Large class science 1 activity goal magic teaching plan
1, let children find that objects will fall freely when thrown into the air, and the falling speed of different objects is fast or slow.
2. Cultivate children's ability of experiment and observation.
3. Stimulate children's interest in scientific inquiry.
4. Willing to try boldly and share experiences with peers.
5. During the activity, let the children experience the joy of success.
Activities to be prepared
All kinds of paper balls, sandbags, mineral water bottles, medicine bottles, plastic bags, newspapers, pine cones.
Activity process
First, guide children to perceive the phenomenon of free fall of objects.
1, teacher "Today, the teacher has prepared a lot of things to invite you to play throwing games."
2. Game requirements: Choose one item at a time and try to see who finds more problems.
3. Children are free to operate the individual guidance of the teacher.
4. What did you throw just now? How do you feel when you throw these things? What is the final result? What problems have you found?
Second, throw the object again and find that the falling speed of the object is fast or slow.
1, practical requirements: children choose two toys at a time and throw them at the same time to compare the falling speed of objects.
2. Choose an object that you think will land quickly.
3. What do you find is falling fast and what is falling slowly?
Summary: Today we played an interesting game, knowing that objects will fall down after being thrown up. That's because the earth is attractive. Moreover, it is found that light and large objects are not thrown high and fall slowly, while heavy and small objects are thrown high and fall fast.
Fourth, inspire children to explore ways to change the falling speed of objects.
The teacher showed two identical pieces of paper to motivate the children to fall at different speeds.
Verb (abbreviation for verb) extends activities.
Watch videos of people in space.
Try to change the speed at which two pieces of paper fall.
Activity reflection
Attraction is an invisible and intangible force. How to make children understand attraction? I chose the game activity-throwing things. First of all, I felt the falling of objects. Secondly, I compared the falling speed of two kinds of objects and discussed how to change the falling speed of the same object again. Let children actively participate in the game, and strive to guide children to complete their learning tasks through feeling, exploration, discovery and guidance. In this way, children will change from passive learners to active learners and explorers, thus cultivating children's experimental and observation abilities.
How to change the falling speed of the same object in the extended activity experiment? It is intended to organically combine collective scientific activities with regional activities. Through children's positive thinking, children's interest in practical exploration is aroused again, thus sprouting their positive feelings of loving science.
In practice, I feel that I have more observation and thinking in teaching activities, and I can adjust my thinking in time. In the preset activities, I have been considering whether to use the recording table, but considering the children's lack of basic experience, I chose to let the children choose objects that he thought would land faster in practice, but the result was just the opposite of my expectation, newspapers and plastic bags were chosen by the children, so I immediately realized this, and introduced the relativity of speed into teaching activities in time, which not only enriched the children's cognition, but also realized their breakthrough in wearing new shoes and taking the old road in teaching activities. I think there are still a few problems in implementation.
1, the experimental materials are not carefully considered, and some materials can be enriched, such as various candy paper, wrapping paper, feathers, snowflakes, handkerchiefs, paper cups, straws, plasticine, balloons, etc.
2. When children play games, many children will tell me his findings at the first time, but some children are not very active in group communication. For this phenomenon, I think there are reasons for children's personality and our usual exercise guidance. Because one of the disadvantages of group activities is that everyone can't have a chance to speak, I can try to establish a peer exchange link in the future, so that they can communicate with each other and choose representatives to speak in the group, which not only encourages children to communicate but also makes them feel the joy of cooperation.
3. Although I tried my best to be a supporter and guide in the activity, I talked a lot less about children's experiments compared with previous teaching activities, but I was eager to replace them when summing up.
The magic lesson plan of science class 2 activity intention:
Children in large classes should be made to understand the relationship between invisible and intangible forces and the movement of objects. It's hard for children to accept. Only by letting children participate in various operational activities and play purposeful games: trying to feel, explore, discover and complete learning tasks can children turn passive learners into active learners and explorers, thus sprouting positive feelings of loving science.
Activity objectives:
1, due to the gravity of the earth, all kinds of objects will fall freely in the air.
