The Yangtze River Basin 1 the activity target of teaching plan in science big class;
1. Know the names and characteristics of common insects.
2. Feel the mystery of the insect world.
3. Cultivate the ability to observe and compare insects.
4. Actively participate in activities and experience the joy of activities and the joy of success.
5. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
Activity preparation:
1, catch insects with various tools and visit the insect museum.
2, multimedia production-insect doctor, insect detective pictures or insect videos.
Highlights and difficulties of the activity:
Learn to distinguish insects from non-insects according to key characteristics.
It is found that insects have the same appearance characteristics, and the concept of insects is initially formed.
Activity flow:
First, evoke memories.
Visit the Insect Museum and introduce the names of insects.
Second, learn to be an insect doctor.
1, Challenge 1: Look at the shadow and guess who I am?
2. Challenge 2: Hide and guess who I am? (showing obvious local insect characteristics)
Communication: longicorn's tentacles indicate age, and mantis's front legs are like barbed knives. Harms and benefits of ladybugs, such as: ladybugs are beneficial insects and ladybugs are pests.
3. Challenge 3: Who has the best vision?
Look at the picture quickly, close the picture and remember which insects there are.
What insects are hiding in it?
Open the picture again and see what insects are there.
4. Challenge 4: Guess what insects will be with them?
Show flowers, thunder marks and light bulbs, guess bees, butterflies, fireflies and other insects.
Third, establish an insect museum.
1. Insects are a big family. Although the names are different, family members have a lot in common. Find out what they have in common
2. From the above insects, we found the common features of Insectidae and posted them on the exhibition board one by one.
There are many insects in the insect museum today. Some are not insects, please find them.
The teacher released spiders, frogs, longicorn beetles, bees, snakes, crabs, unicorns and snails. Become the original insects and ask the children to find out the insects that are not insects. )
4.* * * Check right and wrong, give reasons and bid farewell to friends who are not insects: "Sorry, you can't live in an insect house."
(For example, a spider with eight legs and a snail without legs are not insects, while bees conform to the characteristics of insects and are insects. )
5. The Insect Museum is open. Play the video and feel the mystery of the insect world.
Activity reflection:
Insects are things that children are interested in, and children have a deep desire to explore in life. During the activities, children's cognitive ability and language expression ability were greatly improved. Children's participation is also relatively high, and they can actively express their understanding of insects. Moreover, in the activity, the communication between teachers and children is mainly children, which is in line with the children's discovery and understanding. Make the activity more vivid.
Disadvantages:
There is a little less encouraging language in the activity.
Design background of activity 2 of large class science teaching plan in the Yangtze River basin
With the destruction of the environment around us, the air on which we live has been seriously polluted. Facing this severe problem, it is urgent to protect the environment and purify the air. In order to have a clean and fresh environment for future generations, we should start with children and let them know the importance of good air from an early age. So I designed this activity, hoping that adults can set an example for their children.
moving target
1. Perception of air characteristics through activities.
2. Cultivate hands-on operation ability and interest in learning.
Try to feel the characteristics of air and its existence by yourself.
4. Be able to use various senses to learn simple ways to explore the air.
5. Cultivate children's awareness of caring for and protecting the environment.
Teaching emphases and difficulties
Teaching emphasis: being able to perceive colorless, odorless and shapeless air.
Teaching difficulty: the characteristics of children's hands-on operation to perceive air
Activities to be prepared
Plastic bag, balloon, candle, lighter, transparent glass, washbasin and water.
Activity process
First, the initial link:
Riddle introduction: There are things around us that can't be seen, touched, smelled or colored. However, no one can do without it. (air)
Second, the basic link
1. Sensing the characteristics of air:
(1) Please touch the air; Smell it; Catch it. Can you see it? Can you smell it?
(2) The teacher demonstrated how to catch air with plastic bags. Children's hands-on game: catching air.
(3) Summary: The air is colorless, odorless and invisible. It's everywhere, everywhere.
2. Perceive the existence of air:
(1) Pick up a balloon and blow it up. Q: Why did the balloon get bigger? Then gently release the child and ask the child: Do you feel it?
(2) Children play games together and feel the existence of air.
(3) Let two children hold the blown balloon mouth, then put it into the basin and let it go gently. What did you find? Why is there a bubble? Other children take turns to operate.
Three. Closing meeting:
1. A preliminary understanding of the role of air:
Light the candle, let the child fasten it with glass, and then watch the candle go out for a while. What's going on here? There is no air. Without air, people, animals and plants can't live.
