In daily study, work or life, many people have had the experience of writing letters, and they are all familiar with letters. Letters are a tool for people to communicate with each other about their emotions and thoughts. There are many things to note when writing a letter. Are you sure you know how to write it? Below is the natural enemy matching lesson plan for science activities for large classes that I compiled. It is for reference only. I hope it can help everyone. Lesson Plan for Natural Enemy Pairing of Science Activities for Large Classes Part 1

Activity goals:

1. Perceive the diversity of animal species in nature and know the inseparable connection between animals and humans.

2. Know the relationship between animals’ natural enemies and be able to accurately pair them.

3. Cultivate children’s love for animals.

4. Cultivate children’s curiosity about things and be willing to boldly explore and experiment.

5. Stimulate children’s interest in scientific activities.

Activity preparation:

1. Courseware for various animals.

2. Several magnetic pictures of natural enemy animals.

3. Preparation of children’s knowledge and experience about animals.

Activity process:

1. Play the animal courseware and ask the children to name the animals and their habits.

First use the various sounds of animals to arouse children's interest. Hear the sounds and say the name of the animal. Then play the picture of the animal and ask the children to tell you what its name is and what it looks like.

Example: "What did you hear?" (the cry of a little frog) "By the way, it's a little frog. Can anyone tell me what the little frog looks like?" (for young children) Play the picture after finishing talking)

2. Show the paired pictures of natural enemies to let the children understand what natural enemies are and which animals are natural enemies.

Show the picture, "Look at the picture in the teacher's hand. Which two small animals are they? What is their relationship?" (The two of them are enemies. The frog will kill the bug. Eaten)

Let children understand the meaning of the word "natural enemy".

"So, do you know which small animals are natural enemies?" the children replied after discussion.

3. Place pictures related to natural enemies in an irregular manner and ask children to operate them.

After the pairing is completed, ask the children to say in complete words "xxx and xxx are natural enemies."

4. Understand the importance of animals to people, and we must protect small animals.

We humans cannot live without animals. There is an inseparable connection between animals and humans. Please ask children to talk about relevant examples based on all their personal experiences.

Activity suggestions:

1. Observe the appearance, characteristics, and habits of animals before activities to understand the animals.

2. Children can watch some clips of natural enemies together to understand the meaning of natural enemies more vividly.

Activity extension:

Pictures of natural enemies can be placed in regional activities, allowing children to pair up and talk about who is a natural enemy with whom and why. Lesson Plan for Natural Enemy Matching in Science Activities for Large Classes Part 2

1. Activity Objectives

1. Understand the life characteristics of insects and recognize the natural enemies of common insects.

2. By understanding the role of natural enemy insects, children can enrich their life experience and improve their ability to solve life problems.

2. Activity preparation:

Courseware introducing the living habits of insects, dragonflies, seven-spotted ladybugs, spiders, frogs, swallows, etc. and pictures of related insects.

3. Activity process:

1. Invite several animal friends, ask the children to tell their names, and distinguish which ones are insects and which ones are not, and why?

"Do you know what these animal friends eat?" The question is introduced to trigger children's existing experiences and discuss them.

2. Invite children to watch the courseware about the living habits of animals

(animals introduce themselves to the insects they like to eat, and pictures of insects appear), and guide children to discuss:

(1) Are mosquitoes, aphids, flies, and locusts pests or beneficial insects? Why?

(2) In addition to being eaten to death, what other reasons would cause these insects to die?

(3) Summary: Insects, in addition to being eaten during their lives, can also die due to virus infection.

3. Introducing the natural enemies of insects:

(1) What are the natural enemies of insects? During the growth and development of insects, they often die due to predation or parasitism by viruses, insects, and animals. These organisms are called natural enemies of insects. For example, if a frog eats a locust, the frog is the natural enemy of the locust; if a dragonfly eats a mosquito, the dragonfly is the natural enemy of the mosquito.

(2) What types of natural enemies are there of insects? Watch the courseware and ask the children to talk about how insect natural enemies eat insects?

The teacher guides and summarizes:

Trichogramma lays its eggs in the eggs of cabbage bug, diamondback moth, cotton fly, and corn borer.

Trachomatis wasps lay their eggs inside the eggs of insects and slowly grow up by absorbing the nutrients of the insect eggs. This natural enemy is called a parasitic insect natural enemy.

When ladybugs eat aphids, they eat them directly. These insects that eat insects directly are called predatory insect natural enemies. The mantis preys on most insects, and it is also called a predatory insect natural enemy.

Spiders use their webs to hunt insects, such as locusts, dragonflies, mosquitoes, flies, etc., anesthetize these insects, and then slowly suck out their body fluids. This kind of spider that only preys on insects Natural enemies are called insectivores. Frogs eat pests and swallows hunt locusts. Frogs and swallows are also natural enemies of insects.

