"Pollution" big class teaching plan

As a people's teacher who teaches and puzzles others, it may be necessary to compile teaching plans, which will help us to understand the contents of teaching materials and then choose scientific and appropriate teaching methods. Then the question is coming, how to write the lesson plan? The following is the lesson plan of "Pollution" compiled by me for everyone, for reference only. Let's have a look. "Pollution" lesson plan 1

Activity goal

1. Through experiments, let children know that plastic bags are white garbage that will not rot and decompose.

2. Teach children to pack things in paper or cloth bags.

activity preparation

1. Ppt courseware: white pollution

2. Plastic bags for everyone

3. Two potted flowers cultivated according to the activity content

Activity process

1. 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 pots of flowers for observation and comparison

The teacher pours out the soil in the flowerpot of dead flowers for the children to observe

(After the children observe, they express their opinions)

Summary: The poured water is stopped by the plastic bag, and it can't seep out of the pot. The soil is often wet, which makes the roots of flowers rot. Moreover, plastic bags also pollute the soil and destroy the nutrition of the soil. Flowers can't absorb good nutrition and die.

Second, courseware demonstration: white pollution

Children watch the courseware to 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, resulting in floods; Animals ate plastic bags and died; The soil was polluted by plastic bags and the plants died.

Third, children participate in small experiments to further understand that plastic bags will not decompose by themselves.

1. Teachers ask experimental questions to arouse children's interest.

what will happen if we put the plastic bag and paper into the water to spin?

2. Children discuss and guess the result according to their own experience.

3. Children observed the experiment and found that the paper quickly became shredded, but the plastic bag remained unchanged.

fourth, teachers and students * * * the same conclusion, plastic bags are not easy to decompose.

1. How to prevent plastic bags from polluting the environment?

In our daily life, we should use less plastic bags, and the used plastic bags should not be littered and put in the dustbin.

2. Use cloth bags or paper bags.

5. I am a little environmental guardian

Let children discuss freely what is a little environmental guardian.

High-quality class of science in large classes: the unique skill of animal self-defense. Pollution 2

Activity objective:

1. Further feel the serious pollution caused by plastic products to the environment, and initially understand the current scientific solutions to 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 an expert to make a relevant introduction.

2. VCD film for solving plastic bag pollution.

Activity process:

First, learn more about the use of plastic bags in life.

1. Ask children to gather the plastic bags they brought 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 by painting. (such as the situation that plastic bags are piling up like mountains, the scene that the earth is "submerged" by discarded plastic bags, and the phenomenon that plastic bags pollute the environment, etc. )

Third, discuss ways to reduce the pollution of plastic bags.

1. The pollution of plastic bags is so serious, is there any solution?

2. When children propose to replace plastic bags with baskets, paper bags and cloth bags, please ask children to talk about the benefits of using these bags and why. The basket is durable and washable; Paper bags are easy to carry, pollution-free and recyclable; The cloth bag can be cleaned and reused. )

3. 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 the plastic bag in the soil, but it will slowly decompose into a toxic substance, which will destroy the soil and plant growth; The other is to burn the plastic bags, but at the same time, it will produce toxic gases, pollute the air and harm human health. Neither method is ideal.

fourth, ask the experts about it.

1. Ask the children to ask the experts boldly about the pollution of plastic bags and its treatment.

2. Experts are invited to introduce the current scientific methods to solve plastic bag pollution: substitution method and recycling method.

3. Teacher's summary: Plastic bags will bring serious pollution, so we should promote the use of cloth bags and paper bags instead of plastic bags. Another method 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, and the preset goals are basically achieved. Children have a strong interest and cooperate with me very tacitly. Children have a basic understanding of the harm of plastic bags and set up a preliminary awareness of environmental protection. "Pollution" lesson plan 3

Theme goal:

1. Know that waste gas is the waste of environmental pollution through various activities.

2. Know some causes of air pollution and its adverse effects.

3. Cultivate children's interest in learning, have a certain awareness of environmental protection, and stimulate children's environmental protection feelings.

4. Take an active part in activities and speak your mind boldly.

5. Cultivate children's ability to think, solve and respond quickly.

Theme:

1. Secrets of air

2. Clean air

3. Mother Tree

4. Know the no-smoking sign

5. Smoking is harmful to health

6. Environmental protection minibus

7. Save small animals

Create a reading area: < p

Science Zone:

Provide cotton, test tubes, cigarettes and other experimental supplies. One large basin for each group, straws, wool, transparent glue, plastic bags, plastic cups of clay tablets, glasses, matches and candles. (Operate under the guidance of teachers and do a good job in experimental safety) 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, and 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 contents of environmental protection festivals such as World Environment Day, Arbor Day, Bird-loving Week, Earth Day, No Tobacco Day and Ozone Day.

