Compiling teaching plans is an important preparation for teachers to carry out teaching tasks. The main purpose of compiling teaching plan is to achieve the best teaching effect. So how to write the lesson plan of "safe use of electricity" in small classes? The following is the lesson plan of "Safe Use of Electricity" in a small class that I have compiled for you. I hope you like it!
Small class "Safe electricity use" teaching plan (1) activity name:
Safe electricity
Activity objectives:
1, understand the purpose of electricity, and know that there is no danger in using electricity safely.
2. Understand the basic knowledge of safe use of electrical appliances through identification activities.
3. Enhance self-protection awareness.
4. Guide children to master electricity in daily life.
5. Obey the rules of social behavior and don't do "forbidden" things.
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 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 flow of "Safe Electricity Use" teaching plan in small class (Chapter 4);

4. Guide children to master the safe use of electricity in daily life.
5. Strengthen children's safety awareness.
Activity preparation:
1, children's operation card.
2. A few wires and sockets.
Activity flow:
1. Ask questions to arouse children's interest in talking and inspire them to talk about the use of electricity.
(1), it was dark and nothing could be seen. What should I do if I want to read at this time?
(2) The weather is very hot, and I want to work in a cool environment. What should I do?
There is a lot of dust on the carpet in my room. I want to clean it. What should I use?
(4), lamps, electric fans, air conditioners, vacuum cleaners, what do you need to make them work?
(5) What other things need electricity in our life?
Summary: Electricity has so many uses, it brings us a lot of convenience, and we cannot live without it more and more. Is our good friend, but this friend sometimes loses his temper and hurts people.
2. Ask the children to take out the operation card, guide them to observe and discuss, and help them understand the superficial knowledge of safe use of electrical appliances.
(1), Question: Did this bear do it right? What will happen if this is done? Why?
Show a wire, let children observe its basic structure and function, let children know that the inner layer of the wire is copper wire, which can conduct electricity, and the outer layer is plastic, covered with copper wire, which is a protective layer, and it has no electricity. If the protective layer of the wire is damaged, people may come into contact with electricity, which will bring us danger.
(2) Question: What is this rabbit doing? Is this the right thing to do What will happen?
Show a socket, let children observe the basic structure and function of the socket, let children know that there are copper sheets or copper wires in the socket, and the outer layer is a box made of plastic, which plays a protective role. If you put your hand or something into the jack and touch the copper, electricity will spread to us and hurt us.
(3) Question: What is the child doing? What will happen if you do this?
Summary: Water can conduct electricity. If electrical appliances are used in wet places, electric leakage will occur.
3. Summary:
Electricity has brought us many benefits, but if we don't use electrical appliances correctly, it will bring us danger. Therefore, children must pay attention to the safe use of electricity and remind people around them to use electricity safely.
Small Class "Safe Electricity Use" Teaching Plan (Chapter 5) Safe Electricity Use (PEP textbook)
(A) teaching purposes
1. Keep in mind the safe voltage value and use electricity safely (PEP textbook).
2. Know the cause of electric shock and several forms of electric shock.
3. Understand the common sense of safe electricity use.
(2) Teaching AIDS
Slide projector, several projection slides related to the application of electricity, self-made projection slides (or illustrations) of teaching materials10-1and10/3, and teaching materials10-/kloc-.
(3) Teaching process
1. Introduce new courses
The teacher told everyone through examples that with the development of science and the popularization of household appliances, electricity is indispensable in modern life. Then use the slide projector to make several slides about electricity consumption: for example, at night, the classroom lights are bright and students read books under the lights; The Tiananmen Gate in the festival is decorated with lights. Large-scale power grid, etc. Stimulate students' emotions.
The teacher turned the topic to the constant electric shock accidents, which brought irreparable losses to the country and individuals. But electric shock accidents can be avoided. If we master the principle of safe electricity use and strictly follow the requirements of electricity use, we can tame electricity and make it our good friend to serve our life, industrial and agricultural production and national defense science and technology. So, how can we use electricity safely? What is the principle of safe use of electricity? This is what we will discuss in this class today.
Step 2 take a new lesson
(1) Q: Do you know what an electric shock is?
Guide the students to look at the first question and answer in the textbook. Then the teacher pointed out that because the human body is a conductor, when the human body touches a charged body, a current passes through the human body. This is an electric shock. The harm of current to human body is related to the magnitude of current and the length of electrifying time.
(2) Q: Will people die if they get an electric shock? What is the cause of the electric shock accident? What is the safe voltage value?
Guide the students to look at the second question and answer in the textbook. Then ask the students to discuss the following questions:
(1) According to Ohm's law, what does the current in a conductor relate to?