4. The use of natural enemies of insects:

"What will the farmer do if there are insects in the vegetable field?" Guide children to know some pest control methods - spraying pesticides and catching vegetable insects wait.

What other methods are there? Guide children to use the role of insect natural enemies to think and solve problems.

How to protect these beneficial insects? Guide children to learn to protect beneficial insects and eliminate pests. Top Class Science Activity Natural Enemy Matching Lesson Plan Chapter 3

Activity goals:

1. Understand the various natural enemies during the growth period of crops and the various methods farmers use to protect crops, which will help farmers develop their wisdom. Respect.

2. Be able to actively participate in the game of fighting against natural enemies and feel the joy of defeating them.

Activity preparation:

Courseware

Activity process:

1. Introduction questions

Teacher: Today’s teacher I brought some pictures that told us a very nice story. Let’s see what is the title of the story? (Show slides) Guess what natural enemies crops have?

2. Children watch the slides and express boldly and freely based on the content.

1. Who is in the story? What happened.

2. Children express freely.

3. Group reading.

1. Teacher: Is it really the same as what you said? Let’s take a closer look together.

4. You have thought of so many good methods, let’s see what the farmer uncle comes up with.

5. Have the pests been eliminated? Where did you see it? Is this method good?

6. Summer is here, and bunches of rice ears are growing on the crops. How does the farmer uncle feel?

7. Will it be like what the farmer uncle thought? Let's take a look.

8. What did you see? What happened?

9. How does the farmer uncle feel? What to do?

10. Thanks to the children for helping the farmer uncle, the crops can finally grow healthily again. If it grows well, there will definitely be a good harvest.

IV. Complete appreciation

Teaching reflection:

1. The pictures in the courseware are not rich enough. More pictures of pests and control methods should be provided, so that It is more helpful for children's understanding.

2. Children are very interested in the activities, but they do not speak enough. Children should be given more opportunities to express their ideas.

3. The knowledge preparation of pre-class teachers is not sufficient. Lesson Plan for Natural Enemy Pairing of Science Activities for Large Classes Part 4

Activity goals:

1. Preliminarily understand the mutual constraints and interdependence between animals.

2. Through activities, accumulation of knowledge and experience, and experience sharing, understand the pairwise correspondence between friends and enemies among animals.

3. Develop a preliminary awareness of ecological protection and develop an interest in exploring nature.

4. Cultivate children’s curiosity about things and be willing to boldly explore and experiment.

5. Develop children’s observation and imagination.

Activity preparation:

1. With the help of parents, look for pictures and information about animal friends and natural enemies in advance.

2. Learn to sing the song "I Love My Little Animals".

3. A physical projector.

Activity process:

1. The song "I Love My Little Animals".

Encourage children to create small animals and then create big animals.

2. Use cats and mice to guide children to discuss the hostile relationship between animals.

1. Do you know who mice are most afraid of? Why? Are they good friends or enemies?

2. Are sheep and wolves good friends or enemies? Why?

3. What other animals do you know and which animals are enemies? Teachers encourage children to speak boldly.

4. Put the collected pictures on the projector for everyone to enjoy.

For example: snakes and frogs, geckos and mosquitoes, lions and zebras, etc.

3. Guide fish and sharks to guide children to discuss the friendship between animals.

1. Some animals are enemies, and some are good friends. For example, guide fish and sharks are a team of good friends. Because sharks have bad eyes, guide fish can guide the shark and eat. Shark leftover food.

2. What other animals do you know and which animals are friends?

4. Help young children form a preliminary awareness of ecological and environmental protection.

It is the law of nature that animals eat other animals or be eaten by other animals. If there are too many animals of one kind or the disappearance of one kind of animal, it will have an impact on nature. Therefore, we need to protect various animals and bring balance to nature.

Activity reflection:

Initially cultivate children's love for animals, stimulate children's love for nature, and stimulate children's interest through the display of pictures. However, some problems also occurred in the subsequent teaching process. The order and atmosphere of the classroom were not effectively controlled. The next activity process needs to be further improved and perfected. Moreover, children in the upper class like to talk more and cannot listen patiently. Of course, in this kind of activity, children still have many points of interest, and they want to know and understand animals even more.

And its cute and naive appearance has always attracted the attention of children, especially its eyes that always like to open and close, which is very interesting! Children really like owls! They also said that they must see owls with their own eyes if they have the opportunity in the future! The whole activity , has always been filled with the children's innocence, kindness, and warm love. The preset teaching objectives were well accomplished. Lesson Plan for Natural Enemy Pairing of Science Activities for the Big Class Part 6

Textbook Analysis:

"Animals' Natural Enemies and Friends" is a small activity under the second theme activity in the science field for the next semester of the big class. The main purpose of this activity is to let children have a preliminary understanding of the mutual constraints and interdependence between animals, form a preliminary awareness of ecological protection, and know that animals and us humans live together in the global village, and we are partners for survival. , we must learn to live in harmony with animals.

