Travel teaching plan for seeds of scientific activities in large classes 1 activity objectives:
1, get a preliminary understanding of the spread modes of several common seeds, and know the relationship between the external forms of seeds and their spread modes.
2. Seeds can be classified according to their modes of transmission.
3. Stimulate children's interest in scientific exploration.
Activity preparation:
Seeds of various plants, ppt
Activity process:
First, the import part:
1 Teacher: Have you ever traveled, children? Who took you there? What means of transportation are used? (car, ship, plane, self-walking)
2. Summary: Our children travel by car, train, ship, plane, or on their own.
Second, play the courseware "Seed Travel" to guide children to understand the four modes of seed transmission and the relationship between the modes of transmission and the shape.
1, Today, some baby seeds of plants happened to come to our class when they went out for a trip. Do you want to know them, children?
(Show pictures of dandelion, Xanthium sibiricum, pod, coconut, etc.)
Teacher: These seed babies have grown up and matured. They are happy to travel without their mothers, but they have no hands or feet, and they don't have cars, ships or planes. How did their mothers send these seed babies to travel? (Ask children to guess)
2. How do they travel? Guess, children. You can discuss with the children around you. (Children discuss in groups)
3. The teacher plays the courseware "Travel of Seeds".
4. Why do they choose this way of travel?
5, teachers and children together to summarize:
Dandelion is light and fluffy, so it can travel with the help of wind, just like flying. (Performing dandelion flight)
Xanthium sibiricum can be hung on people and animals, and travel with the help of people and animals' activities, just like taking a car; (Performing Xanthium by car)
Coconut can float on the water like a boat, so it can travel with the help of water, just like taking a ship; (Performing Coconut Rowing)
Beans in the sun can travel by their own elasticity, just like we walk by ourselves. (Show the beans walking by themselves)
Teacher's summary: seed travel is also called seed spread. Wherever the seeds travel, the plant will spread.
Third, the game: classified according to the way of seed travel:
Poplar, burdock, impatiens, lotus.
Teacher: How are these seeds spread? Can you classify them?
Summary: The way of seed travel is really special. You also know which seeds are spread by these ways, so you can share them with you.
The travel lesson plan of the seeds of scientific activities in large classes 2 Plants are the most common in children's daily life. They are close to life and are most interested in exploring the mysteries of plants. In the wonderful plant kingdom, there are many mysteries, among which seed transmission is one of them.
Activity objectives:
1, preliminary understanding of different modes of seed transmission.
2. Have an interest in exploring plant seeds.
Activity preparation:
1, multimedia courseware: seed travel
2. Seed Travel Pairing Map
Activity process:
I. Activity Import
1, Teacher: Have you all traveled? How did you travel?
Teacher: Today, Teacher Fan invited some good friends. They also want to travel. Would you like to help them?
3. Show PPT courseware: Look, who's here?
4. Teacher: Do you know them? Who can tell me what their names are? (Dandelion, Xanthium sibiricum, Lotus Seed)
Induction and ascension: dandelion, lotus seed and xanthium sibiricum are all seeds of plants.
Second, understand the different modes of seed transmission
1, Teacher: Are all these seeds the same? What are the differences between them?
Induction and promotion: These seeds are different in size, color and shape, some are hairy, some are slippery, some are hooked and have thorns.
2. Teacher: These little seeds can't wait to start their own journey. They will go far away, get into the soil, absorb the sunshine and rain, land, take root and sprout. However, small seeds have no hands or feet. How can they start their own journey?
Follow-up: Are there any ways to help seeds spread in all directions?
3, with the help of multimedia courseware, help children understand the spread of dandelion, lotus, xanthium and other plants.
Dandelion travel
(1) Teacher: Hey, who is talking?
Self-report of Dandelion: I am a dandelion seed with a fluffy little flower. The breeze blew gently and I left my dear mother. Fly, fly, wherever I fly, my home is.
Teacher: Ah, it's the seed of dandelion. Do you hear what it says clearly?
(2) Ask: Can the wind really help dandelion to travel? Let's take a look together. (playing flash)
(3) Ask: Why do dandelion seeds travel with the wind?
Induction and promotion: Because dandelion's seeds are light and fluffy, like a parachute, dandelion relies on wind to help it travel, and wind energy helps dandelion spread its seeds.
☆ Lotus seed travel
(1) Teacher: Who can help Lotus Seed to travel?
(2) Teacher: Listen, what is this noise? (Playing the sound of running water)
Follow-up: Why do lotus seeds travel with the current?
Induction and promotion: It turns out that the lotus can float on the water like a boat, and the lotus seed falls into the water and goes to settle down elsewhere along the current. The lotus seed travels by water, and water can help the lotus seed spread its seeds.
