Activity flow:
(1) Guide children to observe the roots of plants.
1. Children observe the roots of plants by themselves.
What do you see on the table, children? (Onions, vegetables)

teaching process
First, the roots of plants I have seen.
1. The children will show the collected pictures one by one and introduce them to everyone.
2. Children exchange their findings with each other and enrich their understanding of roots.
Second, what is the root like?
1, let the children guess what the roots of natural angle plants are like.
Children pull out the roots of all kinds of plants from the corners of nature. Observation: What are their roots? What are these like? What's the difference between them?

5. Let the children taste the cooked carrots and sweet potatoes.
6. Teachers and children introduce the relationship between tree roots and human beings according to their own life experiences.
7. Guide children to observe the natural angle and find different forms of plant roots.
Activity reflection:
Although children often see roots, such as planting horns in kindergartens, they will also come into contact with some roots when shopping and picking vegetables with their mothers. However, due to the lack of guidance, these roots are not remembered in their eyes, and even some children don't know that the radishes and sweet potatoes we eat are the roots of plants. Therefore, it is necessary for children to form a correct understanding of roots, understand the types, characteristics and uses of roots, and stimulate children's desire to explore plants.
One of my guiding ideas in designing this activity is to give children more opportunities to operate and explore. So I arranged many attempts in the activity. The first time is mainly to explore the external feeling and form of roots, so that children can get a feeling by looking, touching and comparing. The second attempt is to classify the roots. In the third part of the activity, I guide children to play the role of roots and experience the role of roots in the process of growth. This has injected new vitality into the game activities. During the performance, the children not only learned about the growth of roots, but also expressed different forms of roots with body language.
Judging from the effect of the activity, the children are still very interested in this activity. During the activity, they spoke actively and spoke out their ideas boldly. Be able to observe the roots of plants carefully and find out the differences. The goal was accomplished well. However, there are some shortcomings in this activity. Because there are many children, the activities always feel that children's clubs are chaotic, so the time and depth for children to participate in operational exploration activities are slightly insufficient.

Children, the plants we just observed have been unearthed for a long time. We have to replant them in the soil quickly, or what will happen to them? Ok, take our plants and say goodbye to the visiting teacher.
Encyclopedia: Roots are vegetative organs of plants, usually located below the surface, which are responsible for absorbing water and dissolving inorganic salts in soil, and have the functions of supporting, reproducing and storing synthetic organic matter.
Root's Secret Classroom Teaching Plan 4 I. Design Intention:
Roots are common things in children's lives. You can see the roots of all kinds of vegetables in the plantation of kindergarten, when you visit the food market with your mother and grandmother, and when you help your mother and grandmother pick vegetables. However, this "seeing" is the child's unintentional attention. Through this activity, we raised children's unintentional attention to the level of intentional attention, which not only enriched their knowledge, but also stimulated their interest in exploration.
In the activity, we integrate children's self-management into teaching, and we can see the shadow of children's self-management from their first exploration to their second exploration. Especially the children's second exploration, from their self-combination, group selection, division of labor, candidates for answering questions and so on. The teacher is just a bystander, allowing children to fully and freely develop their self-management ability.
Second, the activity objectives:
1, observing and comparing the different forms of roots, we know that the roots of plants grow in soil.
2. Be able to express boldly in the activity and experience the fun of exploring the roots of different plants.
3. Pay attention to listening to and respecting peers' speeches in communication activities.
4. Experience the sense of accomplishment in solving problems.
Third, the activity preparation:
1, root, blackboard, basket.
2. Plantations in the park. Children's questionnaire "list three" (graphic combination) 4. Activity flow:
(1) Import 1 to show the roots and let children touch and feel the external characteristics of the roots.
Do you know any other plants with roots?
3. The teacher concluded that most plants have roots.
(2) The first exploration 1, children began to look for the roots of vegetables (1) Today, we came to the plantation. Do you know what vegetables we have on the plantation?
(2) You are great. Let me test you: Please find out where the vegetables are and where their roots are. Please pull it out and see who moves fastest.
2. Assembly Q: Where are the roots of vegetables? Where did you find the roots of vegetables?
2. Summary: It turns out that Roots like to live in soil.
(3) The second exploration 1. Please tell me what the roots of vegetables look like.
2. Summary: The roots of green vegetables are straight, and there are many small Mao Mao beside them.
There are so many plants in our plantation. Are the roots of each plant the same as those of vegetables? Do you want to explore the secret of root-seeking together?
Next, I will give you a task: please look for, pull out and look at the roots of other plants in the garden. Requirements:
(1) Free combination, three people as a group, each group chooses a group leader, and the selected group leader gets the basket from the teacher. (2) Only one plant can be pulled out, and when you pull it out, record it (show the recording paper). (3) When you hear the tambourine, please sit together in groups.
5. Collection: Children introduce their own records in groups (comment on the methods and forms of children's records) 6. Children observe the roots of their own vegetables.
Question: What plants did you find? What are their roots? (One representative of each group speaks and answers, and other members add) 7. Classify according to the characteristics of different roots observed by children.
Summary: Today, we all discovered the secret of roots. He has a nice name for taproots like spinach and vegetables, which is called taproot system. Like the root of leek and garlic, like grandpa's beard, it is called fibrous root system. Roots as thick and big as radishes are called abnormal heels.
We just discovered the secret of the root. Do you know what roots are for? Go home and check the information. We'll discuss it next time.
Fourth, the end of the event:
The teacher summed up the children's performance today, praised and encouraged the children to show positive children in the activities. Let children feel the happiness brought by scientific exploration activities while planting activities. At the same time, teachers should take care of the children who are quiet in the activities, so that they can be happy at the end of the activities, thus cultivating their interest in scientific activities.
