Teaching Plan of "Evergreen Trees and Deciduous Trees" in Large Class Science 1 Activity Target:
1, understand the basic characteristics of evergreen trees and deciduous trees, and preliminarily know their differences. (key)
2. Through observation and comparison, we can identify several common deciduous trees and evergreen trees. (Key points and difficulties)
3. Experience the fun of inquiry activities and be willing to express boldly in front of the group. Difficulty: Why do some trees shed leaves and some trees don't?
4. Pay attention to listening to and respecting peers' speeches in communication activities.
5. Let children learn the initial recording method.
Key breakthrough strategy:
1, form combing (flip method)
2, game consolidation (I'll test you)
3. Operating experience
Difficulty breakthrough strategy:
1, three multimedia courseware are progressive layer by layer. Test You —— Two Common Feeling Phenomena of Appreciating Trees
2, two pictures, intuitive (waxy properties-sealed with plastic paper)
Process:
Find the problem (small question mark)-solve the problem, observe and compare-improve in time, and summarize the knowledge points of each link in time-regression problem (small question mark)
Process:
First, the small question mark leads to the topic:
Teacher: When autumn comes, many changes will happen to all kinds of trees. Do you have any questions about trees? (The teacher summed up the children's answers and recorded them in the form of pictures and texts, mainly falling leaves and discoloration)
Second, know evergreen trees and deciduous trees.
1, Teacher: Study the first question first. About …, I have prepared two leaves for you, plane leaves and mountain tea. Please compare, look, touch and take a photo under the light to see the difference.
2, children's operation, comparison (children sit in a semicircle and compare in a chair)
3, collective communication, teacher records (* * * six o' clock)
Color, surface size, hardness, thickness, evergreen trees (painted leaves)
Deciduous trees (painting leaves)
According to the children's answers, the teacher shows the word cards and records.
Glossy-like a mirror
Summary: Trees that are green all year round are called evergreen trees, and trees that shed leaves in autumn, such as buttonwood, are called deciduous trees.
Third, test you (review and consolidate)
Show PPT, "This leaf is green. What tree could it be? " Let the children have a look first, then guess what tree it is, and then show the answer. ***5 leaves, green, yellowish green, thick, soft and rough.
Fourth, children's operation
1, as the teacher said, you should know the pendant first. The two strings are deciduous trees and evergreen trees, each with a bowl of leaves, four kinds of leaves, two deciduous trees and two evergreen trees.
2. Show two blackboards with two lines of hooks, and let the children hang the pendants on the corresponding blackboards after operation.
Verb (short for verb) communication
1, the child checks right and wrong, and then corrects the dislocation, such as pine needles, and the leaves are sharp and hard.
2. Look at PPT pictures and enjoy some common deciduous trees and evergreen trees. (Deciduous trees: persimmon, maple, willow; Evergreen trees: Magnolia grandiflora, osmanthus trees, pine trees)
Teacher: What other deciduous trees and evergreen trees have you seen?
3. Teacher: Why do some trees lose their leaves in autumn?
Let the children guess first.
Play the courseware and introduce the scientific principles.
Question: Did you hear clearly? Why do leaves fall? The leaves are large and have pores, from which water is discharged. Evergreen trees have a bright layer of wax on their surfaces, which can protect water from evaporation.
6. Extended activities: Does the evergreen tree not shed its leaves all year round? Return to the exhibition board with a small question mark, and let the children study with these questions next time. )
Teaching reflection
In this activity, the teaching effect is very good, because these plants are often seen in children's daily life and children are no strangers. Activities give full play to children's initiative, so that children can get answers while doing things, using their brains, comparing, observing and analyzing. Intuitive and concrete teaching methods conform to the characteristics of children's physical and mental development. They are very interested in activities. They play in middle schools and schools, and games make them learn actively and happily, so that children can fully feel it. This class is pleasant and positive from beginning to end, with high interest in learning, which cultivates children's expressive ability and provides a premise for their future creation.
