Teaching plan of "floating and sinking" in kindergarten class

As an educator who gives lessons to others, he is usually asked to write a lesson plan, which is the basic condition to ensure the success of teaching and improve the quality of teaching. So do you know how to write a formal lesson plan? The following is the lesson plan "Floating and Sinking" that I compiled for you. For reference only, welcome to read.

1, the lesson plan of "floating and sinking" in kindergarten class

Water is indispensable in our daily life, and we can't live without water every day. Because of the close relationship between water and our life, children in large classes have been exposed to water for a long time, and children play with water naturally. In the process of playing with water, many interesting and novel phenomena are often found. Therefore, I choose the "ups and downs" phenomenon of objects in water as the object of science education. In the activity, I will provide rich and operable materials for children, so that children can explore, communicate and share scientifically in multiple senses and ways.

moving target

1. Understand the ups and downs of objects and learn to record experimental results.

2, interested in scientific activities, can actively explore and seek answers.

Through observation, communication and discussion, we can perceive the constant changes of things around us and know that everything is changing.

4. Experience the sense of accomplishment in solving problems.

Emphasis and difficulty of the activity

1, focus: a preliminary understanding of the ups and downs of objects.

2. Difficulties: Learn to use ↑↓ to record experimental results.

Activities to be prepared

Water, big basin, stone, leaves, keys, glass beads, small wood chips, foam boards, one-dollar coins, a record sheet for each hand and colored pens.

Activity process

1, import.

Teacher: Today we are going to do an interesting experiment.

Show a big basin full of water (put stones, leaves, keys, etc. Pre-placed in water) so that children can observe objects in water.

Q: What did you find? The children's answers will be limited to a few objects in the water.

Question: What are they like in the water?

2. Through observation and questioning, the theme of the activity-ups and downs.

(1) indicates that the symbol ↑ indicates floating on the water, and the symbol ↓ indicates sinking.

(2) Operational requirements: Guess in advance which objects will float on the water surface and which objects will sink. Record the answers to the guesses, then do the experiment, and finally record your own experimental results.

(3) The teacher demonstrates taking a small block of wood and letting children guess whether the block will float or sink.

(4) Teacher Introduction Record Sheet: This is the record sheet, and we will record the results on the record sheet later. For example, if a block of wood floats, it will be indicated by a downward arrow; If it sinks, it should be indicated by a downward arrow.

3. Children's autonomous operation experiment.

(1) Children practice independently according to their own wishes. Teachers should pay attention to observation and recording, and give targeted guidance to observe children's performance. Will a dollar coin float or sink? Right? Are other projects the same as we guessed? The teacher has prepared the water. Let's try it. After the test, we recorded the experimental results on the record sheet.

(2) Compare the two results according to the record form and exchange the final results.

Question: Is there the same experimental result as we guessed?

(3) Summary: Through experiments, we know that floating objects include leaves, foam boards and small wood chips.

The sunken items are: keys, glass beads, one-dollar coins, etc.

4. Lifting experiment operation: How to make sinking things float?

(1) Young children try to float things that were submerged in water.

Teacher: here is a problem: these sunken things are unhappy and want to float on the water. Let's think about something together, shall we?

(2) Children can operate freely and encourage them to try different materials and methods.

(3) Children introduce their own operation process.

5. Experience the upgrade and migration.

When there is a flood, we will sink into the water. Please try to save yourself from drowning?

Whoever has magical powers, but the water is very big, will also bring us harm. When there is a flood, things around us will sink into the water, and so will we. At this time, we should think about what we can do to keep us from sinking. Life buoy, wood, boat, footbath, etc.

6. End.

Invite friends to go home and continue to discuss how to sink floating objects.

Activity reflection

After organizing this "ups and downs" scientific activity, I found that children's interest is very high. Looking back on my teaching process, I made the following reflections on the whole activity.

First, expand the learning space and lay the foundation for children's development.

