The activity design concept of scientific activity teaching plan 1;
Children all think that rainbows are magical. Rainbow can only be seen after rain, but not on sunny days. Children will be curious and ask, "The rainbow is so beautiful that you can only see it after the rain, but you can't see it on a sunny day. Why should the rainbow hide? " Aiming at the bold question of children, I designed this topic, so that children can understand why rainbows can only be seen after rain in the process of trying.
Activity objectives:
First, let the children understand the basic characteristics of the rainbow, and initially understand the causes of the rainbow.
Second, stimulate children's interest in natural science through experiments.
Third, learn and exchange experimental results with peers.
Technical support for activities:
Pictures of water, pots, mirrors, sprayers, cups and rainbows.
Activity process and method:
First, through the riddle, lead to the topic.
Riddle: "The sky of the Long Bridge is colorful and really beautiful. You can't find it on a sunny day, but it will appear after the rain." (Answer: Rainbow)
Second, show pictures to help children remember the characteristics of the rainbow.
Have you ever seen a rainbow? Where will the rainbow appear?
(2) What shape is the rainbow? What color is the rainbow?
Third, experiment: make your own rainbow.
(1) The children discuss in groups what they need to make a rainbow.
(2) Let children choose spray gas, mirror, water, pot, transparent cup, white paper, etc. Try to make a rainbow, and the teacher will guide them.
Teacher's guidance: 1 The teacher sprayed the air with spray gas, and the child observed the phenomenon with his back to the sun. 2. Facing the sun with a transparent cup filled with water will also produce a rainbow phenomenon.
3. Insert half of the small mirror into the water obliquely, and put a piece of white paper on the opposite side of the mirror, so that sunlight can be reflected on the white paper, and a rainbow can appear on the white paper.
Fourth, exchange and discuss:
(1) Q: Did your rainbow appear?
(2) Q: What tools do you use to make rainbows? Summary: Rainbow is an arc ribbon formed by valuable colors, just like a bridge in the sky. Rainbow has seven colors: red, orange, yellow, green, cyan, blue and purple. The colors in spray, white paper and cups are all the colors of the sun. The seven colors that appear after the sun refracts water drops, mirrors and cups are the sunlight when they are mixed together. After a thunderstorm or shower in summer, there will be small water droplets in the sky. When the sun shines on these small water droplets, beautiful seven-color rainbows will appear in the sky. The sky is clear, and there is no rainbow without rain.
The expansion of verb (verb's abbreviation);
1. Please think about whether there are other ways to make a rainbow.
2. Ask parents and children to look for information about rainbows together.
Innovation of activities:
First, try to provide children with opportunities to try, so that children can learn to borrow tools and avoid the limitations in the operation process.
Second, give children the opportunity to communicate, let children find problems from communication, observation, operation and small experiments, and ask questions boldly.
Activity result forecast:
Children can learn in play, freely discuss and express their opinions, and freely choose tools to make rainbows, which is in line with the characteristics of children's love of hands, brains and exploration, and the effect is good.
Scientific activity teaching plan Part II Activity objectives:
1. Conduct activities in groups, and experience the fun of playing games through planned division of labor and cooperation.
2. Explore and try to use different methods to build heights and develop children's spatial imagination and ability to use measuring tools.
Activity preparation:
40 boxes of milk (4 servings); Tape measure; Marker (one red and one black); Recording paper; blackboard
Activity flow:
First, define the task and form a group.
Explain the task, play group games in groups of four, and name the group.
The teacher designed the table on the blackboard and asked each group to draw their own marks on the table. Such as (strawberry team, watermelon team, etc. )
Put forward the requirements of the game: the cooperation base of four people is high and the base is stable. All milk cartons should be built, and the game will be over as soon as the bell rings.
Second, the initial cooperation base is high.
Children have a high base and teachers patrol.
Third, summarize the first foundation height.
Did it work? Why is it successful? What marks are used to indicate success; What can failure express?
Please send a representative from each group to record in the form.
Discuss why the cardinality is high and low. (Different ways, different heights)
Fourth, the base number is higher.
Put forward new requirements, high and steady.
Discussion on verbs (abbreviation of verb)
1, which group is the highest? how do you know
Step 2 measure. The teacher demonstrated the measurement method and the children recorded it in the form.
3. Why do many milk cartons have different heights?
Sixth, the third base is high, and the champion and runner-up are decided.
Children measure their basic height scores and record them in the table to decide the champion and runner-up.
Discuss what signs to use, such as five-pointed star, triangle, etc.
Seven. Collective discussion
How can we stand on high stability?
Height: The more layers erected, the higher.
Steady: the bottom should be built steadily, and the two can be placed horizontally together.
It also needs the joint efforts of the team members.