2. Sensing the fall of different objects is related to the gravity of the objects and the buoyancy of the air.
3. Change the falling speed and cultivate children's ability of experiment and observation.
4. Make children interested in exploring natural phenomena.
5. Stimulate children's interest in scientific activities.
Activity preparation:
White paper, small sandbags, feathers, clips, ribbons, building blocks.
Activity flow:
First, feel the phenomenon of free fall of objects.
(1) Throw this sandbag (white paper) on it, what will you find?
(2) What are these things? (falling)
Why do things thrown up fall down?
Due to the gravity of the earth, the thrown object will fall freely in the air.
Second, the falling speed of objects is fast and slow.
(1) Which items fall fast and which ones fall slowly? (same height)
(2) Explain the form, and children will work together to complete the form.
(3) When throwing objects at the same time, the falling speed is fast or slow.
(4) proofreading the form, * * * found that white paper, feathers and ribbons fell slowly, while sandbags, clips and building blocks fell faster. Why?
Summary: I know that all objects will fall because of the gravity of the earth. At the same height, the heavy one will fall faster than the light one. Light and large objects are not thrown high and fall slowly; Heavy and small objects will fall quickly when thrown high.
Third, children try to explore.
1, is there any way to make two identical papers and one drop faster?
2. Imagine boldly and try to find out the answer.
If you hold a piece of paper, it will fall faster.
Knowing that an object changes will also change its speed.
Activity expansion:
Let children continue to perceive in regional activities.
Activity reflection:
Attraction is an invisible and intangible force. Through the layer-by-layer guidance of the game, we first perceive the falling phenomenon of objects, then compare the falling speed of two objects, and discuss again how to change the falling speed of the same object, so that children can actively participate in the game, and try to guide children to complete their learning tasks through feeling, exploring, discovering and guiding. In this way, children will change from passive learners to active learners and explorers, thus cultivating children's experimental and observation abilities. Let scientific activities smoothly extend to children's daily activities, not for teaching, but for children's learning, highlighting children's initiative and autonomy.
Large class science magic lesson plan 3 activity goal:
1. Children recall, associate and perceive various forces and their functions through various operational activities and games.
2. Explore the relationship between the magnitude and direction of force and the movement of objects in the game.
3. Inspire children to love science, observe the movement of surrounding objects and enjoy exploration activities.
4. Actively participate in exploration activities, sprout curiosity and experience success and happiness.
5. Be able to boldly carry out practical activities and express your views in complete language.
Activity preparation:
Materials: rubber ball, shuttlecock, sandbag, rubber band, car, shot put, tambourine, castanet, harmonica, tambourine, baseball, two bags of rice, two buckets of water, trolley and various auxiliary materials.
Experience: Children know what they often do.
Activity flow:
First, stimulate interest, introduce theme activities, and guide children to tell their own life experiences.
1, Teacher: Today we are looking for an invisible friend. His name is Li. Do you know where we need to exert ourselves in our daily life? It turns out that there are powerful beings everywhere around us, and it takes effort to do anything.
Let's make friends with Li today, shall we?
Second, guide children to operate activities and feel that the movement of objects requires strength.
1, Teacher: The teacher has prepared many interesting things for the children today. We gave these toys a nice name-objects. For example, desks and cabinets in the classroom are called objects. How to make these objects move? Now, please come and have a look, talk and play. After playing, tell everyone how you will play. (Teachers participate in game activities)
2. Children speak freely: I clap the ball with my hand, I throw sandbags with my hand, I use a trolley ... I turn the ball with my hand ... (guide children to pay attention to words)
3. Teacher: Hey, why don't these toys move here? (Because toys only move when their hands or feet are hard)
4. The teacher explained while operating: the movement of an object needs force, and the object will only move if it is acted by force.
Third, through children's re-operation of objects, children are guided to discover the relationship between the magnitude of force and the movement of objects.
1, Teacher: Now, children, the teacher will come to play with you, but you have to experience it. What happens with a gentle push? What happens when you push hard? After playing, tell everyone what you found. Teachers participate in children's activities and guide children to express themselves in correct language.
