Kindergarten safety teaching plan: beware of electric shock
Activity objectives:
1. Let children know that electricity can bring many benefits to people's lives, but it is also dangerous. Be careful to get an electric shock when using.
2, understand the preliminary knowledge of safe electricity use.
Activity preparation:
1, children's book.
2. Switches, sockets, wires, lamp holders, radios, etc.
Activity flow:
1, encourage children to talk about the role of electricity in life and stimulate their interest in learning.
Ask questions:
(1) What electrical appliances do you have at home?
(2) What convenience have these appliances brought us?
(3) What if there is no electricity?
Summary: We can't live without electricity. Household appliances need electricity; Electric lights can illuminate, and we can read and write at night; Electric fans can help cool down and dissipate heat; With TV, we can see the scenery all over the world, understand what is happening all over the world and learn a lot. There are also pumps and threshers, which can help farmers reduce their labor intensity. They are really good helpers. If there is no electricity in the gathering place, it will cause difficulties and inconvenience to our production and life. Therefore, we should not only understand electricity, but also pay attention to safe and economical use of electricity.
2. Organize children to read children's books and talk about the dangers of electricity.
Ask questions:
(1) Can you touch the socket and lamp holder with your hands?
(2) Can you touch the transformer and wires?
(3) Can you pull out the knife yourself?
Summary: No. Because electricity is input into electrical appliances through wires, and the wires are wrapped with plastic or rubber to prevent the transmission of electricity, we can hold it in our hands. But the inside of the appliance is charged, so it is not easy to get an electric shock when touched. Results The electric shock site was numb in light cases, burned in severe cases, and died in severe cases. So the danger of electricity is very great.
3. The teacher talked about simple ways to use electricity and measures to prevent electric shock.
(1) Show me the socket and tape recorder, etc.
Encourage children to introduce the experience of switching electrical appliances.
The teacher mainly explains how to use it. For example, how to hold, insert and connect the switch, as well as operating instructions.
(2) Let children further learn the measures to prevent electric shock to ensure safety.
(3) Our life is inseparable from electricity, so to use electricity safely, pay attention to the following points:
(1) Don't put wires, nails or fingers into the power socket, because the power socket is live.
② Don't go to places with transmission transformers and high-voltage lines.
(3) If you find a broken wire on the ground, don't pull it with your hands, but step on the thread with your feet, and immediately tell an adult to properly handle it.
Don't operate the electric switch yourself, but operate it under the correct guidance of adults.
2. Teaching plan of safety education and safe electricity use in kindergarten middle class
The first phase-the first phase of Z courseware B network activity goal: 1, so that children can initially understand the knowledge of electricity and know what is easy to conduct electricity and what is not easy to conduct electricity through experiments.
2. Cultivate children's independent thinking ability and interest in scientific exploration. 3. Educate children to pay attention to safe use of electricity in daily life.
Activity preparation: dry batteries, 1.5V electric beads, long wood chips, copper wires, nails, plastic bags, cloth strips, paper strips, rubber pipes, plastic pipes, wool, sorting boxes, etc. The number is equal to the number of children. Children know something about the positive and negative poles of batteries.
Activity flow: 1. Show materials to stimulate children's interest in hands-on operation. 2, children hands-on operation, explore the secret.
(1) explain the operation method. Children explore while operating. Put one end of everything on the negative side of the battery and the other end on the small light bulb on the positive side of the battery to see which one can make the light bulb light up and which one can't.
Think about why, and use sorting boxes to separate the results. (2) Children are free to learn and operate, and teachers tour to guide them.
(3) Let children discuss the calculation results with each other. (4) Please select children's representatives from each group and talk about their own operations.
3. Educate children to use electricity safely. The human body can conduct electricity. When inserting a plug, you should not touch the metal piece of the plug, put your hand into the socket, and even touch the power supply and wires casually.
3. How to prevent fire and electrical safety education teaching plan
How to prevent fire and electricity
1 class hour
Educational goal: to educate students how to save themselves and how to prevent electricity in case of fire. Educational process:
I. Fire
Fire and water are ruthless, and human nature. In the face of the critical moment of raging fire, we must adhere to the principles of "three necessities", "three rescues" and "three noes" in order to save the day and save the day.
