"Pollution" lesson plan 1 activity goal
1, through experiments, let children know that plastic bags are white garbage that will not decompose.
2. Teach children to put things in paper bags or cloth bags.
Activities to be prepared
1, Ppt courseware: white pollution
2. A plastic bag.
3. Two potted flowers cultivated according to the activity.
Activity process
First, let children know that plastic bags will pollute the soil.
1, discussion
We take care of these two pots of flowers equally. Why did one of them die?
2. Show two potted flowers for observation and comparison.
The teacher emptied the soil from the dead flowerpot for the children to observe.
(Children express their opinions after observation)
Summary: The poured water was blocked by plastic bags and could not seep out of the basin. The soil is often wet, which makes the roots of flowers rot. Moreover, plastic bags will pollute the soil and destroy the nutrition of the soil. Flowers die if they can't absorb good nutrition.
Second, courseware demonstration: white pollution
Children watch the courseware and guide them to discover the environmental pollution caused by plastic bags.
Discussion: What kind of pollution will plastic bags cause to the environment?
Summary: littered plastic bags blocked ditches and rivers, leading to flooding; Animals ate plastic bags and died; The soil was polluted by plastic bags, and all the plants died.
Third, children participate in small experiments to further understand that plastic bags will not decompose by themselves.
1, the teacher put forward experimental questions, which aroused the children's interest.
What happens if we put plastic bags and paper in water and turn it over?
2, the child's discussion, guess the result according to the child's own experience.
The children observed the experiment and found that the paper was quickly shredded, while the plastic bag remained unchanged.
Fourth, teachers and students * * * with the summary, plastic bags are not easy to decompose.
1. How to prevent plastic bags from polluting the environment?
In life, we should use less plastic bags, and the used plastic bags should not be littered and put in the trash can.
2. Use cloth bags or paper bags.
5. I am a small environmental protection guard.
Let children freely discuss what to do as a small environmental guardian.
Top-quality course of science in large class: animal self-defense stunt
"Pollution" lesson plan 2 Activity objective:
1. Further feel the serious pollution caused by plastic products to the environment, and initially understand the current scientific methods to solve this pollution.
2. Enhance environmental awareness.
3. Cultivate children's keen observation ability.
4. Initially cultivate children's ability to solve problems with existing life experience.
5. Explore and discover the diversity and characteristics in life.
Activity preparation:
1. Ask experts to make relevant introduction.
2. VCD movies about solving plastic bag pollution.
Activity flow:
First of all, further understand the use of plastic bags in life.
1. Please collect the plastic bags brought by children and feel the number of plastic bags.
2. So many people in our whole residential area, Hangzhou, Zhejiang, the whole country and the whole world are constantly using plastic bags. What will happen?
Second, try to express your concern about plastic bag pollution through painting. (For example, there are mountains of plastic bags, the scene that the earth is "submerged" by discarded plastic bags, the phenomenon that plastic bags pollute the environment and so on. )
Third, discuss ways to reduce the pollution of plastic bags.
1. Plastic bags are so polluted, is there any solution?
2. When the child proposes to replace plastic bags with baskets, paper bags and cloth bags, please tell him what are the advantages of using these bags and why. Baskets are durable and washable; Paper bags are easy to carry, pollution-free and recyclable; The cloth bag can be cleaned and reused. )
At present, we can't ban the use of plastic bags. What should we do with these non-perishable plastic bags?
4. Teacher's summary: At present, the environmental protection department mainly adopts two treatment methods. One is to bury plastic bags in the soil, but it will slowly decompose into a toxic substance, which will destroy the soil and plant growth; The other is burning plastic bags, but at the same time it will produce toxic gases, pollute the air and endanger human health. Neither method is ideal.
Fourth, ask questions from experts.
1. Please ask the children to ask the experts for advice on plastic bag pollution and its treatment.
2. Ask experts to introduce the current scientific methods to solve the pollution of plastic bags: substitution method and recycling method.
The teacher concluded that plastic bags will bring serious pollution, so we should advocate replacing plastic bags with cloth bags and paper bags. Another way is to send waste plastic bags to the factory for refining. Some waste plastic bags can be processed to produce paint and new plastic raw materials, but this work is difficult to carry out.
Activity reflection:
The classroom effect of this class is good, basically achieving the predetermined goal. The child has a strong interest and cooperates with me very tacitly. Children have a basic understanding of the harm of plastic bags and set up a preliminary awareness of environmental protection.

Scientific field:
Provide cotton, test tubes, cigarettes and other experimental supplies. Each group has a big basin, straws, wool, transparent glue, plastic bags, clay plastic cups, glasses, matches and candles. (Operate under the guidance of the teacher to ensure the safety of the experiment) Operating area: no-smoking signs, pictures, paper and watercolor pens. Several performance areas: collect some songs praising hometown and put them in the performance area. Animal headdresses are used for children's performances.
