As a nameless selfless dedication of educators, from time to time to carry out the preparation of lesson plans, through the preparation of lesson plans can be better according to the specific circumstances of the teaching process to make the appropriate adjustments necessary. So how should a lesson plan be written to be appropriate? The following is my collection of gas safety education theme classroom lesson plans, I hope to be able to help you.

Gas Safety Education Theme Class Meeting Lesson Plan 1

Learning Objectives:

By learning about gas safety, students can establish the concept of self-care and self-help, form the awareness of self-care and self-help, and prevent some unnecessary accidents from happening.

Learning process:

I. Talk to introduce:

Students live in a happy, warm family, cared for by parents and family members, love and care, there does not seem to be any danger. However, there are still many things in the family life need to pay attention and careful treatment, otherwise it is very easy to danger, causing accidents. In fact, there are always safety hazards in our family, especially about the use of gas, we must always be vigilant.

Second, the safe use of gas knowledge transfer

1) gas appliances in the work, people can not be left for a long time, in order to prevent the wind blowing out or by the pot overflow of water, resulting in a large number of gas leakage and fire. (Explained by way of examples)

2) The use of gas appliances (such as gas stoves, gas water heaters, etc.), should be sufficient to ensure that the ventilation of the room, to maintain sufficient oxygen to prevent gas poisoning.

Specific questions relate to:

1) How to recognize gas leakage?

2) What are the symptoms of gas poisoning?

3) What measures should be taken for gas poisoning?

4) What is the danger of stacking things near the gas meter?

5) How to light the gas?

6) How to adjust the flame?

7) Maintenance of gas stoves

3. Let the students interpret some of the kitchen clips, so that they can learn how to save themselves and find out the problems and the measures to be taken.

4. Through the class meeting, students learned about gas safety and how to protect themselves and their families.

V. Summary of the class meeting

Teaching Objectives:

1.

3. Initially grasp the safety knowledge of gas poisoning prevention.

Teaching Focus: Understanding of gas poisoning and how to deal with it;

Teaching Difficulties: How to deal with gas poisoning;

Teaching Methods: Combination of Lecture, Discussion and Demonstration.

Teaching Strategies: Cooperative Learning in Groups

Teaching Process:

(A) Cutting to the chase, understanding the truth

Dear students, this semester, we will soon be facing the winter season, and cold winters tend to be a high incidence of gas poisoning. The slightest lack of attention may lead to danger and accidents. In order to enhance the students' awareness of safety precautions, improve our self-care and self-help ability, for which we have prepared this "anti-gas poisoning safety education" theme class meeting.

(Introducing the recent gas poisoning incidents reported by our province and city)

August 9 morning 9 Xu, xx High-tech Zone, Changling South Road in the middle of the non-motorized road, a man was found dead in a black SUV car, was found to have been over three or four days. High-tech branch garden police station rushed to the scene, immediately in the vehicle around the cordon, after forensic investigation at the scene, initially confirmed that the man has died, the deceased body without obvious trauma. The forensic identification, to determine the cause of death of the man Department of the car in a closed state, open the air conditioning led to inhalation of excessive carbon monoxide unfortunately died.

The case of gas poisoning: Shaanxi xx: home funeral accident, a house of five people poisoned was put down (play the news report video)

The case of gas poisoning: Shaanxi 11 elementary school girls died of gas poisoning (play the news report and related video)

(B) to tell the new lesson:

1, the subject: the gas poisoning safety education board book

2, ask: gas poisoning occurs in what season?

3, question students: raise your hand to answer.

4, the teacher commented: gas poisoning usually occurs in the fall and winter seasons, because of low temperatures, low air pressure, poor indoor air circulation in the fall and winter seasons, the most likely to lead to gas poisoning accidents. Of course, there are also gas poisoning accidents in the summer, more often when we use air conditioning.

Student activity: group inquiry learning:

I. Principles of gas poisoning? Board

1, group discussion, the students in each group according to their own from the news, newspapers and other sources know the principle of gas poisoning to discuss;

2, the teacher asked the groups.

Teacher's comments:

1. Gas poisoning usually refers to carbon monoxide poisoning. If the carbon monoxide content in the air reaches 0.04%-0.06%, it can make people poisoned.

2. Carbon monoxide is colorless and tasteless, and often invades the human respiratory tract unknowingly under accidental circumstances, especially during sleep, enters the bloodstream through gas exchange in the alveoli, and spreads all over the body, causing poisoning.