☆ Xanthium travel
(1) Teacher: Who will help Xanthium sibiricum travel? (playing flash)
(2) Ask: Why can small animals help Xanthium sibiricum to travel?
Induction and promotion: Xanthium sibiricum is covered with thorns, which are easy to get on animals and people. Animals and people take it wherever they go, so both animals and people can help Xanthium sibiricum travel.
☆ impatiens seed travel
(1) Teacher: The nature around us is very interesting. It turns out that many seeds are helped to travel by their good friends. There is another kind of seed that can travel without the help of good friends. Do you want to know who it is?
(2) Teacher: Look, it is the seed of Impatiens balsamina. When the seed of Impatiens balsamina matures, the shell cracks and the seed jumps elsewhere to germinate. (Playing video)
Induction and promotion: Impatiens rely on their own seeds to ripen, and their shells crack, and they pop themselves out to travel through their own elasticity. There are many plants that spread by themselves, such as our common soybeans, red beans and mung beans.
4. Teacher: Do you know which plants' seeds travel by these methods? (Playing video)
Induction and promotion: Now we know that seeds spread in many ways, some by wind, some by water, some by people and animals, and some by their own ejection power.
Third, the operation pairing connection diagram
1, Teacher: Today, Teacher Fan is going to test you. Please help these seeds find good friends who can take him on a trip.
2. Verification: Look, are you all right?
3. Teacher: your is really capable. Let's praise ourselves together. Great! I'm great!
Induction and promotion: Plants in nature are wonderful. It turns out that so many seeds are spread by their good friends, and of course some things are spread by their own strength. There are still many mysteries of plants around us that have not been discovered. They are all waiting for our children to observe and discover with their hearts.
Travel teaching plan for seeds of scientific activities in large classes 3 ● Activity objectives
1. On the basis of understanding all kinds of seeds, we can understand several modes of transmission of seeds and make simple classification.
2. Be able to express your opinions boldly and develop observation and analysis skills.
3. Germinate the interest in exploring the mystery of plant seeds.
● Activity preparation
1. Ask children to collect all kinds of seeds and take them to the kindergarten to arrange a "seed exhibition".
2. There are a number of seeds for each group of children to operate, background maps of transmission modes, and a number of seed specimens, and the courseware "Travel of Seeds".
3. Parents and children are invited to collect relevant knowledge of seed transmission mode together to enrich perceptual experience. Conditional parents can take their children for hiking activities and observe plants in nature.
● Activity suggestion
1. Guide children to visit the seed exhibition and know the characteristics of various seeds.
(1) Teachers ask related questions, and children are free to observe with questions. Take a look at what seeds they are What does it look like? What's the difference between these seeds? Guide children to discover the shape characteristics of different seeds.
(2) Ask children to name the seeds they know, and know several special seeds (dandelion, lotus, xanthium, etc.).
For the seeds that children don't know, please ask other children to supplement each other. Without explanation, the teacher can ask: What are the differences between so many seeds? Guide children to understand the differences in seed size, color and shape in mutual learning.
(3) Children discuss with each other: What are the uses of these seeds? Make children simply understand that seeds can be propagated and eaten.
2. Play the courseware "Seed Travel" to guide children to understand the way of seed transmission.
(1) Understand the wind propagation of seeds.
① Watch the courseware and guide the children to discuss: Who helped Dandelion's children travel? Why does the wind blow it to travel? The teacher took out the real thing, guided the children to observe and analyze, and asked the children to try it, so as to further perceive the "light floating" characteristics of dandelion seeds.
Ask children to think: dandelion seeds have flown to a new place. What will happen when spring comes? Guide children to understand the growth process of plant seeds "germination-growth-flowering-fruit-reproduction".
3 Guide children to expand their thinking: What seeds can the wind help to travel? Why?
Enrich children's knowledge: catkin, poplar and other seeds are very light and are blown around by the wind.
So they also travel with the help of the wind.
(2) Discuss other modes of seed transmission (running water, animal fur, bird droppings, human sowing, etc.) by combining objects with courseware.
Show bitter fleabane bitter fleabane, cocklebur, cherry, pea, etc. in the courseware. Discuss: How do their seeds travel? Why? What other seeds travel in the same way as them?
Ask children to think: What seeds can humans help to travel? Let children know that the seeds of crops are mostly traveled with the help of human beings.
Summary: Lotus can float on water like a boat, and its seeds can be spread by water. Xanthium sibiricum has thorns, which can stick to animal fur to travel; Some hard seeds are not digested after being eaten by birds, but can be discharged with feces. They travel with birds. After some seeds mature, the skin of the fruit cracks, and the seeds pop themselves out to travel through their own elasticity.
3. Play the game "Help the seeds to travel" to classify the modes of transmission.
(1) The teacher shows the seed specimen on the blackboard and asks the children to choose their favorite seed.