Wall creation:
1, environmental education articles, environmental protection signs designed by teachers, pictures of industrial waste gas pollution, environmental protection signs designed by children.
2. Use the window and post slogans to publicize environmental protection knowledge to parents, and publicize the significance and content of environmental protection festivals such as World Environment Day, Arbor Day, Bird-loving Week, Earth Day, No Tobacco Day and Ozone Day.
Childcare work:
1, collect video and pictures of waste gas pollution.
2. Organize children and parents to actively participate in the "green action" organized by all sectors of society to protect the environment.
3. Hold lectures on environmental protection.
4. It is suggested that the grade group issue a Letter to Parents, clearly stating the significance of the theme, the content of the activity, the work that needs parents' cooperation and related precautions (the specific requirements of the activity).
Activity reflection:
Let students know that animals are good friends of human beings through the lesson "I make friends with animals", let students fully feel the cuteness of animals, inspire students to like animals and be willing to make friends with animals, and make it clear that they should have love and responsibility in getting along with animals in activities.
First of all, according to the cognitive characteristics of senior two students, I organically integrated the content of the course and determined that the focus of the textbook should start with the small animals around the students. Through close contact with small animals, students have made it clear that if they want to be true friends with animals, they must have love and responsibility, and put the education of "love" through the whole teaching process. Secondly, students are always the main body of learning activities. In teaching, through the close contact between each group and small animals, every student can participate in the activities, feel and experience in the interaction with animals, and every child has a further understanding and improvement of animals in the activities.
Pay attention to the cultivation of students' emotions in class. By letting students observe the fish swimming in the fish tank and the food they eat, they can learn about fish in the activity, cultivate students' feelings of being close to animals, loving animals and sharing happiness with animals, and initially experience the relationship between people and animals, so that students can experience, perceive and comprehend in the activity and improve themselves. Morality and Life advocates "returning to life". Before the end of the new course, I asked students to raise small animals, scattered students can raise chickens and ducks in their own yards, and students living in buildings can raise small goldfish and turtles at home. Let children know more about how to make friends with animals in the process of raising small animals, and extend classroom teaching to students' daily study and life.
"Pollution" lesson plan 4 Activity objective:
1, let children know the pollution and harm of discarded plastic bags and foam appliances to the environment and enhance their awareness of environmental protection.
2. Cultivate children's interest in scientific activities and develop their imagination and creativity.
3. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
4. Willing to try boldly and share experiences with peers.
5. During the activity, let the children experience the joy of success.
Activity preparation:
Let parents cooperate and lead their children to markets, shopping malls, fast food restaurants and other places to observe the use of plastic bags and disposable foam appliances.
Organize children to bury plastic bags, peels, leaves, disposable foam utensils, waste paper, etc. In the soil, dig them out after a period of time and observe and compare their changes.
Knowledge and experience about garbage sorting, recycling and reuse.
Physical objects, experimental data, word cards and pictures.
Activity flow:
1, display plastic bags, disposable foam appliances, and organize children to talk:
Where are these plastic bags and disposable foam appliances used the most?
How do you feel about using plastic bags and disposable foam?
◎ Teacher's brief summary: These things are most used in markets, shopping malls, fast food restaurants and other places, and they are light and easy to use. But, use these things, okay?
2. Understand the characteristics of plastic bags and foam items that are difficult to decompose, and understand white pollution.
Please listen to the story "Uncle Zhang's troubles".
◎ Guide children to follow Uncle Zhang's method (classifying word cards by garbage names): recyclable and decomposable, and finally leave plastic bags and foam supplies.
◎ Discussion: Why is Uncle Zhang worried about plastic bags and foam products? Guide children to recall the experiment of burying garbage such as plastic bags in the ground, knowing that plastic bags and foam products are difficult to decompose when buried in the ground. Ignite waste paper, plastic bags and foam products respectively to guide children to observe their combustion, knowing that the combustion of plastic bags and foam products will produce toxic gases, pollute the air and endanger human health.
◎ Summary: Waste paper, cans and other rubbish can be recycled and turned into useful things; Rubbish such as peels and leaves can be decomposed into fertilizers under the action of sunlight, rain, air and microorganisms. But plastic bags and foam products that are widely used now are not easy to decompose. Burying them in the soil will also release toxic substances, pollute the environment, occupy land, and make human land less and less. The pollution and harm caused by plastic bags, foam appliances and other environments, which we call white pollution, have brought a lot of trouble to mankind.
3. Find ways to reduce white pollution.
◎ Let children observe the pictures and talk about whether the behavior of people in the pictures helps to reduce white pollution. Why?