3. The binding capacity of hemoglobin and carbon monoxide in the blood is more than 200 times stronger than that of oxygen, and the separation of hemoglobin and oxygen is very slow. Therefore, once a person inhales carbon monoxide, oxygen will lose the opportunity to combine with hemoglobin, so that the tissue cells can not get enough oxygen from the blood, thus making the human body lack of oxygen, resulting in breathing difficulties.

4, the symptoms of carbon monoxide poisoning time, the severity of poisoning and carbon monoxide in the indoor concentration of closely related, but also with the age of the poisoned. Young people are more sensitive than the elderly, pregnant women, obese people and people with chronic heart and lung diseases are also prone to poisoning.

Doctors remind: carbon monoxide poisoning on the brain nervous system and palpitations damage, resulting in blood supply blockage, the body lack of oxygen, high disability rate, easy to cause delayed encephalopathy, treatment recovery is very difficult.

Student activities: group inquiry learning:

Second, the causes of gas poisoning? Board

1, group discussion, students in each group on the causes of gas poisoning;

2, the teacher asked the groups.

Teacher's comments:

Common causes of gas poisoning ?

(1) The use of coal stoves for heating and cooking in a closed room can produce a large amount of carbon monoxide accumulation in the room due to poor ventilation and insufficient oxygen supply.

① doors and windows closed, and no ventilation measures;

② carelessness, paralysis, resulting in a large number of gas overflow;

③ chimney installation is not reasonable, the mouth of the tube to the wind, so that the gas backflow;

④ bad weather conditions, such as wind, snow, cloudy days, low pressure, the gas is difficult to circulate discharged.

(2) Urban residents use piped gas or liquefied petroleum gas. If the pipeline leakage, the switch is not tight, or cooking in the flame is extinguished, the gas overflow, can also cause poisoning.

(3) The use of gas water heaters, poor ventilation, bathing time is too long.

(4) In winter or summer, starting a car in the garage or starting the car air-conditioning after sleeping in the car can cause gas poisoning. Because the car exhaust contains carbon monoxide, a 20 horsepower car engine can produce 28 liters of carbon monoxide in one minute.

Third, the symptoms of gas poisoning? The symptoms of gas poisoning

1. Mild poisoning. The symptoms of gas poisoning are: dizziness, headache, blurred vision and general weakness. If you can open the window in time and inhale fresh air, the symptoms will be reduced and disappear soon.

2, moderate poisoning. Poisoned people can appear sweating, irritability, walking unsteadily, pale skin, fuzzy consciousness, always feel sleepy, sleepy and weak, if you take effective measures, the basic can be cured, rarely leave sequelae.

3, heavy poisoning. At this time, the poisoned person has been confused, teeth closed, the whole body twitching, incontinence, face and lips now cherry red, respiration, pulse rate increases, blood pressure rises, heart rate is not synchronized, lungs have a roar, body temperature may rise. Extremely critical people can continue to deep coma, weak pulse, irregular respiration, blood pressure drops, may also appear high fever of 40 degrees Celsius, at this time life-threatening, high mortality rate. Even if you are lucky enough to be alive, you will be left with serious sequelae.

Fourth, how to quickly deal with gas poisoning accident board

(with animation, to help students understand

Methods / Steps

1, open the window for ventilation

If you find that there is a phenomenon of gas poisoning, or self-perception of such a situation, hasten to the first time to open the doors and windows of your indoor poisonous gas emitted out, so that the fresh air flow Come in, if you find that the poisoned person appears to be unconscious or dizziness close to coma, be sure to send the poisoned person out of the house.

2, relax clothing

encounter gas poisoning, if they are still awake, loosen their own collar, so that they get better breathing. If you find a poisoned person, then the ambulance crew rushed to loosen the patient's clothes, pants belt, etc., and pay attention to keep warm.

3, clean up the mucus in the mouth

After the gas poisoning, we should clean up the mouth of the poisoned person, especially the comatose patient, because once the gas poisoned person, will involuntarily flow to the mouth and nose of some bodily fluids, which is easy to cause the patient's breathing is not good, and lead to more serious consequences.

4, feed some sugar tea water

If the poisoned person still have their own consciousness, can still have the ability to swallow, hurry to prepare a cup of sugar tea water, for the patient to drink, so that the patient to replenish the appropriate strength, waiting for further treatment.

5, artificial respiration

If the patient is found unconscious, or weak call, the patient's mouth and nose cleaned up after the patient's artificial respiration treatment, when the fresh air into the patient's body, the poisoning is not too serious patients will be able to alleviate some of the symptoms, but must master the correct way.

