1 the design intention and thinking of the teaching plan of middle school science test paper;
Children in Chen Chen brought back a unique "oiled paper umbrella". It looks good in the classroom. The children asked, "What kind of umbrella is this?" This activity was designed to satisfy children's curiosity. Guide children to understand the production and characteristics of different umbrellas and expand their knowledge.
Applicable object:
Middle class children
Activity suggestion:
Encourage parents to collect more oil-paper umbrellas for their children to enjoy.
Activity objectives:
1, let children know the difference between oil-paper umbrellas and ordinary umbrellas through activities.
2. You should know that oil-paper umbrella is the inheritance of traditional art. ..
3. Germinate the feelings of loving science and nature.
4. Experience the sense of accomplishment in solving problems.
5. Actively participate in exploration activities, sprout curiosity and experience success and happiness.
Activity preparation:
1. Collect all kinds of oiled paper umbrellas.
2. CD about oil-paper umbrella.
3. Stick the collected pictures and written materials on the wall for children to observe and appreciate.
Activity flow:
1, the teacher shows the oiled paper umbrella and the ordinary umbrella, so that children can freely observe and discuss the differences between the two umbrellas.
2. The teacher summarizes the results of the children's discussion.
3. Let children watch the process of making CDs with oil-paper umbrellas, and let them watch with questions.
4. Guide children to exchange what they see with each other and talk about the difference between oil-paper umbrellas and ordinary umbrellas. What are their characteristics?
5. Draw a beautiful oil-paper umbrella by yourself.
Activity evaluation:
Children are very interested in the beautiful patterns of oil-paper umbrellas, and they also know that oil-paper umbrellas are mainly colored with cotton paper, which is a manual production process, while ordinary umbrellas are mechanical production processes. The feeling of loving nature and the spirit of daring to explore have sprouted.
Teaching reflection:
The beginning of a scientific activity should come from children's existing experience, and the end of a scientific activity is not really the end. Let children have the possibility of further exploration and become the beginning of gaining experience. Children are the masters of learning, so our teachers should try their best to create various learning environments, so that children can see, listen, speak and think with their brains, explore wholeheartedly and actively, and give them free space to show. Let children gain knowledge and experience in games and happiness.
The second design intention of teaching plan and reflection on science examination papers in middle schools
First of all, before the activity, I collected commonly used papers with my children and put them in the science area, so that the children could fold boats and flowers, and play games with their own homemade flowers according to the monthly theme activity "Umbrella Flowers Bloom". In the game, the children are very interested in "paper flowers" made of different materials and ask many questions, so I preset the activity of "absorbent paper" according to the theme of "paper dolls" and the children's interest in "playing with paper in water". In the whole activity, I started from exploring the water absorption of paper, creating situations and asking questions, which triggered children's speculation and thinking. Provide simple and interesting experimental materials for children, suitable for them to explore, and verify, share and expand through experiments. Let children experience the process of inquiry and develop their initial inquiry ability. I also train children to observe patiently and carefully, and record what happens in the experiment. Activities focus on the process of inquiry and cultivate inquiry ability.
moving target
1. Explore the changes of different paper in water and feel the water absorption of paper.
2. Through experimental operation, observation and comparison, we know that different papers have different water absorbability.
3. Experience the fun brought by scientific inquiry activities and learn to cooperate in groups.
Important and difficult
1. Activity focus: Feel the water absorption of paper through experiments.
2. Activity difficulty: I know that different materials of paper have different water absorption.
Activities to be prepared
1. Experience preparation: The child has collected various papers in life in advance and has a certain perceptual experience.
2. Material preparation: one display board of four kinds of paper, six large record sheets, six small record sheets, several (napkin dolls, newspaper dolls, paper dolls, milk box paper dolls), six towels, six transparent boxes, ppt and plates.
6. Mask paper, aluminum foil paper and 6 pens.
Activity process
First, the dialogue leads to the theme.
Teacher: Some time ago, I asked the children to go back and collect all kinds of paper. Let's see what paper we have here. (napkins, newspapers, drawing paper, milk carton paper) Where can I find these papers? (Children actively answer)
Teacher: These papers are very common in our life. I made four paper dolls from these four kinds of paper. Look! Today, the paper doll will become a diver.
