Prepare courseware, tables and interesting exercises for activities.
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?

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.
Top-quality course of science in large class: animal self-defense stunt
Fan wener, science teaching plan for kindergarten large class: animal self-defense skills teaching plan
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. 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!
Fan Wensan: Interesting shadow lesson plans.
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 for playing 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.
