As a faculty member, you often need to prepare lesson plans, which are the basic conditions for ensuring the success of teaching and improving the quality of teaching. Come and refer to the lesson plans you need! The following is a lesson plan for middle class that I carefully compiled: an interesting mirror for your reference. I hope it can help friends in need. Middle class lesson plan: Interesting mirror 1
1. Design intention
There is a large mirror in the kindergarten activity area. Recently, children always like to look in the mirror, and some children also talk about their own homes. For this reason, I organized children to bring mirrors at home to kindergarten and designed "interesting mirrors" to understand the characteristics and uses of mirrors and stimulate children's interest in exploring things.
2. Activity goals
1. Understand mirrors, their characteristics and general uses.
2. Be able to discover the principles of making mirrors through experiments and know the materials for making mirrors.
3. Love scientific exploration activities and be able to boldly talk about your own discoveries.
3. Activity preparation
1. Everyone has a small mirror and a piece of smooth rounded glass that they brought.
2. Various colored papers, plastic sheets, and sludge, each group has a small basket.
IV. Activity Process
1. Invite the children to play with the mirror freely and guide them to discover the characteristics of the mirror.
①Show the mirror and raise the topic
——Children, what is the teacher holding? (Mirror)
——Yes, the children already know it. Then the teacher will ask you to play a game with the mirror. After playing, you will be asked to answer two questions from the teacher. What does the mirror you brought look like? How do you play with it?
②Children are free to play with the mirror: Please be careful not to break the mirror when playing.
③Communicate and discuss the shape and characteristics of mirrors
——Now ask the children to stop and put your mirrors on the table. The teacher wants to ask you to answer the question I just asked. What does the mirror you brought look like? How do you play with it?
Default:
(1) My mirror belongs to Mickey Mouse. The surface of the mirror is very smooth. I played the game of looking in the mirror. (The outside shape of the mirror is different. The mirror surface is smooth and can reflect things and people.)
(2) My mirror is red and the surface of the mirror is cold. I use the mirror to play with the sun. game. (The mirror surface is cool, and the mirror can reflect light)
(3) My mirror has no outer shell, and the back is black. (There is a layer of stuff behind the mirror)
(4) My mirror is square and I broke it (if no children broke the mirror, ask a question - who knows why the teacher just asked you to play Should you be careful when handling the mirror? (It will break or break. Yes, because the mirror will break if you drop it or touch it. It is very fragile)
: Mirrors have different shapes on the outside. But the mirrors inside are all the same. Its surface is smooth and cold, it can reflect things and people, it is fragile, it reflects light, and there is a layer of black stuff behind it.
2. Invite children to explore freely and understand the materials and principles of making mirrors
① Arouse children’s interest and put forward the purpose and requirements of exploration
——We just After playing a game with the mirror, I learned that mirrors are different from other things in many ways. Now the teacher is going to test everyone. What are mirrors made of? (Glass)
——There is glass in our small frame. Children, take it out and try it. Can it show your little face?
——The glass can’t show our people, so what’s going on? (There is a layer of stuff behind it)
——Then what is that layer of black stuff? I would like to invite the children to try to find it.
②Invite children to explore freely: remind children to operate carefully to prevent their hands from being scratched by the glass. Do not pick up broken glass with your hands.
③Communication and discussion
——Have you found it?
Default: I haven’t found it yet, but I think using putty behind the glass can bring out a little bit of the light.
I found it and placed the black paper at the back so I could see it clearly.
：We children have searched carefully, but they can’t be as clear as real mirrors. So what are real mirrors made of? It is made of silver, with a layer of paint on the back, because silver will slowly deteriorate over time. Painting can protect the silver and make the mirror last longer. The current price of silver It was expensive, so people came up with a new thing to replace silver. His name was aluminum.
3. Understand the function of mirrors
——We have just learned so much about mirrors, and now the teacher still wants to test you. Where have you all seen mirrors? Woolen cloth? What are they used for?
Default: at home, you can look in the mirror; in the store, you can try on clothes; in the car, you can use the reflector, etc.
：Mirrors have many functions, they can make us better clean and improve our appearance, they can focus light, they can be used as decorations, they can make transportation more convenient, etc.
4. and Play the game in the sunshine (put in a short game)
Game rules: Ask the children to stand in a place with sunshine. When the teacher is in a place where the sun is not shining, ask the children to use the mirror in their hands. The person who reflects the sun's rays onto the teacher's body the fastest wins. After most people take the photo, they change places and repeat the cycle. After you become proficient, you can ask children to replace it or use any real object on the venue to increase the fun.
——Invite the children to pick up the mirror in their hands and shine the sun on where the teacher is standing. Compare who can move the fastest and make the mirror obey your orders. End the fun freely. "Mirror" teaching activity.
5. End of the activity

2. Middle class lesson plan: Interesting Mirror 2
Activity goals
1. Understand the basic characteristics and uses of mirrors.
2. Know that two mirrors will reflect different numbers of images with different rotation angles.
3. Cultivate the habit of careful observation and interest in exploration.
Preparation for the activity
Several cartoon animal pieces of paper, 30 mirrors, pens
Activity process
1. Discover myself: children Dear children, let me guess a riddle before class starts: "I look at you, you look at me, without me there is no you, without you there is me." The teacher showed the mirror and asked the children to observe its characteristics.
Question: Let’s take a look at what the mirror looks like.
(Mirrors are made of glass, which is smooth, cool, and reflective. The back is coated with a special material called metallic paint, so that objects can be clearly illuminated. Learn about metallic paint with young children)
Question: Why can I see my own appearance.
(Introducing the word "reflection" because light reflects our appearance on the mirror, and the mirror reflects the above image into our eyes). Invite the children to come up and tell the story based on the pictures.
2. The secret behind it.
Question: Children can see their own faces, but can they find a way to see the back of their heads? Provide each child with a mirror to operate on their own.
Question: Can I not see the back of my head with one mirror? Then I will ask two children to cooperate and see if they can see it with two mirrors. Then the teacher asked the children to come up and face the children, and put any picture on the back of their heads so that they could see the pictures behind them using two mirrors.
3. Count.
The teacher first places the two mirrors in the same direction and asks the children to come up and count the number of pens in the mirror. Then rotate a mirror so that it shows 2 images, 3 images, 4 images... countless, and ask the children to come up and observe.
Question: Do you still remember what the teacher did just now and what you discovered. Briefly introduce the reason (repeated reflections between mirrors). Explore in groups.
Activity extension:
