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. Teach children to be brave children.
Know how to save yourself in a dangerous situation.
Activity preparation:
1, a children's book.
2, a wire, a socket, a sign of "electricity".
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 discussion:
(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 sign of "electricity" to let children know that they should be vigilant and pay attention to safety when they see the sign of "electricity".
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?
Let children know simple common sense of safe use of electricity and learn to protect themselves. Before the activity, show the children pictures of various household appliances to stimulate their interest. In terms of safe use of electricity, please watch the right and wrong video of using electrical appliances again to understand the importance of safe use of electricity.
Activity reflection:
Scientific activities focus on stimulating children's cognitive interest and exploration desire. In this activity, I freely explored the names and functions of household appliances by letting the children discuss in groups. The children are very interested and have a heated discussion. Many children can express their thoughts and results according to their existing experience. Finally, children are inspired to identify household appliances in the form of records. Many children can tell whether it is a household appliance or not. This activity has achieved good teaching results.
