1, to help children understand the function and basic characteristics of gas and know that gas is harmful to health.

2. Educate children not to tamper with the gas switch casually and establish a sense of self-protection.

Focus of activities:

Understand the function and basic characteristics of gas, and know that gas is harmful to health.

Activity difficulty:

Children should not tamper with the gas switch casually, and establish a sense of self-protection.

Activity preparation:

Pictures of gas stoves and gas bottles.

Activity flow:

First, guide the children to look at the pictures.

Teacher: Teacher Zhu brought a picture. Do you know that?/You know what? What is this?

Teacher: Where have you seen it? What's the use?

The teacher concluded that gas cylinders are used to hold gas. The gas is transported to the gas stove through the pipeline. Turn on the switch, light the fire, and mom and dad can use it to cook.

Second, help children understand the basic characteristics of gas.

Teacher: Why can gas cook food?

Teacher: Can you see and smell the gas?

The teacher concluded: gas is a toxic gas, which will burn in case of fire. It was originally colorless and tasteless. In order to prevent people from being dangerous when using, the worker's uncle added an odorant when producing gas. When the gas leaks, people will find it as soon as they smell it.

Third, educate children not to tamper with the gas switch and learn some ways to protect themselves.

Teacher: What should we do when the gas leaks?

2, children according to their existing experience, the teacher finally concluded:

(1) The switch on the gas stove is the valve to control the gas in and out. Don't touch it casually. If this gas is put into the air, when people breathe into the body, it will cause gas poisoning, which will seriously endanger people's lives. Children should not play with it.

(2) When it is found that there is gas smell in the room, you should open the window quickly to let the air circulate, so that people will not cause hypoxia poisoning. After opening the window, you should also tell adults to check the gas leakage and repair it in time.

(3) Don't play with fire beside the gas bottle. After the gas bottle is heated, the pressure will increase, which will easily lead to explosion and fire if it exceeds a certain limit.

(4) After the soup and water on the gas stove are boiled, turn down or turn off the fire in time to avoid the things in the pot overflowing to crush the fire on the stove, and the gas keeps coming out, which is easy to cause gas poisoning.

3. Teacher: Gas poisoning is a very dangerous thing. We must learn to protect ourselves and our families! Don't panic when you encounter problems, think about how to solve them!

Fourth, end the activity.

Teacher: Today, we learned not to move the gas switch. Do you know the solution after the gas leak? You can share it with your parents when you go back!
