Health Teaching Plan for Large Kindergarten Classes "The Digestion Process of Food" 1 1. Activity Background
With the improvement of people's living standards, parents give their children more and more nutritious diets, but there are still many parents who complain that their children can't eat well and their health can't be guaranteed, because many children have some bad eating habits, such as skipping breakfast, drinking a lot, eating cold drinks and defecating irregularly. In order to let children know the process of food digestion and absorption in the body, develop good eating and hygiene habits, and learn to protect their health, I designed this activity.
Second, the activity objectives
1, understand the process of human digestion of food.
2. Develop hygiene habits.
3, a preliminary understanding of the mystery of the human body, interested in the human body.
Third, activity preparation
Multimedia courseware, food, operation materials, one hand.
Fourth, the activity process
Stimulate interest in exploration:
Teacher: We have to eat every day, so where is the food we eat?
How does food travel in the human body and where does it go?
(It is the first time to watch the whole demonstration of the courseware)
Question: Where do you go for food travel first, then, and finally?
(watch the whole demonstration of the courseware for the second time)
(2) Through the local demonstration of courseware, we can further understand the process of food travel, preliminarily understand the functions of mouth, esophagus, stomach, small intestine and large intestine, and improve children's self-protection awareness;
1. What is the first stop of the gourmet tour?
How does food change in our mouth? How did it happen?
(Guide children to observe each other's feelings while eating food)
2. The role of teeth is really great. How to protect teeth?
3. Where did the food go after passing through the mouth, and through what did it enter the stomach?
(Guide children to feel the function of esophagus and its position in human body when drinking water)
4. What happens to food in the stomach? How did it happen? (Fu Zi: peristalsis)
The stomach is like a pocket, its peristalsis is to grind the food in the pocket more finely and rotten, which is convenient for human digestion.
5, children think about it, if there is too much food in this pocket, what will happen? Have you ever had an upset stomach before? How did it happen? What should we pay attention to in life? How to protect the stomach?
Don't eat too hot food, eat regularly and quantitatively, don't do strenuous exercise before and after meals, have a variety of foods, and don't eat too many cold drinks and snacks.
6. Just now, the food passed through the mouth, esophagus and stomach. It is going to travel again. What's the next stop? (Guide children to understand the function of small intestine)
The small intestine is like a processing factory, absorbing all the nutrients of food.
7. Where will the last food go? (Guide children to understand the function of large intestine)
Food waste enters the large intestine and is finally discharged from the human body.
(3) Application exercise: judge where food goes and further understand the functions of mouth, stomach and small intestine.
Organize pictures through children's operation and review the process of consolidating food travel.
(d) Development: Stimulate children's love for science and their desire to grow and explore science.
In our bodies, there are many secrets besides food travel. As long as we study our skills carefully, we will explore more human secrets when we grow up.
Verb (short for verb) activity is over.

The health teaching plan "Food Digestion Process" for large classes in kindergarten 2 Activity objectives:
1, to understand the functions of various digestive organs in human body and the process of food digestion and absorption.
2. Cultivate children's good eating and hygiene habits and learn simple methods of self-protection.
Activity preparation:
1, PPT Food Digestion Process
2, digestive chart, digestive organ pictures
3. Four health knowledge cards, two picture cards (√, ×) and candy digestion chess.
Activity process record
Design intent:
Nowadays, children have many problems in diet. Many parents complain that their children don't eat well and their health is not guaranteed. The reason is that many children have some bad eating habits, such as eating while playing, overeating, eating cold drinks and snacks. In order to let children understand the process of food digestion and absorption in the body, develop good eating and hygiene habits, and learn simple self-protection methods.
Activity flow:
First, read PPT completely and know the names of various digestive organs.
There are so many rich foods in the picture. Do you want to eat? After eating these foods, where do you think they will go? Today, a adzuki bean will take us on a trip to the digestive organs. After the trip, we will know where the food we ate went.
Second, look at PPT in sections to understand the functions of various digestive organs.