Second, experimental operation, sharing and communication
1. The question raises doubts.
Teacher: Please guess which paper doll can dive? Why? (Let a child take notes) Is it really as you guessed? Then let the paper dolls try it!
experimentalize
(1) Description: Each table has a plastic box filled with water, paper dolls made of different materials, and a record sheet.
(2) Operation requirements: 6 people cooperate, put paper dolls of different materials into the water at the same time, then carefully observe who can dive best, and then make a record on the record sheet.
(3) Children's operation and teachers' itinerant guidance.
3. Share communication, verify and reach a consensus.
Teacher: Which paper dolls can "dive"? How do they change in water?
Summary: It turns out that different papers have different water absorption capacity. Napkin dolls are the easiest to absorb water and dive. Milk carton paper is the most difficult to absorb water and the least diving. Newspapers and drawing paper can also absorb water, but for a longer time.
Teacher: After listening to it, the paper doll quarreled about whether it could absorb water. Paper dolls that can absorb water think they have great water absorption capacity, while paper dolls that can't absorb water think they have great water absorption capacity. What are we doing? They quarreled. I have a good idea. Today, I also brought two very special kinds of paper (mask paper and aluminum foil paper). They will understand after reading this!
4. Joint verification between teachers and children
1: Showing two different kinds of paper (mask paper and aluminum foil paper) makes children think: What paper are they? Let's see what they can do. What's the use? Mask paper can make our parents beautiful, and aluminum foil paper mother can make us delicious egg tarts in the kitchen. ) 2. The teacher operates the children to observe carefully and speak boldly.
3. Summary: In fact, whether it is paper with strong water absorption or paper with weak water absorption, they all have their own advantages, which brings a lot of convenience to our lives. After listening to this, we paper dolls happily play games hand in hand!
Third, the extension of activities.
Please go home and collect more papers made of different materials, make them into your favorite paper flowers, then put them in flowerpots for experiments, explore the water absorption situation by yourself, and make records, and then invite children to share their experimental results in the "Morning Sound" activity.
Activity summary
After this class, I feel that children are very interested in this activity. Children like to explore and learn to observe and record. Therefore, the design of this activity fully embodies the spirit of discovery and exploration in the scientific field, and the theme is closely related to life. Through the operation, the children's interest and enthusiasm in participating in scientific activities have been improved, and they have gained experience and a sense of accomplishment. In future activities, we should provide children with rich operational materials so that every child can operate and fall in love with scientific activities.
Teaching plans and reflections on scientific papers in middle schools Chapter III Activity objectives:
1, let the children find that the wax paper cup is watertight through exploration, and know that the disposable paper cup is a sanitary and convenient drinking utensil.
2. Stimulate children's interest in exploring things around them.
3. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
4. Willing to try boldly and share experiences with peers.
5. Fully experience "science is just around the corner" and generate interest in discovering, exploring and communicating in life.
Activity preparation:
1, some disposable paper cups, and some other kinds of paper (newsprint, horse manure paper, etc.). ). Record card, pen.
2. Each table has a pot of water, a small bucket and a rag.
Activity flow:
First, explore in groups to understand the different reactions of different paper cups filled with water:
1. Let children pour water into paper cups and observe the changes of water in various paper cups. It is found that some cups are leaking and some are not.
2. Let the children pour the same amount of water into each cup, and observe and record the water leakage of different cups.
3. Question: Are all the paper cups leaking? Which paper cup leaks quickly? What kind of paper cups will leak slowly? What kind of paper cup won't leak?
Show the results of each group's observation records and summarize them.
Second, guide children to observe different paper cups and explore the reasons why beverage paper cups don't leak.
1. Organize children to observe, compare and discuss with each other: Why do some paper cups not leak and some paper cups leak?
2. Inspire children to discover that a layer of wax is coated in the watertight paper cup through exploration.
Third, organize children to discuss the use of disposable paper cups.
