Design of lesson plans for preparing lessons for scientific activities in kindergartens

Activity purpose:

1, guide children to try to do small experiments, so that children can initially perceive some scientific phenomena such as "evaporation of water vapor" and "how rain is formed".

2. Understand the relationship between rain and human beings.

3. Stimulate children's interest in observing, discovering and exploring nature.

Activity preparation:

1, puppet table, puppet rabbit, rabbit mother.

2. Alcohol lamps, beakers, glasses, glasses and matches.

3. Projector, the story "A Drop of Water Travel", related slides and tapes.

Activity flow:

First, teachers perform puppets and try to ask questions

The teacher took the rabbit out to play with his mother. Suddenly it rained. The rabbit asked his mother, "Why does it rain?" The story leads to the topic and asks the question: "Children, do you know why it rains?"

Second, children do small experiments (children try for the first time, group activities)

1. The children lit the alcohol lamp and heated the water.

2. The teacher asked the question of trying: Look carefully, what do you find?

3. Summary: When the water is hot, there will be water vapor, and the phenomenon that a lot of water vapor runs upward is called "evaporation".

4. Discussion: Have you seen the phenomenon of "evaporation"?

(divergent thinking)

Third, observe the phenomenon that water vapor turns into small water droplets when it is cold.

1. Please touch it. Is the glass plate cold or hot?

2. Pour hot water into the cup and ask: What comes out of the cup? (water vapor)

3. What will happen if the cup is covered on the teacup?

Why are there small drops of water on the glass? The experimental results show that water vapor will become small water droplets when it is cold.

Four, slide show (through intuitive teaching, focus on understanding the scientific phenomenon "why it rains")

1, the sun is a big fireball, it is like a strange stove. Clothes, handkerchiefs, rivers and water in the land are turned into steam by the sun. Where did all this steam go?

2. Ask the children to listen to an interesting story "The Journey of Little Water Drops" (combined with slides).

Please tell the little secret "Why is it raining in the sky" to Mother Rabbit and Little Rabbit.

5. Understand the relationship between rain and human beings

1, please try to tell the benefits of rain.

2. Let the children try to talk about the danger of rain.

3. Summarize the harm of the benefits of rain told by children, educate children to learn from the knowledge and skills of primary schools, grow up to be scientists, and let rain do more good things for mankind.

(2) Bridge designers

Teaching objectives:

1, through children's own observation of experimental phenomena, cultivate children's orderly and patient good observation habits and keen observation ability.

2. Cultivate children's interest in understanding and exploring the scientific principles contained in common things in life.

3. Cultivate children's ability to solve problems through their own operations.

Teaching preparation:

Prodigy computer software, bridge exhibition, pen and paper.

Teaching process:

First, arouse children's interest in the form of stories:

There is a small ditch in front of the bear's house. It's worried about what to do to cross the other side. Children, can you help bear find a way? Little bear's good friend, the clever monkey, also helped him think of a way. Let's hear what it is. Is it what we think?

Second, ask questions while watching prodigy software:

1. Where do smart monkeys and bears come from? What bridge do you see? What did ancient people use to build bridges? Does bear like it? Why?

2. Which bridge did the clever monkey and bear come to? What was Zhao Zhouqiao built of? What is its shape? What's the difference between Zhao Zhouqiao and Zhu Qiao?

3. What bridge did they see when they came to modern times? What is the steel suspension bridge made of? What's special about reinforced suspension bridge in structure? What is the function of reinforced suspension bridge? Which steel suspension bridges have you seen now?

4. After seeing the steel suspension bridge, what bridge did they see? Where is the modern overpass built? What is it made of? What role does it play in traffic? Where do you see the modern overpass?

Besides the ancient bamboo bridge, Zhao Zhouqiao and modern steel suspension bridge and overpass introduced by the clever monkey, what other bridges have you seen?

6. Let's get into the computer and look at some bridges with different materials and different uses.

We have seen so many bridges, which one do you like best? Why?

Bell wants to build a bridge now. I want to ask children to be a small bridge designer and help bear design a bridge, ok?

Five, children design bridges.

6. Ask some children to introduce his design works to everyone, and finally give them to the bear.

Exploring knowledge: how does information spread?

1, activity target:

1) Children can actively collect and transmit information from different channels and in different ways.

2) Children learn about different information transmission channels in activities and learn to use different information tools.

2. Activity preparation:

Children learn relevant knowledge by asking and interviewing.

3. Activity flow:

1) Communication: I know the way of information transmission. Children can be inspired to consider the following aspects: signaling with objects, signaling with sounds, and signaling with words. Such as: sending signals through gestures, semaphores, fireworks and other objects; Send signals by blowing horns, ringing bells, drumming, broadcasting telephones, etc. ; Send signals by carrier pigeons, post office delivery, fax, e-mail, etc.