1, observation picture-oral cavity
Question: ① Where did the small beans enter? (oral cavity)
2 What happens when you put it in your mouth? (chewing teeth)
2. Observation picture-esophagus
Question: ① Where did the small beans go after being chewed? (esophagus)
What is the esophagus like? (Slender tube sample)
③ What is the function of esophagus? (conveying food)
3. Observation picture-stomach
Question: ① What is the stomach like? (pocket)
② What is the function of the stomach? (further grinding food)
(3) What does adzuki bean see in his stomach? (My stomach is upset)
④ Why does the stomach get sick?
4. Observation picture-small intestine
Question: ① Where did adzuki go? (small intestine)
② What does the small intestine look like? (winding like a maze)
③ What is the function of small intestine? (Absorb the nutrition of food)
(4) Why doesn't the little bean go out through the small door? (Not chewed)
5, observation picture-large intestine
Question: ① What does it look like? (thick and short)
② What's in the large intestine?
③ What is the function of the large intestine? (Store food scraps)
(4) What is residue? Can you stay in your body for a long time?
Conclusion: Our children should defecate regularly.
Third, grouping arrangements to consolidate the role of various digestive organs.
1, to help children recall the digestive organs in Mao Mao;
2. The children are arranged in groups to deepen the impression;
3. Teachers and children organize maps together, find the correct travel route of adzuki bean, and verify whether each group of maps is correct.
Fourth, divide into four groups and discuss health knowledge.
1, show four pictures, namely: drinking, drinking more boiled water, washing hands before meals, eating and talking, and discuss one picture in each of the four groups.
2. After discussion, post good behaviors under √ and bad behaviors under ×, and judge a picture for each group.
5. Discuss how to protect the digestive organs.
1, oral cavity-don't eat hot things.
2, esophagus-don't talk when eating, so as to avoid food choking on the organs.
3, stomach-eat less cold, hard food, chew slowly, can not exercise immediately after meals.
4, small intestine-exercise more, strengthen the absorption capacity of small intestine.
5, large intestine-residue is formed by dirty things, so wash your hands before and after meals.
Sixth, expansion activities: candy travel chess (chess points are digestive organ maps)
Ok, the teacher has prepared candy travel chess for everyone in the classroom. Let's go back to the classroom and play together!

Digestion process of food
Hi! Hello everyone! I am a small bean with rich nutrition. Today, I'm going to visit Mao Mao's body. Look, the mouth has been opened. This is the mouth. Wow, Mao Mao's teeth are so sharp that my friends suddenly turned into pieces. Look, they are all going down. After a while, I will go down to pieces, too. Hey! How did I get squeezed down? As soon as I left my mouth, I was squeezed into a long and thin passage, that is, the esophagus. The esophageal wall is so thin that it may be punctured if it touches a fishbone. I was sent down the esophagus bit by bit.
I am in a big pocket now, and this pocket is my stomach. It keeps turning like a mill. My friend has been spinning around here, grinding and grinding, becoming like paste. "ouch! Who is it, physically hard? " "Yes, big brother's belly." "How did you get down at once?" "Yes, the young master ate too fast and let me down without chewing me up." "Hey, belly eldest brother, how do you have a wound? Does your wound hurt? " "That's to blame my little master. He usually doesn't pay attention to eating. He eats as much as he likes, which makes me very uncomfortable. He drinks cold drinks and boiled water for a while, which makes me miserable. Sometimes I really want to have a rest, but the young master wants to eat snacks and stuff something in it to let me continue my work. I am really exhausted. Therefore, it has become like this, and it is uncomfortable when you are sick. "
I came to my little sister's house again. Miss Jie's house is 5-7 meters long, with a lot of fluff on the side and a small door. "I am a small intestine sister, welcome friends who eat goods. Going out from my small door can reach Mao Mao's whole body, make Mao Mao grow taller and fatter, and give Tao Tao strength. " "I also want to go out and do something for Tao Tao. Hey, why can't I get out? "
"Hey, little bean, come to me." "Well, who are you?" "I am a big sister." "Why am I surrounded by dirty things? Who are they? Where to go. " "They are residues, and they will be excreted." "What about me?" "You will also be excreted." "Then I haven't worked for Mao Mao." "That can't be helped, because if you haven't been chewed up, you can't become nutrition and be absorbed by your body." It turns out that what we enter is the large intestine, 1.5 meters short and thick, which is responsible for absorbing water and storing residues. After I go out, I must tell my children what I have seen, so that they can develop good eating habits and make them healthier.
