Design intent:
Playing is a child's nature. Children like to travel. Every time they come back from a trip, they want to tell their teachers and friends what they have seen and interesting things. Combined with children's needs and interests, our class launched the theme of "Happy Travel". With the continuous extension of activities, once the children were whispering in a meal, the teacher squatted down and listened carefully to the children's conversation, only to know that they had a new "discovery": Will food "travel" in the stomach? What an interesting question! The children are watching.
The outline points out that science education should be closely linked with children's real life, and things and phenomena around them should be taken as the objects of scientific inquiry. There are all kinds of food in life, and children always have endless food. In order to satisfy children's curiosity and desire to explore, the theme activity of "Gourmet Travel" was launched. In order to reflect the spirit of the new curriculum reform, we adopt the concept of integrating myopia, so that children can understand the digestive organs and food digestion process of the human body, and at the same time focus on the relationship between stomach and health, and improve their awareness of self-protection. At the same time, cultivate children's observation and cooperation ability. In order to really arouse children's interest in participating in activities, I pay attention to the flexible use of teaching methods: First, set the question situation (starting from children's curiosity-"Where is the food?" ) observation method (using children's eyes to discover the digestion process of food in human body) operation method (using children's favorite operation form-making puzzles and "building" digestive system diagram) and so on. In order to better highlight the key points and break through the difficulties, we give full play to the role of multimedia teaching methods and make our own courseware to make our learning activities more concrete, vivid and interesting.
Activity purpose:
1, know the main digestive organs of human body, understand the digestion process of food, and focus on the relationship between stomach and health.
2. Deepen children's understanding of the body and improve their awareness of self-protection.
3. Cultivate children's observation and cooperation ability.
4. Stimulate children's willingness to explore the fun of scientific experiments.
5. Be able to boldly carry out practical activities and express your views in complete language.
Activity preparation:
1, multimedia courseware, several sets of human digestive system cards, a rabbit puppet, food, whiteboard paper, oil pastels, plastic hoses and other materials.
2. Discuss with mom and dad before class to find relevant information.
3. Creation of theme environment (mannequin, various structural diagrams of human body, etc.). )
Activity flow;
First, the teacher and the child each eat a piece of radish, and ask questions to let the children guess, which leads to the topic of "gourmet travel".
1. Tell the story "Journey of Radish".
2. Ask the key question with a rabbit puppet: Where have all the radishes passed?
Second, children choose their own food (sugar, cake, fruit, etc.). ) and experience the feeling of food in the body again.
Third, know the main digestive organs and understand the digestion process of food.
1. The teacher demonstrates the courseware to help children know the names of digestive organs.
2. Pay attention to the relationship between the stomach and health: let children understand the harm of bad eating habits to the stomach.
3, combined with children's life experience, guide children to discuss: What are the healthy eating behaviors? What are unhealthy eating behaviors? Educate children to have a sense of self-protection.
Fourth, group operation activities: deepen the understanding of the main digestive organs of the human body.
1. Play jigsaw puzzles in groups. Children draw a complete picture of human digestive system with small cards.
2. After some children lie down and outline the human body, they choose plastic hoses of different sizes (for esophagus, stomach, small intestine and large intestine). ).
3. Sharing and communication: Teachers and children will arrange the completed map of human digestive organs in the indoor theme column.
Attached story: the journey of radish
Rabbits like radishes best. The rabbit chewed me in its mouth, and I itched. I accidentally swallowed it. After a while, I was in a long tube, just like sitting on a slide. Very interesting! I slipped into a big bag before I had enough fun. This big bag is amazing. It will secrete some liquid, and at the same time it will creep slowly, grinding me more and more broken, more and more broken ... After being ground, I walked into a winding small tube, like a maze, and finally came out. I walked to a crumpled big tube and all my nutrients were absorbed.
