Explore possible issues of environmental color, enter into discussions of color science, and explain color phenomena from an optical perspective (cross-field: physics). I hope to explore and collect the colors of the campus by observing the campus environment. Before using color chips to explore environmental colors, review basic color science concepts to understand the system and arrangement logic of the color chips. Use the color chips to collect the real environmental colors of your favorite places on Yongren campus, and then ask students to use their spare time , use the mobile app to capture the color combinations at three time points here, compare the real color with the light and humanistic conditions at different time points, and make detailed records of how the colors change. Select a color as the student's favorite Yongren color, describe the time when this color appeared, and the reason for liking it. Use this color to practice color matching and understand the principles and methods of color matching. Students will match the main environmental color with the auxiliary color of their choice to achieve the target Object - "Wind Chime" for color planning. During the process, the texture of the area was also examined, and the mold was made with clay and plaster, and the result was presented on the wind chime in a small area. The wind chime uses a lot of woodworking techniques (cross-field: life science and technology) to help complete the wind chime. Half of the students who chose the copper pipe part of the wind chime chose to make it from tree branches on campus, so that all the wind chime production elements came from the campus, which is closer to what this course wants to achieve. Various sensory and expressive media connect back to the purpose of campus memory. Finally, the Chinese teacher was invited to guide the students to write a short poem (cross-disciplinary: Chinese) to express their emotions about this place through the medium of wind chimes. By making wind chimes. Students can learn to design ways to solve life problems through the process of brainstorming and hands-on attempts. Echoing the core competencies of the 12-year national education, "Have the ability to plan and execute plans, explore and develop diverse professional knowledge, enrich life experience, and exert an innovative spirit to respond to social changes and enhance personal flexibility and adaptability."
