Teaching plan for safe use of electricity in kindergarten large classes

As an excellent people's teacher, it is inevitable to compile teaching plans. With the help of lesson plans, teaching methods can be properly selected and used to arouse students' learning enthusiasm. Come and refer to the lesson plan you need! The following is the teaching plan for the safe use of electricity in kindergarten classes that I have compiled for you. Welcome to reading. I hope you will like it.

Teaching plan for safe electricity use in kindergarten classes1;

1, in class, the teacher guides the children to understand the basic knowledge of safe use of electricity.

2. Children enhance their awareness of self-protection by learning the knowledge of safe electricity use.

3. Guide children to master the safe use of electricity in daily life.

4. Test children's reaction ability and exercise their personal ability.

Know how to save yourself in a dangerous situation.

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?

Young: electric light, computer, TV ... (children are free to 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.

Teaching plan for safe use of electricity in kindergarten class II Activity objective:

Activity preparation:

wall map

Activity flow:

1, on the basis of the teacher's questions, get a preliminary understanding of the use of electrical appliances:

(1) In our daily life, there are many electrical appliances. What electrical appliances do you know? What do they do?

(2) These electrical appliances have brought a lot of convenience to our life, but what can we do without them?

(3) Do you know where electricity comes from? (power station)

(4) Teacher's summary: Electricity has brought us a lot of convenience, and we can't live without it any more. Is our good friend, but this friend sometimes loses his temper and hurts people.

2. Show the wires and introduce relevant knowledge to the children.

(1) What is this? Where have you seen it? Take a closer look at the difference between inside and outside.

(2) Teacher's introduction: This is a wire with copper wire inside, which will conduct electricity. The outside is plastic and covered with copper wire, which is a protective layer. We have no electricity in our hands. But if the plastic is broken, we will run into electricity and be in danger.

3. Organize children's discussions

(1) What should I do if your home cable is broken? (wrapped with special tape)

(2) What should you do if you see a broken wire on the road? (bypass)

4. Show the socket and introduce the relevant knowledge to the children.

(1) What is this? What's the use?

(2) Teacher's introduction: This is a socket with copper wire or copper sheet inside, which can conduct electricity, and a plastic box outside, which is 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 connect electricity with wet hands.

(3) Show the signs of electricity to let the children know, know the signs of electricity, be vigilant and pay attention to safety.

5. Guide children to observe children's books. Look at the picture and say: What are the children doing in the picture? Did they do the right thing?

Activity reflection:

Handling of important and difficult points: I focus on students' theoretical derivation and experimental proof. Because students have the basis of P=UI, it is easy to draw the conclusion that I = P/U. When U is constant, the greater P is, the greater I will be. In particular, the reason for the increase of P is due to the close combination of the increase of household appliances and real life. The knowledge base of the current in the parallel circuit is equal to the sum of the currents in each branch, and it is not difficult to design the circuit through experiments. In the aspect of difficulties, the methods of demonstration, recalling old knowledge, investigation, inspiration, physical objects and charts are used to break through the difficulties. For example, when discussing fuses, first demonstrate the function of fuses in the circuit (protection circuit), and then deduce the principle of fuses (using the thermal effect of current) according to the observed phenomenon (fuse fusing). According to the resistance and melting point tables of various metals in the chart, the conclusion (lead-antimony alloy) is finally drawn by comparing students' thinking methods. The specification of fuse is obtained through fuse objects and tables, and the difference between coarse fuse and fine fuse specifications is clarified. The selection principle of fuse is expounded through demonstration tests. So the problems are solved one by one.

10 kindergarten class safety electricity teaching plan activity intention

Children in large classes have a strong desire to explore and like to try new things. The "magic" of household appliances often makes them want to operate. This activity takes the scene performance as the main line, so that children can learn to use several simple household appliances, guide children to understand the common sense of use and avoid the dangers in use.

moving target

1. Be able to use simple household appliances correctly.

2. Know how to operate according to electrical requirements, and don't touch the electrical button before use.

3. Feel the convenience that home appliances bring to people's lives.

4. Strengthen children's safety awareness.

5. Test children's reaction ability and exercise their personal ability.

Activities to be prepared

1. Teachers and children * * * collect portable small household appliances, such as small desk lamps, massagers, tape recorders, etc. , one or two in each group.