1. "Three essentials"
(1) Be familiar with the environment where you live.
Pay more attention to observation at ordinary times, and know the stairs, passages, gates and emergency evacuation exits of the residence like the back of your hand, and know whether there are platforms, skylights and temporary shelters (rooms).
(2) "Think" to keep calm when something happens.
In the face of the raging fire, only by staying calm and calm can we quickly take decisive measures to protect ourselves and others. Some people make wrong actions because of confusion, which delays the precious time of escape. For example, I only know how to push the door, and I won't pull the door hard; Mistake the wall for a door and knock hard; Even whether you like it or not, you should touch the door before opening it. If the door is very hot or smoke has penetrated through the crack of the door, you can't open the door and prepare to take the second route. Even if the door is not hot, you can only open it a little carefully, pass it quickly, and then close it immediately. Because oxygen will come in when the door is wide open, even a smoldering fire will suddenly burn.
(3) "Beware" of drug abuse.
In the fire, the biggest "killer" is not the fire itself, but a large number of toxic smoke produced in the burning process, whose main components are carbon monoxide, hydrogen cyanide, hydrogen chloride, sulfur dioxide and so on. Fire experts' research shows that when the carbon monoxide content in the air is 1%, people will faint after breathing several times, and it will kill people in a minute or two. Experts suggest that you cover your nose and mouth with a wet towel and evacuate the fire as soon as possible. If the fire is too big and violent, the exit passage is blocked by smoke, and there is no other route to take, you can use a wet quilt as a cover, cling to the "seat belt" on the ground, and crawl in the corridors and rooms with dense smoke. Never run straight. Because hot and cold air is convective, toxic smoke floats on the upper part of the house space, and some fresh air will come in close to the ground for people to breathe. Standing and running is likely to be unable to breathe and suffocate. If your clothes are on fire, you should take off your clothes or roll on the ground to put out the fire. If someone runs away in panic and his underwear catches fire, he should be pushed to the ground and rolled until the fire goes out.
2. "Three rescues"
(1) Choose an escape route for "rescue"
In case of fire, it is the best choice to use stairs, evacuation passages and open stairs with weak smoke or unburned fire. If it can reach below the fire layer smoothly, it is basically out of danger.
(2) "self-help" when the rope slips.
What should I do when the corridor or stairs have been blocked by fire or poisonous smoke? We should use the rope in time (or tear the curtains and sheets into thick strips to form a long belt), and tie one end of the rope firmly to a load-bearing object, such as water pipes and heating pipes, and the other end hangs from the window to the ground or the balcony on the lower floor. Then he slipped down the rope and fled the fire.
(3) Seek "redemption" from the outside world.
If you are blocked in the building by fire and all escape routes have been cut off, you have to retreat indoors temporarily and close the doors and windows leading to the fire area. Staying in the room is not passive to die. You can water the doors and windows to slow down the spread of fire; At the same time, shout, wave, flashlight and throw things through the window. , send a distress signal, waiting for the rescue of firefighters. In short, don't do anything that is not conducive to escape because of impulse.
3. "Three noes"
(1) "No" Take the ordinary elevator
When a fire is discovered, people will pull the switch to stop the fire from spreading along the wires. Sometimes, the fire will burn the power line. If you take the ordinary elevator to escape, you will be in trouble in case of power failure. Being unable to go up and down is tantamount to trapping yourself in a "cage".
(2) Don't jump off a building easily.
The risk of jumping off a building to survive is very high. If you don't do it well, it is often either death or injury. You should not take it lightly. Even when you make this decision in despair, you should pay attention to the method. First of all, throw the quilt or mattress downstairs, so that when you land, you won't directly hit the hard cement or slate road, reducing the possibility of injury; Then grab the windowsill with both hands, droop, and jump with both feet to narrow the gap with the ground.
(3) "No" lust for property
The fire comes quickly, and it can enter the violent stage after 10 minutes. Therefore, fire experts remind that once a fire breaks out, you must evacuate and escape quickly, and don't waste time dressing up or looking for valuables, because there is nothing more precious than life. After escaping from the fire, don't even return to the crater for the sake of property. In the end, people and money can only be empty.