Design intention:

Although today’s children like small animals very much, they know very little about animals, and they are not very clear about the relationship between animals. These need to be taught. be solved gradually. In this activity, I captured the child's nature - his interest in small animals. Starting from the child's interest, I launched a series of activities that the child likes, from shallow to deep, from easy to difficult, in line with the child's cognitive rules. I mainly let children watch animal videos to stimulate their interest in animals, understand the relationship between animals based on pictures and videos, and form a preliminary awareness of ecological protection.

Activity goals and focus:

1. Preliminarily understand the mutual constraints and interdependence between animals.

2. Form a preliminary awareness of ecological protection.

Activity preparation:

1. Collect pictures and information about animals’ friends and natural enemies.

2. Videos "Animal World", "Aphids and Ants", and "Protect Animals".

3. Light music.

Activity process:

2. Question: What animals did you see in the video just now? What is the relationship between them?

2. Introducing pictures of cats catching mice to guide children to understand the "enemy" relationship between animals.

1. Show pictures of cats and mice, snakes and mice, eagles and snakes, mantises and cicadas, so that children can understand that some animals are "enemy" relationships.

2. Guide children to understand the concept of "natural enemies": if one animal preys on or harms another animal, the former is the latter's natural enemy.

3. Give examples to illustrate the concept of "natural enemies". For example: cats are the natural enemies of mice, eagles are the natural enemies of snakes, snakes are the natural enemies of mice, and cockroaches are the natural enemies of cicadas.

4. Children’s thinking: the relationship between weasels, roosters and centipedes.

3. Show videos of aphids and ants to elicit the "friend" relationship between animals.

2. Analyze the reasons why ants and aphids are interdependent.

3. Introduce and analyze the relationship between rhinoceros and rhinoceros bird, sea anemone and hermit crab, clown fish and sea anemone, so that children can understand the mutually beneficial relationship in the animal kingdom.

4. Children think: "What is the relationship between sharks and guide fish, crocodiles and toothpick birds, seals and penguins? Why is there such a relationship between them?

4. Summary and reflection:

What are the relationships between animals? What are the relationships between animals?

Extended activities:

Play " "Protect Animals" video to understand the food chain relationship between animals and form a preliminary awareness of ecological protection.

Activity micro-reflection:

This micro-lesson fully reflects the origin of scientific activities. The concept of life, return to life, and higher than life, the teaching links are clear and clear, the teachers teach clearly, the multimedia is used appropriately, the pictures are vivid, and have strong appeal, and can easily solve the difficult problems about animal relationships in the theme activities. The activity time is only 7 minutes, which facilitates fragmented learning for children.

Micro-reflection on the activity

1. Analysis of the teaching material "Animal Enemies and Friends" is in the field of science in the first semester of the large class. A small activity under the second theme activity. The main purpose of this activity is to let children have a preliminary understanding of the mutual constraints and interdependence between animals, so as to form a preliminary awareness of ecological protection and let children know about animals and us humans* **We live together in the global village, we are partners for survival, and we must learn to live in harmony with animals.

2. Design Intention: Although today’s children like small animals, they know little about animals. The relationship between animals is not very clear, and these need to be gradually solved in teaching. In this activity, I captured the child's nature - he likes small animals, and started a series of children's interests. The activities they like are arranged from easy to difficult, from easy to difficult, in line with children's cognitive rules. I mainly let children watch animal videos to stimulate children's interest in animals, talk about the relationships between animals based on pictures, and deepen children's understanding through pairing. Form a preliminary awareness of ecological protection. Let children perceive the relationship between animals in games and develop their awareness of protecting animals. They are in line with the "Outline" and are interested in surrounding things and phenomena, and have curiosity and thirst for knowledge; they can use Use various senses, use hands and brains to explore problems; be able to express and communicate the process and results of exploration in appropriate ways

3. Activity goals and key points

1. Recognition. Knowledge goal: Preliminary understanding of the mutual constraints and interdependence between animals.

2. Emotional goal: Forming a preliminary awareness of ecological protection. Activity focus: Preliminary understanding of the existence of animals. Difficulty of the activity of mutual restriction and interdependence: accurately pair animals according to their relationship with friends and enemies.

4. Activity preparation:

Experience preparation: Children know some. Names of common animals.

Material preparation: 1. Collect pictures and information of animals’ friends and natural enemies.

