The "egg" theme activity lasted for nearly three weeks. Throughout the entire activity, we were deeply moved by the children's active exploration spirit, and also realized that every child has unlimited development potential. At the same time, in the process of teachers and students' joint construction activities, we have a new understanding of how to correctly grasp the information from children. This is the key to realizing children's independent learning and reflecting the leading role of teachers.

1. The emergence of the theme

One morning, the weather was clear and the sun was shining brightly. We took the children to visit the vegetable market. There were a dazzling array of vegetables in the vegetable market, and the children looked around excitedly. Suddenly, child Liu Congwei excitedly pointed to the stall in front and shouted: "Look, there are many eggs over there!" For a while, the children were attracted by the eggs of different sizes and colors, and started talking about them. "This egg is so big!" "This is a goose egg. I have eaten goose eggs. My mother said that after eating goose eggs, you will grow into an oval face, which is so beautiful." "These eggs are small, what are they? "Where are the eggs?" "These are quail eggs, I've eaten them before." Wang Linghao and Yang Yulei couldn't help but reach out and touch each of the bare eggs. "Be careful, the egg may break." Liu Xiao stopped them and said sensibly.

I listened to the children, and an idea came to my mind: Wouldn’t this be a good opportunity for the children to observe and explore various eggs? So, surrounding the egg seller's stall, the children asked questions one after another. The children's interest in eggs was further aroused, and an "egg" themed activity began.

2. The value of the theme

In the eyes of adults, "egg" seems very simple. However, in the eyes of children, "Egg" is a mysterious world, a mystery, a poem, and an endless story. Young children have a strong interest in eggs, but their knowledge of eggs is only some perceptual experience, and they do not understand the structure and hatching of eggs. Therefore, young children can learn from parents, peers, books, and the Internet through various channels. Gain knowledge about eggs. In addition, in activities such as "understanding the types of eggs", "egg hatching", "doing small experiments about eggs", "tasting egg products", "eggshell making" and other activities, you can not only follow children's interests, but also cultivate children's observation ability and exploration ability. ability, oral expression ability and hands-on operation ability. At the same time, creative ability and independent learning ability are also developed.

3. General objectives of the theme

1. Preliminarily cultivate children's awareness of independent learning, and be able to use various senses to proactively understand the types, structures and hatching of eggs.

2. Able to express in the form of communication, conversation, experiment and manual production.

3. Cultivate children’s observation ability, hands-on operation ability, exploration ability and creative ability; feel happy emotions and experience the joy of success.

4. Implementation of the theme

Activity 1: Types of eggs

There are many varieties and quantities of eggs in the vegetable market, which is a good way for children to understand various eggs. The best place, so the vegetable market became a "classroom". The children gathered around the egg stall, looking at so many eggs of different shapes, sizes, and colors, and talking one after another: "The eggs in the basket here are bigger, and the ones over there are smaller." "What's the color of the eggs?" The same, this is white, this is light yellow, this is orange, and there are flowers. ""These are big goose eggs, the most beautiful ones are oval faces." "These are all quail eggs, I eat them. "I passed." "Teacher, what kind of eggs are there wrapped in paper in the box?" Chen Cheng asked while holding my hand. I shrugged my shoulders and spread my hands, indicating that I didn't know. She was stunned at first, then rolled her eyes, and asked the aunt selling eggs: "Auntie, what kind of eggs are these wrapped in paper?" The aunt was an enthusiastic person, and introduced to the child that they were preserved eggs, and introduced The process of making preserved eggs.

After Chen Cheng’s question and the aunt’s enthusiastic explanation, the children became bolder and started talking to the aunt. Tiantian pointed to a particularly large duck egg and asked: "Auntie, this is a goose egg, why are it put together with a duck egg?" Based on experience, the aunt told the children: "This is a duck egg, a double yolk egg." Tiantian asked: "What? Is it a double yolk egg?" The aunt told the children: "When you open the egg shell, you can see two yolks inside, just like you see twins. If you use such an egg to hatch a duckling, you can hatch two ducklings.

"I promptly praised Tiantian for his careful observation and boldness.

