Reflection and promotion

The children in the class can name several common vegetables, and some children know quite a lot. In the activity, I let the children observe the inside by touching the real vegetables and let the children smell the smell. Zixuan children said: onions stink, I don't like onions; Tomatoes have vitamins, and I like them. So I organized children to talk about their favorite vegetables and know what nutrients vegetables have, but they didn't know much about the nutrition and benefits of vegetables to our health. They just answered in general that vegetables contain vitamins, and the nutrients contained in vegetables are really difficult for children to master, not to mention children, and even our teachers are difficult to master. It is an abstract concept.