2. Animal World video, "I Want to Have a Home" video, song "I Love My Little Animals"

5. Teaching and learning methods:

Teaching method: The "Outline" points out that teachers should become supporters, collaborators, and guides of children's learning activities, pay attention to children's performance and reactions in activities, be sensitive to their needs, and respond in an appropriate manner in a timely manner. , forming a cooperative inquiry-based teacher-student interaction. Therefore, in this activity, I adopted the physical introduction method, multimedia demonstration method, guided discovery method, language stimulation method, scenario creation method, and individual guidance method. Study method: The "Outline" points out that conditions should be created as much as possible for children to actually participate in inquiry activities, so that they can experience the process and methods of scientific inquiry and experience the joy of discovery.

Therefore, in this activity, the specific learning methods for children include: observation method, operation method, and discussion method.

VI. Activity Process

I designed the activity process into four links.

(1) Create an atmosphere and introduce passion. The teacher plays the "Animal World" video to arouse children's interest in animals and names the common animals, and asks: What is the relationship between them? It naturally introduces new lessons, arouses children's thinking, and stimulates children's desire to explore.

(2) From the shallower to the deeper, clarify the relationship. First, show the mouse puppet to arouse the child's interest, and also ask the question: Who is the little mouse most afraid of? Why? Introduce the relationship between cats and mice, and then make a summary to introduce the concept of "natural enemies"; then let the children deepen their understanding by looking at a series of pictures and stimulate the children's desire to discuss and communicate; then let the children talk about other animals It is the relationship between natural enemies. In this way, the task of children's understanding of "natural enemies" is completed. Next, show the guide fish and shark, guide the children to discuss the friendship between animals, and introduce it naturally. Then use the same method to guide children to understand the friendship between animals.

(3) Expand and extend, let your wishes fly. In this session, I first played the video "I Want to Have a Family" to stimulate children's awareness of protecting animals. Then I organized children to discuss: How should we protect animals with animals? Encourage children to put their thoughts into action. Then finally make a summary with the children to make them more aware of ecological protection. Finally, encourage children to continue exploring the relationship between animals so that their interests can be extended. Top Class Science Activity Natural Enemy Matching Lesson Plan Part 7

Activity goals:

1. Understand the content of the story, focusing on how the tortoise dealt with the fox tactfully.

2. Learn to tell the important dialogues in the story, learn to use language and actions to boldly express your understanding of the work, and try to express the sense of humor contained in the work.

Activity preparation:

1. The children’s book contains pages 24 to 26.

2. Wall chart "The Smart Turtle".

3. Language tape.

Activity focus:

Understand how the tortoise treats the fox tactfully.

Activity difficulty:

Learn to tell important dialogues in stories.

Activity process:

1. Talk and perform stories to stimulate children’s interest.

A clever tortoise defeated a cunning fox. Do the kids want to hear it?

2. What about the story of "The Smart Turtle"?

(1) Children appreciate the story completely and have a preliminary understanding of the content.

(2) Who is in the story? Is the tortoise's method of dealing with the fox smart?

3. Combined with the wall chart, appreciate the story in sections.

(1) What happened to the fox and the turtle?

(2) The fox wants to eat the turtle, what should the turtle do?

(3) The turtle was afraid of falling and fire, so why did he let the fox throw him into the sky and throw him into the brazier? Guide children to discuss with each other, encourage children to work in pairs, and learn to talk by role with expressions.

4. Children listen to the story recording and fully appreciate the story again.

5. Combined with children’s books, learn the dialogue between the turtle and the fox in the story.

(1) Children learn the dialogue in the story. The teacher focuses on guiding the children to pay attention to the tone, intonation and expression when telling, to help the children understand the cleverness and wit of the turtle.

(2) The teacher reads the dialogue between the narration and the fox, and collaborates with children with strong understanding and expressive abilities to perform the dialogue.

(3) Children are divided into groups of three and perform dialogues in different roles.

Teaching reflection:

"The Smart Turtle" is a story with strong meaning, contrasting language and characters, and vivid images. Through the interesting dialogue between the tortoise and the fox in the story, children will learn to be resourceful, brave, and use their brains to find ways to solve problems when encountering difficulties and dangers.

In the process of narrating the story, I made an exaggerated narration based on the animals and dialogues that appeared in the story. The continuous exaggeration of the language made the children deepen their interest in this activity. This lays a good foundation for children's in-depth understanding of the story. During the activity, I raised several open questions, which allowed the children to develop more rich associations, reason and hypothesize various plot developments, and be able to express them boldly. However, in the process of expression, the children in the small class Language development is not perfect, so some children's expressions are incomplete.

If children can perform relevant scene performances during the activity, it can better reflect the atmosphere, so that children can not only learn the simple dialogue of the characters in the story, but also have a deeper understanding of the story.
