Description: A thrilling experiment-battle comic that makes difficult scientific principles and terms easy for children to understand through exciting stories of elementary school students conducting experiments. This series was designed to give children the chance to see science not as something to fear, but as something fun and enjoyable through entertaining experiments. Through the main characters' activities in their experiment club, readers can naturally encounter the experiments and related scientific theories found in upper elementary school textbooks. The characters' engaging rivalries and suspenseful competitions help draw readers into the story while making scientific knowledge more approachable. The series also covers scientific principles behind everyday life that even adults often don't know, providing useful information for daily living. Following Book 1, 'Battle of Acids and Bases,' Book 2, 'Battle of Forces,' delivers a wide range of learning content related to 'force' — including Newton's three laws of motion, gravity, elasticity, and friction — through the thrilling first experiment competition of the lively Saebyeok Elementary Experiment Club. To help readers directly experience and easily understand the first competition topic, 'The Law of Action and Reaction,' an experiment kit is included. Inside the kit are the parts for an air rocket — the same kind used in real elementary school experiment and science club competitions — along with a guide to help make the experiment fun. This experiment kit replaces expensive launch equipment with an easily obtainable plastic bottle as the launcher, allowing kids to enjoy handling an air rocket while learning about the principle of action and reaction.
