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.
Based on new evidence that challenges existing theories of urban inequality, Crankshaw argues that the changing pattern of earnings and occupational inequality in Johannesburg is better described by the professionalism of employment alongside high-levels of chronic unemployment. Central to this examination is that the social polarisation hypothesis, which is accepted by many, is simply wrong in the case of Johannesburg. Ultimately, Crankshaw posits that the post-Fordist, post-apartheid period is characterised by a completely new division of labour that has caused new forms of racial inequality. That racial inequality in the post-apartheid period is not the result of the persistence of apartheid-era causes, but is the result of new causes that have interacted with the historical effects of apartheid to produce new patterns of racial inequality.
