Teaching plan for middle class "Little Potatoes"

As an outstanding teacher, it is necessary to prepare detailed lesson plans. The lesson plans help students understand and master systematic knowledge. How to write a lesson plan? The following is the middle class lesson plan "Little Potatoes" (selected 5 articles) that I compiled for your reference. I hope it can help friends in need. Middle class lesson plan "Little Potatoes" Chapter 1

Activity goals

1. Understand the growth process of potatoes and stimulate the desire to explore the mysteries of plants.

2. Know how to eat potatoes and like to eat potatoes.

3. Be willing to try boldly and share your experiences with your peers.

4. Cultivate children’s hands-on ability through practical operations.

Activity preparation

Pictures: pictures of edible potatoes, growing potatoes, sprouting potatoes.

Activity process

1. Show potato chips to arouse children’s interest. Teacher: What is this? Have you ever eaten it? What is it made of?

< p> Preschool discussion teacher: This is what we usually call "potato", and it also has a name called "potato". Today we are going to get to know potatoes.

2. Understand potatoes and their growth process

1. Show the picture: Potato Teacher: What is this? It also has a name, do you know what it is called?

2. Show pictures of sprouted potatoes.

Ask the children to see what is different about this potato?

Teacher: Observe carefully and see where the potatoes are most likely to grow sprouts?

Guess it Will the sprouts grow leaves and produce new potatoes if they are buried in the soil?

3. Understand the growth process of potatoes

(1) Let the children discuss: What will happen if a sprouted potato is cut into several pieces and buried in the soil with the cut side down?

(2) Teacher: The roots and buds of potatoes grow day by day.

Potato roots grow from where there are buds. Do you know where the buds grow?

Towards the ground or to a sunny place?

After discussion, the children learned that buds grow towards places with sunlight.

(3) Teacher: When did the leaves grow? When you see the tender leaves growing out of the ground, you will know that there is a potato tree here.

(4)Teacher: The leaves grow more and more, what happens underground?

(Children discuss freely.)

(5)Teacher: The baby potato is about to grow. Do you know where it will grow?

It turns out that it grows at the front end of the root. The baby grows underground, and beautiful flowers bloom on the ground!

(6) Question: When can we dig potatoes out of the soil?

(7) Show pictures , observing the ripe potatoes in the field.

Teacher: The flowers have withered and the leaves have withered. At this time we can dig out the grown potatoes.

4. The teacher summarizes the process of potato growth:

Cut the sprouted potatoes into pieces, bury them cut side down in the soil, with sufficient sunlight and moisture. They sprout and grow roots. When they are exposed to the ground, they grow tender leaves. After many leaves grow, beautiful flowers bloom. The baby potatoes grow up slowly in the soil. When the flowers and leaves wither, the potatoes grow up and we can have eaten.

3. Eating potatoes

1. Question: Can all potatoes be eaten? Can the ones with sprouts and those that have turned green be eaten?

< p>Teacher: Potatoes that have grown sprouts or have turned green contain toxins and cannot be eaten.

2. Question: How can potatoes be eaten?

Children’s discussion

3. Show pictures of food made from potatoes. Teachers and children summarize the methods together: Yes Fry, stir-fry, boil, bake. Cut into chunks, shreds, whole, mashed potatoes, etc.

Teacher: Do you want to eat potatoes? Go home and make delicious potato food with your parents! Middle class lesson plan "Little Potatoes" Part 2

Activity focus

Understand the story and discover through experiments the phenomenon of potatoes floating in salt water.

Difficulties of the activity

Encourage young children to cooperate with peers to conduct experimental operations in an orderly manner and record their findings.

Activity preparation

Sugar, salt, MSG, potatoes, disposable transparent cups with red, yellow and green lines on them, plastic cups, recording paper, markers, "The Adventures of Baby Potato" 》(courseware), a video.

Activity process

1. Raise questions.

1. Show potatoes: What is this? (Potato)

2. The teacher tells the first part of the story.

3. Question and verify: Guess what happens when potatoes fall into water?

(Going straight to the theme of the activity, the question "Guess what will happen if a potato falls into the water" allows children to make bold ideas based on their own experience, so that teachers can promptly understand what children have already acquired. What experiences about ups and downs will provide basis for subsequent activities)

4. Tell the second part of the story.

(Value analysis: Children’s thinking is intuitive and visual, and they need to have specific perceptions of things. Therefore, I use vivid, dynamic and realistic story courseware to elicit questions, which is reasonable, scientific, and standardized, and is in line with the development of children. level and understanding of rules.)

5. Discussion: Who saved the baby potato after it fell into the water? What do you think Brother Bai might be?

(Value analysis: The questions raised arouse children’s curiosity and thirst for knowledge, and stimulate children’s desire to experiment and explore.)

2. Collaborative exploration.

1. Present experimental materials. (Sugar, salt, MSG)

2. Explain the rules of the experiment: Two people work together to conduct the experiment. First, pour all the Bai Ge in the cup into the water cup with the same mark as them, and then stir it with chopsticks. Until they are completely dissolved, then put a piece of potato into each cup. Finally, please observe carefully. What interesting phenomena will occur? Record your findings on this recording sheet.

