Design intent: With the improvement of living standards, children's diet is becoming more and more nutritious, but there are still some children who can not eat well, and children's health is not guaranteed, because many children have some bad dietary hygiene habits, such as: skipping breakfast, drinking a lot of drinks, eating cold drinks, and defecating from time to time. In order to make children understand the process of digestion and absorption of physical objects in the body, develop good eating habits, and learn to protect their health, "Little Bean's Travels" was created and this activity was designed. Objective 1: Let children understand the function of human digestive organs and the process of food digestion. 2. Cultivate children to develop the habit of hygiene. 3. Guide children to initially establish an interest in understanding and exploring the mysteries of the human body. 
Add ** notes, no more than 140 words (optional) Activity preparation: multi** courseware, peanut activity process.
1. Trigger the hobby of exploration: Teacher: We have to eat every day, so what about the food we eat? Today, let's take a trip through the human body with a small bean and see where the food it eats passes through. (Combined with the demonstration of multi** courseware to read the story of "Little Bean's Journey") ask: Little Bean's journey, first**, then through**, and finally through**? The second time to completely see the overall demonstration of the courseware) Second, through the partial demonstration of the courseware, further know the process of bean (food) travel, and a preliminary understanding of the role of the mouth, esophagus, stomach, small intestine, and large intestine, and improve children's awareness of self-protection: 1. What is the first stop of the little bean trip? How does food change in our mouths? How so? (Guide children to observe and feel each other in the process of eating peanuts) 2. The role of teeth is really great, how should we protect our teeth? 3. After passing through the mouth, the food travels to the stomach, what does it go through to the stomach? (Guide children to feel the role of the esophagus and its position in the human body in the process of drinking water) 4. What happens to food in the stomach? How so? Summary: The stomach is like a pocket, and the peristalsis of the stomach is to grind the food in the pocket into a finer and worse place, so that it is easier for the human body to digest. 5. Think about it, what will happen if there is too much food in this pocket? Have you ever had an upset stomach before, how could it be? What should we pay attention to in our lives? How can I protect my stomach? 6. Xiaodouzi's trip just now passed through the mouth, esophagus, and stomach, and it is going to travel again, what is the next stop? (Guide children to understand the role of the small intestine) Summary: The small intestine is like a processing plant, absorbing all the nutrients of food. 7. What about the last food to travel? (Guide children to understand the role of the large intestine) Summary: Food waste enters the large intestine and finally discharges the human body. 3. Game link: 1Sort the oral, esophagus, stomach, small intestine, and large intestine** in digestive order. 2.Compare the diets of the four critters to which is the healthiest. 
Add ** annotation, no more than 140 words (optional) 4. Expansion: Arouse children's love for science and grow up to explore the enthusiasm of science: In our human body, in addition to food travel, there are many secrets, as long as we learn our skills seriously, we will be able to explore more secrets of the human body when we grow up. "Little Bean's Journey": I'm a little bean. I put my companions and I carried into the mouth of a child. The child had two rows of neat teeth in his mouth. Many of their companions were chewed with their teeth and mixed with saliva in their mouths. The kid ate so fast that I went into the esophagus with the rest of the group before I could chew it. I slipped down my esophagus, and this gourd was the stomach. The stomach kept moving and secreting gastric juice, and the chewed companions turned into porridge-like mush. I turned in my stomach for a few hours, and it was still a good watercress. Later, I followed the porridge paste to the small intestine. The large intestine excretes dregs. Together with the scum, I ran out of the ** along the large intestine. And so, I traveled in vain in the child's body.
