Description: Volume 9 of the 'Tomorrow's Science Wizard' series. This book introduces the science of weather—the sun and Earth, atmospheric circulation, rain and clouds, air pressure and wind—phenomena that change daily and affect our lives. Through the experiments, competitions, and training of the characters in the comic, kids can learn in a fun and memorable way. Information pages let readers experience hands-on activities such as making a hygrometer, visualizing air pressure differences, growing copper sulfate crystals, exploring Earth's radiative equilibrium, building a simple thermometer, and observing monsoon winds and convection. The book also comes with an experiment kit for building a wind vane, anemometer, and wind measuring stand, allowing kids to measure wind direction and speed themselves. By examining the pungigidae, a Joseon-era weather observation device, and learning to read the Beaufort wind scale used since the early 19th century, children can easily and enjoyably learn about weather instruments and principles as if playing a game.
