With time travel and mysteries that need solving, the Galactic Academy of Science (G.A.S.) series instructs readers on how to think like scientists. Under the guidance of a Dude or Dudette from the future, the middle school characters are faced with treacherous, present-day crimes that require a historical knowledge of science in order to be solved. From investigating problems to analyzing data and constructing explanations and solutions, this series blends elements of sci-fi with educational methods that distill the key thinking habits of scientists and engineers. An adventure that investigates the causes and consequences of climate change Something strange is going on during Anita and Benson’s field trip to a greenhouse as their guide is making wild claims about carbon dioxide and their science teacher, Mr. Fazmel, has mysteriously disappeared. That’s when Quarkum Phonon, a Dude from the future, sends Anita and Benson on a Galactic Academy of Science mission to learn about the origins of climate change and the ways communities around the world are dealing with its impact. With stops around the world—from a Hawaiian volcano to Greenland and Geneva—Anita and Benson sift through the evidence for climate change. On their return home, the students face the question: what can a couple of kids do to reduce CO2 emissions and slow down climate change? A portion of all profits from this book will go to support local projects helping people in the developing world adapt to climate change.
