Description: Volume 11 of 'Tomorrow's Experiment King,' the educational comic series that makes tricky science concepts and terms easy and fun for elementary students through exciting hands-on experiment stories. This volume dives into the many scientific principles behind water — an essential part of our everyday lives — including the principle and discovery of buoyancy, surface tension, the definition of density, the structure and properties of water molecules, changes in solubility with temperature, and the water cycle. Covering topics from the 5th grade first semester unit 'Dissolving and Solutions' and the 6th grade second semester unit 'Weight and Pressure in Water,' the book explores experiments such as dissolving water and acetone, solubility and saturation of solutions, measuring the weight of modeling clay underwater, making soap bubbles, floating a needle on water, and the properties of water molecules that create surface tension — all the way up to middle school topics like the electrolysis of water and the water cycle. These core curriculum concepts are brought to life through thrilling experiment showdowns between the story's charismatic characters. Through intense and exciting experiment battles, the series' distinctive characters explain the scientific theories and terms found in upper elementary and middle school experiments in a way that's easy and enjoyable to understand. The book also aims to spark children's curiosity and interest in science by covering deeper scientific principles. Best of all, an included 'experiment kit' lets kids try the science featured in the book for themselves — turning simple memorization into hands-on learning with visible results.
