Textbook analysis
Before learning this lesson, the students learned the nutrition of food, and had a clear understanding of the main nutritional components of food, knowing which nutritional components our bodies get from food, which foods provide us with activity energy and which foods keep us healthy. The inquiry learning in this lesson is based on the students' existing life experience and knowledge.
Analysis of learning situation
Students are the main body of scientific learning. Learning science should be a process in which students actively participate in the experience. Students should not be forced to instill knowledge about food collocation. By creating various scenarios and skillfully designing interesting teaching activities, students can experience the importance of reasonable collocation of diet and nutrition in food collocation. At the same time, it can cultivate students' good moral character of caring for themselves and others since childhood, and stimulate students' enthusiasm for learning science.
Teaching objectives
1. Let students know the importance of comprehensive and reasonable nutrition through catering.
2. Learn to express your research results in written language, picture language and picture language by designing menus and simulating restaurants.
3. Enhance the awareness of being responsible for your health and develop good eating habits.
Teaching emphases and difficulties
1, know the food pyramid and learn how to mix food scientifically and reasonably.
2. Design your own recipes according to the pyramid structure.

Teaching reflection
In this class, I mainly ask students to make tables with food. On the basis of making tables, students can initially understand the principles of food nutrition collocation, and know whether their diet is reasonable on the basis of exchange and discussion. In the second half, each team designed its own nutrition cookbook competition, and eight teams designed exquisite small cookbook tabloids, which pushed the activity to a climax. Let students have a more systematic understanding of how to match food through the display, exchange and mutual evaluation of each team. Starting from life, create problem scenarios, guide students to "find and solve problems", and carry out interesting extracurricular practical activities for students to test in practice and apply in life. This can not only stimulate students' interest, but also apply textbook knowledge to life, which embodies the truth that "science comes from life and is applied to life". Finally, let students talk about their feelings and arrange an extracurricular interest activity to extend students' interest in learning to extracurricular activities. Through study and investigation, although many students know that their diet should be reasonably matched, due to their personal preferences, they often have partial eclipse and picky eaters in their lives, which also reflects that classroom education alone can not achieve the teaching purpose and needs the cooperation of family education.
