Description: A full-fledged competitive science invention comic series newly created by the writing team behind 'Tomorrow's Science King.' Through everyday inventions, readers learn scientific principles while building creative thinking skills. Centered on the charismatic members of the Gosu Elementary Invention Club (who first appeared in Volume 2 of 'Tomorrow's Science King'), the series vividly portrays their hands-on journey of turning witty ideas into reality through thrilling invention competitions. In Volume 11, 'Applying Ideas,' readers naturally encounter scientific theory through the process of creating various inventions, including a 'Water-Propelled Car' made from a plastic bottle and a 'No-Tissue Alert Sensor' using a magnetic sensor. The volume also carefully covers essential concepts from the elementary science curriculum, including light and shadow play (Grades 3-4, 'Mirrors and Shadows' unit), sensory organs (Grade 5, Semester 2, 'Our Body' unit), light refraction, how we see objects, and lens properties (Grade 6, Semester 1, 'Light' unit), and types of energy and energy conversion (Grade 6, Semester 2, 'Energy and Tools' unit), enhancing the book's educational value through a well-structured design.
