Design intent:
Children in small classes are curious about everything, and they will actively explore things they are interested in in in their own way, such as tearing, rubbing and stepping on. The children in my class suddenly became interested in camellia leaves in front of the corridor while watching their brothers and sisters do exercises. They picked leaves while the teacher was not looking, and some children quarreled about it. I find that oral education is not effective in reminding children, but I still choose.
Activity objectives:
1, concern and observation interest in plant leaves.
2. Try to classify leaves by size, color and shape in the form of games.
3. Know not to pick the leaves of plants casually.
Activity preparation: leaf wall charts, objects, leaf invitations, background pictures, etc.
Activity flow:
1, show the leaf invitation, and invite children and panda babies to participate in the leaf exhibition. (Give each child a homemade leaf as a visit ticket)
2, lead children to appreciate all kinds of leaves, and guide children to observe the shape of leaves.
3. Game activity "Find friends"
1) Sing the song of finding friends and find friends according to the color of leaves.
2) Sing songs about finding friends, and find friends according to the size of leaves.
3) Sing the song of finding friends and find friends with the same color and shape.
4. Help the baby with leaves find his mother: send the leaves on the children's hands to the background picture on the wall. Guide children to find a tree with the same leaves on their hands and allow their parents to help.
5, review children's songs: small leaves
6. Teach children not to pick leaves casually in a panda tone.
7. Invite mom and dad to the kindergarten to see all kinds of leaves and carry out leaf picking activities.
Activity expansion:
Carry out activities such as leaf classification and leaf pasting in regional activities.
Activity reflection:
I invited parents to participate in this activity, and parents played a guiding and promoting role in the process of participating in the activity. Especially at the end of the activity, the children took their parents to enjoy the leaves in the kindergarten and brought the fallen leaves back to the classroom, which reflected the good atmosphere of fun between parents and children. Secondly, the leaf invitations I prepared for children are beautiful and rich, which is in line with the characteristics of small class children. The design link is naturally compact, trying to classify it in the form of games and matching it with music songs. In the activity, I pay attention to each child's performance, actively give children the opportunity to speak and practice, effectively integrate knowledge such as calculation, language, common sense and music, and get good results.

moving target
1. Children perceive a gap in an object through operation.
2. Cultivate children's thinking mode of scientific, orderly and reasonable arrangement of space.
Activities to be prepared
Each group has a tray, an empty wide-mouth glass bottle, stones, pebbles, sand, water, spoons, chopsticks, recording paper and pens.
Activity process
First, let the children observe the experimental supplies placed on the table.
1, stone, right hand, sand and water, a spoon, a chopstick, a piece of paper and a pen with the outline of a glass bottle.
2. Talk about the difference between stones, pebbles, sand and water.
(1) Sand and water can flow. Stones and pebbles have various shapes, which are more stinging to the touch than sand, and stones are bigger and heavier than pebbles.
(2) Pebbles are bigger and heavier than sand, water is tasteless, and stones, pebbles and sand smell like mud.
(3) Water is transparent and can't be caught, while stones, pebbles and sand can be picked up by hand.
Second, the problem to explore
Can you put stones, pebbles, sand and water in a bottle? Have a try.
Children put stones, pebbles, sand and water into bottles in two ways.
(1) Install large stones first, and then install small stones, sand and water in turn.
(2) Fill it with water first, and then fill it with sand, pebbles and boulders in turn.
Third, record the experimental process.
1, tell me what I found.
(1) Install large stones first, because it takes up a large space, and then put some small stones to fill some gaps.
(2) Later, some sand was put in, and the sand filled the gaps between the stones.
(3) Finally, water is poured to fill the smaller gap.
2. Pour water first, then put sand, pebbles and boulders, without success.
Fourth, the experiment found that
1, enlarge the stone first, then put pebbles, sand and water, so that more can be loaded.
Everything should be put into a bottle, even if it is piled above the bottle mouth, it is a failure.

