How to use electrical appliances safely? Nowadays, more and more household appliances such as televisions, refrigerators, washing machines, electric irons, hair dryers, and electric fans have entered homes.
When using household appliances, in addition to paying attention to the safe use of electricity, you should also pay attention to the following points: 1. Various household appliances have different uses and methods of use, and some are more complicated. General household appliances should be learned to use under the guidance of parents, but dangerous appliances should not be used alone.
2. If you find that the appliance emits smoke, sparks, or a burnt smell during use, you should immediately turn off the power switch and stop using it. 3. Hair dryers, rice cookers, electric irons, electric heaters and other electrical appliances will emit high heat during use. Care should be taken to keep them away from flammable items such as paper and cotton to prevent fires. At the same time, care should be taken to avoid burns when using them.
4. Avoid using electrical appliances in humid environments (such as bathrooms), and do not let electrical appliances get wet or damp. This will not only damage the electrical appliances, but also cause the risk of electric shock. 5. The blades of electric fans and the dehydration drum of washing machines rotate at high speed during operation. Do not touch them with hands or other objects to prevent injury.
6. In the event of a thunderstorm, stop using the TV and unplug the outdoor antenna to prevent lightning strikes. 7. If electrical appliances are left unused for a long time, they are easily damaged by moisture and corrosion. They need to be carefully inspected before reuse.
8. When purchasing household appliances, choose qualified products with reliable quality.
2. Ask teachers to help and teach children about electricity
Electrical energy can be converted into heat energy and light energy based on the thermal effect of current;
Electrical energy can be converted into Mechanical energy is based on the magnetic effect of electric current
The conversion of electrical energy into magnetic field is based on the magnetic effect of electric current
The conversion of electrical energy into chemical energy is the chemical effect of electric current
Electric energy is converted into Sound energy is based on the magnetic effect of electric current
Then just make a video about it
Electric energy can light up light bulbs, cook, and produce magnetism. Just give an example.
Just make a slideshow and add some pictures, animations, videos, etc.
Don’t tell children something so profound, they won’t understand and will be too lazy to listen.
First, give examples of the actual effects of electricity so that they can have an understanding of electricity, and then proceed to the generation process of electricity, thereby introducing the concept of energy and energy conversion! For example, triboelectricity is a common example of rubbing fur with a glass rod to produce static electricity that attracts hair. Do some small experiments on site to give them a personal experience! The key for children is to let them know it, it doesn’t have to be too profound! You can also promote safety knowledge and tell them about the dangers of electricity!

5. How to teach children some common sense about electricity safety
The safety of children has always been a concern for parents, especially during holidays when children are alone When you are at home, electrical safety has become one of the biggest hidden dangers at home. Children are curious by nature and like to explore everywhere at home, but "electricity" is something that needs to be used with caution and discipline. How to teach children some common sense about electricity safety?
How to teach children about electricity safety knowledge
1. Teach children how to use electrical appliances
Educate children to pay attention to safety and explain the dangers of tampering with electrical appliances. Do not mess around with electrical equipment when adults are not around.
However, after the child becomes sensible (over 5 years old), the child can be taught how to use some common electrical appliances, allowed to use them under the guidance of an adult, and often reminded not to use hard objects, especially metal objects, to dig into sockets and sockets.
2. Clear signs of electricity use at home
When the children at home are too young and don’t know how to distinguish them, you can set clear safety signs at home and use colors to give them a sense of safety. The distinction between what can be touched and what cannot be touched allows children to divide areas in the home in the simplest way.
For example, put obvious red signs next to switches and sockets, and put green signs next to sofas and lamps to inform children that red areas in the home represent danger and green represents safety, so when the children are at home You will also know which places need to be avoided, and it is easy to distinguish between movable and immovable locations indoors.
3. Understand the harm to the body caused by electric shock
Metal objects are conductive and should not be used in direct contact with the power supply. Some babies are very curious and will often use their little hands or a piece of wire to test the socket. This is very dangerous. Parents should pay special attention to their children's every move and seek prompt treatment in case of electric shock.
4. Teach children the common sense of first aid for electric shock
After children become sensible, they should know the function and position of the main power switch and learn to turn off the main power supply in an emergency. Let the children know that when they find someone getting an electric shock, they should try to turn off the power in time. Do not use your hands to directly rescue people. Call an adult for help. Do not handle it yourself to prevent electric shock. Let children know that dry wood, rubber, and plastic are non-conductive and are insulators. These tools can be in direct contact with the power supply and will not cause electric shock. You can use dry sticks and other objects to separate the person who gets an electric shock from the live electrical appliances, or you can stand on a dry Pull the electrocuted person's clothes from the wooden board.
How to prevent children from getting electric shock
1. Pay attention to the location of iron wire, knives and scissors
Place conductive items such as iron wire, knives and scissors out of reach of children Where to take it; do not put towels, clothes, etc. on the wires.
2. There should not be too many electrical appliances in children's rooms
There should not be too many electrical appliances in children's rooms, especially in the rooms of younger children; floor-standing appliances should be avoided. Electrical appliances to prevent children from getting electric shock after tripping.
6. Tomorrow I am going to teach "Safe Electricity Knowledge" to kindergarten children. Is there anyone who can provide me with it?
Scenario exercise: Suddenly a man appeared in a corner of Huang Kefang's house. There was smoke and a burning smell
Discuss with children how to use electricity safely
1. Look for signs of smoke (it turns out that Huang Kefang used an electric iron to iron clothes for fun. Forgot to turn off the power and burned the clothes)
2. Discuss with young children how to use electricity safely at home? Ask children to express their opinions. At this time, dexterous guiding language should be used to develop children's imagination and judgment of things
3. The teacher summarizes how to use electricity safely:
(1), Don’t play with electrical plugs. Ask everyone to help plug and unplug them when needed
(2) Don’t touch the power switch with wet hands
(3) Don’t press the electrical appliance casually before you learn how to operate it. Only adults can operate the knobs and various keys on household appliances and do not move them randomly
(4) Pay attention to saving electricity and turn off the lights when no one is around. Turn off the TV in time after watching it.