The "Outline" points out: "The choice of educational content should not only be close to children's life, but also help to expand children's experience and vision." In the activity, I can make use of things that can be seen everywhere in my life, so that children can explore, consciously inspire and guide, and make them interested in things and phenomena around them. Let children feel that "science is not far away, science is around us" and expand their thinking space.

Second, provide rich materials to open channels for children's development.

The "Outline" puts forward: "Provide rich and operable materials to provide conditions for every child to explore in various senses and ways. These materials imply the appropriate educational goals and contents that children can achieve through operation and use. These materials should arouse children's interest in inquiry, be open, have the possibility of multiple combinations, stimulate children to approach the materials, and be free to operate, change and combine in their own way. There should be a wide range of materials, so that children can study and explore in many different ways and make different discoveries. During the activity, I provided small baskets, building blocks, small glass bottles with lids, glass balls, foams, paper sculptures, etc. for children to perceive and explore, and let them observe the ups and downs of objects in the water. In the last link, I also prepared all kinds of auxiliary materials for children to look, think, play and move, to imagine and create, and to find out how to make sinking objects float through their own operations. How to make a floating object sink? In order to arouse children's interest in inquiry, many children think of many ways, such as: putting heavy objects on wooden blocks will float. Fill the empty bottle with water and then sink. And so on to expand children's thinking activities.

Third, stimulate interest in learning and guide children's development.

Interest is a child's teacher. The scientific field in the Outline puts forward the following goals: "Be interested in things and phenomena around you, have curiosity and thirst for knowledge;": Can use all kinds of senses, use hands and brain to explore problems; Can express and communicate the process and results of exploration in an appropriate way. " It can be seen that the value orientation in the field of science no longer focuses on the transmission of static knowledge, but on maintaining children's permanent curiosity and desire for knowledge, emphasizing that children actively observe, operate and experiment with various senses, and infer and draw conclusions from the results of exploration. For example, before the activity, I ask the children to tell which objects will sink and which objects will float, so that the children can guess first. Because children still don't understand some objects, most children say that building blocks and small glass bottles with lids are heavy, but I didn't stop them, but let the children operate and record them themselves. Draw a conclusion through experiments: what objects are floating on the water, (building blocks, plastic flowers, etc. Something is submerged in the water, (heavy things: keys, glass balls, etc. )

In the activity, I showed my findings as a learner, and with the help of this hidden demonstration, I inspired children to explore actively, let them explore the ups and downs of objects in the water themselves, and stimulate their interest in science.

The Teaching Plan of "Floating and Sinking" in the Activity Target of Kindergarten Class 2

1. Through experiments, we know that eggs will float in salt water.

2. Cultivate children's serious and meticulous study habits.

3. Cultivate children to like hands-on activities and have a strong interest in doing small scientific experiments.

4. Be able to boldly carry out practical activities and express your views in complete language.

5. Develop the flexibility of children's hand movements.

Teaching emphases and difficulties

Teaching focus:

Cultivate children's careful observation ability, like to do small scientific experiments and know that eggs will float in salt water.

Teaching difficulties:

Cultivate children's study habits of observing, thinking and thinking hard, and have certain exploration spirit and cooperation ability.

Activities to be prepared

Eggs, salt, water, courseware

Activity process

I. Activity Import

1. The teacher asked: Do you know anything that can float in water? (Children answer various answers)

2. Let the children put the prepared items (such as building blocks, locks, apples, stones, eggs, etc. ) put it in a transparent fish tank filled with clear water and observe which items float in the water. What sank in the water?

Two. teaching process

1. "I am a magician" The teacher mysteriously told the children that eggs can "swim" and float in the water. Add salt to fresh water (children don't know) while stirring, and the eggs slowly float.

2. Set doubts and let the children guess what the reason is.

The teacher told the children that adding salt to the water can increase the buoyancy of the water and the eggs will float slowly.