Teaching plan of "Evergreen Trees and Deciduous Trees" in science class 2 teaching material analysis
The seasons are changing, and the surrounding trees are also changing quietly. The leaves of deciduous trees are thin and big. In order to reduce water evaporation, they turn from green to yellow and red, wither gradually and fall with the wind. Evergreen leaves are thick and thin, and there is a layer of wax on the surface to lock water, so they are evergreen all year round.
moving target
1. Understand the main characteristics of evergreen trees and deciduous trees, and distinguish deciduous trees from evergreen trees.
2. Through observation and touch, we can find and preliminarily summarize the difference between evergreen leaves and fallen leaves.
3. Be interested in the characteristics and changes of trees and know how to care for them.
Activities to be prepared
1. Before the activity, take the children to observe the trees in the kindergarten and take photos, and observe and collect the leaves of various deciduous trees and evergreen trees.
2. Activity background charts and pictures, "Children's learning materials"-"How beautiful autumn is".
Activity suggestion
1. Let the children look at the photos of trees and discuss the difference between deciduous trees and evergreen trees.
Question: Do you know these trees? Autumn has come, what has happened to their leaves?
Summary: When autumn comes, the leaves of some trees will turn yellow, red, dry and fall from the trees. These trees are called deciduous trees. The leaves of some trees are green all year round. These trees are called evergreen trees.
2. The children observed the collected leaves in groups and found the difference between deciduous leaves and evergreen leaves.
(1) Put the collected leaves in two baskets according to deciduous trees and evergreen trees to guide children to choose and compare.
Question: Take a look. What's the difference between the shape, size and thickness of leaves? Feel it. What's the difference on the surface of leaves?
(2) Summary: The leaves of deciduous trees are relatively large, thin and soft, yellowish in color and rough to the touch. The leaves of evergreen trees are thin and small, thick and hard, mostly dark green, and feel smooth.
3. Analyze and judge several common trees (deciduous trees or evergreen trees) according to how beautiful autumn is. Please observe all kinds of trees and their leaves on page 4 15 of How Beautiful Autumn is, analyze and judge with experience and pictures, and record them in the chart to encourage children to tell the basis.
Activity expansion
Encourage children to explore and record the reasons why deciduous trees and evergreen trees do not fall, and guide children to share them in popular science areas.
Teaching Plan 3 of "Evergreen Trees and Deciduous Trees" in Large Class Science Activity Objectives
1. Understand the concepts of evergreen trees and deciduous trees.
2, can distinguish between evergreen trees and deciduous trees.
I would like to share my findings with you.
Activities to be prepared
1, character cards: trees, evergreen trees, deciduous trees.
2. Photo: Four pictures of willow and pine trees in spring, summer, autumn and winter, a scientific reference book, and one deciduous evergreen tree.
Activity process
First of all, say trees
1. Show me the word card (Chinese character: tree): Do you know this word?
Today, let's talk about trees.
2. Where have you seen trees?
Summary: There will be trees on both sides of roads, parks, communities, rivers and homes. Yes, there are trees everywhere in our life.
3. What trees do you know?
Summary: You know so many trees. I also brought some trees today. Take a look. what kind of tree is it?
Second, understand the concepts of evergreen trees and deciduous trees
1. Show me the willows of the four seasons: Do you know this tree?
This is a tree that grows in different seasons. Please have a look. In which season do they grow and why?
The teacher refines the content according to the children's answers.
Summary: A tree like willow, whose leaves germinate in spring and lose all their leaves in winter, is called a deciduous tree. (Show pictures and deciduous cards)
4. Show me the pine tree: Look, does this tree change all the year round? Why?
Summary: Like pine trees, trees that grow new leaves, drop old leaves and are evergreen all the year round are called evergreen trees. (Xiuzi Card: Evergreen Tree)
Third, distinguish the remarkable characteristics of evergreen trees and deciduous trees.
1. Are deciduous trees the same as evergreen trees?
I have prepared two kinds of leaves here. Please take a look and feel it. What's the difference between these two leaves?
