Deciduous trees and evergreen trees, a kindergarten class, contain the intention of reflection 1 activities;

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.

3. Cultivate children's curiosity about things and be willing to explore and experiment boldly.

4. In the activities, guide children to observe and discover phenomena carefully, and study scientific phenomena with empirical evidence.

5. Make children interested in exploring natural phenomena.

Activity preparation:

Leaves of various deciduous trees and evergreen trees, two pictures of trees with their own characteristics.

Activity flow:

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.

Second, understand the characteristics of evergreen trees and deciduous trees.

1, (showing the Chinese character "deciduous tree") A tree like willow is called "deciduous tree" because its leaves germinate in spring and fall completely in winter. 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.

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: No matter which tree we see on the road, even if we don't know it, as long as its leaves are thick, black and shiny, we can judge that it is an "evergreen tree".

Third, children distinguish evergreen trees from deciduous trees.

Now we see leaves, whether we know them or not, and we can tell whether they are evergreen trees or deciduous trees by their characteristics. On the back table are the leaves we picked together last time. Please put your evergreen leaves in the basket marked with evergreen leaves and the fallen leaves in the basket with fallen leaves. Did you hear me clearly?

Infant operation

Communication: Let's help them check if they are looking for it correctly. The teacher took out a leaf and asked the students to tell which tree it belonged to. Why? Where did you see it?

Fourth, distinguish the ownership of camphor trees.

(1) (showing the leaves of Cinnamomum camphora) Is this the leaves of evergreen trees or deciduous trees?

(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?

(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.

Five, the tree is really good, inspire children to love nature)

Teacher: Our ancestors planted many trees, so what do you want to do under them? What are the benefits of trees to us human beings?

2. Appreciate "trees are good" and understand the usefulness of trees.

Ask the children to talk about how we should care for trees in the future.

Summary: We can do many things under the tree, yes, "the tree is really good".

Activity expansion:

It turns out that leaves still have so many secrets. Let's go out and look for evergreen trees and deciduous trees.

Activity reflection:

A successful activity, the most important thing is to attract children to actively participate, take the initiative to gain knowledge and experience, and experience happiness. It is the primary goal of science education to guide children to have interest and desire in the characteristics and changing rules of common things and phenomena around them, so that children can gradually acquire a learning method and thinking habit in the process of exploration.

By paying attention to the changes of trees, the concepts of evergreen trees and deciduous trees are initially formed, and it is known that "trees that sprout in spring like willows and lose all their leaves in winter are called deciduous trees" and those that have leaves all year round are called evergreen trees. "Teaching activities emphasize process, emotional experience and ability training.

Before the activity, we should fully prepare the materials, fully consider the role and value that the materials can play in the activity, and the interaction form between the children and the materials. In this way, children can gain more experience and gain more in activities. The whole activity revolves around "leaves". Children learn and feel in a pleasant and relaxed atmosphere, which satisfies their curiosity and puts forward challenging learning requirements for the cultivation of their abilities of observation, comparison, language expression and listening.

Class 2 of deciduous trees and evergreen trees in kindergarten includes reflection 2 activity objectives:

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)

2, two pictures, intuitive (waxy properties-sealed with plastic paper)

Activity flow:

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)

Activity flow:

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 (6 points)

Color, surface, size, hardness, thickness, evergreen (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. There are five leaves, green, yellow-green, thick, soft and rough.

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. )
