What should I do if a thunderstorm comes?

The lesson plan for what to do when the thunderstorm comes in the big class is as follows:

First, teaching focus: the principle and process of lightning formation, clear the harm of thunderstorm weather, and establish lightning protection safety awareness.

Second, teaching difficulties: emergency treatment methods and emergency measures after lightning strike.

Third, the teaching process:

1, know lightning

1) The teacher plays videos of lightning and thunder to the students during the thunderstorm season and asks,' What is this phenomenon? Have you ever experienced this weather? How did you feel then? "

2) Students exchange lightning knowledge according to their life experience.

3) Teacher's guidance: "Lightning is a common natural phenomenon in life, and we often encounter thunderstorm weather in our life. Do you know how lightning is formed? "

4) Students introduce the relevant knowledge they know first, and then teachers supplement it with the introduction of textbooks. You can use scientific experimental equipment such as generators to demonstrate the principle of lightning generation for students.

2, correctly understand the harm of lightning.

1) The teacher introduced: "The temperature of lightning is as high as 2000℃. Imagine what kind of danger this temperature will bring?

2) Students communicate the hazards of lightning according to their own understanding.

3) The teacher concluded: "Clouds can accumulate a lot of positive charges, and the earth is a conductor, which accumulates negative charges, thus causing high potential differences between clouds and between clouds and between clouds and the ground, ranging from several million volts to hundreds of millions of volts. The generated current is very strong, reaching tens of thousands to hundreds of thousands, forming high heat and strong light, which will cause great harm and cause people to die immediately. If you pass through trees and buildings, huge heat and air vibration will cause them to be seriously damaged. "

4) Experience the hazards of lightning according to real cases.

Knowing the case of "real reproduction" of the textbook, the teacher asked, "Have you ever thought about such serious consequences? Do you think there will be such danger when we encounter a thunderstorm? "

Students exchange their understanding of this incident and talk about the knowledge and understanding of lightning disaster in combination with their own life experiences. Teachers provide more cases of lightning strikes for students, helping students to understand lightning more comprehensively and clearly and pay attention to its harm.

Fourth, organize the data.

1. Teachers guide students to sort out the collected data and the lightning hazards learned through study.

2, students exchange gains.

Verb (abbreviation of verb) Prevention of lightning strike in the field

1, the teacher introduced:' When we go to school, it is common to go out to play and encounter thunderstorms after school, so what should we do if we encounter thunderstorms outside?

2. Students communicate according to their own life experience and relevant knowledge, and teachers supplement relevant materials in the teaching materials.

1) Problems needing attention in lightning protection and rain protection.

2) Matters needing attention when using rain gear.

3) Pay attention to whether your clothes are easy to cause danger.

4) Avoid using electronic products.

5) Do not engage in dangerous activities.
