Everyone is responsible for forest fire prevention. Teaching objective: 1. Understand the important role of forests.
2. Understand the hazards of forest fires.
3. Understand some basic fire prevention knowledge.
4, understand the fire alarm telephone and fire alarm method.
Teaching preparation: forest pictures; Photos after the fire.
Teaching process:
(1) Look at the picture and introduce the new lesson.
Show beautiful pictures of the forest.
Teacher: Students, are these pictures nice? Do you know what they are? Yes, they are forests, and they are our friends for human survival. Do you know what forests do?
(2) The important role of forests. (Students speak freely, and the teacher gives a summary)
1, forest is the purification of air.
2. Forests have natural epidemic prevention functions.
3. Forest is a natural oxygen factory.
4. The forest is a natural muffler.
5. Forests can regulate climate.
6. Forests can change the low-level airflow, prevent sandstorms, reduce floods, conserve water sources and maintain soil and water.
7. Forests can remove dust and filter sewage.
8. Forest is the habitat of many kinds of animals, the growth place of many kinds of plants, and the most active area of biological reproduction on the earth.
However, due to fires, deforestation and land reclamation, especially fires, the forest area is gradually decreasing, and some plants are on the verge of extinction. Our friends will gradually leave us. So what are the hazards of fire?
(3), the harm of forest fire. (Data collected by students before lectures, summarized by the teacher)
1, forest fire can not only burn many trees, reduce stand density and destroy forest structure; At the same time, tree species are replaced by low-value tree species, shrubs and weeds, which reduces the forest utilization value.
2. Because the forest is burned and the woodland is exposed, the function of water conservation and soil and water conservation of the forest is lost, which will lead to other natural disasters such as floods, droughts, mudslides, landslides and sandstorms.
3. The growth of forest trees in the burned area decreased, which provided a favorable environment for the breeding of forest diseases and insect pests and accelerated the death of trees. After forest fire, the forest environment changes dramatically, and the forest ecology such as weather, water and soil is disturbed and out of balance, which often takes decades or hundreds of years to recover.
4. Forest fires can burn all kinds of production facilities and buildings in forest areas, threaten villages and towns near forest areas and endanger the safety of people's lives and property in forest areas. At the same time, forest fires will kill and drive away precious animals. When a forest fire breaks out, it will also produce a lot of smoke and pollute the air environment. In addition, fighting forest fires consumes a lot of manpower, material resources and financial resources, which affects industrial and agricultural production. Sometimes it causes personal casualties and affects social stability.
Teacher: Forest fire is one of the most harmful forest disasters. According to the International Forest Fire News jointly published by FAO and the Economic Commission for Europe, since the 1980s, there have been about 255,000 forest fires in the world, with an average annual forest or other woodland area of 6.367 million hectares. The data does not include countries that are not counted (such as some countries in Southeast Asia and Africa). The actual number and area of forest fires are much higher than the above data, and the burned area accounts for about half of the 20 million hectares of forests lost every year in the world, accounting for 0.2% of the total forest area in the world? 0.3%。 Due to the influence of climate change, in recent years, fires are raging all over the world, and forest fires are on the rise. At the end of 1990s, with the arrival of long-term drought, fires moved eastward from Africa, from north to south, from Eurasia to Southeast Asia, destroying millions of hectares of tropical forests and seriously damaging the ecological balance in this region and even the whole world. 1The catastrophic forest fire in Daxinganling, China on May 6, 1987, the fire in Yellowstone National Park in the United States on May 6, 1987, and the fire in Amazon rainforest on May 6, 1987, especially the Indonesian fire that started at the end of June, 1987 and lasted for 0 months.