4. Children do experiments, put salt into water and stir it carefully. What happens when an egg sinks? Is it sinking or floating? Whose egg floats? Can eggs float without salt? how much is it? Ask him to share this method with his peers. The children are doing it carefully. Cultivate children's recording ability with pictures, charts and methods.

5. Then use the courseware, "Salt → Stir → Egg Float". Please observe carefully here.

6. Summary: Children organize eggs and water tanks, tell parents about the experimental methods, and share the feelings and sense of accomplishment of "playing with middle school".

Activity expansion

Things in children's homes will also melt, such as sugar and bean powder. Use the same method to see what effect it has. Observe different water temperatures with parents. Do eggs float at the same speed?

Teaching reflection

In the process of children doing experiments, a child secretly ordered salt water with his fingers and frowned and said it was salty. Your mouth is uncomfortable, said another child. Rinse your mouth quickly. Children are gaining direct experience and will help their partners. In the experiment, Bobo's egg floated and the water was accidentally spilled. Love the water's nature made him refill the water, and the egg sank again, adding salt and stirring. The operation process is relatively simple, and the child quickly succeeds in the experiment, and the process is positive and pleasant. Cultivating children's recording ability in activities, allowing children to learn learning methods in activities, and boldly expressing and giving feedback through pictures, charts and handwork are helpful to the development of personality. At the same time, the children exchanged and cooperated with each other in the experiment, learning from each other's strong points, thus ensuring the success of the experiment, and the children experienced the joy of cooperation and success. You can also prepare soluble substances commonly used by children: tea, soap, washing powder, etc. Conduct a comparative experiment. It should be noted that the water temperature of 20℃ is the appropriate temperature. If you do experiments in winter, you can add some hot water to help the salt dissolve quickly. In the days after class, some children suggested that people would float in salt water. Next to the children to discuss this problem. Finally, I left it to the children to solve it themselves. They can consult books, surf the Internet and ask their parents. Finally, the children had so many answers, which extended to the Dead Sea in the Middle East and the Dead Sea in Daying County, Sichuan Province, thus stimulating their strong interest in natural science and curiosity to explore scientific mysteries.

"Floating and Sinking" Teaching Plan for Kindergarten Class 3. Design Ideas

Last semester, the children in the big class had experienced the ups and downs of some objects (such as stones and snowflakes) in the water, so if the activity design only stays to let the children know and observe the ups and downs of various objects in the water, the children's interest in exploration will not be easy to go deep. And let the children explore with tasks, such as how to let the floating things sink and let the sinking things float, which can improve the enthusiasm of children to explore and help the development of children's thinking ability.

The intuitive actions of children's thinking in large classes gradually decrease, and the concrete visualization of thinking develops well. Therefore, activity design should not only provide children with the opportunity to think while operating, but also pay attention to cultivating the intentionality of thinking and cultivating children to predict (think) before operation. After the operation, let the children talk more and discuss more to promote the development of thinking in images.

Second, the activity objectives

1, knowledge: (1) Sensing the ups and downs of objects in water. (2) Learn to use a simple icon (↑↓) to record the results, indicating the floating and sinking of objects.

2. Skills: (1) Can complete the experiment in an orderly manner according to the teacher's requirements. (2) Be able to communicate, exchange and cooperate with peers and explore ways to adjust the ups and downs of objects.

3. Emotion: (1) Willing to participate in a small experiment to explore ups and downs. (2) initially form an interest in scientific activities.

Third, the focus of activities:

1, sensing the fluctuation of objects in water.

2. Learn to record the results with simple icons (↑↓), indicating the floating and sinking of objects.

Fourth, the difficulty of activities.

Explore ways to adjust the ups and downs of objects.

Verb (abbreviation of verb) activity preparation

1, each group has a washbasin filled with half a basin of water and a towel.

2. Assemble a full and empty mineral water bottle, plasticine, stones, snowflakes, leaves and other small items.

Everyone has a recording paper and a pen.