◎ Let children judge whether several behaviors in people's daily life help to reduce white pollution?
Let children discuss how to reduce white pollution in daily life.
◎ Guide children to express their thoughts.
◎ Guide children to start from childhood, pay attention to environmental protection, use foam appliances and plastic bags as little as possible, and tell people around them. Encourage children to love learning since childhood and create lightweight and convenient environmental protection products when they grow up.
Case observation:
Last Monday, I assigned a small task to do an experiment with my parents: bury plastic bags, peels, leaves, disposable foam utensils and waste paper in the soil and dig them out next Monday to observe and compare their changes. On the second day after the assignment, Chen Jialong, who was not very active at ordinary times, came up to me happily in the morning and said loudly, "Teacher Xia, I did an experiment with my father yesterday." I touched his head, nodded approvingly and praised him.
Next Monday, I came to the classroom for the first time. Chen Jialong came and excitedly ran over to tell me the result: plastic bags and disposable foam utensils were still the same, and the peels, leaves and waste paper were rotten.
It can be seen from here that as long as children are educated at home, they will make great progress. For example, Jialong doesn't like studying at ordinary times, and his attention is easily distracted in class. This time, due to the participation of parents, the children's enthusiasm and learning motivation have been enhanced at once.
Activity reflection:
This activity is mainly to let children know the pollution and harm of discarded plastic bags and foam appliances to the environment and enhance their awareness of environmental protection. Before this activity, we made a lot of preparations. First, parents and children were invited to do experiments at home: burying plastic bags, peels, leaves, disposable foam utensils, waste paper and so on. In the soil, dig them out after a while and observe and compare their changes. And explain some rubbish to the children.
The children's knowledge and experience were developed in the activity, and the discussion process was quite enthusiastic and the methods were different. In the end, the children were still not satisfied, so I had to say that we should continue our discussion next time.
"Pollution" lesson plan 5 activity goal
1. Know that polluted water will do harm to people, animals and plants.
2. Try to carry out publicity activities on "protecting water resources" by combining words and paintings.
Know the importance of water and share your experience with your peers.
5. Preliminary understanding of water resources protection.
Activities to be prepared
1. Parents are requested to take their children to observe the water quality of rivers and ponds near their residence.
2. Story tapes, story courseware and some pictures about the causes of water pollution.
3. All kinds of homework paper, oil pastels, pencils, markers, etc.
Activity process
First, the design suspense
1. Children listen to music stories while watching pictures.
2. The teacher asked: What happened to the tortoise? What happened to the small fish and shrimp in the river? Why did you jump out of the water?
3. Let the children find out the reason and lead to the story of "jumping".
Second, look at the courseware and let the children listen to the story with questions to find the answer.
1. After listening to the first story, the teacher asked the children, "What happened to the small fish and shrimp in the river? Why did you jump out of the water? " Children's discussion.
The teacher summed up: there are many dirty things on the surface of the pond, and the water in the pond turns black. Small fish and shrimp will suffocate if they live in it again.
2. After listening to the second story, organize children to discuss and evaluate: Dudu Bear, how did they do it? Did you do the right thing? Why?
Third, guide children to discuss how we should protect water resources.
1, show pictures to explain and analyze the main causes of water pollution:
Some people like to throw dirty things into the water, treat the river as a big dustbin and pour all kinds of garbage into the river. Sewage flows into the river, turning the water in the river black.
Most people throw garbage into the water because they have not formed good habits since childhood. What can we do to make them love the water?
"We can reason with them and let everyone protect the environment."
Fourth, discuss what to draw on the poster and how to draw water well.
1, children tell pictures
A, "I want to draw a fish, but I can't do it without water. I want to use wavy lines to represent this river. "
I want to paint and wash clothes. Without water, we can only wear dirty clothes every day. Is it also expressed by waves?
What if you draw a duckling swimming in a pond?
Can't the water in the pond be drawn in another way?
(Circle) Can you show it to everyone?
2. The teacher demonstrated the drawing method
Let me draw a beautiful water drop. Do you know which friends need water drops?
Cactus needs water drops, and it seldom rains in the desert. Cactus leaves are as small as needles, and water is not easy to evaporate, so cactus doesn't need too much water, just water drops.
Yes, there are many ways to fetch water. As long as you use your head, you can draw the propaganda of water very well.
3. Children create posters
Remind children of the transparency of water and apply it with different strength.
5. For posters with advertising words.
Children appreciate each other's works, and the teacher instructs them to match advertising words for posters.
Everyone wants a wonderful advertising word, and the teacher will print it out for you later.
For example, "water is the source of life", "water is as precious as pearls" and "water is limited".
