Snowstorm Safety Lesson Plan

Teaching purposes:

1. Know the dangers of snowstorms.

2. Know how to pay attention to traffic safety during snowstorms.

Teaching preparation:

Teaching platform and pictures about snowstorms.

Teaching process:

1. Introduction of new lessons

In winter and spring, there is often heavy snow weather. As students, we have to be on time. We go to school, but students don’t know much about the dangers of snowstorms and what issues they should pay attention to in such weather. In this lesson, we will learn this knowledge.

2. New Lesson Teaching

1. What is a blizzard?

In winter and spring, when strong cold air breaks out and moves southward, it is often accompanied by strong cooling and strong winds. When snow falls or strong winds roll up snow on the ground, the flying snow spreads with the wind, leaving a vast expanse of white with extremely low visibility. This is a "blizzard", and is known as "blowing snow" or "snowstorm" in meteorology.

2. What are the hazards of snowstorms

During snowstorms, due to increased non-evaporative heat dissipation, the body temperature of livestock will gradually drop after maintaining a thermal regulation balance for a period of time. According to measurements, in low temperature and windy environments, sheep can die when their body temperature drops to about 28°C. In spring. The pasture is withered and yellow, and the quantity is small and the quality is low. The animals are weak and in poor condition, and their ability to withstand the cold is reduced. When hit by a blizzard, not only does the herd become frightened and uneasy, but they often run wildly with the wind because they cannot discern the direction

and are unable to catch up in the circle. They often fall into the water in the lake or off the cliff. Fallen to death and freezes to death. Pregnant female animals running in adversity can easily lead to mechanical abortion; even in sheds, sheltered from the wind, snow and cold, often stacking on top of each other and squeezing each other for warmth, this can cause pregnant female animals to miscarry, and some may be crushed to death. Some young animals are even addicted to dirty snow or frozen pasture, causing the outbreak of malignant infectious diseases and leading to a sharp increase in the mortality rate of young animals. Therefore, blizzard is one of the disastrous weather conditions in animal husbandry production. From February to early April 1966, snowstorms occurred continuously in Ili, Tacheng, Altay and other areas of Xinjiang, with the snow depth reaching 25-45 cm. The maximum snow depth in Altay in February reached 73 cm, and the stable snow continued until April 16 The day just ended. The wind strength is generally level 6-7, and some can reach level 9-10. Blizzards and low-temperature snow caused the loss of 4.11 million livestock in Xinjiang, and the loss reached 1 million in the Altay region alone, accounting for more than 40% of the total in the region.

3. What issues should be paid attention to when traveling in snowstorm weather

Be careful to keep warm and cold; on the way to and from school, because the roads are slippery, be careful to prevent falling; stay away from vehicles, Keep to the right.

4. Play pictures of traffic accidents caused by snowstorms on the big screen to attract students' attention

5. Guide students to talk about their gains from this lesson
