Having survived disastrous dinosaurs in the first series installment, students at the Mad Scientist Academy now attempt to comprehend the mystery of weather. Six students make up the class assembled outside the laboratory: an amphibious creature, a werewolf, a robot, a vampire, a giant insect, and a monster resembling Frankenstein’s. Dr. Cosmic, whose flaming red hair recalls another cartoon scientist beloved by children, is ensconced in a wearable weather balloon, ready to test its efficacy. His colleague, meteorologist Nimbus, works the controls. As the sphere spins into the atmosphere, readers follow his progress and study charts to learn how clouds form and what causes wind, rain, and snow. Sequential panels move the plot forward and present information, while double-page spreads portray climactic moments, such as when the students try to apply what they have learned to correct the flood in the greenhouse and the snowstorm in the pool house by creating a tornado with the CHAOS machine. (The rear endpapers spell it out: Cooling/Heating Airflow Operating System.) Characters use their particular attributes to solve problems and help one another. Adults will appreciate the knowledge imparted in this STEM-friendly series as well as the encouragement to question, measure, and experiment; children will be attracted to the appealing caricatures and the cyclone wreaking havoc on the cover. With outlandish situations rendering scientific concepts memorable, McElligott has concocted a winning formula for learning as entertainment.
