Teaching plan for scientific activities in kindergarten large classes

Article 1: How did the cotton lines come from?

Design intent

This semester, our kindergarten has set up its own kindergarten-based curriculum. Since most of the children's parents are staff members of the Weiqiao Entrepreneurship Group, in order to let the children know about their parents' work and the contents that are closely related to us around our lives, we designed the contents of the kindergarten-based course according to the actual situation and the age characteristics of the children, such as where the thread came from, various colors of cloth, fast shuttle and so on. But children don't understand the production process of some of these items.

In this activity, we chose "How to make every line come". In learning, children learn knowledge and master skills step by step through observation, exploration, watching videos and hands-on operation, and get happiness from learning.

moving target

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

1. Explore different series and import 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! "

2. Show 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.

Ask the children to watch 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.

4. 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. )

5, multicolored patterns.

Children can freely choose their favorite dyes, rub their own threads and dye beautiful colors.

6. Let the children take colorful threads outdoors to dry.

Activity expansion

Encourage children to paste interesting graphics with colored lines.

Chapter Two: Interesting Shadow

I. Purpose of the activity:

1, to guide children to get the perceptual experience about "light and shadow".

2. Understand the role of shadow and arouse interest in this natural phenomenon.

3, guide children to actively participate in operational activities, stimulate children's interest in exploration and curiosity.

Second, the activity materials:

1, images of various objects cut by colored paper, three-dimensional toys, shadow chessboards.

2, some white paper, flashlight, glue, a piece of recording paper.

3. Some pictures of shadowless lamp.

Third, the activity process:

1 Arouse children's desire to explore by telling "the shadow I know".

Teacher: Do you know what shadows are like?

Teacher: Today, we have prepared four groups of materials to play with shadows. These four groups of materials are all different. You can choose your favorite materials to play with, draw a picture and see what you find.

Children understand the relationship between shadow and light by playing with shadow.

Teacher: What did you find? (A single child demonstrates and introduces the recording results)

Teacher: (sorting out records) When the position of light changes, the shadow will also change; When the position of the object changes, the shadow will also change.

(Figure 1) When the light level is high, the shadow is short. This is because objects block less light.

(Figure 2) When the light is dark, the shadow is long. This is because objects block more light.

3. Play the "shadow chessboard" with the perceptual experience of light and shadow.

Play: Children in pairs, choose red squares and blue squares respectively. Take turns to shine the shadow of the watercolor pen in the middle on the opponent's chessboard. The farthest stop of the shadow in different constellations can get different stars and compare who has the most stars.

4. Various applications of shadows in daily life.

Teacher: Shadows are everywhere in our lives. What role does it play in people's lives? When do we not need shadows?

5, extended activities: stepping on the shadow.

6. Parent-child activities: making shadow clocks

Fourth, matters needing attention

For the effect of activities, it is best to cover the windows of the activity classroom with anti-ultraviolet curtains.

Verb (abbreviation of verb) knowledge background material:

Shadow condition: the object blocks light and has a shadow.

When the light is dark, the shadow is long. This is because objects block more light.

The light level is high and the shadow is short. This is because objects block less light.

Chapter 3: Interesting crabs

Project generation:

In the theme activity of "Earth, Our Common Home", we mainly introduce the animals of the seventh planet from the small class. So the children and teachers collected several kinds of animals, such as rabbits, goldfish and hermit crabs. The children were very interested in these living animals.

In the season of "chrysanthemum fragrant crab fat", the children ate crabs, and they brought crab shells. They said: the cooked crabs are red. Parents don't let their children play with live crabs because the big pliers of crabs will pinch people, but children have a strong interest. So we designed this activity to provide conditions for children and create opportunities for them to explore.

Activity objectives:

1, fully experience the joy of exploration activities.

2. Understand the shape and crawling direction of crabs and learn some simple observation methods.

3. Encourage children to explore bravely and accumulate some life experience.

Activity preparation:

1, forty little crabs and two big crabs.

2. Twenty small plastic boxes and four large plastic boxes.

3. A clip, chopsticks and gloves.

4, basin, water, dishcloth, transparent cover rice cooker, etc.

Activity flow:

1, the teacher asked: Do you know crabs? Did mom and dad let you play at home? (No) Why?

Child L: Because crabs are fierce.

Child 2: It has big pliers.

Toddler 3: Pinch someone.

2. The teacher said: Will the teacher play crab with you today? (OK) But be sure to pay attention to the crab's big pliers.

Children observe crabs:

Children 1, just watch and don't do it.

Baby 2, I tried to touch it with my hands, but I stopped halfway.

Baby 3, touch it with your hand and shrink it immediately.

Child 4, pick up the chopsticks on the side and play. If you catch a crab, you will bark. Laugh when it falls.

Children are sitting on the carpet.

The teacher asked: Did you have a good time? (happy)

The teacher said: Small animals bring us happiness. They are our good friends.

The teacher asked again: What does a crab look like?

The children spoke freely and the teacher listened around.

Baby 1, with a shell on his back, is grayish black.

Baby 2, with eyes, turns red when cooked.

Baby 3 has three feet.

Baby 4, no, it has four feet.

4. The teacher said: How many feet does a crab have? Let's count.

5, the teacher demonstrated, put on gloves to catch crabs.

Teacher reminds: You can catch the crab in a small box and take a closer look at what the bottom of the crab looks like.

6, washbasin, water, dishcloth, transparent cover two electric cookers, etc.

Children's courage, intelligence and ability have been improved to varying degrees in the activities. In addition, teachers purposefully guide children to observe in many ways and learn some scientific knowledge, so that children can be smarter in future exploration activities.

However, during the activity, I think it is more difficult to count live crab legs, so I can wait until the crabs are cooked.

Expert comments:

It may be more appropriate to list this activity as a life activity. From the whole process, there are not too difficult knowledge points, but the teacher puts the spirit of exploration in the first place, which reflects the desire of large class children to learn and is worth learning from. Kindergarten teaching activities do not necessarily have many difficulties to break through every time, as long as they can stimulate the desire for knowledge, sprout interest in learning and develop good study habits, such activities are good activities.

Reflection and discussion:

This activity was designed for small classes, but now it is designed for large classes. What modifications and additions do you think should be made?

2. Each group of children shows their achievements.

Teacher: What's that on your desk? What changes have taken place?

Third, talk about the used rope.

Teacher: What did you do just now?

What rope did you use? Teachers and children summarize the use of ropes together, so that children can understand the characteristics of various ropes.

For example, cotton rope is very soft, and it doesn't hurt to hit the face: nylon rope is relatively strong and can be used to hang heavy objects; Plastic rope is used to jump rope …

Fourth, play with the rope.

Teacher: Ropes can also be used for playing. I have some ropes here, and everyone is too few. You can play a rope with a few good friends and see which children can play new tricks with the rope.