1. Identify and understand the characteristics of four kinds of fruits in hide-and-seek games.
2. Try to observe the common fruits from the whole to the part to improve the observation ability.
Activities to be prepared
Knowledge and experience preparation: children have a superficial understanding of the names, shapes and colors of common fruits.
Material preparation: self-made big book; Shadows of apples, pears, bananas and lemons made of black colored paper; Apples, pears, bananas and lemons made of transparent plastic paper; Apples, pears, bananas and lemons of all colors.
Activity process
First, look for the shadows of apples, pears, bananas and lemons.
1, wonderful lead-in: Today we are going to read a very big book. Let me have a look at the title, The Fruit Doll Hiding from the Cat. Can you hide and seek? How to hide? (Fun, right? ) So who is hiding here? Let's see it, shall we?
Teacher: Who is this? (Smiles) It seems to be talking. What does it say? Listen carefully. Hello, everyone. We are fruit dolls. Do you want to play hide-and-seek with us? (Page turning) Mom is here, but our shadows are hidden. Our shadow is over there Help our shadow find his mother quickly.
2. Find and post a post: Let's try, get these shadows and find their mother.
3, children's operation, teacher observation and guidance
The children put shadows on the corresponding outlines of the big books, and the teacher observed and guided them:
(1) Can children send the fruit shadow to the corresponding place according to the shape?
(2) When the child matches correctly, the teacher helps the child improve by asking questions: Whose shadow is this? What is its shape?
4. Teachers
(1) Key question: Look. Are you okay? Do you know whose these shadows belong to? How do you know this is the shadow of apples, pears, bananas and lemons? What are their shapes? Like what?
(2): The shape of an apple is round, the shape of a pear is large and a small, the shape of a banana is long and curved, and the shape of a lemon is oval with sharp corners at both ends. We found the shadows of apples, pears, bananas and lemons according to their shapes.
Second, look for the colors of apples, pears and bananas.
1, excited again: What does this smiling face look like now? It spoke again. (Imitating the sound of fruit) You are great, little friend. You found us by shape. Now look at the small envelope on the side. What's in it? But do they have colors? The color of our clothes is hidden. Please help us find the color. Let's see where the color of the fruit doll is. -What color do you have?
2. Explain the task: Look, the clothes of these fruits are all gone. Please find out their colors and what color to paste them in. Are you ready?
3, children's operation, teacher observation and guidance.
Teachers' observation and guidance:
(1) Will children send transparent fruits to the floor of the corresponding color?
(2) When the child matches correctly, the teacher helps the child improve by asking questions: What color clothes are you wearing for apples, pears, bananas and lemons?
4. Teachers.
(1) When green is not used by children, the key question is: What colors of clothes does Apple Baby have? Where have you seen apples of different colors?
(2) When some children use green apples, the key question is: Where are the green apples used? What color clothes does Baby Apple have?
(3) Different fruits have different colors. Some fruits of the same species will have different colors.
Third, look for the fruit hidden behind the door.
1, the third excitement: (imitating the sound of fruit, changing back to smiling face) The children are great! You will soon find our shadows and colors. We haven't had enough fun. Hide again. Haha, it's a little hard to find this time. But can you find us? It's really hard to find.
2, explain the task: this time apples, pears, bananas, lemons are hidden behind the door, only showing a little. Let's see who is hiding behind the door.
Children observe and judge who is hiding behind the door.
What fruit does the round shape remind you of? What fruit does the color of yellow clothes remind you of? What fruit does the long handle remind you of?
4. Teacher: Your eyes are really powerful. We only showed a little, but you recognized us. The fruit doll said that she would go to the classroom to play hide and seek. Let's take them to play.

Teaching objectives
First, let the children know that the light bulb can also be lit in salt water through the experimental operation of self-made small batteries.
Second, stimulate children's interest in exploring scientific phenomena.