The Design Background of "Pollution" Teaching Plan 6 in Big Class
With the continuous progress and development of science and technology, colorful plastic products can be seen everywhere in people's lives, and the wide application of plastic products has endangered our human life. I designed an educational activity of "terrible white pollution". Through pictures, courseware and objects, children can more clearly understand the serious harm of white garbage and white pollution. Enhance children's awareness of environmental protection and get a preliminary understanding of the current scientific methods to solve this pollution.
moving target
1, to guide children to understand the pollution and harm of waste plastic bags and foam products to the environment, and to enhance environmental awareness.
2. Understand the current scientific methods to solve this pollution.
3. Explore and discover the diversity and characteristics in life.
4. Cultivate children's keen observation ability.
5. Willing to try boldly and share experiences with peers.
Important and difficult
1. Teach children the importance of environmental protection.
2. Find a scientific and effective solution to white pollution.
Activities to be prepared
1, white pollutants in kind, white pollution slides, white pollution reuse video.
2, plastic bags, glue, all kinds of pictures, wool.
Activity process
First, display items, guide children to discuss and arouse children's interest.
Teacher: What do you think the teacher brought, children? Children: (plastic bags, lunch boxes, cake plates, disposable cups, yogurt bottles, biscuit wrapping paper)
Teacher: Do you know what they can do? Child: (Plastic bags can hold things, lunch boxes can hold meals ...)
Teacher: It turns out that they can do so many things, and they bring a lot of convenience to our lives. What will you do with these things after they are used up? Young (guide the children to say it and throw it in the dustbin. )
Second, put a slide to discuss the harm of plastic products to human beings.
I took some photos around us. Let's have a look. What happened?
There are pictures of waste plastic products everywhere.
Teacher: What do you see? Yang: (garbage, plastic bags)
Teacher: Why? Young people: (because people litter)
Teacher: Do you have such behavior in your daily life? Yang: (throwing the replaced snack products everywhere)
Teacher: What will happen if we live in such an environment? Young people: (sick)
Teacher: Do you know where plastic products are used the most? Young: (supermarkets, fruit shops, etc. )
② There are no rotten plastic products in the soil.
Teacher: Look, what are these people doing? Why would they do that?
Teacher: In order to promote the rapid growth of crops, many farmers will cover them with plastic film when sowing in early spring. Under the protection of plastic film, seeds can germinate and grow rapidly at a certain humidity and temperature. But what will happen after these plastic films are used up? (No rot affects the growth of crops made of plastic products)
It turns out that waste plastic films can also cause pollution. After the children return to their hometown, they will tell their uncles, aunts and grandparents about the hazards and remind them to clean up in time after using the plastic film.
③ Plastic products pollute rivers:
Teacher's Guide: What do you see in the picture?
Teacher's Guide: How do you feel when you see waste plastic substitutes everywhere in the river?
Teacher's guidance: What will happen? The fish died and the water turned black.
Teacher: Ah! It's terrible. It turns out that pollution is so harmful. We know that plastic products and foams are strong and do not rot easily. If people throw it around after use, it will form a kind of white pollution, pollute the social environment and affect people's health. Serious pollution may even endanger people's lives. Because most of these things are white, they are described as "white pollution". It is called "white pollution". Do you remember, children?
Thirdly, discuss the reuse of waste plastic products.
Teacher: transfer children's thinking and find out what else littering can also cause white pollution. Besides the white pollution brought by the teacher today, what else?
Teacher: Plastic bags are so polluted. Is there any way to solve it? (Do not use plastic products, reduce the use, etc. )
Teacher's summary: Plastic products bring serious pollution, so substitution method and recycling method can be used. So we should advocate the use of cloth bags and paper bags instead of plastic bags. Another way is to send waste plastic bags to the factory for refining. Some waste plastic bags can be processed to produce paint and new plastic raw materials, but this work is difficult to carry out.
Teacher: Let's see how they are recycled.
Fourth, summary.
Today, when children understand the harm of "white pollution", they should start from ourselves. When they go shopping, they can take bags from home and use environmental protection bags to reduce pollution, and always remind their parents and people around us that we should protect our environment together, ok?
We children can also make toys out of waste information kits. Please feel free to make: plastic vest, plastic hot air balloon.
Teaching reflection
White pollution is a broad concept. Although there is a short film before class, the harm of discipline to it is only superficial, not very specific.
Environmental education cannot just shout slogans. Only through such teaching activities can children participate and experience in person, so that children can truly feel that those living things are warning us. It not only makes children feel that there is environmental protection everywhere in life, but also stimulates students' enthusiasm for environmental protection. At the same time, environmental education is really implemented, and environmental awareness is deeply imprinted in their hearts.