2. A number of radish strips (or fragile items), small electric fans, fruit juicers, and fruits.

3. Multimedia teacher resources: I can't do this.

Activity process

(a) the beginning part

Teacher: Today, the teacher has prepared many small household appliances for the children. Let's have a look!

1. Group observation, try to operate small household appliances, and understand that household appliances have switches.

2. Try to turn on the switch in turn and observe the changes of electrical appliances. Then ask a child to introduce the name and purpose of this group of electrical appliances and the changes of electrical appliances after turning on the switch.

(2) A case-a fan broke a child's finger to help the child understand the matters that should be paid attention to in the face of running electrical appliances.

1. The teacher tells a case and asks the children to tell why Xiaobo's finger is broken.

2. Field test: the power of the fan.

The teacher operates the small fan to put the radish strips into the fan, and the children observe the phenomenon that the radish strips are interrupted.

Summary: The fan blades are very thin, and rotate at high speed after being electrified, which makes the air flow into wind and makes us feel cool. But the rotating fan is like a blade, which can break the articles that extend into the fan. Therefore, the running fan is very dangerous. Children must not put their hands into the fan.

3. Tell me what other electrical appliances will work, and can I touch them when I work?

Summary: It is very dangerous to operate electrical appliances, such as washing machines, food processors and soymilk machines. Children should not touch running electrical appliances.

4. Play multimedia teaching resources to enrich children's common sense of safe use of electrical appliances.

(1) Teacher's narrative: Xiao Qiang saw that his mother was very tired after work and wanted to help her. But when he gets to the kitchen, he can't use the microwave oven or the water dispenser. what should he do ? What will happen if he moves by himself?

(2) Let children introduce the safe use of electrical appliances they know.

Summary: Every electrical appliance has requirements for safe use. Children must operate according to the requirements when using electrical appliances. Before learning to operate, you should not touch the electrical button casually, otherwise you may hurt yourself.

(3) Conclusion.

Teacher: Our children have mastered the use of electrical appliances, so let's make juice on the spot. Please let the children taste it together!

Activity reflection

Common sense of household appliances is a new course, that is, there are no teaching materials and reference materials, so the teaching difficulty can be imagined. In view of the situation that vocational school students are tired of boring explanations and like flexible and diverse practice plus practical teaching, a large number of media courseware and video materials have been accumulated in recent years, which have played an important role in teaching.

Practice teaching fully mobilized students' learning enthusiasm. They are not afraid of dirt and oil. They squatted underground and began to work, which was completely different from sitting in the classroom. Through practical training, students have a deep and extensive knowledge and are particularly easy to remember.

A few days ago, I made a phased assessment of the common sense of household appliances. I adopted a three-step assessment method:

The first step of the assessment is to fill in the blanks, not close the papers, so that everyone still has to memorize the basic knowledge by heart, accounting for 30 points.

The second step is to investigate the disassembly and assembly of the training, including the disassembly and assembly of the air conditioner and refrigerator. This assessment includes the correct use of electrical appliances, the standardized placement of disassembled items, and finally completely restored to the state when disassembled. Thirty-five points.

The third step is the common sense of using household refrigerators and air conditioners. By drawing lots, which one will be tested, this is an assessment method described while operating. Thirty-five points. It's a hundred points.

Through such teaching and assessment, I think it can not only cultivate students' good study habits of using their hands and brains, but also increase students' initiative in learning and make the teaching progress more complete.

3. Let the children see the teacher's hand posture and grasping position when holding the plug, and let the children know that there is electricity in the jack. The small copper piece on the plug can transmit electricity to the recorder through the wire, so the hand can't touch the copper piece, let alone reach into the jack.

4. Organize children to discuss: What should we pay attention to when using electricity? You should know that wet things can't get close to electrical appliances, which will lead to leakage. Electrical appliances should not be put together with flammable items such as paper and cloth, otherwise it may cause fire.

5. Let the children talk about what to pay attention to when using electrical appliances at home.

Activity expansion:

When walking. You can take your child to observe the signs of high-voltage electricity from a distance, and educate your child that high-voltage electricity is dangerous and must be kept away.

Electricity is an indispensable energy source in our life, but it is also very dangerous. We must teach children how to use electricity safely so as not to hurt themselves.
