5. Have a preliminary understanding of the common sense of smog prevention.

Activity preparation:

1. Before class, children have been asked to draw all kinds of smoking pictures (exhaust gas from buses and cars, exhaust gas from factory boilers, smoke from firecrackers, dust from construction sites, smoke from burning grass in farmland, etc.). ), small experiments (plastic bags and glass jars: lighters for cars, wood and houses, some waste paper, PPT and weather videos).

Activity flow:

First, conversation activities: the importance of feeling the air

1, talk about weather record observation

Today, Teacher Chen came to your kindergarten. The teacher found your kindergarten very beautiful. Before that, I want you to record today's weather. Who wants to talk?

(Ask two children to introduce his records)

Teacher, here are some weather signs. Which one should be used to represent sunny days? What other signs indicate the weather?

Second, look at all kinds of wall charts and cards about smog weather to understand the impact of various smog weather on human beings.

Teacher, here are some photos. What kind of weather do you think they are in? What weather signs are used to indicate this kind of weather?

What kind of weather is this? Then let's listen to what meteorologists have to say. What did the children just hear? (More than 3 children answered)

Is this weather indicated by the weather sign above? (sunny, cloudy, rainy)

It turns out that there was no such weather before, but it just happened recently. Then why is there such weather? (The child answers)

Then let's take a look at what caused the picture.

The teacher concluded: Does this smoke have any effect on our environment?

Then watch the teacher do a little experiment.

Third, games, demonstrations and visual displays.

Glass jar scene:

(1) Car Forest House

We live in a beautiful city with blue sky and white clouds, and we breathe clean air. Where is the air (the air is around us)? What will happen to the air we breathe when we have more factories, cars, burning trees and straws?

(2) making smoke

What do you see: Are the two bags filled with the same air?

The teacher concluded: What's in the air? The teacher filled the air with plastic bags. There are black spots in the second bag. Let's take a look at this kind of air that originally contained PM2.5 particles. The particles are very small.

Fourth, feel the importance of air quality.

Are these particles easily inhaled by us?

We breathe through our noses. We have nose hair in our noses. When we breathe, these nose hairs can block large particles, while small particles are easily inhaled into our bodies.

Once inhaled, what harm does it do to human body?

There will be respiratory irritation, cough, dyspnea and other diseases.

The teacher concluded that particles harmful to human health are easily blocked by the nasal cavity and throat. However, because PM2.5 is a tiny particle, once inhaled, it will cause respiratory irritation, cough, dyspnea and induce many diseases. If there is foggy weather, how should we protect ourselves when we go out? Wear a mask, go out less, and don't open the window for ventilation.

Today, the teacher taught you a breathing method in foggy days. The teacher demonstrated.

The children followed the teacher to relax and breathe. (breathing method. Put your hands together on your chest, then straighten your arms forward and slowly lift them to your head. While doing the action, you can do the breathing methods of "three breaths in one breath" and "three breaths in one breath", that is, three breaths and one breath. Changing one breath into multiple breaths for exercise can improve the immune function of respiratory tract, increase vital capacity and enhance the hypoxia tolerance of human body. )

How should we protect the environment from such bad weather?

(Car-free Day on September 22nd, lights out for one hour at 20: 30-2 1: 30 on March 23rd)

Our country has taken the following measures: car-free day (reducing the emission of automobile exhaust), greening our environment on Arbor Day, turning off the lights for one hour (saving electricity) and so on, all of which are for us to breathe better air and have a better living environment. We want to protect the environment, everyone is responsible!

Verb (abbreviation of verb) conclusion

Let's go back to class immediately and discuss with other children in the class what other methods can protect the environment and reduce the occurrence of such bad weather. Let's say goodbye to the visiting teacher!

Teaching reflection:

In the whole activity, children's curiosity was used to stimulate their interest in learning, which achieved the expected purpose and the effect was very good, even exceeding the expected effect. The whole activity not only made the children experience the happiness when the experiment was successful, but also enhanced their self-confidence, and also knew the necessity of protecting the environment. At the same time, it also cultivated children's observation and hands-on ability. It is very meaningful and necessary to carry out this activity in large classes.

Encyclopedia: Haze is a combination of fog and haze. Smog is very common in cities. In many areas of China, fog and haze are combined as disastrous weather phenomena for early warning and forecasting, which are collectively called "haze weather". Haze is the result of interaction between specific climatic conditions and human activities.
