The teaching plan of "Various Bridges" for the big class 1 aims at:
1, know all kinds of bridges, say the name of the bridge, perceive the shape and composition of the bridge and understand the development history of the bridge.
2. By reading children's books, we can get to know all kinds of bridges, initially perceive the architectural structure of bridges and understand the functions of bridges.
3. Be interested in the bridge and actively participate in the discussion of the bridge topic.
Let the children be interested in exploring the bridge.
5. Cultivate mutual comity and learn the ability of division of labor and cooperation through experiments.
Activity preparation:
1, a children's book.
2. Parents lead their children to visit nearby bridges.
Activity flow:
1, guide children to discuss freely and recall the bridge they have seen.
Teacher: Have you ever seen the bridge when you went out with your parents? Where did you meet him? What was the bridge like when you saw it? Children communicate with peers first, and then communicate in groups.
2. Open children's books and guide children to initially perceive and understand various bridges.
Teacher: What kind of bridge is this? Did you tell me what it was called? What shape is it? What material is it made of?
Lead children to observe page by page and feel the bridge with different structural characteristics. Guide children to know wooden bridges, wooden bridges, cable bridges, arch bridges, highway bridges, railway bridges, steel frame bridges, cable-stayed bridges and overpasses.
Introduce famous bridges at home and abroad to children, such as London Bridge, Golden Gate Bridge in America, Jiangyin Yangtze River Bridge in China and Akashi Strait Bridge in Japan.
3. Guide the children to discuss the usage of various bridges.
Teacher: We know there are all kinds of bridges. What do they have in common? Why are some bridges built on roads instead of rivers? Why are some bridges big and long, while others are small?
The children discuss and express their findings and understanding.
The teacher told the history of the bridge.
Teacher: Just now, we learned all kinds of bridges. Our ancient working people used their own ingenuity to design and build various bridges. With the development of science and technology, modern designers and workers have designed and built various modern bridges. What kind of bridge do you like? What kind of bridge do you think is good? Why?
Children observe children's books, broaden their horizons and enrich their experiences.
Activity reflection
Children are limited by life experience and know little about bridges, which affects their creativity. Make more preparations before class, so that children can observe and understand the shape and use of the bridge in their lives, enrich their experience, and let them better disperse their thinking and innovate.

Teaching plan of "Various Bridges" in the big class 41. Design intention:
A few days ago, we went for a spring outing, and the car drove over the viaduct. The children were very excited to say that they were on the bridge, so I asked what bridge it was. Some children say it's a viaduct. On the way, we also met many other bridges, especially the Taihu Bridge and the small wooden bridge in the park. I guided the children to observe these bridges along the way. Suzhou is a water city, and bridges are the most distinctive buildings in our city, so I suggest that children go back and collect all kinds of bridges to find out which ones are there. In view of these circumstances, we decided to introduce children's interest in bridges into our classroom and designated the following activities:
1, know all kinds of bridges and their relationship with people.
2. Understand the different shapes of the bridge, the different building materials used and the various functions of the bridge.
3. Be interested in all kinds of bridges and be able to actively participate in discussion and exploration.
The focus and difficulty of this activity is to understand the different appearance characteristics of the bridge, the different building materials used and the various functions of the bridge.
The preparation of the activity is to better achieve the goal of the activity, so all the activities are selected around the goal of the activity: before the activity begins, build some bridges with the children by building games and visit the activity venue.
CD audio-visual products about various bridges, pictures and models collected by children about bridges, and photos taken during spring outing.
Second, teaching methods and learning methods.
For this activity, children have certain life experience, and as a supporter, author and guide in children's learning, I mainly use situational method to give children a situation, and then through the whole activity, I use the methods of communication, discussion, observation, inspiration and association to let children form their initial impression of the bridge in a relaxed and free environment. When solving the difficulties in activities, I first let my children observe the various shapes of the bridge, and then combined with my own life experience, I extended from the shape of the bridge to the building materials and functions of the bridge. In this process, from the superficial to the deep, from the surface to the inside, let children refine and form new experiences through methods such as perception, memory and association, and let children develop their abilities of observation, perception and generalization in swimming around the lake and opening activities.
