Teaching plan for large classes in kindergarten "Oil and Water" 1 Activity objective:
1. Interested in scientific exploration activities by sensing the phenomenon of dumping and separation of oil and water after stirring.
2. Understand the related phenomena of oil-water separation in life and experience the application of scientific knowledge in life.
Activity preparation:
Everyone has a bottle of water, a bottle of oil, a chopstick and a picture drawn with an oil pastel. Pigment water of various colors; Seagull headdress; Give some examples
Activity flow:
First, scene import
1, Little Seagull: Little friend, there was an oil spill on the sea yesterday, and the oil spill was left in the sea. At the same time, show oil and water to guide children to observe: the color of oil and water, their * * * sex-fluidity.
2. Show the pictures and let the students guess. When the oil reaches the water surface, the following phenomena will appear: ① the oil is above the water surface; ② Oil is underwater; ③ Oil and water are mixed together.
Second, perceive the phenomenon of oil-water separation after mutual dumping.
1, please try: What happens when oil is poured into water or water becomes oil?
2, children's operation, teacher guidance
3. Communication: What do you pour? What did you find?
4. Show the diagram and sum it up in a seagull's tone: whether oil is poured into water or water is poured into oil, oil is above and water is below, they are separated and will not be mixed. Children, did you guess right?
Thirdly, the phenomenon of oil-water separation after stirring is perceived through operation.
1, Little Seagull: But there are often strong winds and waves at sea. When the wind and waves come, won't oil and water mix together? Let the children guess.
2. Two children demonstrate that oil and water are stirred vigorously, and the teacher guides the children to observe the stirring phenomenon and stop it. What did you find? 3. Please ask all the children to operate: You also have a try, right? 4. Show the chart and sum it up in a seagull's tone: stir hard with chopsticks (just like when the waves come), and the oil and water are still separated and will not mix. Did you guess right this time?
5. Little seagull: The oil floating on the water has polluted the seawater where we live. Now my uncles and aunts who protect the marine environment have salvaged all the oil and the sea water has become clean again. Now I should go home!
Fourth, extend the children to play "oil-water separation painting" and think about why paint water will not be mixed with oil pastels. Feel the application of oil-water separation in life.
The goal of "Oil-water" 2 activity in kindergarten large class teaching plan;
1. Understanding of oil-water separation in operation.
2. Explore the method of oil-water fusion boldly, and learn to record the experimental results initially.
3. Willing to actively explore and carefully observe and compare.
4. In the activities, guide children to observe and discover phenomena carefully, and study scientific phenomena with empirical evidence.
5. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
Activity preparation:
Water, peanut oil, disposable transparent cup, rag, recording paper, pen, chopsticks, hot water, detergent.
Activity flow:
First observe the oil and water, and use various senses to initially perceive its characteristics.
Distinguish oil from water by guiding children to see colors and smells.
1. You all have two cups in front of you. What's in the cup?
2. What's in the cup? how do you know
3. Summary: Yes, this is a glass of water and a glass of oil.
Second, experiment: observe the phenomenon of oil-water separation.
1. Guess what happens when you pour oil into water.
2. Children experiment and observe.
What secret did you find when you poured the oil into the water? (Note: Be careful when you pour it. Don't fall outside. If spilled, clean it with a rag in time. )
3. Summary: After oil and water are poured together, they are divided into two layers. Oil and water are separated, with oil always on top and water always below.
Third, explore whether different materials can blend oil and water.
1. Is there any good way to blend them together?
2. Show three materials and guess collectively.
Here are chopsticks, hot water and detergent. Do you think these things can make oil and water blend together? (The teacher takes notes)
3. Children observe the experiment and record the experimental results on paper. (Remind children to operate and record one, so as not to forget the experimental results)
4. Exchange experimental results
Summary: It turns out that detergent can help oil and water blend together and become a white liquid.
Fourth, contact with real life.
1. Besides detergent, what else can make oil and water blend together? (Children answer according to previous experience)
2. Watch the video (detergent, laundry detergent to remove oil stains)
3. Summary: It turns out that detergent, washing powder, laundry detergent and other washing products can integrate oil and water and help us clean oil stains on clothes and hands in life!
Activity reflection:
Oil and water are common things in daily life. What happens when oil and water are mixed together? This is a phenomenon that often appears in life but is not paid much attention to. I seize this phenomenon in order to stimulate children's interest in exploration through observation, recording and experimental operation. The whole activity is closely linked, slow and stable. In the process of activities, teachers guide children to make bold guesses and adhere to the principle of exploring and discovering themselves, cultivate children's ability to explore actively, let children realize true knowledge in practice and discover the mystery of "oil and water" through careful observation. It also cultivates the scientific attitude that children dare to question and be willing to guess. Activities to achieve educational goals.
The goal of teaching plan "oil and water" in kindergarten class 3 activities
Cognitive goal: children perceive the separation phenomenon after oil-water mixing through experimental operation.
Emotional goal: to cultivate children to actively participate in scientific experiments, experience the fun of scientific exploration, and sprout interest in science.
