Activity preparation:
1, using the half-month holiday, let students actually investigate the food stalls around the school and investigate what kind of food is safe through various channels.
2. Rehearse the sketch "He loves to buy snacks".
3、? I support environmental protection? Collection of.
Activity arrangement:
I. Food Hygiene and Safety
1, the host announced? Hygiene and health? The theme class meeting began.
2. Class teacher: Students! Today, our class held a meeting. Hygiene and health? Theme class activities. Have you learned through your own actual investigation or access to information? Food safety and hygiene? Knowledge of. I hope everyone will bring what they have seen, heard, thought and learned to today's class, so as to achieve the purpose of mutual communication and improve their safety and self-care ability.
The host asked the students to report the actual investigation results of the booths around the school.
4. Moderator's summary: Everyone's eyes are really bright! Careful observation, comprehensive investigation, and found many problems. Can our classmates not get sick after eating such food? Let's watch the sketch "He Who Loves Snacks".
5, sketch performance "He loves snacks"
Main content: during class, a boy suddenly had a stomachache and was sent to the infirmary. He was diagnosed as acute gastroenteritis by the school doctor. It is understood that he ate fried chicken legs on the street stall at school in the morning.
Class discussion: ① What happened to this boy?
(2) Why is he ill?
6. Moderator's summary: The school stipulates that you can't go to the stall to buy snacks, but some students buy them secretly and don't listen to the teacher's advice. The boy got sick because he ate the unsanitary food in the stall. So what kind of food is safe?
Students compare and discuss: safe food should have the date of production, the specific address and telephone number of the manufacturer, the shelf life, the specific composition and weight of the food, etc.
7. Moderator: We all know that illness comes from the mouth. In addition to the safety signs mentioned by students just now, we should develop good hygiene habits in our daily life. Moderator's question: What are the good eating habits?
Students discuss, teachers summarize tips:
(1), the food should be fresh and clean, do not eat rotten, spoiled and polluted food, and do not put clean food in unclean tableware.
(2) Wash your hands before and after meals, rinse your mouth after meals, do not do strenuous exercise after meals, and digest and absorb before meals.
(3) Eat regularly and quantitatively, chew slowly and eat less snacks.
(4) Food should be diversified, and picky eaters and partial eclipse will cause nutritional deficiency in the body and affect growth and development.
8. Wash your hands before and after meals, so how to wash your hands? Ask the teacher to show us, and we'll reach out and try.
First, soak your hands in water.
② Wipe the palm and the back of hand with hand sanitizer.
(3) Wrist rubbing, back rubbing and heart rubbing.
④ Wash the bubbles on your hands with clean water.
⑤ Finally dry your hands with a clean towel.
Second, for the healthy living environment around us (explained by the teacher)
1. Human health and environmental pollution
Environmental pathogenic factors: biological, chemical and physical factors.
The stages of environmental diseases: incubation period, symptom period, exposure period and dangerous period.
Characteristics of environmental pathogenicity: complexity and concealment
Types of environmental diseases: acute harm, chronic harm and long-term harm.
2. School environmental pollution
School site and environment. The air pollution in the classroom. The lighting problem in the classroom. Campus environmental sanitation.
3. Environmental pollution in family rooms.
Kitchen pollution, bedroom pollution, bathroom pollution, family public places pollution, family living room surrounding environmental pollution, dormitory environmental pollution.
4. Develop good living habits
Establish a sense of responsibility to protect the environment. Protect the environment, starting with me. Keep fit and set up ideals.
Third, environmental protection is around me.
1. Background: Since June, 2008, major shopping malls and supermarkets in China began to use disposable shopping bags for compensation, which aroused great concern of domestic consumers on environmental protection. If the previous measures focus on public opinion propaganda and ideological education, then this move is a concrete measure in the actual consumption process. Nowadays, under the background of modern material life, the concept and action of environmental protection have been deeply rooted in people's hearts. Environmental behavior starts with me? This class meeting with the theme of environmental protection can cultivate students' awareness of environmental protection, enhance their concept of environmental protection, and make environmental protection a conscious and spontaneous behavior in our daily life.
2. Relevant information:
(1) Collection of environmental protection propaganda words
Rainforest, the lungs of the earth. The last drop of water of mankind will be the tears of regret after environmental destruction.