3. Children observe with leaves.
4. Summary: Evergreen trees have thick leaves and smooth surfaces, because there is a layer of wax on them, while deciduous trees have thin leaves and rough surfaces.
5. Show two trunks and ask the children to classify the leaves according to deciduous trees and evergreen trees.
6. Correct the wrong choice and emphasize the difference between deciduous trees and evergreen trees.
Teaching plan 4 of the scientific activity "Evergreen Trees and Deciduous Trees" in large class aims at:
1, willing to explore different trees, can initially distinguish between evergreen trees and deciduous trees.
2. Feel the joy of picking up fallen leaves and stepping on them.
Activity preparation:
Choose a place with evergreen trees and deciduous trees.
Activity flow:
1, it's getting cold, let's go and see what will happen!
2. Look for deciduous trees, talk about the names of trees and observe the characteristics of leaves. We know that some trees will turn yellow and red in autumn and winter, then fall down and wait until the next spring to grow new leaves. This kind of tree is called deciduous.
3. Look for evergreen trees, tell the names of trees, observe the characteristics of leaves, and know that some leaves are thick and waxy; Some leaves are small, thin and thick, and will not fall off in winter. This kind of tree is called evergreen tree.
4. Inspire children to discuss the difference between evergreen trees and deciduous trees, and let them know that leaves are green because they contain a lot of chlorophyll, and leaves also contain a yellow and orange substance called carotene. When the climate gets cold, the chlorophyll of deciduous trees decomposes, and carotene turns the leaves yellow or orange. Chlorophyll of evergreen trees will not decrease, which makes evergreen trees stay green in winter.
5. Pick up the fallen leaves and step on them.
Teaching plan 5 of "Evergreen Trees and Deciduous Trees" in large class scientific activities Intention:
There are all kinds of trees around our lives, which will change with the seasons. Leaves fall with the wind, and some trees have no leaves. Children are interested in understanding and exploring, so they launched the activity of "Deciduous Trees and Evergreen Trees". Let the children abstract some common characteristics of trees on the basis of understanding them, and let the children observe and compare them themselves, so as to know the difference between evergreen trees and deciduous trees and answer the questions themselves. Not all trees turn yellow and lose their leaves in autumn. Some trees are evergreen all year round and autumn is no exception. These trees are called evergreen trees. Trees that turn yellow and lose their leaves in autumn are called deciduous trees.
Activity objectives:
1, know the remarkable characteristics of evergreen trees and deciduous trees.
2. Feel the importance and benefits of trees to people's lives.
Activity preparation:
Leaves of various deciduous trees and evergreen trees, two pictures of trees with their own characteristics.
I. Review experience and surrounding trees
1. (showing the Chinese character "tree") Where have you seen trees?
Summary: There are trees on the roadside, parks, communities, rivers and at home.
2. Which of these trees do you know?
3. What are willows like in winter?
(1) Understanding Deciduous Trees
Show two pictures to see the difference between the two trees. (Showing pictures of willows) Do you know this tree? what kind of tree is it? Look, what's wrong with this tree? (I know the new word bare-bare means all the leaves have fallen off), by the way, this tree is bare. Is it so bare all year round? Then when did it grow leaves? (Children say) It turns out that the willows are so lush in spring. Why do they become bare now? (Leaves fall)
Summary: We call willow a deciduous tree whose leaves germinate in spring and all fall off in winter.
Let the child say the name several times.
(2) Know evergreen trees
(Pointing at the camphor tree) Do you know this tree? This is our city tree in Jiangyin-Cinnamomum camphora. What is this? What do you find about the leaves on the camphor tree? There are many leaves on camphor tree. We can call it lush. What's it called? Does camphor tree not shed leaves all the year round? how do you know It turns out that Cinnamomum camphora also leaves, but after it leaves, are there any leaves on the tree? (Yes)
Summary: A tree like Cinnamomum camphora, which has green leaves all year round, is called evergreen tree. Let the child say the name several times.
