.
Activity difficulty:
The difficulty of the activity lies in getting children to develop the habit of not littering, which takes a long time to operate. It doesn't mean that you can let your child develop this habit by giving him such a lesson.
Course plan preparation:
Download some photos of garbage in advance, including photos of workers handling garbage, as well as photos of pollution and harm to the environment caused by garbage incineration, as complete as possible, and then find some photos of garbage closely related to children's lives.
Teaching plan process:
1, the teacher plays photos to the children one by one through the projector. In the process of playing, teachers can also interact with children. What do you see in the photo? Do you think this is right?
2. After watching the pictures, discuss with the children how these domestic wastes are produced.
3. The teacher told the children a summary about the generation process of domestic garbage, especially the domestic garbage that children often produce in their lives.
4. The child speaks freely, and then talks about the domestic garbage he realizes and the causes.
Activity expansion:
Take children to clean indoor and outdoor sanitation. Teachers and children clean up the garbage together and put it in the trash can seriously.
Activity summary:
Son, there is so much garbage in our kindergarten, there will definitely be more unnecessary garbage at home, won't there? So what do you do when you see garbage at home? Yes, throw it in the trash can. The children are great. Also, if children have rubbish outside, should they just throw it into the street? Yes, the children answered wonderfully. So, what kind of good children are we going to be? Yes, we should be good babies who don't litter.