Teaching preparation
One set for each person: a carbon rod and a piece of zinc, fixed on a plastic board; Beakers for water, small bulbs with clips, electric bells and spoons.
Section 2, 1 dry battery, one peeled battery.
Third, every two people have a glass of salt.
teaching process
First, show the small light bulb and lead out the battery.
Question: Is the light bulb on? Why is this happening?
Second, introduce how the battery was invented in the form of a short story.
A long time ago, there was a foreign scientist named Volt. He liked doing all kinds of experiments very much. Once, when he was doing an experiment, he put two metals into a chemical substance. As a result, something strange happened, electricity was generated here, and the world's first battery was invented.
Volt became the scientist who invented the battery. We children also like to use our brains and do small experiments. Today we are all going to be a little scientist and make a small battery ourselves.
Third, be a little scientist and a small battery.
1. Introduce carbon rods and zinc sheets with stripped batteries.
2. The teacher demonstrates how to make a small battery. Put the two clips on the light bulb on the zinc sheet and carbon rod respectively, and put them in a beaker filled with water, and the light bulb will light up.
3. Make a small battery and try it in the prepared clean water.
(1) The teacher checks whether the clip is correct.
(2) Observe whether the light bulb is on.
4. Try to add salt to the cup.
(1) The teacher makes a tour to guide and observe the children's operation.
(2) Question: How is your battery made?
A lot of salt was added just now. Why don't you shine? It takes stirring to dissolve the salt water in the water.
(3) Don't make a small battery, please try again.
5. Summary: Just now, the light bulb didn't light up in clear water without salt, but it can light up in salt water.
Fourth, interesting little bells.
1, the teacher showed the little bell clamped on the homemade small battery, and the little bell sang.
2. Friends, let's take a small bell and try it on a small battery made by ourselves. Tip: Look at how other people's clips are clamped.
3. Question: Why does your little bell ring? Why doesn't the little bell ring?
4. Summary: There are two clips on the bell, one is red and the other is black. The clip will ring only if it is clamped correctly. Why? This problem will be understood when children grow up and learn more skills.
Fifth, expand knowledge.
We made a small battery today. What other batteries do you know? (Dry battery, BB battery, watch button cell, rechargeable battery ...) These batteries are all invented by human brain. Children should think more in the future and invent various batteries when they grow up.

Teaching objectives
1, through the exploration and experiment of jujube toys. Stimulate children's interest in the phenomenon of balance.
2. Stimulate children's desire to explore.
Teaching preparation
Teachers' supplies: jujube, sorghum stalk bark, toothpicks;
Children's products: jujube. Sorghum stalk, toothpick.
teaching process
1, take a look, and say let the children have a look at the prepared materials and say what they have to arouse their interest in the activities. Jujube and toothpick are familiar items for children. Let children use dates, toothpicks and sorghum stalks as active substances. Stimulate children's interest in activities.
2. Do it and have fun.
(1) Let the children put sorghum stalk Pi Zha on a jujube and a toothpick to see if it is flat (Let the children try to put a jujube on the toothpick first, and let the children have a preliminary attempt to explore balance activities. When a child tries to use a jujube but can't put it on a toothpick, he will naturally think that there should be a jujube on the other side. )
(2) Children try to make their own jujube toys, a kind of sorghum stalk skin. Tie two dates at both ends.
(3) Have some fun. Let the children put the jujube toys on the toothpicks. Find balance and turn around. The teacher encouraged the children to operate. Explore, let the children find the answer to how to balance the two sides of the object on the basis of exploring alone. Cultivate children's interest in exploration; Develop their imagination and creativity. )
(4) Tell me how you made the jujube toy spin.
Summary: Only keep the two ends of jujube balanced. Let it spin. Children have gained a pleasant and positive experience through their own hands-on operation and exploration.
Teaching extension
Continue to explore the play of jujube toys in the game area to further perceive balance.