Teaching Plan 6 "Evergreen Trees and Deciduous Trees" Large Class Scientific Activity Objectives;
1. Understand that trees have evergreen trees and deciduous trees, and observe and compare their differences.
2. Know several evergreen trees and deciduous trees, and know their names.
3. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
4. Learn to record your findings in various forms such as language and symbols.
5. During the activity, let the children experience the joy of success.
Activity preparation:
Teaching aid preparation: collect all kinds of leaves and some pictures about evergreen trees and deciduous trees.
Activity flow:
First, lead the children to observe outdoors and pick up fallen leaves.
1. Use children's walking time to lead them to pick up fallen leaves.
Teacher: When the children were walking today, the teacher asked you to go to the kindergarten to pick up a lot of leaves. Look at how many leaves have been picked up first, and then see what the difference is.
2. Guide the children to observe the leaves carefully and talk about the leaves they see.
Teacher: What kind of leaves, shapes and colors do you see?
Classroom summary: Just now, the teacher asked the children to pick up a lot of leaves, and found that some leaves were yellow, and some were …
Second, share your observations collectively.
1, Teacher: Now it's winter. These leaves are all winter leaves. Have we found any changes in the leaves? Did all the leaves on the tree fall off?
Teacher's summary: In winter, some trees turn yellow and slowly fall, while others are still green.
2. When winter comes, why do some trees have a lot of fallen leaves and some trees have little or no fallen leaves? (Guide children to discuss in an orderly manner according to the existing experience)
The teacher concluded that some trees are evergreen trees, which are green all year round. Some trees are deciduous. Every autumn, the leaves will turn yellow and gradually fall, and new leaves will grow in spring.
Third, know several evergreen trees and deciduous trees, and know their names.
1. Show pictures of evergreen trees and guide children to look carefully. What is the shape of the leaves? What color is that? What's the name of this tree? The teacher will tell you.
2. Show pictures of deciduous trees. Look at them again. This is a deciduous tree. What are their leaves like? What about the color?
3. Let the children observe carefully and see what's the difference between these trees.
Teacher's summary: Evergreen leaves are hard, smooth, thick and moist; There is wax on the surface. The leaves of deciduous trees are soft, rough, thin and have no moisture.
4. The experience of migrating children, talk about what is evergreen and what is deciduous.
Teacher: Children, do you know evergreen trees and deciduous trees? Will you tell the children in the class what you think?
The teacher once again showed some pictures of evergreen trees and deciduous trees to enrich the children's understanding of evergreen trees and deciduous trees.
Activity reflection:
This activity is a comparative observation of two kinds of objects. During the activity, children quickly grasped the concepts of "deciduous" and "evergreen" by watching videos twice, adding targeted questions from teachers and children's zero-distance observation of leaves, got to know deciduous trees and evergreen trees, and found the difference between evergreen trees and deciduous trees.
Large class science "Evergreen Trees and Deciduous Trees" Teaching Plan 7 Activity Objectives:
1. Distinguish between evergreen trees and deciduous trees, and feel the benefits that trees bring to people.
2. Feel the fun of placing trees.
3. Develop children's thinking and oral expression skills.
4. Cultivate children's keen observation ability.
5. Explore and discover the diversity and characteristics in life.
Activity preparation:
1. Pictures of common tree species in various places.
2. There are several evergreen leaves and fallen leaves, and the child has one evergreen leaf and one fallen leaf.
3. Three different kinds of toy trees (***9 trees).
4. A photo of camphor leaves and camphor trees with fallen leaves all over the ground in spring.
5. The essay Tree is Good.
6. Chinese characters "Tree", "Evergreen Tree", "Deciduous Tree" and "Nice Tree".
Activity flow:
First of all, the surrounding trees
1. (showing the Chinese character "tree") This is a "tree". Where have you seen a tree?
Summary: There are trees on the roadside, parks, communities, rivers and at home. There are trees everywhere in our life.
-In this session, children's expression is basically a review of experience, so everything can be carried out around the center.