1, Question: Where have you seen this kind of paper cup? What are their uses? (Let the children communicate with each other and answer)
2, the teacher concluded, guide children to know that this is a common disposable paper cup, which is convenient to manufacture, sanitary and cheap, so it is becoming more and more popular in daily life.
Fourth, activity extension.
Instruct children to do experiments, coat a layer of wax on ordinary paper and check the degree of water leakage.
Activity reflection:
The new "Outline" points out that science education for children is a scientific enlightenment education, which focuses on stimulating children's cognitive interest and exploration desire, creating conditions for children as much as possible, using various senses, using hands and brains, exploring problems, solving problems and experiencing the fun of discovery.
The fourth chapter is the teaching plan of middle school scientific papers and the goal of reflection activities.
1. Explore various ways to make paper stand up and develop innovative thinking.
2. Cultivate children's interest in exploring science.
3. Willing to try boldly and share experiences with peers.
4. Make children interested in exploring natural phenomena.
Activities to be prepared
1. Some rubber bands, building blocks, plasticine, paper clips, chopsticks, cups and white paper.
Everyone has a record sheet.
Activity process
1. Try to make the paper stand on the table, which can't stimulate children's hands-on interest.
(1) Introduce activists: The teacher wants this paper to stand up. Do you think it can stand up?
(2) Organize children's discussion: What can be done to make the paper stand up?
The children tried to make the paper stand up without any auxiliary materials.
(1) Inspire children to make paper stand up without any auxiliary materials.
(2) Children explain and demonstrate their own methods and communicate with their peers.
3. Children should not fold the paper, but try to make the paper stand up with the help of materials.
(1) The teacher introduced the information provided.
(2) The teacher introduced the recording method of the recording form.
(3) Children's operation: The teacher focuses on observing children's operation and encourages children to use the materials provided by the teacher to help the paper stand up on the table to see who uses more methods, which is different from others.
(4) Children explain and demonstrate their own methods and communicate with their peers.
4. Expanding activities: provide papers with different thicknesses and hardness, so that children can further explore ways to make papers stand up.
Teaching reflection:
After the whole activity, I feel that my thinking is not very clear. I don't have a good summary of the various ways that children make paper stand up. Maybe I didn't classify the possible methods when I designed the lesson plan in advance, and I didn't consider them thoroughly enough, which led to the unclear thinking in class. During the activity, I didn't explain the concept of "how paper stands up" to my children. I thought it over beforehand, the paper should stand up from the ground, and it is suspended on the ground, not standing up. However, during the activity, I saw some children propping up the paper with building blocks, and the paper was lying on the building blocks. After seeing this phenomenon, I still didn't ask this question. When designing the lesson plan, I am considering whether to provide tools or operate them by hand first. After listening to the tutor's comments, the problem was solved.
The teaching plan of middle school scientific papers and the activity goal of reflection chapter five;
1. Understand the water absorption characteristics of paper, and feel that different materials of paper have different water absorption.
2. Willing to operate and interested in experiments.
Activity preparation: 2 handmade paper flowers per person, rice paper flowers per person 1, fruit bowls, pots, water, record sheets, colored pens, etc.
Activity flow:
First, import activities to stimulate interest in inquiry
1. Today, I brought you some beautiful flowers. Find yourself a favorite little flower and sit next to it. Are these flowers the same as what we usually see? What is the difference? This is a flower made of paper.
Can these paper flowers bloom like real flowers? Children discussion
The teacher demonstrated how to turn flowers into buds.
What will happen if we put these buds in water? (Children speak boldly) (Children turn flowers into buds)
Second, operational awareness, exchange and discussion.
1, children's operation, teachers' tour guidance
What did you observe? When the bud is put into the water, the petals will slowly open and the paper flowers will open.
2. The teacher asked: Why do buds bloom slowly when put in water?
Let the children express their opinions and let the teachers compare.
3. Summary: It turned out that the paper baby washed the water into its body and the flowers opened.
This is because paper absorbs water. We discovered the first little secret of paper.
Third, compare the experiments and improve the experience.
1. Just now we found that flower buds made of colored handmade paper can bloom in water. The teacher also prepared rice paper. If you put these two different kinds of paper into the water at the same time, which one do you think will bloom first? Preschool guess
2, children re-operation: making flower buds, to be honest, at the beginning, all children put two flowers in the water at the same time.
