According to the requirements of teaching and children's experience, I think the focus of this activity is: let children know which leaves they can see in winter? Difficulties: Know the names of several leaves and the reasons why they don't fall.

Using children's interest in conversation activities, children can observe and discover the changes of leaves in nature, and through the display of courseware pictures, children can learn more about the changes of leaves in winter, thus effectively breaking through the difficulties of activities.

3. The purpose of the activity:

According to children's interest in exploration and teaching content, combined with children's age, I have set three goals suitable for children's development:

(1) Let children know that there are evergreen trees and deciduous trees.

(2) How many common evergreen trees are there?

(3) What leaves can you see in winter?

Second, the preparatory activities (physics textbooks)

1. knowledge preparation: please ask parents and children to collect information about evergreen trees together.

2. Information preparation:

(1) Let children go outdoors to observe the leaves of various trees.

(2) Let children think about which leaves will not fall in winter and collect them.

(3) Multimedia courseware "What Leaves Can I See in Winter"

Through these preparations, children's existing experience can be enriched, and children can explore problems actively and boldly, making it easier to break through important and difficult points.