China is also a country with serious forest fires. According to statistics, since the founding of New China, there have been 705,000 forest fires in China, with 38.74 million hectares of forest affected, 33,000 people burned and hundreds of billions of direct economic losses. 1987 The forest fire in Daxing 'anling burned for 27 days and nights, and the burned area was1330,000 hectares. The burned forest is equivalent to the whole forest area of Hainan Province, resulting in 2 13 deaths, 226 injuries and more than 56,000 homeless people. 1From March 28th to April 3rd, 986, two forest fires occurred in Selongji, Anning County, Yunnan Province and Tongguan, Yuxi City, covering an area of 32,000 mu. 15,000 people participated in the fire fighting, with casualties 179 people, including 80 victims.
(4) Prevention of forest fires.
The key fire prevention period in our district is from June 10 to May 1 the following year. As a pupil, what should I do? Students discuss and report in groups.
1. Be a good volunteer propagandist, vigorously publicize the Forest Law, Forest Fire Prevention Regulations and other forestry laws and regulations, raise the awareness of parents and the surrounding people, and ensure that laws are strictly enforced.
Don't play with lighters, matches, candles, etc. Don't set off fireworks in the wild.
3. No open flame enters the forest area.
What should I do in case of fire? First of all, calm down, don't panic, quickly evacuate the fire and don't put out the fire. Call the fire alarm? 1 19? Let professionals put out the fire. Remember to tell the exact location of the fire, the size of the fire, whether there are toxic and harmful substances, and whether there are people trapped or injured when reporting the fire.
(5) Review and summary.
What did you gain from this class? Tell the students!

Teaching process:
First, import
Fire, what is it? Holy? Yes Materials. It is something that everyone is most familiar with and often comes into contact with; However, it is a substance that hurts everyone the most. Although you need it for cooking, have you heard about the harm of fire to the forest? Teachers often talk about its harm at morning meetings. Many criticisms were published in the newspaper. Who can give an example?
Second, analyze forest fires.
1, what is a forest fire:
Forest fire refers to the behavior that forest fire is out of human control, spreads and expands freely in woodland, and brings certain harm and loss to forest, forest ecosystem and human beings. Forest fire is a kind of natural disaster with strong suddenness, great destructiveness and great difficulty in disposal and rescue.
2. Talk about the causes of forest fires.
(1) incineration; (2) refining mountains for afforestation; (3) burning ashes and accumulating fertilizers; (4) burning the ridge; 5) burning straw; [6] Smoking and littering cigarette butts in forest areas; (7) Picnics and barbecues in forest areas; (eight) burning paper, incense, candles and firecrackers in forest areas; (9) Hunting with guns in forest areas; ⑽ Cars entering the forest area spill oil and fire.
3, the harm of forest fire:
(1) Forest fire can not only burn many trees, reduce stand density and destroy forest structure; At the same time, it also causes tree species succession, which is replaced by low-value tree species, shrubs and weeds, reducing the value of forest utilization.
(2) Because the forest is burned, the forest land is exposed, and the function of water conservation and soil and water conservation of the forest is lost, which will cause other natural disasters such as waterlogging, drought, mountain torrents, mudslides, landslides and sandstorms.
(3) The growth of forest trees in the burned area decreased, which provided a favorable environment for the reproduction of forest diseases and insect pests and accelerated the death of trees. After forest fire, the forest environment changes dramatically, and the forest ecology such as weather, water and soil is disturbed and out of balance, which often takes decades or hundreds of years to recover.
(4) Forest fires can burn all kinds of production facilities and buildings in forest areas, threaten villages and towns near forest areas, and endanger the safety of people's lives and property in forest areas. At the same time, forest fires will kill and drive away precious animals. When a forest fire breaks out, it will also produce a lot of smoke and pollute the air environment. In addition, fighting forest fires consumes a lot of manpower, material resources and financial resources, which affects industrial and agricultural production. Sometimes it causes personal casualties and affects social stability.
Third, prevent forest fires:
1, forest fire prevention, strict control of fire source is the key.
2, collective efforts, forest fire prevention.
3, strict investigation and strict management, forest safety is guaranteed.
Fourth, the story of loving the forest.
1, talk about how to love forests and nature since childhood.
2. Develop a good habit of loving the forest and nature from an early age.
Verb (abbreviation of verb) consolidates and expands.
