teaching process
(A) class profile
The latest news According to the statistics of the total disaster situation in Guangdong Province, from June 5 to 8, seven cities, namely Heyuan, Huizhou, Shanwei, Zhongshan, Yangjiang, Maoming and Yunfu 19 counties (cities, districts), 177 towns and 150 * * were affected by heavy rainfall, and Yangjiang was affected.
According to the disaster report of the provincial defense general in the early morning of June 9, heavy rain in Xinyi City, western Guangdong Province caused local flash floods and landslides, and 1 person died in the landslide. According to preliminary statistics, Xinyi * * * has 19 townships, with 385,000 people affected, 368 landslides, 186 road collapses, and 156 houses collapsed, resulting in a direct economic loss of 68.5 million yuan.
(2) Teaching new courses
1, understand the concept of rainstorm.
Heavy rain with strong intensity. The rainfall per unit time is called rainfall intensity. China's meteorological department stipulates that: 24-hour rainfall is greater than or equal to 50 mm for heavy rain; Heavy rain occurs when it is greater than or equal to 100 mm; It's a rainstorm of 200 mm or more. Rainstorm is a kind of disastrous weather, which often causes floods and serious soil erosion, leading to major economic losses, such as engineering accidents, dike breaches and crop flooding.
2. The danger of rainstorm.
Rainstorms come quickly and violently, especially large-scale persistent rainstorms and concentrated rainstorms, which not only affect industrial and agricultural production, but also may endanger people's lives and cause serious economic losses. There are two main hazards of rainstorm:
(1) Flood disaster. Due to heavy rain and poor drainage, it is easy to cause waterlogging, and the soil pores are full of water, which leads to the lack of oxygen in the roots of terrestrial plants, inhibits the physiological activities of the roots, strengthens the anaerobic process, produces toxic substances, harms crops and reduces production.
(2) Flood disaster. Floods caused by heavy rain flooded crops, making it difficult for crops to metabolize normally and causing various injuries. The deeper the flooding, the longer the flooding time and the more serious the harm. Flash floods and river floods caused by heavy rains not only endanger crops, fruit trees, forestry and fisheries, but also destroy farmhouses and industrial and agricultural facilities, and even cause human and animal casualties and serious economic losses.
(3) Discussion
Recently, there has been continuous heavy rainfall in Huizhou, and heavy rains often fall in some areas, resulting in disasters in some areas of Huizhou. Born in Huizhou, what measures should be taken to prevent some hazards caused by heavy rain? Self-rescue measures of rainstorm and flood
In a short period of time, the continuous rainstorm in an area will cause the river to rise violently, overflow dams, flood farmland and villages, and destroy roads, bridges and houses. This is a flood disaster. How should we save ourselves when the flood comes?
(l) Under the threat of flood, if there is enough time, it should be organized to move to hillsides, highlands and other places according to the predetermined route; In the case of being caught off guard and surrounded by floods, we should use boats, rafts, door panels, wooden beds, etc. Let the water transfer as much as possible.
(2) When the flood comes too fast to move, you should immediately climb the roof, tall buildings, big trees and high walls, take refuge temporarily and wait for rescue. Don't swim alone.
(3) In mountainous areas, if there is continuous rainstorm, mountain torrents are prone to occur. In this case, we should pay attention to avoid crossing the river and being washed away by mountain torrents, and also pay attention to preventing landslides, rolling stones and mudslides.
(4) It is found that the high-voltage tower topples, and the wires drop or break; Stay away from danger, don't touch or get close to it to prevent electric shock.
(5) After the flood, it is necessary to take medicine for epidemic prevention, do a good job in health and epidemic prevention, and avoid infectious diseases.
(4) class summary
Rain is a common weather phenomenon, but continuous heavy rain, even heavy rain, is a natural disaster! Students must strengthen the prevention of heavy rain in their daily lives. As long as everyone has a full sense of safety, pay attention to prevention, pay attention to the rise of water level in thunderstorm days, and take timely measures, we can turn the corner.
(5) Task
1. According to the content of this lesson, tell parents the safety knowledge of preventing rainstorm after class;
