Based on the theme of flowering plants in the field of natural sciences, and guided by Taiwan's endemic plants, we enter the theme of "Flower Structure", allowing students to understand Taiwan's endemic plants and understand the characteristics and functions of flowering plants' "flowers" , and then appreciate the different shapes and postures of flowers and plants, and use various colors of paper to use their own ideas and creativity to make three-dimensional paper flowers, plus leaves of various shapes made from paper, and combine them into pots of flower arrangements. Works and results displayed in campus activities.