Activity process of intransitive verbs:

1. Know the experimental materials Teacher: There are many articles in our class today. They are hiding under your chairs. Find out who it is.

Yang: Is it a key, a piece of wood or a glass ball?

2. Experiment: Sinking and Floating

Teacher's demonstration: The teacher takes a snowflake and asks the children to guess: What will happen if this building block is put in water? Record the guessing results on the record sheet, let the children guess the prepared materials, and record the guessing results on the record sheet.

Teacher's instruction: Guess what happens when snowflakes are put in water? Each of you has a record paper and records your guess results on it. If you guess what snowflakes are floating? Put a ↑ (vertical bar with a small hat on it) in this column. If you think it's sinking, make a "↓" (vertical bar with a small hat on it).

② Experiment: Record the experimental results on the recording paper.

Children practice according to their own wishes, and teachers pay attention to observation records and give targeted guidance; Pay attention to the performance of young children.

Will the key float or sink? Right? Are other things the same as we guessed? The teacher prepared water. Let's try these things there. After the test, record the experimental results in the column of "Little Hands".

(3) Comparing the two results according to the record table, we focus on the exchange of the final results.

Q: "Is there a difference between the test result and the guess result?"

Summary: (Show tables and objects and demonstrate) Through experiments, we know what floats up ... what sinks down ...,

Seven, improve the experiment

(A) How to make floating things sink

1, Teacher: Little friend, now our baby bottle is floating on the water, but he and baby stone are good friends. They want to play games in the water together. Let's help them, ok? Help the baby bottle sink.

2. Children try. (If the child can't figure out a way at once, you can give the child 1-2 minutes to try and discuss. If there are still no children to figure out a way, then guide them. )

3. Teacher: Little friend, the same baby bottle floats on the water when it is not filled with water, but sinks when it is filled with water. Why?

4. Teacher's summary: When water is not filled, the bottle is very light and floats on it; After being filled with water, the baby bottle became heavy, so it sank.

(2) How to make sinking things float?

1, Teacher: Little friend, we just let the baby bottle play with the baby stone. They had a good time. However, there is one more thing. The baby needs your help. Look, little plasticine and little leaves are good friends. They really want to float on the water together. Let's help them!

2. Children try. (If the child can't figure out a way at once, you can give the child 1-2 minutes to try and discuss. If there are still no children to figure out a way, then guide them. )

3. Teacher: Now the plasticine baby can play with the leaf baby. He's so happy. But he has a question for the children, "My weight hasn't changed. When I become a ball, I will sink to the bottom of the water. When I am shaped like a boat, I will float. Why? "

4, young: ... (This question is more difficult, you can let the children think, communicate and discuss 1-2 minutes first. If the child can't answer by then, the teacher will re-guide. )

5. Teacher's summary: When the plasticine baby is spherical.

Eight. Expansion of activities

1, Teacher: Children, teacher, here is another item. What's the matter, children? Guess-is the baby heavy or floating in the water?

2. Young: ...

3. Teacher's summary: The teacher doesn't know whether the baby will sink or float. Actually, son, there are still many things in our lives. We don't know whether they will sink or float in the water. After the children go back, they can explore with their parents what other things around us sink or float in the water.

The teaching plan "Floating and Sinking" for large classes in kindergarten 4 Activity objectives:

1, let children feel the ups and downs of objects in water and learn to use simple icons to represent the ups and downs of objects.

2. Explore ways to adjust the ups and downs of objects.

3. Cultivate children's creative thinking and develop their spirit of exploring knowledge.

Activity preparation:

1, various test materials (table tennis, building blocks, empty bottles, keys, plasticine, small stones, nails, leaves, small bowls, magnets, pens and paper).

2. Every four children share a console, another sink and a tray.

Emphasis and difficulty: explore and discover different methods to make objects sink or float.

Activity flow:

First, create a scene.

Children listen to music and enter the laboratory, and see all kinds of experimental materials to stimulate their desire to operate.