2. Summary: (Extended)
In life, where else can we use air? (Children's Discussion) Air is very important to us. It can keep us alive, so we should also protect it, otherwise our lives will not survive.
Teaching reflection
The content of this activity is actually very abstract, and how to make children understand it is a difficult point. According to the age characteristics of children, I designed an activity flow with children's hands-on operation as the core. Let children feel the characteristics and functions of air in a relaxed and pleasant atmosphere when playing middle school. Using children's curiosity to stimulate their interest in learning has achieved the expected goal, and the effect is very good, even exceeding the expected effect. The children not only experienced the happiness when the experiment was successful, but also enhanced their self-confidence. At the same time, it also cultivates children's observation and hands-on operation ability.
Design background of activity 3 of large class science teaching plan in the Yangtze River basin
According to the emphasis in the new Outline, education should be "closely integrated with children's lives". Therefore, children's science education in our garden not only chooses children's lives as the educational content, but also educates them through their lives. Rotation is a common phenomenon in daily life. When playing with building blocks at ordinary times, I don't intend to let the building blocks rotate, but I will also rotate when sitting in a swivel chair. Rotation also brings a lot of convenience to people's lives. According to children's interests, I organized this course, so that children can rotate their bodies while trying to rotate operating materials such as building blocks and swivel chairs, find many interesting phenomena of rotation and accumulate experience about rotation.
moving target
1, let children discover many interesting phenomena of rotation and understand that rotation is a way of exercise.
2. Accumulate experience about rotation and feel the convenience brought by modern technology.
3. Experience the fun and sense of success brought by operational exploration.
4. Stimulate children's interest in scientific activities.
5. Willing to try boldly and share experiences with peers.
Teaching emphases and difficulties
Let children participate in the experiment, so as to cultivate children's interest in science, stimulate children's desire to explore, and cultivate children's ability to find and solve problems with scientific attitudes and methods.
Activities to be prepared
Windmills, gyroscopes, building blocks, small bowls, umbrellas, round pieces of paper, wheels, chopsticks and other items.
Activity process
First, the beginning link: the introduction of heart-to-heart talks to stimulate children's interest in exploration.
Teacher: Do the children know what can be rotated in our life?
Young: (most children are invited to speak)
Teacher: Why does it rotate?
The children answered and the teacher summarized. (Transition to the next link)
Second, the basic link: children explore the operation and encourage them to discover various interesting phenomena of rotation.
After summing up the reasons why things rotate, the teacher provided the children with chopsticks, wheels, small bowls, umbrellas, circular pieces of paper, gyroscopes, building blocks and so on. Introduce the materials and explain the requirements of the activity.
Teacher: The teacher brought a lot of things today. Let's see what we have.
Young: (Let the young children say their names)
Teacher: Can you find a way to make these toys spin?
Young: (children's group communication)
Teacher: Please watch while playing and see what interesting phenomena you find.
Let children explore in activities, gain various experiences, accumulate various perceptual experiences, and actively establish their own understanding. Communicate in groups and make a summary.
Third, the end of the link: through the game, let the children find that rotation is a way of exercise.
Son, can you turn your body without anything? You can try it and see which parts of your body can also rotate. Pay attention to safety when playing, and don't hurt yourself or your children. (free communication)
Fourth, the extension link: the game "find it" and feel the convenience brought by rotation to life.
Let the children talk about the convenience brought by rotation, communicate with the whole class, and then summarize.
Teaching reflection
The new "Outline" emphasizes: "Science education should be closely integrated with children's real life and make use of things and phenomena around them as the objects of scientific inquiry." Therefore, I take children's science teaching as the breakthrough point, and strive to live out children's science education. In the activity design and organization, I also followed the principles in the outline. In this activity, I introduced dialogue, mobilized the children's existing experience and stimulated their interest in the activity. By providing all kinds of familiar operating materials, children can operate, observe, guess and experience in their minds, thus gaining knowledge and experience about rotation. In communication, I adopted the forms of free communication, group communication and collective communication, and let the children explore and discover. However, in communication, I am too single-minded about my children. I just asked the child how to rotate the object, ignoring the interesting phenomenon when the object rotates, and did not make a very careful observation.
Activity objectives of large class science teaching plan 4 in the Yangtze River basin
1, know the trees in autumn, and know that several common trees are changing synchronously with the seasons.
2. Learn to record the different characteristics of the trees you find with simple charts and feel the diversity of the trees.
3. Be able to boldly carry out practical activities and express your views in complete language.
4. Willing to try boldly and share experiences with peers.
5. Make children interested in exploring natural phenomena.
Activities to be prepared
1, wall chart18; Children's books.
