1 the goal of "ant" activity in small class science teaching plan in kindergarten
1, by observing ants, understand the role of ant tentacles.
2. Cultivate children's ability to observe and think.
Activities to be prepared
1, Ppt: the characteristics of ants.
2. Figure: Ant 4.
Activity process
First of all, the pictures of ants arouse people's interest.
1, Teacher: Look at the pictures, children. (ant)
Do you know what ants are doing?
2. Inspire children to imagine boldly and encourage them to express their ideas.
Second, courseware demonstration: the characteristics of ants
1, children want to know how ants grow up?
(Let the children discuss with each other)
2. Watch the courseware demonstration to understand the growth process of ants.

Third, question inquiry: What is the function of ant tentacles?
1, discussion for children
(1) What's the use of ants' tentacles?
(2) Can ants have no tentacles?
2, the teacher explained that the role of ant tentacles.
(1) The tentacles of ants are brighter than the bamboo poles of the blind.
(2) The antenna has two functions:
One is the tactile effect, through the contact between the antenna and the outside world, the outline, shape and hardness of the object in front can be found.
And the topography of the road ahead.
The other is the sense of smell, which is used to identify.
It turns out that when ants walk, they take glands at the end of their abdomen and legs.
Constantly secreting a small amount of chemicals with special odor, called marking substances, which are polluted on the road and leave traces.
Ants living in the same nest, far away from the nest, use special nose tentacles when returning to the nest.
Come and smell this smell, signpost. This is the so-called "olfactory navigation".
3. Help children remember
(1) You can't find a home without tentacles.
(2) You can't find food without tentacles.
4. Game: Ants look for food.
Children wear headgear with tentacles to play ants, climb out of the house to find food, and move home when they find it.
Tell your partner to take food with your tentacles.
The goal of "ant" 2 activity in small class science teaching plan in kindergarten;
1, encourage children to observe small ants independently in the process of finding, watching, speaking and doing.
2. Understand the characteristics of ants, where they live and what they like to eat.
I am willing to tell you my thoughts boldly.
4. Obey the rules of social behavior and don't do anything "forbidden".
Activity preparation:
Ask the children to prepare food (candy, biscuits, etc.). ) The ant liked it beforehand, and there was a magnifying glass.
Activity flow:
First, dialogue leads to activity.
1. What food did you prepare for the little ant?
2. Where does this little ant live? Let's go find them together and bring them delicious food.
Second, find ants.
1, lead the children to the community park and let them find the little ants.
2. Where did you see ants? What is it like?
Third, feed the ants
1. Let the children give the prepared food to the ants and see what the ants like best.
2. Guide children to talk to ants.
Such as: small ants come to have a taste; Does it taste good? What does the little ant seem to say? It's delicious, thank you. )
3. What else did you see? What's new?
4. Let the children walk and see what ants like to eat best.
Say goodbye to the ants, take the children back to the garden, and the teacher will make a summary.
Small Class Science Teaching Plan "Ant" 3 Kindergarten Goal:
Understand the living habits of ants.
Prepare:
1, biscuit crumbs, sugar, condiments, rice grains, etc.
2, recording paper, pen,
3, ant courseware, black paper, bottles
Process:
First put all kinds of things to attract ants.
Put all kinds of things outside the house to attract ants
Second, observe the dynamics of ants and record them.
1. Where are the most observed ants? What are the ants doing?
2. Record their findings.
Third, communicate their findings.
1, communicate the situation of each ant.
2. Discuss whether ants have their own homes and how they will transport the food they find. How do they inform their friends?
Third, after reading the courseware, understand the living habits of ants.
Fourth, extended activities: small experiment "ants settle down".
Put some ants in a bottle full of soil, and first observe what the soil in the bottle is like. Then wrap the bottle with black paper and observe the changes of soil after a few days.
It is pointed out in the syllabus of the small class science lesson plan "Ant" in kindergarten that science education should be closely linked with children's real life, and the things around them and imagination should be taken as the objects of scientific inquiry. Teachers grasp the characteristics that kindergartens like to play with water, and create game situations, so that children can stimulate their curiosity and desire to explore through observation and exploration, and help them initially understand the ups and downs of objects. Let's take a look at Little Ants Crossing the River in kindergarten class.
Small Class Science Teaching Plan "Little Ant Crossing the River" in Kindergarten
Activity objectives:
1, get a preliminary understanding of the ups and downs of objects and stimulate children's interest in exploration and discovery.
2. Experience the fun of playing with water and be interested in operational activities.
3. Learn to simply classify and record sinking and floating objects.
Activity preparation:
1, wooden blocks, stones, foam, snack plates, keys, toys (children's operating materials).
2. Record a picture of a paper hand and ants crossing the river.
Activity flow:
First, situational introduction
Teacher: It's a beautiful day today. The little animals came out to play. Look, who is this? (ant)
Teacher: Little ants are crawling and hungry. When he found an apple tree in the distance, he climbed over, but a river appeared in front of him. Please help the ants find a way to cross the river.
Second, understand the ups and downs.
1. When the teacher does the experiment, put stones first.
Teacher: "Look, who can use these materials to help ants cross the river? Let's try the stone first. "
Q: What did you find? What happened to the stone?
The teacher concluded: Because the stone is heavy, it will fall into the water. This phenomenon is called "sinking". Can sunken materials be used as ants' boats?
The teacher did the experiment for the second time and let out the bubbles.
Q: What did you find?
Teacher's summary: Because the foam is relatively light, it will float on the surface and will not fall down when put in water. This phenomenon is called "drifting". Now we put the little ants on it. Did you see it cross the river?
3. Consolidate children's understanding of ups and downs.
We saw just now that if you put it in water, heavy things will fall. We call it "sinking" and will not fall. We call it "floating".
(Activity reflection: From this perspective, children can specifically express the ups and downs and are also very interested in this activity. However, in the process of comparing stone and wood for children, because the materials used are unreasonable, the stone is too small, but the wood is very big, which interferes with children's vision. So some children think that wood is heavier, which makes it impossible for children to accurately judge: which is heavier, stone or wood, which will sink. If you choose a stone as big as wood, the child can see at a glance that the stone is heavier. So we won't waste too much time on this link. )
Third, children operate and record the operation results.
1. Children's cognitive materials
Teacher: Now please ask the children to help the ants find a way. Look, the teacher has prepared a lot of materials for you. What do you have? Please try all kinds of materials to see what can float and be used as an ant boat.
2. Put forward the operation requirements and recording methods.
Teacher: When playing, the teacher also prepared a record sheet for the children. If this material floats, please stick a sticker on the water. If it sinks, please stick a sticker on the water.
3. Children's operation and teacher's guidance record
Fourth, teacher evaluation.
1. The children are all ready. Let's have a look.
2. Teacher verification
(activity reflection: judging from the recorded results, most children can accurately record the ups and downs. Among them, there are differences in the experiments of plate materials. Some children record that it is heavy, and some children record that it is floating. I take this opportunity to conduct random education and let two children with different grades operate on the spot. Why do you think it is heavy? Are you floating? Two children use the same materials, why are the results different? Through field experiments, let children know that the results are different because of different ways of playing, and make good use of educational opportunities to give them correct guidance. However, in terms of children's use of the record card, because the design of the record card is not reasonable, some children put up the whole record card, and they simply can't see whether it is heavy or floating; If the teacher draws a middle line in the middle of the basin, which means sinking above the middle line and floating below it, the problem of unclear results will be easily solved. )