Second, the tree of knowledge.
1. Do you know which of these trees?
-This is also to arouse children to review and exchange the names of known trees around them.
In the activities, children's memories of the past are not as rich as they thought. However, the names of buttonwood and willow can be remembered.
When the child talked about willow, the teacher went to the next step.
There are many willows near your West Lake. Willow is green, what season is coming?
-This is the specific situation. It can be amended as "There are many willows in our kindergarten" or "There are many willows beside our xx".
Spring has come, and the leaves of willow trees are green, but do you know what willow trees look like in winter?
Third, distinguish evergreen trees from deciduous trees.
1. (Showing the Chinese character "Deciduous Trees") Trees like willow, which germinate in spring and lose their leaves in winter, are called "Deciduous Trees". In addition to deciduous trees, there is another tree that has leaves all year round, called "evergreen tree".
2. (Show two kinds of leaves) Here are two kinds of leaves, one is evergreen and the other is deciduous. Please take one for everyone.
-The word "every" is used here because some keywords are not understood by large-class children when they attend interviews in primary schools, so some such keywords can appear in time in the learning activities of large-class children.
In the activity, the child only took one piece at first, so the teacher explained, "There are several things, one is to take one piece, and the other is to take one piece." Children can understand at once.
Please have a look and feel. What's the difference between these two leaves?
-Here, the different characteristics of leaves are perceived through the senses. During the activity, according to the children's feelings, the teacher recorded the characteristics of two kinds of leaves on paper with "evergreen trees" and "deciduous trees" for inductive use.
During the activity, children will tell the irrelevant characteristics of two leaves, such as size. Therefore, when selecting leaves, these factors should be excluded as much as possible, and its distinctive features (evergreen tree) should be abstracted: thick leaves, dark front and luster.
The teacher concluded: You see, no matter which tree we see on the road, even if we don't know it, as long as its leaves are thick and black and its surface is shiny, we can judge that it is an "evergreen tree".
4. Distinguish the ownership of camphor trees.
(1) (showing the leaves of Cinnamomum camphora) Is this the leaves of evergreen trees or deciduous trees?
-Here, by causing another contradiction, we can complete our understanding of evergreen trees. During the activity, the children agreed that "this is an evergreen tree".
(2) (Showing photos of camphor trees falling all over the floor) This is what camphor trees look like now, with fallen leaves falling all over the floor. After reading this photo, do you still think camphor tree is an evergreen tree?
During the activity, many children immediately changed their views: I think it is deciduous trees. The teacher asked: Why? Some children still think it is an evergreen tree. The teacher also asked: Why? (Show the book Plants) The name of this book is ... (All the children in the big class know it) Yes, this book is all about plants. Let me see. What kind of tree is camphor tree? During the activity, the teacher read: "Cinnamomum camphora has leaves all year round, but after it leaves, it grows new leaves immediately." So although there are always leaves, there are dense leaves all year round. It is an evergreen tree. "
-through the collision of this understanding, a complete conceptual understanding may be formed. In addition, when children are hesitant, the desire to listen is also the strongest. At this time, it will be very effective for the teacher to "read" according to the book.
Fourth, plant trees together.
1. Deciduous trees and evergreen trees constitute the greening and forests around our lives. Beside your West Lake, besides willows, there are … (not asking questions, but waiting like this).
2. (Showing a picture of pink willow and green willow by the west lake) The gardener by the west lake is good at planting trees. When planting trees, they planted a peach tree first and then a willow tree, so they planted a row of peach trees and willows. In spring, peach trees are red, willow trees are green, peach trees are red and willow trees are green. Very nice. You know, foreigners like Mr. Ying come to Hangzhou to see the peaches and willows by the West Lake.
-Put the calculation teaching in the children's real life background, so that children can understand it more easily, and at the same time, mathematics has practical significance.
If you want to plant these trees by the lake in Shanghai (pointing to the school tree on the table), what can you do to make the trees look as beautiful as the gardener of the West Lake and make people want to see the trees you planted?