Second, how to use electricity safely:
(1), don't play with the plug of electrical appliances, please help plug it in and out if necessary.
(2) Don't touch the power switch with wet hands.
(3) Before learning to operate, you can't just press the knob and various buttons on the electrical appliance. Some household appliances can only be operated by adults and cannot be touched casually.
(4) Pay attention to saving electricity, turn off the lights conveniently, turn off the lights when no one is around, and turn off the TV in time after watching.

5. Electricity safety knowledge
In order to prevent electric shock and fire accidents caused by improper household electricity use, we have summarized ten "safety rules for household electricity use": (1) People should cut off the power supply when using electricity, and cut off the power supply temporarily when there is a power failure.
(2) Don't install the socket on the wall too low, and educate children to stay away from power supplies, switches and plugs. (3) When using the screw lamp, a safety ring should be installed on the lamp holder, and it is best to install a cable switch to avoid accidents caused by touching metal parts when switching the lamp.
(4) If the toggle power switch on the wall is damaged, it should be repaired in time. 5] When your hands are wet with water or sweat too much, don't touch the wire bolts and lights with the lamp holder switch.
[6] The electric furnace should be far away from the wires, so as to avoid the wires being burnt and burying hidden dangers. First, don't dry or hang clothes on the wire.
If the fuse is broken, don't replace it with iron wire, copper wire or aluminum wire. Don't touch the wire when it is damaged or broken. Disconnect the power supply in time, and then find an electrician to repair it.
⑽ If anyone is found to get an electric shock, connect the power supply with an insulator such as a dry stick first, so as to avoid dragging the electric shock without separating the power supply from the electric shock.
6. How to write a summary of the teaching plan for safe electricity use in kindergarten classes?
Activity objectives:
1, get a preliminary understanding of the basic knowledge of safe electricity use.
2. Enhance the awareness of self-protection by learning the knowledge of safe electricity use.
Focus of activities:
Understand the basic knowledge of safe use of electricity.
Activity difficulty:
How to protect yourself by using the knowledge of safe electricity use in life?
Activity preparation:
Teaching wall chart, a piece of wire with plug, a socket and an electric sign.
Activity flow:
Show the wires first and introduce them directly.
Look, children, what is this? See what's the difference between inside and outside.
Teacher: This is a piece of wire, with copper wire inside, which can conduct electricity, and plastic outside, covered with copper wire, which is a protective layer. With this protective layer, we have no electricity in our hands. But if the plastic is broken, we will run into electricity and be in danger.
Second, show the socket and introduce the relevant knowledge to the children.
Look, what is this? What's the use?
Teacher: This is a socket. It contains copper sheets and can conduct electricity. The outside is made of plastic and is considered as a protective layer. If you put your hand in, you will touch the copper sheet, and the electricity will be transmitted to people, which is very dangerous. Besides people and copper, water can also conduct electricity, so children can't touch the power supply with wet hands.
Third, discuss electricity consumption.
Teacher: Do children know what needs electricity in our life?
Yang: Electric lights, computers and televisions. . (Children casually answer)
Summary: People can't live without electricity. Electricity is very useful, but it will be very dangerous if it is not used safely.
Fourth, understand the basic knowledge of electricity, show the teaching wall chart one by one, and guide the children to observe it carefully.
What are the children doing in the picture? Did they do the right thing?
Five, guide children to combine life experience, talk about what should be paid attention to in the safe use of electricity in life.
1, just now we said that metal, water and people can conduct electricity, so children can't put their fingers into the socket hole of the power supply, and they can't touch the power supply with metal conductive things.
Question: What should I do if the wires at home are broken? (wrapped with special tape)
What should I do if I see a wire section on the roadside? (bypass)
2. Show the sign of "electricity" to let the children know.
If you see this electric sign on the roadside, you should stay away from it, don't touch it, don't go near it, and you can't climb it.
Activity expansion:
Children's operation information "Be careful with electricity" has a safety sticker.