3, children's operation, record the results, teachers tour guidance.
4, collective communication, verify the experimental results, correct some children's wrong prediction results.
Fourth, observe the experimental results and discuss: Why do the buds made of rice paper bloom quickly? Children telling
Summary: Xuan paper has strong water absorption and can absorb water into the body quickly, so paper flowers made of Xuan paper will bloom soon. Compared with Xuan paper, colored handmade paper has poor water absorption, so the water baby will slowly enter its body, so the flowers made of colored handmade paper will slowly open.
This is because different papers have different water absorption. We discovered the second secret of paper.
The expansion of verb (verb's abbreviation);
The teacher asked: What happens to flower buds made of different kinds of paper in water? We continue to experiment in our corner.
Reflections on the Open Course of "Open Paper Flowers"
"Paper Flowers Bloom" is a scientific exploration activity that I teach after class. The goal of the activity is to let children know the water absorption of paper first, and then understand that different materials of paper have different water absorption. Before class, I made sufficient preparation of materials and did a lot of experiments. During the activity, my children and I explored and studied together and actively participated in the activity. Children's choice of materials is also very directional. When teachers show all kinds of materials, they often hear "this is the paper we drew", "this is the paper I practiced writing" and "this can be used for origami" ... For the preparation of materials, I left homework for my children and collected it carefully after I got home. My parents also participated. Children share their collection results with their peers, and they find that there are so many things in life. Feel the diversity of paper, children actively discuss in the experimental operation, which is verified by experiments, and know how to look at things scientifically, and can't replace the experimental results with subjective opinions. Perceive the experience in the activity and be able to clearly state the conclusion. The overall situation of the children in the whole activity is very good, they are actively involved and have a strong interest.
Some problems were also found in the activity, which need to be paid attention to and improved in the future work: First, the explanation language should be concise, accurate and instructive. The second is to increase the content of exploration so that children can learn to complete their works independently step by step. Individual children are eager to find the answer, which is easy to appear in the operation process. In this link, the teacher did not make sufficient preparation and guidance, so that individual groups of children had to stop to clean up the stagnant water. In future activities, teachers should be fully prepared for the activities.
Generally speaking, I am satisfied with the effect of this activity class, and I hope I can go to work in the next level.
Teaching plan of middle school scientific papers and the goal of reflection activities Chapter VI
1. Let the children know that the "paper ball rebound" is caused by air flow through the game.
2. Cultivate children to pay attention to scientific phenomena in their surrounding lives and have a desire to actively explore.
3, can take the initiative to communicate their findings with peers, stimulate the desire to further explore things change.
4. Pay attention to listening to and respecting peers' speeches in communication activities.
Activities to be prepared
1, several flasks and some paper balls.
2. Books (reference room).
Activity process
First, play the game of "blowing paper balls" to lead to the topic.
1, Teacher: Children, the teacher has many small paper balls. Do you want to play the game of "blowing paper balls"?
We each take a paper ball and blow it. What did you find? (children operate the paper blowing group and draw the conclusion that the paper blowing group runs forward. )
Second, the teacher asks further questions, shows the flask, and the child operates it again.
1, Discussion: Will the paper ball run forward forever? (Conclusion: If there is an obstacle ahead, the paper ball will stay in its original position. )
2, children with narrow neck bottle and small paper for the second operation.
Teacher: What do you think will happen if you put a small paper ball on the bottle mouth and blow it hard? Please try again.
Third, establish the phenomenon of "paper ball rebound".
Teacher: Do you know the answer? Will the little paper ball run forward? Will it run into the bottle? Conclusion: If you don't tilt the bottle, the small paper ball will never blow into the bottle. )
Fourth, query information to find the secret of paper ball rebound.
Teacher: What is the reason? Shall we go to find the information together?
Extended activity
Teacher: Is this little experiment interesting? Let's draw a chart and tell all the children, shall we?
Teaching reflection:
Teaching method is essentially an incentive means. Teaching method and questioning method stimulate hearing, demonstration method and viewing method stimulate vision, practice method and game method comprehensively stimulate various senses ... Therefore, the key to the success of teaching method is to see whether it can give full play to its due stimulating role.