(2) Guide children to tell what seed it is and how it spreads, and put it in the background map of the corresponding mode of communication.
(3) Check with the children whether it is put right. If it is not right, explain why. Further consolidate children's cognition of seed transmission mode.
Travel teaching plan for seeds of scientific activities in large classes 4 Activity objectives
1, stimulate children's interest in exploring the mystery of plant seeds through activities.
2. Guide children to understand several modes of seed transmission and make a simple classification on the basis of understanding various seeds.
3. Encourage children to speak out their opinions boldly and develop their observation and analysis abilities.
Activities to prepare
Collect all kinds of seeds with children and arrange seed exhibitions; Background map of transmission mode and some seed specimens; Courseware: Travel of Seeds
Key and difficult points
Focus on guiding children to understand the way of seed transmission; The difficulty is to understand "why do these seeds travel in this way?"
Activity process
First, guide children to visit the seed exhibition and know the characteristics of various seeds.
1, children can observe all kinds of seeds freely. Requirements: Take a look at what seeds they are. What does it look like? What is the difference?
2. Ask children to name the seeds they know and know several special seeds (dandelion, lotus, xanthium, etc.).
3. Guide children to analyze the characteristics of seeds together: Are these seeds the same? What are the differences? (Understand the differences in seed size, color, shape, etc.)
4. Simply understand that seeds can be used for reproduction and eating: What are the uses of these seeds?
5. Discussion: These seeds are going to travel, how can they go?
Second, guide children to understand the way of seed transmission through the courseware "Seed Travel Notes".
1, understand the wind propagation of seeds:
(1) Dandelion's seed wants to travel. Do you know how to get there?
(2) Discuss after watching the courseware: Who helped Dandelion's children to travel? Why does the wind blow it to travel? (Observe and analyze the characteristics of dandelion seed "light floating")
(3) What seeds can the wind help to travel? Why?
2. Discuss other ways of spreading seeds (water, animals, bird droppings, etc.) by combining objects with courseware: Show lotus, cocklebur, cherry, peas, etc. in the courseware, and discuss: How do their seeds travel? Why? What other seeds travel in the same way as them? Through observation and discussion, we know that lotus can float on water like a boat, and its seeds can be spread by water; Xanthium sibiricum has thorns, which can stick to animal fur to travel; Some hard seeds are not digested after being eaten by birds and can be discharged with feces; After some seeds mature, the skin of the fruit cracks, and the seeds pop themselves out to travel through their own elasticity. )
3. Summarize several modes of seed transmission with children, and know that many seeds are spread by human beings.
Third, through the game "Help the seeds to travel", classify the modes of seed transmission. Ask children to choose their favorite seeds, say what seeds they are and how to spread them, and put them in the background map of the corresponding mode of transmission.
End of activity
Carry out the activity of "I take seeds to travel", let children choose seeds to take home or plant in kindergarten, and experience the fun of helping seeds spread.
Travel teaching plan for seeds of scientific activities in large classes 5 activity objectives
1.Understand how seeds spread.
2. Know the source of seeds.
3. Explore and discover the diversity and characteristics in life.
4. Experience the obvious seasonal characteristics.
5. Willing to try boldly and share your experience with your peers.
Activities to prepare
1.Pictures of Taraxacum mongolicum, Xanthium sibiricum, soybean vine, coconut tree and citrus tree; Pictures of dandelion, Xanthium sibiricum, soybean, coconut and citrus.
2. Teaching wall chart.
Activity process
1.Know the source of the seeds.
Teacher: Do you know what these are?
Show pictures of dandelion grass, Xanthium sibiricum, soybean vine, coconut tree and citrus tree in turn.
Guide children to look at the pictures and answer.
Teacher: Do you know what their seed babies are? What do they all look like?
Guide children to answer boldly.
Show pictures of dandelion, Xanthium sibiricum, soybean, coconut and citrus, and guide children to look at the pictures and recognize things.
Teacher: Do you want to know how the seed babies of Taraxacum mongolicum, Xanthium sibiricum, soybean vine, coconut tree and citrus tree were born?
Please ask the children to guess first, and then the teacher will give common sense.
2. Understand how seeds spread.
Teacher: It's autumn, and the seed babies grow up slowly. They all want to leave their mother and travel to other places, but they have no hands and feet, so they can't walk by themselves. This is very difficult for the seed babies, but they are all smart and have come up with a good idea. Guess what good idea they have come up with?
Teachers guide children to use their imagination and tell them one by one.
Teacher: The children have come up with many good and wonderful ideas. If children see their babies in the future, will you tell them our good ideas? Today, the teacher brought a beautiful picture, which shows how the seed babies travel. Please look at the picture carefully and tell the teacher how they travel respectively.
Show the teaching wall chart and guide the children to observe the pictures carefully and then answer the questions.
