The series that explores science through adventure Acadia and two friends learn more science while enjoying a Maine winter. This is the third in a thoughtful series that began with Summer Science (2018). Like its predecessors, this combines a slight storyline with science facts, definitions, and descriptions of experiments using the scientific method. A melting snowman, a floating balloon, a paper-airplane contest, a wait outside in the cold, and a sledding challenge prompt 11-year-old Acadia's questions, which are presented in a present-tense narrative with unlikely dialogue but realistic daily details. Her parents are always happy to help her find answers, offering clear explanations, demonstrations, and encouragement for further experimentation. This outing introduces the topics of climate change, food waste, recycling and repurposing, atoms and elements, buoyancy, aerodynamics, animal adaptations for winter, and the physics of sledding.