Third, the teaching procedure.
I mainly designed three links for this activity. Visiting the model exhibition will arouse children's interest in bridges-guide them to appreciate all kinds of bridges, know the building materials of bridges-know the various functions of bridges, and arouse children's interest and thinking about bridges.
1. Visit the model exhibition of the bridge.
Children line up, just like a spring outing. The teacher beeped to show that he was driving and said to the children, shall we get on the bus and play together? Introducing a game scene can attract children's attention to activities. While driving, guide the children to look at the model and ask what bridge this is. There are Taihu Bridge, Viaduct and Jiuqu Bridge in the model. These models are brought by children and made with teachers, so they know what this bridge is and can fully stimulate the enthusiasm of children to speak.
2. Guide children to appreciate various bridges.
The children are sitting by the bridge. What do they look like? What is it made of? During the spring outing, the children made a good analogy to the Taihu Bridge. Now please tell them again, they will be very active. A good introduction to the following question: What other bridges have you seen? What is it like? What is it made of? Ask the children to talk about it. Teachers show pictures according to children's stories or on computers. The children have collected and observed the bridge, so they have some life experience and have something to say. At the same time, when describing what the bridge is made of, the child with strong ability is required to answer the teacher's questions together, but for the child with poor ability, he can't say these questions together, so remind him accordingly, such as what is he made of? Let the children say what the bridge looks like, but some bridges are very special, such as Huangpu Bridge. Some children may say it looks like a piano, others like a fan, and so on. We should praise and affirm children's bold imagination.
3, understand the main functions of the bridge, print and distribute children's observation interest and thinking about the bridge.
Our bridges have different shapes, some like what, some like what, and some like what. To sum up, some are made of wood, some are poured with cement, some are made of bamboo, and some are made of steel wire. What are these bridges for? Arouse children to think about the role of the bridge. When children talk about the functions of bridges, most people may say that cars can drive, people can walk on bridges, and some bridges can pass trains. The children's answers are very general and there is no accurate classification, so I asked if all bridges can let cars and people walk together. Because of children's classification of bridges, because children have had the experience that only cars can walk on viaducts and only people can walk on footbridges, children will say no as soon as they ask questions. When children know that some bridges can only be crossed and some bridges can only be crossed by cars, they ask why some bridges can only be crossed by cars and some can only be crossed by people. By making children think and discuss, we know that concretizing the function of the bridge can improve our current traffic congestion. Finally, at the end of the activity, the teacher concluded: Our bridge has helped us to improve the traffic conditions and make it easier for us to get in touch with people from different places. Such a beautiful bridge has also beautified our environment. Do you want to design a beautiful bridge? Please tell each child what kind of bridge they want to design.
Four. Promotional activities
Let the children have an imaginary space for the bridge, and then lead the children to draw the bridge themselves. This link can be placed in the manual area of independent activities, and a game of bridge design institute can be specially opened. At the same time, it can also cooperate with the building blocks in the construction area, so that children can build their own bridges. Make children's interest in the bridge continue, further expand their imagination, and organically integrate scientific activities with artistic activities. These are just my thoughts, and I will carry them out and improve them in my future work.
Teaching Plan of "Various Bridges" in Big Class May 1, Design Intention
The "Guidelines for Kindergarten Education" points out that "science education should be closely linked with children's real life, and the objects of scientific inquiry should be the things and phenomena around them." Popular science activities in kindergartens are deeply loved by children, and children can produce valuable popular science education activities for common things around them. Bridge is a common thing in children's life, and it also plays a certain role in life. Moreover, different bridges have different materials and shapes, so children are curious and interested in exploring. Introduce children's interest in bridge into the classroom, let children experience the process of exploring bridge and communicate with friends.