2. Children can speak freely after operation: when we exert great force, objects will be thrown high, rolled far and moved quickly. When we use less force, the object will be thrown very low, roll not far and move very slowly. ...
Four, children's operation, guide children to recall the labor-saving places in life, and cultivate children's imagination and creativity.
1, Teacher: Let's play a game and transport things. I have two bags of rice and two buckets of water here. Please consider how to move them there.
2, children, operating experience, teachers involved in guidance.
Teacher: It's clever of you to think of so many ways to transport rice and water here. Why use these methods?
Teacher: It turns out that these methods are relatively labor-saving. Please think about it, where do we need to save effort in our daily life?
Teacher: What do you think you need to do now? How do you want to save it? What can you invent?
Teacher: I found that all our children are small inventors, but now we need to learn more skills to realize your dream!
Abstract of intransitive verbs
Today we found an invisible friend. His name is "Li". Force can make objects move. "Force" is amazing, really "amazing force".
Activity reflection:
Attraction is an invisible and intangible "power". Through the layer-by-layer guidance of the game, we first perceive the falling phenomenon of objects, then compare the falling speed of two objects, and then discuss how to change the falling speed of the same object, so that children can actively participate in the game and strive to complete the learning task through feeling, exploring, discovering and guiding. In this way, children will change from passive learners to active learners and explorers, thus cultivating children's experimental and observation abilities. Let scientific activities smoothly extend to children's daily activities, not for "teaching", but for children's "learning", highlighting children's initiative and autonomy.
Four objectives of the magic teaching plan for large class science:
1, let children find that objects will fall freely when thrown into the air, and the falling speed of different objects is fast or slow.

5. Expanding activities: Watch videos of people in space and try to change the falling speed of two pieces of paper. Reflection on Magic Teaching Activities: Attraction is an invisible and intangible "power". How do children understand attraction? I chose the game activity-throwing things. Through the layer-by-layer guidance of the game, I first felt the falling phenomenon of the object, then compared the falling speed of two objects, and discussed again how to change the falling speed of the same object, so that children can actively participate in the game and try to complete the learning task through feeling, exploring, discovering and guiding. In this way, children will change from passive learners to active learners. Double-click here to modify or delete the header and footer information, and cultivate children's ability to experiment and observe. Designed activity extension experiment: how to change the falling speed of the same object, with the intention of organically combining formal scientific activities with informal scientific activities (regional activities), and through children's positive thinking, arouse children's interest in practical exploration again, thus sprouting children's positive feelings of loving science. In practice, I feel that I have more observation and thinking in teaching activities, and I can adjust my thinking in time. In the preset activities, I have been considering whether to use the recording table, but considering the child's lack of basic experience, I chose to let the child choose objects that he thought landed faster in practice, but the result was just the opposite of my expectation, except newspapers and plastic bags, which were all chosen by the child himself, so I immediately realized this, and introduced the relativity of speed into teaching activities in time, which not only enriched the child's cognition, but also realized that he wore new shoes and walked the old road in teaching activities. I think there are still several problems in the implementation:
1, the experimental materials are not carefully considered, and some materials can be enriched, such as various candy paper, wrapping paper, feathers, snowflakes, handkerchiefs, paper cups, straws, plasticine and balloons.
2. Many children will tell me his findings at the first time when playing games, but some children are not very active in group communication.

3. Although I tried my best to be a supporter and guide in the activity, I talked a lot less than previous teaching activities, and more about children's experiments and children's summaries, but I was eager to replace them when summing up. Looking back on my previous teaching activities, there are some new attempts almost every year. Although I always ask myself "why can't I be as calm and confident as a teacher in Shanghai", I can find some problems in the implementation, which also makes my teaching thinking clearer and the teaching purpose clearer. I think observing teaching activities is a guide to the growth of our front-line teachers, which can make us mature constantly, so we should cherish every opportunity to grow up!
Self-examination/introspection
First, I think this new form of listening activities has changed the traditional listening mode in the past, and teachers can attend classes with expectation and positive thoughts.
