Description: A science learning comic series that teaches scientific principles and terminology through experiments featured in upper elementary and middle school textbooks. Volume 6 covers foundational environmental topics such as air pollution, soil pollution, water pollution, acid rain, global warming, and natural purification. It also introduces basic science know-how like how to use a microscope, how to observe cells, and the differences between tap water and distilled water, along with the process of purifying tap water, testing water quality with reagents, and fun experiments using acid rain — all woven into the thrilling experiment competition of the Saebyeok Elementary Experiment Club. The included simplified water filter experiment kit recreates the natural water purification process in miniature. Inside the kit are charcoal, sand, gravel, gauze, rubber bands, a small liquid bottle, and a photo guide created by the editorial team based on their own hands-on testing. By trying this experiment firsthand, children can enjoyably learn how water is purified as it seeps into the ground.