3. Explore the cooperative operation of children.
At this time, if the child doesn't know how to cooperate, you can prompt: Can you put these trees in a row with them in your hand? It is better to discuss planting with friends. During the activity, after being reminded, children can generally organize the learning tool tree together in groups of three or five.
4. Exchange their methods of planting trees.
Here, teachers and children summarize several different ways of planting trees together and tell children that there are many ways of arrangement. "When you are in regional activities, you should think slowly."
Five, the tree is really good.
1. Teacher: Our ancestors planted many trees, so what do you want to do under them?
Summary: We can do many things under the tree, yes, "the tree is really good". (Chinese characters appear at the same time)
2. (Show the book) The name of this book is "How nice the tree is". Here are some books (the teacher handed them to some children) for your friends.
-Let the children pass on the books to others, aiming at developing the habit and quality of "putting others before yourself" in every bit of life. At the same time, put soothing music as the background to adjust and enhance the reading atmosphere and mood.
3. Listen to prose poems while reading.
-During this period, you can ask "Which page was I on" 1 ~ 2 times to test your reading ability.
4. How many pages does this book have? Trees have many benefits. I hope you can make this book thicker.
-Prose continuation activities to explain district corner activities.
Activity reflection:
Children's prose poetry is an important part of literature appreciation teaching in kindergartens, and it is also a favorite reading for children. In the organization and guidance of prose poetry teaching, whether teachers can adopt appropriate teaching methods and strategies to convey the inherent information contained in prose poetry to children with high efficiency and high quality will directly affect children's understanding, experience and feelings of prose poetry, and give full play to the educational value of prose poetry teaching. Therefore, how to organize and guide prose poetry teaching is a problem that kindergarten teachers have been discussing.
Children in large classes have greatly developed their language expression ability and creativity. So we change the whole learning process into appreciation, instead of using "Who will like trees and why?" This question allows children to boldly create poems with their own language actions according to the content of the picture, and does not require the same as the original. The activity begins with the first sentence in the poem, "It's good to have a tree. Birds can nest in it. Every day at dawn, birds will chirp. " Let them talk about why the bird likes trees and what it is doing in them. Then a teacher plays the mother tree and the children play the birds to fully express their understanding of prose. Then, guide the children to observe the small pictures and express their understanding of the pictures with the sentence pattern of "It's good to have a tree, …". The teacher summarized and arranged on the basis of the children's creations. Finally, bind all the pictures into a big book, let the children name the big book and give them proper environmental education.
Teaching Plan 8 "Evergreen Trees and Deciduous Trees" Large Class Scientific Activity Objectives:
1, willing to explore different trees, can initially distinguish between evergreen trees and deciduous trees.
2. Feel the joy of picking up fallen leaves and stepping on them.
Activity preparation:
Choose a field with evergreen trees and deciduous trees.
Activity flow:
Introduce the topic first.
It's getting colder and colder. Let's go and see what will happen to those trees.
Look for evergreen trees and deciduous trees.
1, looking for deciduous trees.
Say the names of trees and observe the changes of leaves. We know that some trees will start to grow leaves in autumn and winter.
Turn yellow, turn red, fall off, and wait until the next spring to grow new leaves. Such trees are called deciduous trees, such as willow, sycamore and phoenix tree.
2. look for evergreen trees.
Tell the name of the tree, observe the characteristics of the leaves, and know that some leaves are thick and waxy; Some leaves are small, thin and thick, and will not fall off in winter. This kind of tree is called evergreen tree.
Third, discussion: the difference between evergreen trees and deciduous trees.
Let children know that the leaves are green because they contain a lot of chlorophyll, and the leaves also contain a yellow and orange substance called carotene. When the climate gets cold, the chlorophyll of deciduous trees decomposes, and carotene turns the leaves yellow or orange. Chlorophyll of evergreen trees will not decrease, which makes evergreen trees stay green in winter.
Fourth, step on fallen leaves and pick them up (bring them back)
5. Make leaf specimens.
