With the improvement of people's living standards, parents provide more and more nutritious food for their children, 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 created the teaching material "Little Bean's Travel" and designed this activity.
Activity objectives:
1, let children know the function of digestive organs and the process of food digestion and absorption in human body 2, learn simple self-protection methods 3, and cultivate children's good diet and hygiene habits;

Question: Where is the little bean? What do you see?
(2) put the second paragraph to understand the function of the stomach.

Conclusion: In the future, we should pay attention to eating less cold and hard things, snacks, unclean things, too much and not hungry. We should have a big breakfast and drink less cold drinks.
The goal of this part is to let children know that bad eating habits will make the stomach sick on the basis of understanding the function of the stomach. (3) Put the third paragraph and ask: Where did Adzuki go? (Small intestine) What's the use of small intestine?
What does the bean see in the small intestine?

Question: Where did the little bean go?
What's in the large intestine? What is residue? Can you keep the residue in your body for a long time?

Second, find the order in groups. We know the purpose of each digestive organ. Now, the teacher has prepared a set of pictures for each group of children to show the working condition of each digestive organ. Please cooperate with each group of children and arrange them in the order of the trip of the little beans just now. Then, tell me why this arrangement is made.
On the basis of observing the pictures, this paper discusses how to protect the digestive organs;
How to keep teeth sharp?
(2) There is a small lock beside the esophagus, which is generally closed. Talking while eating will choke food in the trachea.
(3) The residues in the large intestine are all dirty things, so wash your hands after defecation.
The goal of this part is to further understand the function of each organ and the order of digestion through images. (3) Take a quiz on health knowledge and divide the children into four groups.
Prepare some pictures, some are right and some are wrong. When the teacher shows the picture, answer right or wrong immediately. Why? He who answers many questions is the winner.

2. Help children understand the meaning of the pictures on the chessboard.

Activity evaluation:
The content selected in this activity is close to children's life and is welcomed by children. In the first part of the activity, I vividly expressed the course of food travel and the harm of bad living habits to digestive organs through what I saw and heard when I went to Tao Tao with a small bean that had not been chewed. The knowledge capacity is large, but the children are very involved in animation and unconsciously accept it. In the second and third parts, I manually sorted out the digestion chart, so that children can further understand the order of food travel and the functions of various digestive organs. And through careful observation of the pictures, we can find the problems that should be paid attention to when eating. The fourth part of the activity is intended to let children know the function and function of digestive system and let them pay attention to their daily hygiene and eating habits. This part of the content plays a role in consolidating and extending. In order to make children's knowledge into their daily behaviors and form habits, I designed an expansion activity-playing healthy behavior chess. The whole activity adopted various forms, which realized the alternation of static and dynamic, fully mobilized the children's various senses, and the children's initiative was strong, which also reflected the leading role of teachers, making the information conveyed to the children by the activity very scientific and interesting.
Attached story: Little Bean's Travel I am Little Bean, and I am willing to serve children. Today, I'm going to visit Tao Tao's body. Look, the mouth has been opened. Wow, Tao Tao's teeth are really sharp. My friend 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? I am now squeezed into a long and thin tube, which 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? " "Yes, Brother Stomach." "How did you get down at once?" "Yes, your little 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 what he eats, but he eats a lot of things 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 is like this now, and it is uncomfortable when you are sick. " I came to my little sister's house again. My sister's house twists and turns like a maze. There is a lot of fluff on the side and a small door. "I am a small intestine sister, welcome your food friends. When you go out from my little door, you can reach Tao Tao's whole body, make him grow taller and fatter, and give him 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 the elder sister of the large intestine." "Why am I surrounded by dirty things? Who are they? Where are you going? " "They are residues, and they will be excreted." "What about me?" "You will also be excreted." "Then I'm tired of working for Tao Tao." "That can't be helped, because if you haven't been chewed up, you can't become nutrition and be absorbed by your body." 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.