Second, children try

(1) The teacher asked a tentative question: What will you find if you put these objects into the water?

1, try it, kid

2. It is concluded that some objects float (float) on the water surface and some objects fall (sink) into the water.

3. Teacher's summary (demonstration courseware): The phenomenon of table tennis, building blocks and empty bottles in the water is called floating, and the phenomenon of keys, plasticine, pebbles and nails in the water is called sinking.

(2) The teacher asked a question: If the upward arrow indicates floating, the downward arrow indicates sinking. What symbols should these experimental materials be represented by? Plastic, paper, comb, toothbrush, battery, pencil, knife and eraser.

Each group of children tries to guess, and draws the guess results of each material sinking or floating on paper.

The teacher summarizes (demonstrates the courseware) to verify whether the children's guess is correct. Different opinions (like an object, some children think it is heavy and some children think it is floating) are verified by experiments and unified.

(3) The teacher asked a question: How to make a floating object sink? Let the weight float?

1, try it, kid

2. Draw a conclusion: Fill the empty bottle with water and tie the pencil to the stone. Can make empty bottles and building blocks float on the sink; Squeeze plasticine into the boat, nail the building blocks, and let the plasticine and nails that have sunk into the water float up.

The teacher encourages the children to try different materials and methods.

(4) Teachers ask exploratory questions:

1. Story: Xiaoming was playing football in the Woods and accidentally kicked the ball into a hole in the tree. The hole in the tree is too deep for Xiao Ming to reach. How anxious he is. Who can help him think of a way?

The child tried to answer: water the tree hole and the ball will float.

The teacher demonstrates the courseware and verifies the answers.

There is a pile of wheat mixed with bran. How to separate wheat bran from wheat grains as soon as possible?

Children try to answer: put them in water, what floats on them is wheat bran, and what sinks to the end is wheat grains.

The teacher demonstrates the courseware and verifies the answers.

(5) What are the applications of ups and downs in our production and life?

Children try to answer: the application of lifebuoy, the application of rice washing and cooking, and the application in ships and submarines.

Teacher summary (demonstration courseware):

The ups and downs are closely related to people's production and life. It is widely used in industry, agriculture, national defense and other fields, and can do many things for mankind.

Activity expansion:

In daily life, what other objects are made by using the principle of ups and downs?

The teaching plan "Floating and Sinking" for kindergarten large classes 5 Activity objectives:

1. Know what is heavy and what is floating in the water in the exploration activities. And you can record the results with ↓, ↑, indicating ups and downs.

2. On the basis of sensing the ups and downs of objects in water, try to explore different ways to change the ups and downs of objects. 3. Be able to listen attentively to other people's speeches and boldly tell your own operation process and results.

Activity preparation:

1. Teaching experimental materials: all kinds of objects that can sink and float (toys, small pieces of wood, spoons, etc. ), 7 large containers, record sheets, etc.

2. Scientific terms and vocabulary: sinking and floating.

Activity flow:

First, guess the activity:

1, Teacher: There are many articles in our class today. These articles want to swim in the water. Guess what will happen? (Show sink and float cards) 2. Teacher: You said that some will sink and some will float. I don't know, so let's throw the toys in.

3. Let the children boldly guess the ups and downs of the rest of the baby.

Second, children's operational activities: perceive the phenomenon of "sinking" and "floating".

1, the first experiment: Do children put things into the water to see if the result is consistent with their own guess? .

2. First record: record the results of conjecture and experiment.

3. Communication: Children exchange their first guesses and experimental results with each other to explore whether their guesses and experimental results are consistent.

Third, explore the use of different materials to float sinking objects.

1, these things baby, some are heavy, some are floating in the water. Now the teacher will invite you to play and use your little brain. Is there any way to make what was originally submerged float and let what floated sink to the bottom? Tell us your method when you have fun.

2. Children operate to change the ups and downs of objects and encourage children to try different materials and methods. 3. What method do you use to make the sinking things float? Did it work?