Mode of seed transmission: dandelion seeds are transmitted by wind; Xanthium sibiricum hangs on the fur of lamb and spreads; When the soybean is ripe, the seeds jump out of the pod; Coconut falls into the sea when it matures; Citrus will be eaten by birds, and seeds will be excreted through excrement.
Activity reflection
Plants are the most common in children's daily life. Being close to life and exploring the mystery of plants are the most interesting for children. In the wonderful plant kingdom, there are many mysteries, among which the spread of seeds is one. In children's knowledge and experience, the spread of seeds is only a perceptual and vague memory. In daily life, we often see such phenomena: catkins flying all over the sky, dandelions flying in the wind, all of which are experienced and touched by children, but there is no clear concept: in fact, these phenomena are plants spreading seeds. The purpose of this activity is to know and understand the seeds of plants and their modes of transmission, construct children's knowledge structure and expand their horizons.
The travel teaching plan of the seeds of scientific activities in large classes 6 Activity background:
When autumn comes, the seeds of all kinds of plants and crops are ripe. Children always come to you with all kinds of seeds and ask you cheerfully, "Teacher, what kind of seeds is this?" Why did it fall to the ground alone? " Seeing that they are so curious about seeds, our big team has launched an activity process about seed dissemination.
Activity objectives:
1, get a preliminary understanding of several ways of seed transmission, and perceive the interesting and close relationship between natural things.
2. Take an active part in observing and exploring the mode of seed transmission and have a strong thirst for knowledge.
3. Be willing to discuss and share what you know with your partner.
4. Willing to try boldly and share your experience with your peers.
5. Stimulate children's interest in scientific activities.
Important and difficult points of activities:
Children can initially understand several common modes of seed transmission.
Activity preparation:
1, pictures of various seed trips collected by children.
2, all kinds of objects: Xanthium sibiricum, Impatiens balsamina, dandelion.
3. Courseware for seed travel.
Teaching strategies:
Collective communication, individual narration, group discussion, group experiment, and summary.
Activity process:
First, the teacher is led by the story (for the story, see "Little Girl with a Cotton Basket" on page 57 of the guide book for teachers in large classes)
Teacher: Who is the story about? What good ways do they use to travel? What other plants do you know how to travel? (Summary: This link is to arouse children's interest in the spread of seeds from an interesting story, so as to introduce several ways of spreading seeds in the activity, and make children mentally prepared. Next, we will discuss the topic of seed spread, so that we can enter the activity more easily. )
Second, children look at pictures and communicate.
Teacher: A few days ago, you all brought a lot of pictures and materials about plant travel. Now I will send them to you to have a look and communicate with my companions. Explain to children what "communication" means (from one place to another)
Teacher: Please tell us what plants you all know about their modes of transmission.
Young: Impatiens were exposed to the sun and exploded by themselves.
Teacher: This mode of transmission is called elastic transmission. Pods are also spread in this way. Let's take a look at how they spread.
(The teacher takes out a seed of impatiens and demonstrates it. If the materials are sufficient, you can send one to each child and let them try it. )
Teacher: Let's watch a short film to see the whole process of elastic propagation. (watch the short film. )
(Summary: Teachers use all kinds of pictures collected by children to let them observe and understand the magical transmission route of seeds, and let some children who have gone home for investigation try to tell them and pass on their knowledge to other children. In addition, we also searched several short films about seed transmission for children to watch, which is more intuitive, vivid and dynamic. )
Third, children use physical objects to understand the mode of transmission.
Teacher: Besides elastic transmission, what other modes of transmission do you know?
Young: Dandelion is spread by the wind.
The teacher took out the real thing and showed it to the children. Let them observe the spread of dandelion. Each child holds a dandelion in his hand, blows the dandelion seeds with his own mouth and feels the spread of the wind personally. (Animal transmission, hydraulic transmission, the process is the same as above)
Teacher's Summary Today, we learned a lot about the way plants spread, some of which are spread by the wind. We call it wind spread, such as dandelion.
Some are spread by elasticity, which we call elastic spread or self-spread, such as impatiens and pods.
Some are spread by water, which we call hydraulic transmission, such as water lilies and coconuts.
Others are spread by animals, such as Xanthium sibiricum and Solanum nigrum.
Activity reflection:
After understanding the shortcomings of the first activity, we added a lot of physical objects and video clips in the second activity, so that children can understand these physical objects more intuitively and touch, observe and discover them with their own hands. If the teacher only provides pictures in the activity, it will not interest the children, and the activity will not be carried out in depth. In the second activity, the children not only listened to the teachers and peers' introduction of the ways of spreading seeds, but also tried them themselves, and saw with their own eyes that their interest in different ways of spreading increased greatly. Many children also wanted to know the relevant knowledge after the activity.