Rational utilization of resources, protection of ecological balance and promotion of sustainable economic development.
Protect the environment, beautiful mountains and rivers, sustainable development and prosperity. Don't let lovely creatures disappear in our generation.
Respect nature and fear life. To heaven and earth, to heaven, to love.
Judge the beauty of heaven and earth and analyze the principle of everything.
Build a beautiful frontier and care for our home. Protecting the environment means protecting ourselves.
Protect the water environment and save water resources. Establish a great environmental awareness and protect the ecological environment.
Enjoy the wilderness and return to nature. Green hills clear my eyes, while flowing water calms my ears. What's in the mountains? There are many white clouds on the cen.
That water, that mountain, that mountain, is very close to people, endless and endless. There is only one earth, and mankind should be in the same boat.
Nature can't be improved, and life can choose green life and healthy and moderate consumption.
The earth can satisfy human needs, but it can't satisfy human greed.
A happy life lies not only in ample food and clothing, but also in clear water and blue sky.
Pursue green fashion and go green. Environmental pollution is condemned and environmental protection is praised by thousands of people.
(2) A few small things that can be done at will to protect the environment
1. Use a cloth bag:
When we go shopping in shops or farmers' markets, almost everything comes with plastic bags. When we get home, these plastic bags are often thrown into the dustbin immediately. As garbage, plastic bags have left our home, but they have not disappeared in this world. In most parts of our country, plastic bags can be seen everywhere. When the wind blows, they will fly in the air and land on branches and rivers, which will affect health and city appearance. Plastic bags increase the amount of garbage, occupy cultivated land and pollute soil and groundwater. What's more, plastics can't be degraded in nature for hundreds of years, and if burned, it will produce toxic gases. Just for a moment's convenience, but throw the garbage to future generations. Is this appropriate? Take Beijing as an example. If an average person consumes a plastic bag (about 0.4 grams) every day, 4 tons of plastic bags will be thrown away every day, and the raw materials alone are worth 40 thousand yuan. Small plastic bags are really harmful. We used to use reusable shopping baskets and cloth bags to buy food, but only in recent years have plastic bags been widely used. We should restore the fine traditions of the past. German young people are proud of shopping with bags. Shall we follow this? Green fashion? All right.
2 Try to take the bus:
1943, residents of Los Angeles, USA, found a white mist in the air, sometimes yellowish brown in color, which stimulated people's eyes to cry. This fog became more and more serious, but it was not until 10 years later that the real culprit car was found. There were two photochemical smog incidents in Los Angeles at 1955 and 1970. In the former, more than 4,000 people died of five senses poisoning and respiratory failure, while in the latter, 3/4 people in the city fell ill. From May to 65438+ 10 every year, under the strong sunlight, the exhaust gas emitted by automobiles forms photochemical smog, which causes eye diseases, laryngitis and headaches, reduces atmospheric visibility, and increases traffic accidents and plane crashes. Nowadays, the control of automobile exhaust has achieved considerable success, but the rapid increase in the number makes automobiles still the main source of urban air pollution. It is reported that photochemical smog pollution has also appeared in some big cities in China in recent years. Not only that, the process of making cars consumes natural resources, but also emits pollutants, and cars will also produce noise and other hazards. Moreover, more and more cars have caused great pressure on urban traffic and caused traffic congestion. These have seriously troubled our lives, and one of the solutions is to take fewer cars and advocate taking buses.
3. Try to use renewable materials.
Judging from the energy contained in the earth, nature has unlimited energy. As far as solar energy is concerned, the energy transmitted by electromagnetic waves from the sun to the earth per second is equivalent to the heat released by burning more than 500 tons of coal. This is equivalent to 65.438+0.3 trillion tons of coal heat in a year by solar energy alone, which is about 1 10,000 times of the current world energy consumption. However, the development and utilization of earth energy are still influenced and restricted by social productive forces, science and technology, geographical reasons, world economy, politics and other factors. The huge amount of energy, including solar energy, wind energy and water energy, can only be used in a small proportion, so there is great potential for continued development. The sharp increase of human energy consumption, the scarcity and exhaustion of fossil fuels and the worsening ecological environment force people to think about the energy problems of human society. The sustainable development of national economy depends on the sustainable supply of energy, which requires the research and development of new energy and renewable energy.
