Why Do Scientists Disagree?

Why Do Scientists Disagree? is a book with two distinct but related threads. On the right-hand pages, students read about the ways scientists use evidence, make explanations, and debate their ideas to move the field forward. Science is defined as a community enterprise in which explanations are based on evidence and there is discussion about that evidence. On the left-hand pages, these ideas are exemplified in the story of the scientist Galileo and how his observations of the Moon changed people’s ideas about light. This book helps students to see that disagreement is an important and positive stage of scientific discussion that often leads to new understandings and eventual agreement.
