"Terrible white pollution" big class teaching plan

"Terrible White Pollution" is mainly to let children know the pollution and harm caused by discarded plastic bags to the environment and enhance their awareness of environmental protection. The following is the lesson plan of "Terrible White Pollution" compiled by me. Welcome to refer to.

"Terrible White Pollution" Large Class Teaching Plan 1 Activity 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. Boldly participate in the discussion, clearly express your views and ideas, and develop the thinking of seeking differences.

4. Cultivate children's awareness of developing good living habits.

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.

Nowadays, children understand the harm of "white pollution". In the future, we should start from ourselves. When we go shopping, we can take bags from home and use environmental protection bags to reduce pollution. We should always remind our parents and people around us that we can 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.

The goal of "Terrible White Pollution" lesson plan activity in Big Class 2:

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.

The teaching plan of "Terrible White Pollution" in Big Class 3 Purpose:

1, let children know the pollution and harm of discarded plastic bags and foam products to the environment and enhance their awareness of environmental protection.

2. Cultivate children's interest in science and develop their imagination and creativity.

Prepare:

1, lead children to shops and fast food restaurants to observe the use of plastic bags and disposable fast food utensils.

2. Organize children to bury plastic bags, peels and leaves in the soil respectively, and observe and compare their changes after a period of time.

3. Slide "Harm of white pollution to the environment" and video "Trouble left by plastic bags and foam items".

Process:

1, organize a dialogue

(1) What do people usually use to wrap things when they go to the store? What plate does the fast food restaurant serve?

② How do you feel about using plastic bags and disposable foam? (Very convenient)

③ While they bring convenience to people's lives, what impact will they have on the environment?

2. Understand the characteristics of plastic bags and foam products that are difficult to decompose.

① Guide children to watch the video "Trouble left by plastic bags and foam items" and ask: Why do workers and uncles in garbage recycling plants classify garbage? What garbage can be recycled and what can't?

② Guide children to recall the experiment and talk about the different changes of peels and leaves in plastic bags and soil, and why?

The teacher concluded that waste paper and other wastes can be decomposed and recycled into useful things, while garbage such as peels, leaves and sewers can be decomposed into fertilizers under the action of sunlight, rain, air and microorganisms. However, plastic bags and foam items commonly used in life are not easy to decompose, which will pollute the environment and be harmful to people's health.

3. Know the harm of white pollution and try to reduce it.

(1) Light plastic bags and waste paper, guide children to observe, compare the differences between plastic bags and paper when burning, which one will produce strange smell and what it feels like after smelling.

② Watch the slide of "The Harm of White Pollution to the Environment" and talk about the harm of plastic bags and foam products to the environment and biology.

③ Teacher's summary: Because of the pollution and harm caused by plastic bags and foam products to the environment, we call it "white pollution".

④ Organize children to discuss how to reduce white pollution in daily life, and encourage children to use their brains and come up with more and better methods.

⑤ Guide children to tell their own solutions. For example, buy things with cloth bags and woven bags; Production of biodegradable environmental protection plastic bags.

⑥ Guide children to use their imagination and make related environmental protection posters.

Activity expansion:

Organize children to clean up discarded plastic bags and disposable fast food utensils in parks and seaside, and rehearse sketches about reducing white pollution.