Activity reflection:
After this class, the overall effect is ok, at least the children can master the content. Appropriate introduction before class stimulates children's interest. When I first started this course, I didn't think much about the children's answers. After all, children are innocent. They have unlimited imagination and give me unexpected answers. However, when the children gave strange answers, I didn't respond in time, which may have dampened their enthusiasm to some extent, and it is also my lack of adaptability in class. As a new teacher, this is what I need to improve.
7. The understanding of the class meeting on safe electricity use is 800 words.
Theme class meeting of electricity safety education
Teaching content: learn some safety knowledge of household electricity.

Home safety, pay attention to electricity. The fire has been lit, so don't trespass.
Don't mess up in a crisis, remember the exit.
Call 1 19 and wait for help. Jumping off a building is skillful, although it is harmful to survival.
8. Common sense of safe electricity use
1. Why does the lighting switch have to be connected to the live wire? If the lighting switch is installed on the zero line, although the light is not on when it is turned off, the phase line of the lamp holder is still on, and people will think that the light is not on and will mistakenly think that it is in a power-off state.
In fact, the ground voltage of each point on the lamp is still a dangerous voltage of 220 volts. If people touch these actually charged parts when turning off the lights, it will cause an electric shock accident.
Therefore, all kinds of lighting switches or switches of single-phase small-capacity electrical equipment can only be connected in series on the live line to ensure safety. 2. How to correctly install the single-phase three hole socket? Why? Usually, single-phase electrical equipment, especially mobile electrical equipment, should use three-core plug and its supporting three hole socket.
There is a special protective zero (grounding) jack in three hole socket. When using zero protection, it is very dangerous for someone to directly connect the wiring pile head of this hole with the zero line that only leads into the socket at the bottom of the socket. Because in case the zero line of the power supply is disconnected, or the fire (phase) line and the zero line of the power supply are connected reversely, its shell and other metal parts will also bring the same voltage as the power supply, resulting in electric shock.
Therefore, when wiring, the special grounding jack should be connected with the special protective grounding wire. When zero protection is adopted, the zero line should be led out from the power supply side, and the zero line introduced into the socket should not be used nearby.
3. Why is it forbidden to bury plastic insulated wires directly in the wall? (1) Plastic insulated conductor will age and crack after long-term use, and the insulation level will be greatly reduced. When the line is overloaded or short-circuited, it is easier to accelerate the insulation damage. (2) Once the wall is damp, it will cause a large area of leakage and endanger personal safety.
(3) Plastic insulated wires are directly buried, which is not conducive to line maintenance and repair. 4. Why should I use a leakage protector? Leakage protector, also known as leakage protection switch, is a new type of electrical safety device. Its main purpose is: (1) to prevent electric shock accidents caused by leakage of electrical equipment and electrical lines.
(2) To prevent single-phase electric shock accidents in the process of electricity utilization. (3) Cut off the single-phase grounding fault in the operation of electrical equipment in time to prevent electrical fire accidents caused by leakage.
(4) With the improvement of people's living standards, the number of household appliances is increasing. In the process of using electricity, personal electric shock and fire accidents caused by defects in electrical equipment, improper use and unfavorable safety technical measures have brought undue losses to people's lives and property. The appearance of leakage protector provides a reliable and effective technical means for preventing all kinds of accidents, cutting off power supply in time and protecting equipment and personal safety. 5. What is the main cause of electric shock accident? Statistics show that the main causes of electric shock accidents are: (1) lack of knowledge about electricity safety, flying kites near high-voltage lines and climbing high-voltage poles to dig nests; After the low-voltage overhead line is disconnected, connect the fire line by hand without power failure; Touch the charged body by hand for live wiring at night; Touch the broken rubber knife switch with your hand.
(two) in violation of the operating rules, without taking necessary safety measures, unauthorized connection of lines or electrical equipment; Touch damaged equipment or wires; Wrong installation of live equipment; Electrified lighting; Online maintenance of power tools; Live mobile electrical equipment; Twist a light bulb, etc with wet hands. (3) The equipment is unqualified and the safety distance is not enough; The grounding resistance of two-wire and one-ground system is too large; The grounding wire is unqualified or disconnected; Insulation damage to wires, etc.