The selection of materials for the second and seventh teaching demonstration activities is based on life, which embodies the characteristics of different ages and has good operability and practicality, and is a good material for each of us to practice again.
Thirdly, the exquisiteness of teaching activity design is worth learning. I remember that at the beginning, our observation activities were like a platter, and everything was called comprehensive activities. Now you can clearly see the teacher's teaching focus, and you can also deeply appreciate the benefits of subject integration: the integration of Xiao's life and language, Yao's art and health, Wang's science and language, double-click here to modify or delete the header and footer informatics, Liu's science and language, Xue Lian's art and mathematics and language, and Teacher Li's science and language.
Fourth, the preparation of teaching activities is simple and effective. In our previous observation activities, there have been many formal materials and fancy. The material transfer of this activity is worth learning from all of us. The more novel the material, the better. It is very important to be effective and operable.

7. Activity extension: let children continue to perceive in regional activities.
Commentator of "Magic" activity: Wu Rong's activity evaluation: Teachers can pay attention to children's hobbies and formulate the theme of the activity according to the content of children's life experience. In the activity, the teacher set up three operation activities according to the principle of step by step, so that children can feel the falling of objects related to the gravity of the earth, the weight of objects and the buoyancy of the air from the initial play to exploration and discovery. By trying to change the speed of falling body, children's creativity can be brought into play and their hands-on ability can be cultivated.
Activity suggestion:
1. The arbitrariness of teacher education needs to be further deepened.
2. Teachers' demonstration operation needs to respect the objective reality.

Science and Magic Teaching Plan 7 Activity Target in Big Class
1, in the hands-on operation, stimulate children's interest in exploring friction.
2. To develop children's thinking, you can try to change friction in various ways.
3. Guide children to understand friction and feel the influence of different materials on friction.
Activities to be prepared
1, courseware: picture-gyro
2. Glass balls, dried dates, inclined planes, tires, hemp ropes, clothes with zippers, candles, beverage bottles and towels.
Activity process
First, import
1. Perceive the existence of friction and stimulate children's interest in learning.
Ask some children to demonstrate tug of war.
2. Let the children tell how they feel after holding the rope.
Teacher: We will feel a force to stop our hands from rubbing against the rope. This is called friction.
Second, expand
1, Teacher: Friction is a magical force, which is ubiquitous in our life.
And it has a strange temper, that is, sometimes it is big and sometimes it is small.
Do you want to study this strange friction with your teacher?
2. Experiment: Friction
Understand the friction force through experiments and feel the influence of different materials on the friction force.
You should know that the magnitude of friction is related to the roughness of the contact surface.
(1) Let the gyro turn on a smooth board and a board covered with velvet, and compare which gyro will stop first.
Q: Which gyro will stop first and why?
The gyro on the board covered with flannel will stop first, because the flannel is rough and has high friction;
Smooth wooden board has smooth surface and low friction, so the gyro rotates for a long time.
(2) Competition between glass balls and dates.
Guide children to experiment in groups: put the glass ball and jujube in the bottle on the plate,
Let's see which group finishes first.
Question: What did you find this time? What does friction have to do with it?
The magnitude of friction is related to the roughness of the contact surface. The contact surface between objects is smooth and the friction is small.
The contact surface between objects is rough and the friction is large.
3. Find ways to reduce and increase friction.
Sometimes the friction is big, sometimes it is small, sometimes it will help us, sometimes it will bring us trouble.
Now please use your head and let friction help us do good things.
(1) What should I do if the zipper on my clothes doesn't open?
Let children try to use candles to reduce friction to solve the problem. )
(2) What should I do if the bottle cap can't be opened?
Let the children try to wrap the bottle cap with a towel to increase friction to solve the problem. )
4. Understand the application of friction in life.
Enlarge: the patterns of shoes and tires, runways, spikes, etc.
Reduce: lubricating oil, maglev train, etc.
It turns out that friction can be increased or decreased. We children should use our brains and let them help us.
Third, the end.
Children can freely discuss what frictions are left in their lives.