2) The teacher uses pictures to tell the story of people transmitting information. For example, fireworks were set off on the beacon tower of the Great Wall in ancient times to convey the enemy's situation; During the War of Resistance against Japanese Aggression period, the enemy's whereabouts were reported by knocking down the message tree.

3) Discussion: How do people convey information nowadays? Guide children to understand common communication tools.

4) Organize children to play communication games and make phone calls: The teacher divides the children into two groups and whispers to the first person in each group. After the start, they will be sent back one by one, and the last one in each group will report the phone content. The team that passes quickly and accurately wins.

4. Activity expansion:

1) Organize children to operate computers by themselves.

2) Provide semi-finished materials in the activity area, learn to make these communication tools, and provide props for children to play role games.

(3) Interesting shadows

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.

Top-quality course of science in large class: animal self-defense stunt

(D) the self-defense tactics of animals

Default target:

1. Discover several self-protection methods adopted by animals in order to survive.

2. Germinate an interest in exploring the mysteries of animals.

3. Further deepen the understanding of animal self-protection through physical performance.

Activity preparation:

1, multimedia courseware, music.

2, small animal headdress, "tail" woven with crepe paper, 4 jelly bottles.

Activity flow:

First, the game: hide and seek.

1, let's play hide and seek. Let me count 1, 2, 3 children hide.

2. Discussion: Why do I find some children and I can't find some children?

3. The teacher's summary.

Second, the stealth coup.

1, learn about the stealth tricks of small animals.

Teacher: Small animals are also playing hide and seek. Please look carefully and tell everyone what animals you have found and where you are hiding.

Watch the courseware: the animation of butterflies flying to the branches, lizards lying on the mound and frogs drilling into the grass. )

2, physical performance: dead leaves butterflies fly to the branches.

Lizards lie on the mound.

The frog got into the grass.

3. What skills do these animals have to protect themselves?

Summary: Invisibility. In nature, in order to protect themselves and survive better, some animals' body colors and stripes are very close to their living environment to hide themselves and avoid enemies.

4. Inspire children to tell which animals have stealth skills?

Third, discuss the unique skills of animals in self-defense.

1, do you know what other ways animals can protect themselves?

2. Look at the courseware. Before reading, ask, "Notice which animals are in it, and how do they protect themselves?"

Question: What kind of animal do you see and how does it protect itself?

Name one and click on the corresponding word baby and the head of the corresponding animal. )

Armor: tortoise

Hard thorn: hedgehog

Running: deer

Self-cutting: Gecko

Smell: Weasel

Play dead: fox

3. Discussion: What other animals protect themselves in the same way?

Summary: Small animals are very smart. They thought many ways to protect themselves, some-some-and so on. They are really powerful little animals.

Fourth, self-defense.

The teacher showed all kinds of animal headdresses. Who did the children answer? How do you protect yourself?

Now let's play a game. Children can become any kind of small animals. Wear headdress and play music. Hey! What happened? The tiger is out, what should we do? You have to become a small animal to protect yourself and see who imitates the most!

Science teaching plan for big class: interesting crabs

(5) 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?

(6) changeable weather

moving target

1. Stimulate children's interest in observing weather.

2. Understand the common weather conditions and know how to understand the weather conditions.

Understand the relationship between the weather and our life, and try to design a weather forecast table.

Activities to be prepared

Courseware and forms

Activity process

First, understand the relationship between meteorology and military affairs.

1. Let the children enjoy a short story "Grass Boat Borrows Arrows" first.

There is a very clever man named Zhuge Liang in the story. He used the weather to make 654.38 million arrows in three days. How did he do it?

2. Let children think through stories. How did Zhuge Liang know it would be foggy?

Second, understand the common and bad weather conditions, and know how to understand the weather.

1. Besides foggy days, what other common weather do you know?

2. Know some bad weather conditions. And watch courseware.

How do you know the weather?

(SMS, TV, newspaper, etc. )

Appreciate a weather forecast and know its main contents.

Weather, temperature, dressing index, etc. )

Fourth, understand the relationship between the weather and our lives.

1. Interesting question and answer

Teacher: The weather has a lot to do with our life. I will test you today.

(1) How to escape the heat in hot weather?

(2) How to maintain yourself in thunderstorm weather?

(3) What do you need to prepare when you go out in rainy days?

Five, try to design the weather forecast table.

Teacher: The weather is closely related to our life. So we should care about the weather and learn to maintain ourselves according to the weather changes.

The teacher prepared a table for everyone, with three columns: weather, temperature and warm tips.

2. Let the children be weathermen and record the weather on the form.