Important and difficult
1, children know that the ratio of oil to water is different through hands-on operation, and they can record it in the right way;
2. Children can operate the experiment correctly and understand the scientific truth.
Activities to be prepared
1, water, peanut oil, towel, stirring stick, porcelain dish, rag, whiteboard pen, several transparent cups marked with yellow and blue,
2, the experimental record sheet, pen,
Activity process
First of all, the magical import.
Watch the magic show to stimulate children's interest in learning.
Teacher: Children, today the teacher is going to do a magic trick for the children. Be sure to keep your eyes open and look carefully!
First, I took out the China dish. The teacher painted on the dish with a magic pen. The teacher said while drawing (small black beans swimming in the water, slender tail, round head) children guessed. The teacher continued to draw two or three tadpoles. After painting, pour the water into the plate, and the tadpoles will separate from the plate and float. Do the children want to know why tadpoles float on the water? The teacher takes the child to reveal the secret!
Second, the experimental operation.
Show experimental materials and teaching AIDS first, and children can make bold guesses.
1, indicating water and oil. Children can draw conclusions from colors and smells through careful observation and speculation:
Water is a colorless, odorless, transparent and flowing liquid.
Oil is a colored, odorous and flowing liquid.
2, show oil and water, let children guess freely. What will happen if these two flowing liquids are mixed together? Where is the oil in the water? Teachers show teaching AIDS, children make bold guesses, and teachers record children's guesses.
Oil is on water, oil is under water, and oil is in the middle of water.
(2) Children operate the experiment for the first time.
1. The teacher introduces the homework materials and puts forward the homework requirements.
The blue cup is filled with water, and the yellow cup is filled with oil.
Teachers talk about requirements while operating:
(1), add oil to the transparent glass marked with blue.
(2) Stir vigorously with a small stick, and observe the phenomenon carefully after stopping.
(3) If you accidentally drop oil on the operation panel or knock over the operation materials, please wipe it with a rag on the table.
2, children operate experiments independently, and teachers tour to guide.
After the operation, the child found the oil on the water.
3. Teacher's summary: After the operation, we found that after adding oil to the water, the oil was on the water surface.
(3), children's second experiment, show the recorded results.
We added oil to the water just now. This time, we conducted another experiment, adding water to the oil, and then carefully observing the position of the oil in the water after stirring. This time we're going to record it with a record sheet.
1, teach children to know the experimental record sheet and explain the recording rules.
Blue stands for water and yellow stands for oil. After the experiment, observe carefully to see the position of oil in the water, and mark it with √ on the diagram.
2, children operate independently, and teachers guide them.
3. Display and summarize the recorded results.
The teacher concluded: Because the oil-water ratio is different. Oil is lighter than water, so whether you pour water into oil or oil into water, oil floats on water and water is under oil.
Attached to the experimental record sheet:
4. Reveal the secret: Now children know why the tadpoles drawn by the teacher float on the water. Because the teacher's magic pen is a whiteboard pen. Whiteboard pen contains stripping agent, which is "oily". These "oily" stripping agents will separate when exposed to water. Oil is lighter than water, so tadpoles will climb to the surface. )
Third, expand and extend.
1, the teacher instructed the children to make a painting of "oil-water separation" with crayons and gouache pigments and observe the wonders.
2. After the children go home, they are doing an experiment of "oil-water separation" with their parents to consolidate their existing experience.
Activity summary
In this class, the children behave very well. They did experiments by themselves one by one, and got a preliminary understanding of the principle of oil-water separation from the experiments. Scientific exploration is infinite. In future activities, the teacher will take you to explore the mysteries of science. Everybody, keep cheering!

Activity process
First, import
Teacher: Today, the teacher brought you many little guests to play games with you. You want to know who they are?
(Thinking) Well, let's go and see who's there. (The teacher introduces the experimental materials)
Second, let the children begin to operate, pour blue and black pen water into a glass of water and observe what changes between them.
Teacher: Before doing the experiment, the teacher has requirements. Please listen carefully. Please pour the blue and black pen water into a glass of water and observe it carefully. What will happen to them?
1. Q: What did you find? (They melt together and become black water)
Teacher: Is that what you said? Let's verify it together. (The teacher verifies the experimental results)
Summary: You observed it carefully. Yes, blue and black pen water is poured into the water, and they melt together and become black water. This means that they can blend together. ) explain the meaning of melting. When one object is combined with another, they can be dissolved. If you can't combine, separate. )
Third, let the children think about it. What happens when oil and water are poured together?
Teacher: Guess and think. What secret will you find when you pour oil into melted water? I don't know. Now please pour the oil into the melted water and observe it carefully. What's changed between them?
Question: 1. Can oil and water blend together?
2. Why?
Teacher: Is it true? Then let's see if you found this. (The teacher verifies the experimental results again)
Summary: Because the specific gravity of oil and water is different. Whether you pour water or oil first, the oil floats on top of the water and the water is below the oil. Explain that oil and water cannot be together, but are separated.
Yes
Fourth, by extension, let children play with oil-water separation painting and imagine why pigment water will not be mixed with oil pastels.
Conclusion: Your performance is wonderful. What other compatible objects are there in our life? What are miscible? Let's go outside and have a look!