Second, the activity objectives
1. Understand the main materials used in bridge construction in three periods.
2. Can describe the characteristics, building materials and functions of different bridges through observation and comparison.
3. Feel the progress of scientific development by understanding the evolution of bridges.
Third, activities are both important and difficult.
Focus: Understand the function, structure and main materials of the bridge.
Difficulties: Can describe the characteristics, building materials and functions of different bridges.
Fourth, activity preparation
1.PPT courseware (pictures of bridges made of different materials and bridges built in different places).
2. A mystery about this bridge.
Verb (abbreviation of verb) activity process
(1) import
The teacher gave the children a riddle to guess, which aroused their interest and led to the theme.
Teacher: Kid, the teacher told a riddle. Can you guess what it is?
Teacher: It looks like a boat, not a boat. It always stops by the river. Trains and cars can carry things, but they can't sail. Let's guess what it is. (bridge)
Teacher: I believe smart people have guessed. Yes, you guessed it. It's a bridge!
(2) Guide children to recall all kinds of bridges they have seen.
Teacher: Children, we see all kinds of bridges in our life. Have you ever seen a bridge? What bridge have you seen? What is it like? Today, let's get to know all kinds of bridges.
(C) to guide children to understand the structural and functional characteristics of the bridge
(d) Teachers compile and display PPT pictures. Let's look at the first bridge.
(1) suspension bridge
Suspension bridge, also known as suspension bridge, consists of suspension cables, bridge towers, suspenders, anchors, suspenders, stiffening beams and deck systems, which can be seen in scenic spots generally.
(2) single-plank bridge
Simple footbridges, usually made of wood with one side flattened, are placed on cliffs and other places. The most common place is the countryside. Although it is simple to manufacture, it will be injured or even lost if it is not careful. If you want to cross the bridge, you must be accompanied by an adult, otherwise your life will be in danger.
(3) steel bridge
Look at steel bridges and steel bridges, which are mainly made of steel. They have the characteristics of high strength and high rigidity. Most of these bridges can be seen in cities, and some children can cross them when they go to school.
(4) Arch bridge
Arch bridge refers to a bridge with arch as the main load-bearing component in the vertical plane. The arch bridge was built in the late eastern part of Hanzhong with a history of 1800 years. Beautiful appearance, rounded curve and full of movement. Like the Jade Belt Bridge in the Summer Palace in Beijing, it is one kind. There is also Zhao Zhouqiao, which is also a kind of arch bridge.
(4) Overpass
Overpass, also known as "interchange bridge", is a modern bridge built at important traffic intersections in the city. It is layered up and down, and multiple directions do not interfere with each other. The construction cost of this kind of bridge is high, and it is usually only built at the intersection of expressway, urban main road or expressway. Its main function is to make vehicles in all directions pass quickly without being controlled by traffic lights at intersections. The main function of overpass is to avoid multi-directional vehicles interfering with each other at the intersection. Its main feature is that the road plane is separated, or the three-dimensional intersection forms multiple layers.
(5) Wooden bridge
Wooden bridge is a bridge with natural wood as the main building material. Wooden bridge is the earliest form of bridge, which has the characteristics of light weight and high strength. Because the wood is widely distributed, the materials are easy to obtain, and the cutting process does not need any complicated tools. The wooden bridge is the earliest bridge form. Therefore, the processing and connecting structure of each part is simple. But it also has the disadvantages of flammability, easy corrosion, bearing capacity and durability easily affected by wood anisotropy and natural defects. This kind of bridge can only be seen in mountainous landscape areas.
(5) Lianliankan game links
Let the children find pictures of solitary trees, steel bridges, overpasses, arch bridges, suspension bridges and corresponding bridges.
An overview of intransitive verb activities;
With the development of science and technology, in addition to these bridges, there will be more advanced bridges with beautiful appearance. Children can observe more and find more magnificent bridges in peacetime.