Before the activity, the teacher guided the children to observe the changes of the surrounding trees after the arrival of autumn.
3. Find a field with all kinds of trees in advance.
Activity process
1, show the wall chart, and children observe osmanthus trees, orchid trees and buttonwood trees.
Question: Do you know these trees? Can you name them? What trees are these? What are their leaves like?
It's fall here. What changes have you found in these trees?
Do you know any special secrets of these trees? Guide the children to say that trees have leaves before flowering and flowers before they grow leaves. )
2. Children watch children's books-How beautiful autumn is 18- 19 pages of pictures of "all kinds of trees".
Question: Do you know these trees? Can you name them? How did you know?
What do these trees have in common? What is the difference?
3. Children enter the forest (kindergarten playground) and consolidate their understanding of the names and characteristics of various trees in the process of searching for knowledge trees.
(The teacher shows several kinds of leaves) Question: From which tree did these leaves fall? Can you send these leaves back to Mother Tree? Find it and stand next to the mother of this tree.
(2) The reason for the child's judgment: How do you know that this leaf is the mother's treasure of this tree?
③ Observe the mother tree: What does this mother tree look like?
④ The game of "Touch XX and Run Back" consolidated the understanding of various trees.
The children gathered around the teacher. The teacher said the name of a tree, such as "Run back by touching the osmanthus tree". Let the children run, find the osmanthus tree and run back to see which child is faster.
Collect your favorite leaves and bring them back to the classroom and tell me why you like them.
The teacher collects the children's questions about trees and guides the children to draw the questions about trees in the form of pictures and stick them on the theme wall.
5. Painting: a tree in my eyes.
① Children's painting.
② Share communication and feel the diversity of trees.
Activity reflection
In this activity, I went outdoors with my children to observe all kinds of trees. We started from the classroom and walked all the way to see them. With the smell of spring, children show great interest in this personal activity. In the park, we saw weeping willows, arhat pines, cypresses and plum trees ... In the children's works, they vividly showed all kinds of trees they saw and imagined. Wang Yinuo is an introverted little girl. She painted Liu Shu as a beautiful girl, with long braids, swinging with the wind, because in her eyes, Liu Shu is a living person and her good friend. My favorite peach tree is full of colorful flowers, including red, yellow and purple … because peach blossom is the most beautiful in her heart and her favorite.
The Design Background of Science Teaching Plan 5 for Large Classes in the Yangtze River Basin
In physical education class, the children in my class inadvertently put the ball into a bucket full of water for cleaning. I saw the ball was dirty, so I pressed it, washed it, and then let go. The ball floated at once and the children were very curious.
moving target
1. Let children know that objects are ups and downs when put into water through experiments.
2. Cultivate children's interest in natural phenomena and practical ability.
3. Cultivate children's meticulous observation ability.
4. Cultivate children's curiosity about things and be willing to explore and experiment boldly.
5. Stimulate children's interest in scientific activities.
Important and difficult
1, the focus of this lesson is to let children know that water has the force (buoyancy) to hold objects up.
The difficulty is that floating objects will sink in some cases.
Activities to be prepared
Furniture that can hold water (such as pots and barrels) and small balls, stones and dry wood blocks that can hold water.
Activity process
1, let children feel the buoyancy of water in turn. The teacher first asked the children to put the ball in a basin full of water, and the ball floated on the water. Then he asked them to press the ball to the bottom of the water with their hands, so that the children could feel that the water had the power to hold the ball up, and then let go of their hands, and the ball immediately floated on the water. Ask the children: Why does the ball float automatically when we let it go? How do our hands feel when we press the ball? Children say: the feeling of hands being bounced off. Conclusion: This is buoyancy in water.
2. Let the children put the stones and dry wood blocks into the water separately and observe the ups and downs: the stones quickly sink to the bottom of the water, while the dry wood blocks float on the water. Ask the children: why did the stone sink to the bottom of the water, but the dry block floated to the surface? Conclusion: Stone is heavy and easy to sink. Dry wood blocks are light and float easily on the water.
Let the children talk about what we have learned through this activity.
Teaching reflection
1, this class is a science common sense class in kindergarten. It is mainly learned through practice, so that children can find answers in practice, let children feel the fun of the subject better through play, let children find problems themselves, and let children be willing to observe and try. When problems are found, they will solve them.
2. Every child can actively participate in activities and find problems from all angles.
3. Prepare more equipment to do activities in the future, so that every child has the opportunity to do it and make them interested in learning.
If I take this course again, I will change the experimental items, let them try more and let the children know more about ups and downs.
