Teaching plan for children's scientific observation activities
Activity goal 1, understand how the thread is spun.
2. Understand the difference between ancient and modern spinning wheels and experience the great wisdom of working people.
3. Cultivate children's observation ability and hands-on ability.
Activities to be prepared
There are several threads of different materials and colors, videos about spinning, ancient spinning wheels, cotton and dyes of different colors.
Emphasis and difficulty: Understand how the thread is spun.
Activity process
First, explore different routes and introduce activities.
Show different lines and let children observe and explore freely.
Teacher: "What lines do you like best, little friend?" (Children speak freely)
Teacher: Do you know how these lines come from? Let's go and have a look! "
Second, show the video: the process of modern machine spinning.
Watch with the children and listen to the teacher's introduction while watching, so that the children can understand the advanced spinning technology now.
Teacher: bounce cotton, remove impurities, make it fluffy and soft, rub it with your thumb into a spinning strip with a thickness of more than one foot, then spin it into thread with a spinning wheel, then go through many processes such as warp, sizing and drying, and finally put it on the loom.
Third, let the children see the ancient spinning wheel.
Teacher: Just now, we watched the working process of modern machine spinning together. Now look here.
The teacher showed the spinning wheel and made a detailed introduction for the children to understand.
The teacher introduced the spinning wheel while operating, so that the children could learn more about the ancient spinning process.
Encourage young children to try this spinning method.
I am a little spinner.
Show the cotton and let the children discuss with each other how to turn cotton into thread.
The children operate the experiment in their own way, and the teacher makes a summary to encourage them to find another way. The child operated the experiment many times.
After many hands-on experiments by teachers and children, cotton was finally twisted into a thread. )
Five, multicolored lines.
Children can freely choose their favorite dyes, rub their own threads and dye beautiful colors.
6. Let the children take the colored thread outdoors to dry.
Activity expansion
Encourage children to paste interesting graphics with colored lines.
Chapter II Teaching Plans for Children's Scientific Observation Activities
Activity goal: 1. Perceive the speed of free fall and be interested in exploring scientific mysteries.
2. Find out the phenomenon of free falling of different objects.
3. Learn to record the falling speed of two different objects with statistical tables.
Activity preparation:
1. Two items with obvious light and heavy contrast (one for each person). Such as sandbags and foam boards, feathers and plasticine, plastic bags and iron plates, cloth pieces and plastic toys.
2. Two pieces of paper of the same size.
3. Several items with the same quality and shape but different sizes. For example, triangle iron, milk bottle, beverage bottle and potato chip box of the same size.
4. There are three big statistical tables, which respectively represent the decline of three kinds of articles. Each person has a sub-statistical table.
Activity flow:
(1) Explore the falling phenomenon of two objects with different weights.
1. Show sandbags and foam
Let the children guess: "What will happen if these two things fall?"
2. Experimental sandbags and foam falling.
Question: "What did you find when these two items fell? Why? " (light is fast, heavy is slow)
Children are free to explore two different projects.
Requirements:
(1) Two projects are placed at the same height.
(2) Exchange two kinds of goods with friends.
4. Summarize the conclusion and make statistics (summary, heavy items end quickly, light items end slowly)
Teachers come up with big data to help children understand how to record.
5. Children make their own statistical conclusions, summarize the statistical situation and show statistical tables.
(2) Explore the falling phenomenon of items with the same mass but different shapes.
1. Take out two pieces of paper of the same quality and size and knead one of them into a ball.
Let the children guess: who will fall fast?
2. Try it, son.
3. To sum up, small shapes fall quickly. And record it on the big statistical table.
(3) Explore the falling phenomenon of items with the same quality and shape but different sizes.
1. Show me triangles of different sizes.
(1) Let the children talk about their similarities (quality, shape) and differences (size).
(2) Guess: Who landed first? Or is there something else?
2. Experiment. The conclusion is: landing at the same time.
3. Verify and display bottles and potato chip boxes of different sizes.
4. Record the conclusion on the big statistical table.
Article 3 Teaching plan for children's scientific observation activities
Activity target 1. Explore the different characteristics of several kinds of paper in operation, and find that several kinds of paper have different water absorption.
2. Be able to speak out your findings boldly and develop your oral expression ability.
3. Boldly participate in scientific activities and cultivate the ability of exploration and discovery.
Activities to be prepared
1, each person has a small basin, and there are several napkins, newspapers and calendars in the basin.
2. There is a small square plate on each table, in which there is red paint water, and several small sticks are prepared. There are three kinds of paper on the stick, and the length of the paper is the same.
Stick three kinds of paper on the blackboard with five-pointed stars on it.
Activity process
First, understand three kinds of paper and explore their different characteristics.
1. What's in the small basin in front of you? What kind of paper do you have?
2. Let the children touch them with their hands and find out the differences between these papers.
3, teachers and students * * * Summary: napkins are hairy, newspapers are smooth, and calendar paper is the smoothest.
Second, understand the water absorption characteristics of paper
1. (Showing a plate of red water) Here is a plate of red water. Today these papers are going to play a game with red water. Please hold the paper in your hand like a teacher and immerse it in the water. Take a closer look. What will happen to the water? What happened to the newspaper? I'll tell you later.
2. Pay attention to children's issues
What did you find just now?
How did the water get on the paper?
Guide children to conclude that paper has the ability to absorb water.
Third, explore the different water absorbability of three kinds of paper.
1, napkins, newspapers, calendars and paper have the same water absorption capacity? Let's hold a water absorption competition.
2. Guide children to explore the competition method: put three pieces of paper on the stick into the red water at the same time and observe which paper absorbs the red water quickly.
3, children's operation, guide children to carefully observe the changing state of paper color rise.
4. Organize children's communication.
Who has the ability to absorb water, who is the first? Who is the second place? Who was the last one?
5. Teacher-student summary: napkins absorb water the fastest, newspapers absorb water slowly, and calendars absorb water the slowest. Three kinds of paper are marked with 3 stars, 2 stars and 1 star on the blackboard, indicating the first, second and third respectively.
Fourth, experience transfer.
A child cried and shed a lot of tears. With these three pieces of paper around him, which paper should he use to wipe his tears? Why?