Activity 2. The structure of eggs

The children were particularly interested in double-yolk eggs, so we brought the double-yolk eggs back Went to kindergarten. The children were very curious and eager to open it. I found a transparent glass and cracked two eggs, one was a double yolk egg and the other was a single yolk egg. When the children saw it, Li Ye immediately said excitedly: "I know, there are two yolks in a double-yolk egg. "Why is there water next to the egg yolk?" Diandian asked curiously. Hu Jiali rushed to say: "It's not water, it's egg white. My mother mixes egg white with pearl powder and applies it on her face. It can beautify." Yingying said happily: "I also know that grandma cooked the eggs and gave them to eat. When the eggs are cooked, the egg whites will turn white." ”

Activity 3. Egg hatching

In the past few days, various eggs collected by parents and teachers have been displayed in the area corner, including chicken eggs, duck eggs, goose eggs, quail eggs, Pigeon eggs... From the children's discussions, I found that their focus has turned to the hatching of the eggs. A series of questions followed: Are there babies in every egg? When will it come out? Will the baby inside the egg suffocate to death? How many chicks can escape from an egg? I did not answer these questions directly, but encouraged the children to take the questions home. Find the answer. Then I looked for the VCD "Egg Hatching". The realistic animation showed the whole process of egg hatching. The children were excited to watch and discuss it. I found that each child thought about the problem in his own way. Cai Xubing said: "My aunt works in a duck farm, and I have seen mother ducks sitting on eggs to hatch their ducklings. After a while, Tiantian cried out curiously: "There is a chick inside the eggshell!" I immediately reminded: "Yes, I watch it very carefully every day. Then look at what the egg yolk has become?" "Under the guidance of the question, the children's expressions became more focused and they observed purposefully. Chen Cheng touched Wang Linghao next to him and said, "The egg yolk has turned into a chick's belly. Dongdong gestured with his hands and said, "The egg yolk will become smaller and smaller, and it will become the chicken's belly." "When the children revealed this secret, they couldn't help but clapped their hands and shouted in unison: "The baby chicken is coming out soon! ”

I reminded the children to calm down and look back. The following pictures confirmed the children’s discovery: egg yolks are used to grow internal organs. At this time, the children were waiting for the chickens to hatch, and a voice came out: He came out and asked loudly: "Teacher, why doesn't the chicken come out yet?" "Shh, don't scare the baby chicken." "I said softly to the children. On the screen, the chick was pecking the eggshell bit by bit with its mouth. The activity room was quiet, and the children were watching intently. When they saw the chick was about to peck open the eggshell, , the children said "Come on, come on!" "The ground helped the chick try hard. Finally, the chick's claws hooked the egg shell and kicked outward. The chick broke out of the shell, and the activity room burst into cheers.

Can all the eggs hatch? Where are the chicks? In order to find the correct answer, we looked up relevant information. Now the children know that the eggs we usually eat cannot hatch baby chicks, only eggs laid by the father and mother of the chicken.

Activity 4: Experiments on eggs

Revolving around the theme of "eggs", children have developed an increasingly strong desire to explore, such as how to make eggs stand up? How to distinguish raw eggs from cooked eggs? Do eggs sink or float in water? How long does it take to cook an egg?

Let’s sort out the questions raised by the children. Sufficient materials are provided in the exploration area, such as raw and cooked eggs, transparent beakers, salt, warm water and building blocks, etc., allowing children to do experiments of their own interest. Their desire to explore is satisfied in the exploration area, and they discover the Secret: Shake and listen, you can tell whether it is a raw egg or a cooked egg; adding salt to warm water can make raw eggs float, etc.

Activity 5. Food made from eggs< /p>

The children’s enthusiasm for studying eggs still continues, but they have turned to food made from eggs. The children know a lot, and they named 15 kinds of egg foods, including preserved eggs, cakes, and egg rolls. , egg pine... The naughty Hu Zhirong suggested that he want to taste various eggs, so there was an egg food tasting party. The children brought egg products made or bought together with their parents, and they were delicious. It filled the entire activity room. The children were enjoying the relaxing music and chatting softly in groups, with smiles on their faces and immersed in joy.

Activity 6: Eggshell making

During the egg product tasting party, the children and I collected some broken eggshells and contacted the canteen to collect some. Only a small eggshell was broken open. Various eggshells with holes. These beautiful eggshells are placed in the art area by category. The unusual eggshells arouse children's desire to create. Yang Jiajian used it to make a non-falling doll. Xiaoxiao found crepe paper and double-sided tape to dress up the egg baby. Cheng Qian directly painted on the eggshell with watercolor pens, and several children glued plasticine to the eggshell to make it. The bunny, the bear, the piglet and the kitten also played the game of "Little Can Treat", which they wrote and performed themselves. The children and I used the corner of the activity room to arrange an "egg doll" column. Many children joined in and their works became more and more, making the activity room more and more beautiful. Healthy and nutritious egg mid-school lesson plan 5
