Abstract

In the chapter “Light and Color” of the science book for seven-grade student, which is published by Zhejiang education publisher, we can produce the phenomenon of light dispersion by irradiating the prism with sunlight. The color of the colored light band is red, orange, yellow, green, blue, indigo, and purplearranged in order, and experiments have shown that white light is made of a mixture of multiple color lights. In the textbook, there is no experimental demonstration to demonstrate that red, green, and blue colors can be mixed. Based on this, I have made my own RGB light-emitting diode three-primary-color synthesis experimental teaching aids, and used the intuitive three-primary-color synthesis demonstration experiment in the classroom to explore the various colors of red, green, and blue. Students are interested in learning science. At the same time, students' hands-on ability and scientific inquiry ability are cultivated.