Parents' work:

1. Collect videos 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. Give lectures on environmental protection.

4. It is suggested that the grade group issue a "Letter to Parents", which clearly shows the significance of the theme, the content of the activity, the work that parents need to cooperate with and the relevant matters needing attention (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 be caring and responsible when getting along with animals in activities.

First of all, according to the cognitive characteristics of the second-year students, I organically integrated the course contents, and determined the focus of the teaching materials as starting from the small animals around the students. Through close contact with the small animals, the students clearly want to be true friends with animals, and they must have love and responsibility, and the education of "love" runs through the whole teaching process. Secondly, students are always the main body of learning activities. In teaching, through each group's close contact with 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 eating food, they can understand the fish in the activity, cultivate students to be close to animals, love animals and share happy feelings 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. The course "Morality and Life" advocates "returning to life". Before the end of the new course, I let students raise small animals, scattered students can raise chickens and ducklings in their own yards, and students living in buildings can raise small goldfish and turtles at home. Let children know more about how to be 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 objectives:

1. Make children understand the pollution and harm caused by 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. I am willing to try boldly and share my experience with my peers.

5. In 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 and waste paper in the soil, dig them up after a period of time, and observe and compare their changes.

knowledge and experience about garbage classification, recycling and recycling.

physical objects, experimental materials, word cards and pictures.

Activity process:

1. Show plastic bags and disposable foam utensils and organize children to talk:

◎ Where are these plastic bags and disposable foam utensils most used?

◎ How do you feel about using plastic bags and disposable foam utensils?

◎ Teacher's brief summary: These things are most used in markets, shopping malls, fast food restaurants and other places, and they are light and convenient to use. However, is it good to use these things?

2. Understand the characteristics that plastic bags and foam articles are difficult to decompose, and understand white pollution.

◎ Ask children to listen to the story "Uncle Zhang's Trouble".

◎ Guide children to classify the garbage according to Uncle Zhang's method (classify the word cards with the names of the garbage): recyclable and decomposable, and finally leave plastic bags and foam supplies.

◎ Discussion: Why does Uncle Zhang have worries and troubles about plastic bags and foam products? Guide children to recall the experiment of plastic bags and other garbage buried in the soil, knowing that plastic bags and foam products are difficult to decompose when buried in the soil. Ignite waste paper, plastic bags and foam products respectively, and 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 recycled into useful things; Rubbish such as peels and leaves can be decomposed into fertilizers under the action of sunlight, rain, air and microorganisms. However, 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, and occupy land, making human land less and less. The pollution and harm caused by plastic bags, foam appliances and other environments, we call it white pollution, which has brought many troubles to mankind.

3. Find ways to reduce white pollution.

◎ Ask children to look at the pictures and talk about whether people's behaviors on the pictures help reduce white pollution? Why?

◎ Ask children to 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 tell their own ideas.

◎ 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 from childhood and grow up to create lightweight and convenient environmental protection products.

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 up next Monday to observe and compare their changes. On the second day of the assignment, Chen Jialong, who is usually not active, came up to me happily in the morning and said loudly, "Teacher Xia, yesterday my father and I did the experiment together." I touched his head, nodded approvingly and praised him.

Next Monday, I just came to the classroom, and Chen Jialong has arrived. He excitedly ran over to tell me what he found: plastic bags and disposable foam utensils remained the same, and peels, leaves and waste paper were rotten.

It can be seen from this that as long as children are educated in their homes, their progress will be great. For example, Jialong usually doesn't like studying, and his attention is easily distracted in class. This time, due to the participation of parents, the children's enthusiasm has been improved at once, and their learning momentum has also increased.

activity reflection:

this activity mainly makes children understand the pollution and harm caused by discarded plastic bags and foam appliances to the environment, and enhances their awareness of environmental protection. Before this activity, we made a lot of preparations, and asked parents and children to do experiments at home first: bury plastic bags, peels, leaves, disposable foam utensils, waste paper, etc. in the soil, dig them up after a while, and observe and compare their changes. And explain some kinds of garbage to children.

In the activity, the children's knowledge and experience have been developed, and the discussion process is quite enthusiastic, with different methods. At last, the children are still unfinished, so I have to say that we will continue the discussion next time. "Pollution" big class teaching plan 5