(Although the children in the upper class already have a strong sense of cooperation, for them, how to cooperate and the quality of cooperation are the most important, because this is directly related to the children’s thinking ability and collaboration. Ability. Their experience in cooperation is still relatively superficial. As a guide, the teacher clearly explains the rules of cooperative experiments and helps the children accumulate good cooperative experience)

3. Children’s experiments, teachers. Tour guide.

4. Communication: What did you discover in the experiment?

5. Experiment summary: From the experimental results just now, we can see that sugar, MSG and salt were put in the water, but neither sugar nor MSG could make the potato pieces float; only salt dissolved in the water can make the potatoes float. The block floats.

6. Experiment with two glasses of water with different salt contents: Will potatoes definitely float when placed in salt water?

(Value analysis: By manipulating materials, children each have their own feelings, experiences and discoveries, and form many stimulations and preliminary experiences in their minds. But these are still relatively general and relatively complex. Only through expression, communication and discussion of the inquiry process and results can vague characteristics and relationships be formed.)

3. Expansion of experience.

1. Show a picture of the "Dead Sea" and ask: Why can people float on the sea so leisurely and read a book? Does anyone know the name of this sea?

2. Watch the video introducing the Dead Sea.

/p>

Summary: It turns out that there is a lot of salt in the Dead Sea. Its salt content is ten times that of ordinary seawater. The water in the Dead Sea has very high buoyancy, so people can float on the sea.

IV. Activity extension:

1. The teacher showed two pots of potatoes of different sizes and asked: If they are placed in the same salt water, what will happen to the small potato pieces? Phenomenon? What about the big potato chunks?

2. Children’s guessing.

3. I won’t tell you what the outcome will be now. The teacher puts the materials in the laboratory of our class. You can try it yourself and you will know the answer!

(Value analysis: Use doubt to stimulate interest, use interest to stimulate doubt, and arouse children's desire to continue exploring.)

Activity analysis

1. In this activity In it, teachers use vivid animated stories to elicit questions, use multimedia technology to conduct dynamic and realistic simulations, and visualize abstract concepts, using clear and dynamic pictures to help children discover secrets, understand relationships, establish representations, and resolve difficulties. , so that children can gain intuitive, vivid knowledge and experience, which greatly improves the teaching effect. In particular, letting children watch a video about the Dead Sea shows them a seemingly profound scientific principle, making the activity content simple and interesting, and children are very interested.

2. In scientific activities, the most important thing for teachers is to help children discover secrets, understand relationships, establish representations, and resolve difficulties in the activities, so that children can gain intuitive, vivid knowledge and experience. In this activity, children not only learned about the phenomenon of potatoes floating in salt water, but more importantly, children tried to use better methods to cooperate with peers, such as a record, an experiment, a pour, a stir, etc. , the acquisition of this method will be beneficial to the child's life.

3. Before the experiment, the children put forward many ideas about "what might be Brother Bai", such as flour, sand, MSG, etc. If appropriate materials can be provided during the experiment, children can be fully aware that some are soluble and some are insoluble, which can expand children's experience.

4. The children were active in thinking and bold in expression throughout the activity. The teacher still lacked good interaction in some links, such as the questions raised by the children about the amount of salt and how to elicit questions in the experiment. etc. are still lacking and need to be improved in future teaching.

Teaching Reflection

The purpose of this lesson is to enable children to understand the clock, be able to distinguish the hour hand and the minute hand, understand the arrangement of numbers on the clock face, and have a preliminary understanding of the operation of the hour and minute hands. Rules, understand the whole point and the half point. In order to improve children's interest in learning, I use courseware teaching to enable children to grasp the purpose of teaching more intuitively and proactively while maintaining interest. Throughout the class, children learned proactively, the class atmosphere was lively, and knowledge acquisition and emotional experience were synchronized. I introduced the topic by visiting a clock shop, showing clocks of different shapes, sizes, and colors, and guiding the children to fully observe the places where the clock faces are the same. The children found them immediately, and every child couldn't wait to raise their hands. After answering the questions, the atmosphere in the class suddenly became high. Then, I guide the children to first observe and recognize the numbers 1-12 on the clock face, focusing on the positions of the four numbers 12, 3, 6, and 9. Understand the arrangement of 12 numbers and know that these numbers go in a clockwise direction. Then let the children recognize the hour hand and the minute hand, let the children carefully look at the difference between the two hands, and distinguish the hour hand and the minute hand according to the length and thickness of the hands. And through physical demonstrations, let children know the operating relationship between the hour hand and the minute hand. The two pointers move in one direction, which is called clockwise. The minute hand moves in one circle and the hour hand moves in one space. Through the demonstration, the children can see clearly. Interested. In the process of understanding the hourly time, I showed 12 hourly clock faces in the courseware, allowing the children to discover where the hour hand is and where the minute hand is at the hourly hour through observation. Then I will show a few hourly clocks to let the children consolidate their understanding of the hour. Then I asked them to take out the learning tool "Penguin Clock" and listen to the teacher telling the time. They would dial the hour. Because of the practical operation, most children mastered this link better.
