Description: An exciting experiment-showdown comic that uses fun science stories about elementary school students to explain difficult scientific principles and terms in an easy-to-understand way. It was created to give children the chance to see science as something fun and enjoyable, rather than something intimidating, through entertaining experiments. Through the experiment club activities of the main characters, readers can naturally encounter the experiment processes and related scientific theories found in upper-elementary textbooks. The exciting rivalries and tense showdowns between the characters also help draw readers into the story, making scientific knowledge easier to absorb. The series even covers scientific principles behind everyday life that many adults don't fully understand, providing useful real-world information. In Volume 3, 'Battle of Light,' the book covers core foundational concepts related to light—such as the straight-line travel, reflection, refraction, and composition of light, as well as convex lenses, concave lenses, and energy—helping readers easily and enjoyably absorb scientific knowledge about light, some of which is still not fully understood even by scientists today.
