Each investigation in this book asks a question and presents a plan of action. None has a single 'right answer, ' yet all can be answered in some way. There's no answer key--it's up to students to use their critical thinking skills and number sense to evaluate their work and the work of their classmates. It's up to you to help them recognize and apply the math ideas embedded in every investigation, such as patterns and relationships, computation, estimation, measurement, statistics, and proportional reasoning.- from the book.Grades 5-8.
Night 1 / My life is perfect. / I have a bowl full of seeds, a cozy pile of wood shavings, and room to run. / I'm never leaving here. / Question: Who's the luckiest hamster in the world? / Answer: ME! Seymour the hamster has the perfect life. He has a spacious cage, a constant food supply, and a FuzzyBoy 360 exercise wheel that lets him run to his heart's content. Life could not be better. Or could it? When Pearl the cat tells Seymour of the goodies beyond the safe confines of his cage, he starts to think he's missing out. And out is the new in! It's only after Seymour is out of his cage that he begins to fully appreciate his safe and cozy home.
"It may be that I have stumbled upon an adequate description of life itself." These modest yet profound words trumpet an imminent paradigm shift in scientific, economic, and technological thinking. In the tradition of Schrödinger's classic What Is Life?, Kauffman's Investigations is a tour-de-force exploration of the very essence of life itself, with conclusions that radically undermine the scientific approaches on which modern science rests--the approaches of Newton, Boltzman, Bohr, and Einstein. Building on his pivotal ideas about order and evolution in complex life systems, Kauffman finds that classical science does not take into account that physical systems--such as people in a biosphere--effect their dynamic environments in addition to being affected by them. These systems act on their own behalf as autonomous agents, but what defines them as such? In other words, what is life? Kauffman supplies a novel answer that goes beyond traditional scientific thinking by defining and explaining autonomous agents and work in the contexts of thermodynamics and of information theory. Much of Investigations unpacks the progressively surprising implications of his definition. Significantly, he sets the stages for a technological revolution in the coming decades. Scientists and engineers may soon seek to create autonomous agents--both organic and mechanical--that can not only construct things and work, but also reproduce themselves! Kauffman also lays out a foundation for a new concept of organization, and explores the requirements for the emergence of a general biology that will transcend terrestrial biology to seek laws governing biospheres anywhere in the cosmos. Moreover, he presents four candidate laws to explain how autonomous agents co-create their biosphere and the startling idea of a "co-creating" cosmos. A showcase of Kauffman's most fundamental and significant ideas, Investigations presents a new way of thinking about the fundamentals of general biology that will change the way we understand life itself--on this planet and anywhere else in the cosmos.