(4) The equipment is in disrepair, the line is blown off by strong wind or the pole is not repaired in time; Rubber breaker bakelite is damaged and not replaced in time; The damage of the motor lead makes the shell charged for a long time; The porcelain bottle is damaged, which makes the phase wire and the pull wire short-circuited, and the equipment shell is charged. (5) Due to other accidental reasons, I walked at night and ran into a broken live wire on the ground.
6. What rescue measures should be taken in case of electric shock? When an electric shock accident occurs, while ensuring the rescuer's own safety, we must first try to make the electric shock victim quickly get rid of the power supply, and then carry out the following emergency repair work. (1) Untie the tight clothes that hinder the breathing of the electrocuted person.
(2) Check the mouth of the person who gets an electric shock and clean up the mucus in the mouth. If there are any dentures, remove them. (3) immediately on-site rescue. If breathing stops, rescue with mouth-to-mouth artificial respiration. If the heart stops beating or vibrates irregularly, use artificial chest compression to rescue it.
Never interrupt for no reason. If there is a second person besides the rescuer at the scene, the following work should be done immediately: 1) Provide first aid tools and equipment.
2) convince others at the scene. 3) Keep sufficient lighting and air circulation at the site.
4) Report to the leader and ask the doctor to come to the rescue. Experimental research and statistics show that 90% patients can be saved if treatment is started from 1 min after electric shock. Only 10% chance can save lives if rescue is started 6 minutes after electric shock; But from 12 minutes after electric shock, the possibility of saving lives is extremely small.
So if you find someone getting an electric shock, you should race against time and take all possible measures. 7. What measures are there to use electricity safely at home? With the popularization and application of household appliances, it is very important to correctly master the knowledge of safe electricity use and ensure the safety of electricity use.
(1) Don't buy fake and shoddy "three noes" household products. (2) When using household appliances, there should be a complete and reliable power cord plug.
Household appliances with metal shell should be protected by grounding. (3) Switches and fuses cannot be installed on the ground wire and zero wire.
It is forbidden to connect the ground wire to the tap water and gas pipeline. (4) Don't touch the live equipment with wet hands, and don't wipe the live equipment with wet cloth.
(5) Don't connect wires privately, and don't move live equipment casually. (6) When repairing household appliances, you must first disconnect the power supply.
(7) When the power cord of household appliances is damaged, it should be replaced immediately or wrapped with insulating cloth. (8) When household appliances or wires catch fire, disconnect the power supply first, and then put out the fire.
8. How to prevent burning household appliances? The rated voltage of common household appliances is 220 volts, and the normal power supply voltage is around 220 volts. If the power supply voltage in the power supply line rises instantly due to natural disasters such as lightning strike, the zero line of the three-phase unbalanced household line is broken due to years of disrepair, or the phase voltage rises due to human misconnection, the current will increase, and household appliances will burn out due to overheating.
To prevent the burning of household appliances, we should start from the following aspects: First, electrical equipment should be used when not in use.
9. Electricity safety knowledge
In order to prevent electric shock and fire accidents caused by improper household electricity use, we have summarized ten safety rules for household electricity use:
(1) When people go without electricity, they will cut off the power supply temporarily in case of power failure.
(2) Don't install the socket on the wall too low, and educate children to stay away from power supplies, switches and plugs.
(3) When using the screw lamp, a safety ring should be installed on the lamp holder, and it is best to install a cable switch to avoid accidents caused by touching metal parts when switching the lamp.
(4) If the toggle power switch on the wall is damaged, it should be repaired in time.
5] When your hands are wet with water or sweat too much, don't touch the wire bolts and lights with the lamp holder switch.
[6] The electric furnace should be far away from the wires, so as to avoid the wires being burnt and burying hidden dangers.
First, don't dry or hang clothes on the wire.
If the fuse is broken, don't replace it with iron wire, copper wire or aluminum wire.
Don't touch the wire when it is damaged or broken. Disconnect the power supply in time, and then find an electrician to repair it.
⑽ If someone is found to get an electric shock, connect the power supply with an insulator such as a dry stick first to avoid dragging the person who gets an electric shock without disconnecting the power supply.
