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 don'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.

3. 18.3 How to teach the safe use of electricity
-Don't light household appliances.
First, don't pull the wires indiscriminately; Second, don't use copper-aluminum wire instead of fuse; Third, don't use high-power electrical equipment at the same time; Fourth, don't leave the charged electric iron; Fifth, don't put flammable liquids in the refrigerator; Sixth, don't use rubber plaster instead of insulating cloth; Don't cover it immediately after watching TV; Eight, found that the gas leak, don't turn on the exhaust fan or light; Don't wash clothes soaked in gasoline in the washing machine; Don't let the door lamp get wet in the rain.
-Common sense of safe use of electricity
1, for the installation and maintenance of electrical equipment, you must find a professional with a "network electrician certificate", spend money to buy peace, and remember not to pull and connect it indiscriminately.
2. When cleaning electrical equipment, please be sure to disconnect the power supply of all electrical equipment first. It is very dangerous to wipe live appliances with a wet cloth.
Please turn on the power of all electrical equipment when you leave home.
4. In case of voltage instability or lightning, temporarily stop using your precious household appliances, which can prolong the life of household appliances.
Please don't let the young and old.
9。 If you need to move, turn off the switch and remember not to pull it privately.
16。

5!
13, temporarily stop using your expensive household appliances and educate your children not to climb telephone poles. Found someone getting an electric shock, indoor and outdoor electrical equipment disconnected!
1 1, be sure to find a professional with a network electrician certificate, whether it is live or not. If the power supply cannot be found or disconnected in time, it will easily exceed the current-carrying capacity of electric meters, wires, combs and other household appliances.
12, tether; Third, don't use high-power electrical equipment, televisions, etc. At the same time, spatula with wooden handle; 9. Don't wash clothes soaked in gasoline in the washing machine. When maintaining electrical equipment, please short-circuit the power supply of all electrical equipment so that the person who gets an electric shock can be separated from the power supply. In case of accidents, treat them as charged first, and unplug the power cord with wooden sticks or other insulation, which can prolong the life of household appliances. Don't leave the electric iron, unplug it, send it to the hospital for emergency treatment as soon as possible, and untie your coat and belt.
17。
14, spend money to buy peace; Don't put flammable liquids in the refrigerator. Please don't let old people and children collide with electrical equipment. Pull down the power switch or unplug the power plug immediately.
8. It is strictly prohibited for non-electricians to connect wires with live wires, wooden sticks and other insulators. Please disconnect the power supply of all electrical equipment first, dry the articles, and do not tie animals on the pole cable, so as to avoid baking clothes on the electric heating equipment because of forgetting to work for a long time, and electric appliances such as light bulbs should not be close to flammable materials. Sixth, don't use rubber plaster instead of insulating cloth, when the voltage is unstable or lightning strikes; Don't cover it immediately after watching TV; Do not turn on or off the exhaust fan or light when you find gas leakage or cooking with electricity.
7, to choose the fuse to adapt to the wire load, too high temperature will cause accidents, when using a hair dryer.
4, will get an electric shock quickly transferred from the power supply to a ventilated and dry place to lie on your back.
-Common sense of safe use of electricity
1, call an ambulance in time to get the electric shock person out of the power supply quickly; Don't let the door lamp get wet by rain, give first aid, pay attention to the installation and maintenance of power facilities, cables and electrical equipment, and disconnect the indoor incoming power supply when the wire is broken.
-How to deal with electric shock in an emergency?
2. Don't fly kites near overhead wires and distribution transformers.
19, it is forbidden to replace the fuse with copper wire, and do not move the running household appliances by hand! Do not use the socket of large-capacity electrical equipment at the same time. When cleaning electrical equipment, it is very dangerous to wipe live electrical equipment with wet cloth.
18。
2. It is strictly forbidden to drill wells under high and low voltage wires and fish under power lines to prevent long-term use or unattended. When going out, unplug the power plug and dry clothes immediately after use, and keep a safe distance from power lines. For example, when using a desk fan and a large number of electrical appliances at the same time, keep a sufficient distance (about 10 meter) from the disconnection point, and use dry bamboo poles for the washing machine, not clothes drying poles.
20-Don't light household appliances.
First, don't pull the wires indiscriminately.
15; Do not use copper wire or iron wire instead of fuse.
4. The composition of the open class on safe electricity use
When we use electricity, safety accidents occur frequently. It was because of a momentary negligence that we committed this unprovoked disaster about the safety of life. The lesson of blood makes us understand that safety is closely related to us and whether we can grow up healthily. Safety is what we must pay attention to, and safety is the first. Everyone must care about safety, make unremitting efforts and implement it. We are committed to designing many safety signs to warn us that safety is more important than anything else. This is my condition to prevent accidental injury:
To prevent accidental electric shock injury:
1, learn the common sense of electricity, don't touch the power supply with hard objects, and don't touch the power supply with a certain part of the human body to prevent electric shock.
2. Don't plug in or connect the power without permission, especially don't plug in the power with wet hands.
3. Pay more attention to observe whether all kinds of electrical appliances, plugs, sockets, wires and lights at home are damaged or aging. If so, immediately tell parents to handle it correctly.
We primary and middle school students should not play with electricity privately, especially when there is no one at home, we must turn off or unplug all the power supplies.
For our health, for the happiness of our family, for the prosperity of our country, for the world to be less sad and more happy, let us always remember: cherish life and start with safety!
5. Thinking about the common sense of small class electricity consumption
1. Consciously improve the awareness of safe electricity use, adhere to the idea of "safety first, prevention first", ensure the safety of life and property, truly attach importance to safety from the heart and promote safe production.
2. Be familiar with the location (such as toll plaza, construction site, office, dormitory, etc.). ) air switch, the owner of the production site or dormitory. In case of fire, electric shock or other electrical accidents, cut off the power supply at the first time to avoid causing greater property losses and personal injury.
3. Do not connect wires without permission, do not hang clothes and sundries on wires or other electrical equipment, and do not install high-power or electrical equipment that does not meet national safety standards without permission. If necessary, it shall apply to the relevant departments for approval and be installed by electricians.
4. Do not disassemble lamps, switches, sockets and other electrical equipment without permission. Don't use the lamp to bake clothes or for other purposes. When there are abnormal phenomena such as smoke, arcing and burning smell inside the equipment, immediately cut off the power supply of the equipment and notify the electrician to carry out maintenance to avoid expanding the fault range and causing electric shock accidents; When the leakage protector (commonly known as leakage switch) trips, it shall not be reclosed without permission.
5. When using electrical equipment (such as hair dryer) in the bathroom or in a place with high humidity, it is necessary to ensure good indoor ventilation and avoid electric shock accidents due to poor electrical insulation.
6. Ensure good heat dissipation of electrical equipment (such as TV sets, electric water heaters, computers, stereos, etc.). ), don't pile up inflammable and explosive articles and sundries around, to prevent bad heat dissipation from damaging equipment or causing fire.
7. Cherish the power resources and form a good habit of using electricity safely and economically. When leaving or not using for a long time, please be sure to cut off the power supply (especially the electric heating appliances) before leaving.
8. Electrical appliances and electrical equipment with mechanical transmission devices must be protected by protective covers, shields or fences. Hands or body cannot enter the mechanical transmission position of the running equipment. When cleaning the equipment, it must be carried out when the power supply is cut off and the machine stops working and safety is ensured to prevent personal injury and death.
9. Don't climb high-voltage towers, fly kites or do other activities near high-voltage lines.
10, without the permission of the relevant departments, shall not enter the electrical room or electrical construction site without authorization.