Activity reflection:
For children, the best way to learn is to learn in the most direct experience and find out by doing. In this activity. I chose "paper", the most common material in life, and made an operation experiment for my children, transforming the science of force into a game that children can operate by themselves, relying on children to be familiar with intuitive materials. Let children feel amazing scientific phenomena in life in challenging activities, and strive to make children feel happy and gain wisdom in inquiry games.

Activity flow:
First, know the paper teacher: children, there are many paper babies coming to play games with us today. Do you want to play with them? Ok, now let's take out the small laundry basket under the chair, have a look and feel what paper it is. (Children raise their hands and say)
Second, explore the characteristics of the paper
Teacher: Are these papers all the same? These different documents have their own special secrets. Do you want to know what secrets they have? Ok, please play with the paper in the laundry list in various ways to see who finds the most secrets. (Good) (Guide children to find that the color and brightness of the paper surface are different, and the feeling of touching the paper with their hands is different, for example, some are smooth and some are rough. )
Now, please blow these papers. What's the difference between them? Then tell everyone what you found. (Guide children to discover the thickness and softness of paper)
Teacher: Now please tear up these papers. What's the difference between them? (Guide children to observe which paper is easy to tear and the changes of paper during tearing. )
4. Teacher: Paper has so many skills. Now let's see what happens to these papers when they meet water. Look carefully. After counting to 10, tell everyone what you found and see who observed it most carefully. (Guide children to compare which paper absorbs water quickly, which paper absorbs water slowly and which paper does not absorb water easily. )
5. Teacher's summary: There are so many kinds of paper, so soft and thin paper is called Xuan paper; White and smooth paper like this is called copy paper; This thick and hard paper is called cardboard; This hairy white paper is called lead paper, as well as handmade paper, kraft paper, corrugated paper, sandpaper and so on.

(Good) Children watch videos.
2. Question: Who invented paper? What material is it made of? How is it made?
3. Paper can make all kinds of things. Have you ever seen anything made of paper in your life? (Please raise your hand and say)
Fifth, know how to cherish paper. Teacher: What should we do to save and cherish paper when using it?
Sixth, the end of the activity
Activity reflection:
I felt deeply after this scientific activity.
At first, I put all kinds of paper in a small basket and let the children find out the different characteristics of all kinds of paper through activities such as touching, watching, comparing and playing. For example, some papers are thick and thin; Some papers are smooth and rough; There are also some papers with different colors. Before class, I also let my children collect all kinds of materials, such as coated paper, rice paper, kraft paper, wrinkled paper and so on. Let children know the paper that can be seen everywhere in life and consciously increase their desire to explore things around them. At the same time, in this process, I also invented a video of paper to let children know about the process of papermaking, and put several kinds of paper with different characteristics into water to let children observe the changes of paper in water and talk about their findings in the experiment. In the whole activity, I can always guide my children with questions, give them space to explore independently, and let them transform into their own knowledge and experience through their own active observation, discovery, perception and exploration. But after the whole activity, I also found that children didn't know much about the use of paper, and some materials were not effectively used by children. For example, all links are closely linked, but I control the time of children's independent activities closely in every link. When children talk about the use of paper, because they are not rich in life experience, they say little about the use of paper, and I have not strengthened it, so that children's understanding of the use of paper has not been extended, and they still stay on the original experience. Moreover, my observation ability is still lacking in activities, and I can't guide my children to explore further in time in case of emergencies. For example, when children play with paper freely, when I find that children are trapped by experience, I don't guide them in time. In fact, children should be advised to use specific methods to guide them in the process of pulling, tearing and folding, so that children can compare several kinds of papers and experience them in all directions. Because of my mistake, the child's thinking is limited, so that the child's experience can not be improved.
Through this activity, I realized that when organizing scientific activities, I should also exercise my ability to deal with emergencies and master the whole class, and try my best to teach calmly and leisurely. At the same time, we should fully understand children's age characteristics and experience level, and attach importance to their interest and enthusiasm for inquiry.