Child: The heavy things will sink when supported by the heavy things, and will float when supported by the floating things. The teacher summed up: floating things can help heavy things float; Sinking things can help floating things sink, and it is related to the weight of the object. 4. Experience migrating water has many magical powers, but if the water is too big, it will also bring us harm. When there is a flood (picture), everything around us will sink into the water, and so will our people. At this time, what can we do to save ourselves from sinking? Life buoy, footbath, wood, boat, etc. V. conclusion.

Scientists are very clever. They used the magical power of water to invent boats and submarines, which can let us walk around in the water. When our children grow up, they can also invent things that sink and float in the water.

Design background of activity 6 of "floating and sinking" teaching plan in kindergarten.

The new "Outline" points out that science education should be closely linked with children's real life, and the things and phenomena around them should be taken as the objects of scientific inquiry. Water is indispensable in our daily life, and we can't live without water every day. Because water is closely related to our life, children naturally like to play with water because they have been in contact with it for a long time. In the process of playing with water, many interesting and novel phenomena were discovered. Therefore, I chose the scientific activity of ups and downs of objects in water.

moving target

Objective 1: I am interested in scientific activities and can actively explore and find answers.

Goal 2: Understand the ups and downs of objects.

Goal 3: Cultivate children's ability of unity and cooperation.

Teaching emphases and difficulties

Teaching emphasis: understanding the ups and downs of objects.

Teaching difficulties: floating and sinking, sinking and floating.

Activities to be prepared

6 big pots, 12 basket, some paper, dry wood blocks, stones, nails, plastic cups, leaves, table tennis, solid balls and coins.

Activity process (it is not necessary to record all the conversations and activities between teachers and students in detail, but it is necessary to clearly reproduce the main links of the activity, that is, the beginning link, the basic link, the end link and the extension link. Note: Emphasis is placed on the basic links)

One: Please guess which of these things will float and which will sink. (Set suspense to arouse children's curiosity)

Two: operation, please put the things on the table in the basin and see if the result is what you think.

Three: Let the children put the heavy and floating objects in two baskets respectively, and then tell the children and teachers in other groups which ones are heavy and which ones are floating. Paper, dry blocks, plastic cups, leaves and ping-pong balls are floating, while stones, nails, solid balls and coins are sinking.

Four: Why are some heavy and some floating?

Please use the contents of the basket to think about how to make the floating things sink and the sinking things float (press the paper with stones and put coins in plastic cups). )

Six: Let the children go home and find out with their parents what will sink to the bottom and what will float to the surface.

Teaching reflection

The activity design of "ups and downs" comes from a sudden discovery of children. The activities closely focus on the interesting phenomenon of "ups and downs" to satisfy children's curiosity and stimulate their desire to explore. This activity always takes children as the main body, allowing children to guess and judge the ups and downs of objects by using existing experience, so as to actively construct knowledge and experience. On this basis, children can verify their guesses through games, explore the causes of the ups and downs of objects, gain knowledge and experience related to the ups and downs of objects, and change the ups and downs of objects through their own hands-on operations. In this activity, I provided rich materials for the children and paved the way for their development. Activities can stimulate children's interest in learning and guide their development.

Teaching reflection

The whole activity can be carried out according to my process, and the goal of the activity is basically achieved. The children are very interested and willing to participate in the experimental activities, but there are still some shortcomings. First, I still don't have a good grasp of the ability of the children in the class. When I took the lead in introducing them, I just told the children the name of the arrow, but I didn't teach drawing. Second, the requirements are not detailed enough before the child operates. Third, the preparation materials are not sufficient, because fruits and vegetables have not been tested before, which leads to the floating of fruits and vegetables during the children's experiment and no sinking of fruits and vegetables; In addition, it is not enough to explain the ups and downs of fruits and vegetables.

Children's Encyclopedia: Objects submerged in liquid (or gas) are pushed upward by liquid (or gas).