Scientific Activity Teaching Plan Part III Activity Design Background
Children in large classes already have certain thinking ability, so they always ask some questions. The design of this teaching activity aims to help children better understand some laws and changes in nature. At the same time, in the face of the situation that individual children in the class are unwilling to communicate with other children, this activity is also to try to pull them into a large group and create opportunities for them to communicate.
moving target
1. Let the children realize that the little ants moved to avoid the rain flooding their homes.
2. Let children know through activities that the behavior of small ants moving is a sign before it rains in nature.
3. Let the children list other natural signs before it rains.
4. Let children experience the happiness of group activities.
5. Stimulate children's interest in scientific activities.
Teaching emphases and difficulties
Key point: let children understand that the behavior of small ants is a sign before it rains in nature.
Difficulty: Let children list other signs before rain in nature through the movement of small ants. After all, children's abilities are limited.
Activities to be prepared
Large transparent glass box without cover, ants, sand, large water cup and water.
Activity process
1. Start the link
(1) The teacher asked, "Little friend, do you know why we can always see small ants moving high on weekdays?" Then, wait for the child to answer.
(2) Organize children to approach the lecture table and prepare for the demonstration.
2. Basic links
(1) Put a pile of sand at one end of the glass box, and then put the ants at the end where there is no sand.
(2) Wait a minute. The teacher asked, "Children, which one of you can talk about the activities of small ants now?" Pay attention to guide the children and let them say that the little ants are running around in the box.
(3) Start adding water to the sand-free end of the glass box for children to observe.
(4) The teacher asked, "Who can talk about the activities of small ants now?" Obviously, the children's answer will be that the little ants run to the sand.
(5) Teachers begin to extend. The teacher asked, "In nature, under what circumstances will the low-lying areas of the earth be flooded?"
(6) Guide children to say it's raining.
(7) The teacher asked, "If the glass box without sand is like a depression, what will happen if we add water to the glass shoes?"
(8) Guide children to say that it is raining.
(9) Guide again. The teacher asked, "So, children, now please tell me why this little ant moves?"
(10) children answer
(1 1) To sum up, small ants move to avoid the rain flooding their homes, and their move is a sign before it rains in nature.
Step 3 end the link
(1) Assume that the podium is a sand pile and other places are flat.
(2) The teacher shouted, "It's sunny. What about those little ants? "
(3) It means that children are laughing and running around in the classroom.
(4) The teacher shouted, "It's going to rain soon. What should the little ants do? "
(5) said the child ran to the podium.
(6) End with laughter
Step 4 extend the link
Before class, the teacher asked the children, "Children, please use your brains after class and carefully observe the behavior of other small animals around us." Is it a sign before it rains? " Let's share our observations next class. "
Teaching reflection
1. Children in large classes already have certain thinking ability, but their thinking ability is limited after all, so the guidance of kindergarten teachers is particularly important. It is very important for kindergarten teachers to master the involvement of the whole activity and give full play to the main role of children.
2. Reflection on the activity process:
(1) Reflection on children's development. When children are happy to see the activities of small ants, most children can take the initiative to participate in the activities. This activity can make children think about daily life phenomena and exercise their brain development. In the final game activity, children who are unwilling to communicate with other children also participate in the activity, which helps to improve their withdrawn personality.
⑵ Reflection on teachers' professional development. This activity is carried out on the basis of mastering children's experience level, learning characteristics and personality, which can grasp the core value and development clues of educational content and promote children's maximum development. However, I personally think that weak countries are still more interesting in the whole observation activity.
⑶ Reflection on the interaction between teachers and children. It is naturally a little difficult to guide children from classroom experiments to outdoor, but it is much better in later games. Personally, I think other activities can be interspersed in the experiment to help children understand.
3. Evaluation of the effect of the activity. At the beginning of observation, the child showed great interest, but in the final guidance, it seemed a little lack of interest. Fortunately, the last game aroused the children's interest. In the guidance session in the future, multimedia and fun activities can be properly used to help children understand.
If I take this course again, I will use experiments and multimedia to help children understand, and I will pay attention to more details to keep the activities coherent and interesting. But personally, I think the last game should be kept. After all, children like games. In the whole activity, I will let the children find more problems themselves, highlight their dominant position, and let the children entertain and educate.
Scientific activity teaching plan 4 activity objectives:
1. Through the comparative perception of various senses, we know that water is colorless, odorless and transparent, and water can dissolve some substances (sugar, salt, etc. ).

2) Ask individual children to try it.
3) Q: Why is this glass of water sweet?
2. Children's hands-on activities.
1), guide children to observe the color and taste of sugar and water, which are white and colorless, sweet and tasteless respectively.
2) Put the sugar into the water and gently stir. Slowly, the sugar disappeared. Where's the sugar?
3) Take a sip of water through a straw and see how it tastes?
4) Do another experiment with salt.
5) Summary: Water can dissolve sugar and salt.
(4) Merger activities
1. Discuss what else can be dissolved in water?
2. Let the children put the stones, colored plastics, washing powder and other things provided by the teacher in the water, and after a while or stir them to see what is missing. Where have they all gone?
Remind children to go home and continue to do similar experiments.
What is the use of water? How should children save water?
Teacher's summary: Water is an important part of organism and an indispensable substance in life. In addition, children have great special feelings for water, especially when the weather is hot, bathing has become a great pleasure for children.
