The materials used for the experiment were developed at the school, and science teaching materials were developed that can be understood by primary and junior high school students. As a photochromic material, "Ninja Enogu" used for detecting ultraviolet rays contained in sunlight is used to attract children's interest in color through how to mix paints and how to paint colors, and to use the color of matter I did research that led to the explanation of scientific principles. In addition, a leuco dye-based thermochromic ink was developed that mimics the thermochromic reaction of the ink used in a commercially available friction pen, using a chemical available at the school.