6, contact the hospital

If the poisoning is not too serious, only dizziness, nausea, the face does not look good phenomenon, that will be the above kinds of only way to implement the patient to move to the house full of fresh air and not cold lying down to rest can be, when the patient appeared to be unconscious, accelerated heartbeat, or more serious symptoms, it must be rushed to contact the hospital for professional treatment, not to be taken lightly. The first thing you need to do is to get your hands dirty.

Student activities: simulation exercises

If your group of students in the bath, gas poisoning, how to first aid?

Warm tips: 1. one person pretending to be gas-poisoned;

2. 1 meter away from the scene of the poisoned person can be;

3. the leader of the group carefully organized, reasonable division of labor.

Scenario 1: When you take a bath with a gas water heater yourself, you feel dizzy, headache, blurred eyes, and general weakness.

Scenario Design 2: A student was poisoned while taking a bath with a gas water heater and experienced excessive sweating, irritability, unsteady walking, pale skin, blurred consciousness, and vomit in the mouth.

Scenario 3: A student was poisoned while taking a bath with a gas water heater, with sweating, irritability, unsteady walking, pale skin, blurred consciousness and fever.

Scenario 4: A student was poisoned while taking a bath with a gas water heater, and showed excessive sweating, irritability, unsteady walking, pale skin, blurred consciousness, coma, or dizziness close to coma.

Scenario 5: A student was poisoned while taking a bath with a gas water heater and became unconscious with rapid heartbeat and weak breathing.

(Guiding students to operate in accordance with the correct method)

( Rescue poisoning as soon as possible Poisoning caused by gas water heaters is often due to a lack of vigilance, sometimes unknowingly, if not controlled, the development of symptoms of poisoning is more rapid. Therefore, once found that someone is poisoned, must be rescued as soon as possible.

1, quickly close the valve, open the door and window ventilation, so that the poisoned person as soon as possible from the scene;

2, the poisoned person's head flat, so that their breathing is not impeded;

3, pay attention to warmth, to avoid cold and lead to lung infections aggravate the disease;

4, the mouth of if there is vomit, wrapped in a finger of clean cloth gently wiped, so as not to enter the pharyngeal cavity caused by the choking;

4, if there is vomit, wrapped in a finger, gently wiped cloth, so as not to enter the pharynx cavity Asphyxiation;

5, the poisoned person appears high fever, available ice packs or towels cold compresses;

6, the lesser poisoning can drink a small amount of vinegar or sauerkraut water, so that it quickly wake up;

7, if the poisoned person's face is purple, limbs are cold, respiration stops, should be carried out immediately mouth-to-mouth respiration;

8, if the poisoned person's heart has stopped beating, the artificial respiration should also be done with chest compressions. If the poisoned person's heart has stopped beating, artificial respiration should be carried out at the same time with chest heart compression. And should be in the shortest possible time and emergency doctors to get in touch).

V. How to prevent gas poisoning:

1. Prevent gas pipes and gas stoves from leaking.

2. Prevent the gas from being doused after it is lit, which leads to a large amount of gas leakage.

3. Use the gas water heater correctly

4. Maintain indoor air circulation. Never use coal, charcoal, firewood, coke and other combustible materials to heat indoors without a chimney.

6, driving, do not let the engine idle for a long time; car in the stop, do not open the air conditioning unit for too long; even when driving, should often open the windows, so that the car inside and outside the air convection. Feeling uncomfortable that stops to rest; driving or riding in an air-conditioned car such as dizziness, sinking, limbs, should open the window in time to breathe fresh air.

Six: collective discussion:

Question: What did we learn in this class? What should we do in the future?

Teacher summary: to prevent gas poisoning, prevention is the main. As long as students have a strong sense of security, most gas poisoning accidents can be prevented. I hope that through this anti-gas poisoning safety education class will enable students to raise vigilance, enhance safety awareness, master gas poisoning self-help skills, and hope that students can stay away from accidents, every day peace and happiness!

Seven, homework

1, go home, and family members to find home what is easy to gas poisoning safety hazards, the day to solve, to ensure a safe, warm winter.

2, the knowledge we learned today to speak to their parents and people around you to listen to, everyone strive to prevent soot, gas poisoning volunteer publicizer.

3, to do a "prevention of gas poisoning safety education" of the blackboard newspaper or handbill for publicity.

Teaching Reflection: The teaching of this section of the class basically achieved the teaching objectives, improve students' awareness of safety precautions; students know how to save themselves when faced with gas poisoning; but also a preliminary grasp of the safety of knowledge of anti-gas poisoning. Teaching the whole process of student enthusiasm is very high, the degree of participation is relatively high, is a more successful classroom lesson.