② Touch the positive and negative poles of a dry battery with both hands. Why didn't there be an electric shock accident?
(3) What does the current through the human body depend on?
④ What is the safe voltage value?
Teacher's summary:
① The current passing through the human body depends on the applied voltage and the resistance of the human body;
② safe voltage: Only the voltage not higher than 36 volts is safe;
The voltage of the household circuit is 220 volts, and the voltage of the power supply circuit is 380 volts.
④ Electric shock accident is caused by excessive current passing through human body. The greater the current passing through human body, the longer the power-on time, and the greater the danger.
(3) Q: How did the electric shock accident happen in the home circuit? (Two forms of low-voltage electric shock)
Guide students to read the third question and answer in the textbook. Obviously, electric shock accidents in home circuits are caused by direct or indirect contact between human body and live wires.
Then guide the students to observe the textbook diagram 10- 10, and let them point out the current loop in Figure A and Figure B. Then the teacher points out two forms of electric shock:
Single-line electric shock (Figure A): People standing on the ground touch the live wire, and the current enters the human body from the live wire to the ground, forming a loop through the ground wire, resulting in an electric shock accident. Jump to the electronic textbook
Double-wire electric shock (Figure B): If a person stands on an insulator and touches two wires at the same time, the current will enter the human body from the live wire to the other wire (neutral wire) to form a loop, thus causing an electric shock accident.
It is pointed out that in order to use electricity safely, never touch the uninsulated live wire and the conductor connected with the live wire.
(4) Common sense of safe use of electricity in home circuits
Guide students to read the fourth and fifth questions and their answers in the textbook. Then ask: What should we pay special attention to when using electricity in China?
Student A: Pay special attention to the fact that objects that are insulated are charged, and objects that should not be charged are charged.
Teachers print out four pictures of 10- 1 1 in the textbook with slides (or show a wall chart), and ask questions by pointing to the pictures. If you make a picture with slides, the teacher points to the picture and asks: What is this phenomenon? What other such phenomena are there in life? How to prevent it? Students discuss and answer.
Teacher's summary:
(1) Pay attention to prevent the insulation from being damaged.
(2) Keep the insulation dry, do not use wet manual switches, and do not hang clothes on wires.
(3) When someone gets an electric shock, cut off the power supply first, or open the wire with an insulator such as dry wood.
④ When installing the TV antenna, be careful not to touch the wires.
(5) Safe use of electricity for household appliances
Let one student read the sixth question in the textbook, let another student read the answer to the sixth question and let the third student answer it. What did you learn after learning the sixth question and answer? In order to use electricity safely, the metal shell of household appliances must be grounded. Please go home and check which electrical appliances have metal casings, and try to ground those that are not grounded.
Continue to let one student read the seventh question, and the other student read the answer to the seventh question. Then guide the students to look at the pictures in the textbook 10- 12. Finally, the teacher pointed out that in high buildings, outdoor antennas must be equipped with lightning protection devices.
(6) Two forms of high voltage electric shock
Print out the pictures in the textbook 10- 13 with slides. Ask the students if they have seen this sign. Let the students remember this sign, and then tell the eighth question and answer, let the students know the harm of high pressure.
Let the students look at the ninth question and answer in the textbook. Show the wall chart of figure 10- 14 in the textbook to explain two forms of high-voltage electric shock:
High-voltage arc shock: When the human body is close to the high-voltage charged body to a certain distance, discharge will occur between the high-voltage charged body and the human body. At this time, a current passes through the human body, causing high-voltage arc to get an electric shock.
Step voltage shock: the high-voltage transmission line falls on the ground, and there are voltages at various points on the ground at different distances from the broken line. When people are close to the fracture, the feet are in different positions from the fracture, so there is a voltage (step voltage) between the feet. At this time, the current passes through the human body, causing the step voltage to get an electric shock.
It is emphasized that in order to use electricity safely, don't go near high-voltage charged bodies.
(7) Electric shock first aid
Guide students to read the tenth question and the answer in the textbook. Know some first aid methods for electric shock and fire in life.
3. Summary (teachers and students * * * with summary)
(l) safe voltage value.
(2) Causes of electric shock and four forms of electric shock.
(3) Common sense of safe electricity use.
(4) the method of electric shock first aid.
4. Organize students to discuss the fourth point of "observation, practice and investigation" in the textbook. Q: Classmates, does your home circuit violate the safe use of electricity? Have you found anything that violates the safe use of electricity in school circuits?
Let the students discuss and answer, praise the students who ask questions, and encourage them to find and ask questions. Ask the students to propose solutions to the problems just raised.
