Starting from the building block color laboratory, in terms of mathematics, we will reconstruct the understanding of cubes. In terms of chemistry, we will conduct color experiments with oil and water. In terms of art, we will sample color designs from life, learn about wood materials and coloring materials, and create our own Textured color building blocks set. Allow students to explore diverse materials in the course of playing, experimenting, and thinking, hoping to create connections corresponding to the different areas of interest of each student.
