Description A full-fledged science invention comic series created by the writing team behind Tomorrow's Scientist King. Through everyday inventions, this series teaches scientific principles and nurtures creative thinking. In Book 3, readers naturally encounter scientific theories through the process of creating various inventions related to light, with detailed guidance to try making them firsthand. The book is closely aligned with the elementary science curriculum — including the principles of shadow formation from the 3rd Grade, 2nd Semester unit 'Light and Shadow,' the properties of light's straight-line travel, refraction, and reflection from the 6th Grade, 1st Semester unit 'Light,' as well as the dispersion of light from the middle school 2nd Grade unit 'Light and Waves' — helping to boost academic achievement through well-structured curriculum connections. The information pages summarize the key topics and important learning points covered in each volume at a glance. In the 'Explore at Home' corner, readers can try inventing a light bulb made from a mechanical pencil lead using electrical resistance, and a styrofoam cutter, while also learning about the invention process behind the light bulb — one of the world's top 100 inventions.

But it turns out their next opponent has already been decided?! Having won the 1st School Invention Competition by a narrow margin, Han Daebeom, On Yuhan, and Jang Jaeju finally achieve their wish of becoming an official invention club. This bruises the pride of Ice Princess Jo Yena, and Bang Gapsu isn't thrilled about their success either. Then Jo Yena crosses paths with the invention club from Narae Elementary, semifinalists in the last national competition! She arranges a practice match between Narae Elementary's club and Invention Class B, scheming to humble them. While Yuhan and Jaeju are left stunned by the sudden decision, a bold girl who once asked pointed questions at the school competition suddenly reappears... Will their next match go smoothly? Just like light that grows brighter when combined, please look forward to the continued adventures of Invention Class B, shining ever brighter with their curiosity for invention! Invention Kit: 'Sundial Using the Sun's Shadow + Simple Altitude Meter' Tomorrow's Inventor King includes a hands-on 'Invention Kit' so readers can directly experiment with and experience the key concepts covered in each book. Book 3 includes a kit for measuring time using the sun's shadow and discovering the sun's altitude with a simple altitude meter. Experience the wisdom of our ancestors, who once told time using sundials before clocks existed, and observe how the sun's altitude changes with the seasons — try it out yourself with the 'Sundial + Simple Altitude Meter'!
