| meiosis grade 12: Science Curriculum Topic Study Page Keeley, Joyce Tugel, 2019-09-11 Today’s science standards reflect a new vision of teaching and learning. | How to make this vision happen Scientific literacy for all students requires a deep understanding of the three dimensions of science education: disciplinary content, scientific and engineering practices, and crosscutting concepts. If you actively engage students in using and applying these three dimensions within curricular topics, they will develop a scientifically-based and coherent view of the natural and designed world. The latest edition of this best-seller, newly mapped to the Framework for K-12 Science Education and the Next Generation Science Standards (NGSS), and updated with new standards and research-based resources, will help science educators make the shifts needed to reflect current practices in curriculum, instruction, and assessment. The methodical study process described in this book will help readers intertwine content, practices, and crosscutting concepts. The book includes: • An increased emphasis on STEM, including topics in science, technology, and engineering • 103 separate curriculum topic study guides, arranged in six categories • Connections to content knowledge, curricular and instructional implications, concepts and specific ideas, research on student learning, K-12 articulation, and assessment Teachers and those who support teachers will appreciate how Curriculum Topic Study helps them reliably analyze and interpret their standards and translate them into classroom practice, thus ensuring that students achieve a deeper understanding of the natural and designed world. |
| meiosis grade 12: A Framework for K-12 Science Education National Research Council, Division of Behavioral and Social Sciences and Education, Board on Science Education, Committee on a Conceptual Framework for New K-12 Science Education Standards, 2012-03-28 Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments. |
| meiosis grade 12: The Plant Cell Cycle Dirk Inzé, 2011-06-27 In recent years, the study of the plant cell cycle has become of major interest, not only to scientists working on cell division sensu strictu , but also to scientists dealing with plant hormones, development and environmental effects on growth. The book The Plant Cell Cycle is a very timely contribution to this exploding field. Outstanding contributors reviewed, not only knowledge on the most important classes of cell cycle regulators, but also summarized the various processes in which cell cycle control plays a pivotal role. The central role of the cell cycle makes this book an absolute must for plant molecular biologists. |

It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. |

| meiosis grade 12: The Gene Siddhartha Mukherjee, 2016-05-17 The #1 NEW YORK TIMES Bestseller The basis for the PBS Ken Burns Documentary The Gene: An Intimate History Now includes an excerpt from Siddhartha Mukherjee’s new book Song of the Cell! From the Pulitzer Prize–winning author of The Emperor of All Maladies—a fascinating history of the gene and “a magisterial account of how human minds have laboriously, ingeniously picked apart what makes us tick” (Elle). “Sid Mukherjee has the uncanny ability to bring together science, history, and the future in a way that is understandable and riveting, guiding us through both time and the mystery of life itself.” —Ken Burns “Dr. Siddhartha Mukherjee dazzled readers with his Pulitzer Prize-winning The Emperor of All Maladies in 2010. That achievement was evidently just a warm-up for his virtuoso performance in The Gene: An Intimate History, in which he braids science, history, and memoir into an epic with all the range and biblical thunder of Paradise Lost” (The New York Times). In this biography Mukherjee brings to life the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices. “Mukherjee expresses abstract intellectual ideas through emotional stories…[and] swaddles his medical rigor with rhapsodic tenderness, surprising vulnerability, and occasional flashes of pure poetry” (The Washington Post). Throughout, the story of Mukherjee’s own family—with its tragic and bewildering history of mental illness—reminds us of the questions that hang over our ability to translate the science of genetics from the laboratory to the real world. In riveting and dramatic prose, he describes the centuries of research and experimentation—from Aristotle and Pythagoras to Mendel and Darwin, from Boveri and Morgan to Crick, Watson and Franklin, all the way through the revolutionary twenty-first century innovators who mapped the human genome. “A fascinating and often sobering history of how humans came to understand the roles of genes in making us who we are—and what our manipulation of those genes might mean for our future” (Milwaukee Journal-Sentinel), The Gene is the revelatory and magisterial history of a scientific idea coming to life, the most crucial science of our time, intimately explained by a master. “The Gene is a book we all should read” (USA TODAY). |

| meiosis grade 12: Molecular Biology Nancy Craig, Rachel Green, Orna Cohen-Fix, Carol Greider, Gisela Storz, Cynthia Wolberger, 2014-05 The biological world operates on a multitude of scales - from molecules to tissues to organisms to ecosystems. Throughout these myriad levels runs a common thread: the communication and onward passage of information, from cell to cell, from organism to organism and ultimately, from generation to generation. But how does this information come alive to govern the processes that constitute life? The answer lies in the molecular components that cooperate through a series of carefully-regulated processes to bring the information in our genome to life. These components and processes lie at the heart of one of the most fascinating subjects to engage the minds of scientists today: molecular biology. Molecular Biology: Principles of Genome Function, Second Edition, offers a fresh approach to the teaching of molecular biology by focusing on the commonalities that exist between the three kingdoms of life, and discussing the differences between the three kingdoms to offer instructive insights into molecular processes and components. This gives students an accurate depiction of our current understanding of the conserved nature of molecular biology, and the differences that underpin biological diversity. Additionally, an integrated approach demonstrates how certain molecular phenomena have diverse impacts on genome function by presenting them as themes that recur throughout the book, rather than as artificially separated topics As an experimental science, molecular biology requires an appreciation for the approaches taken to yield the information from which concepts and principles are deduced. Experimental Approach panels throughout the text describe research that has been particularly valuable in elucidating difference aspects of molecular biology. Each panel is carefully cross-referenced to the discussion of key molecular biology tools and techniques, which are presented in a dedicated chapter at the end of the book. Molecular Biology further enriches the learning experience with full-color artwork, end-of-chapter questions and summaries, suggested further readings grouped by topic, and an extensive glossary of key terms. Features: A focus on the underlying principles of molecular biology equips students with a robust conceptual framework on which to build their knowledge An emphasis on their commonalities reflects the processes and components that exist between bacteria, archae, and eukaryotes Experimental Approach panels demonstrate the importance of experimental evidence by describing research that has been particularly valuable in the field |
| meiosis grade 12: Evolution and Speciation in Fungi and Eukaryotic Biodiversity T. J. Pandian, 2023-10-20 Being sessiles like autotrophic plants and heterotrophics as animals, fungi are fascinating eukaryotes. In them, the need for external digestion has demanded surface expansion and limited tissues to 20% loss of commercial crops. Despite their ecological and economic importance, no university offers a degree course in Mycology. For 2,056,907 eukaryotic species, this book elaborates the role played by environmental factors (i) spatial distribution, (ii) light-temperature, (iii) precipitation-liquid water and biological attributes, (iv) cellularity, (v) symmetry, (vi) clonality, (vii) sexuality, (viii) modality and (ix) motility that either accelerate or decelerate biodiversity. About 20 and 80% eukaryotes are aquatics and terrestrials. Decreasing light intensity and temperature reduce diversity from the equator toward the polar zones. Water availability also reduces the diversity from 5.4 - 65.5 species/km2 in tropical evergreen forests to 200 in mammals reduces clonality from 100 to 0%. Strategies developed by eukaryotes reduce selfing by |
| meiosis grade 12: Crossing Over Edith Dempster, 2006 This workbook was developed to support Crossing Over, a pilot research programme for training teachers in contemporary science education (a project of the Human Sciences Research Council and the Africa Genome Initiative). The project aimed to equip educators with the necessary skills and knowledge to deal with changes in the Natural Sciences and Life Sciences curricula. The workbook provides key content necessary for teaching concepts recently introduced in these curricula: comparative functioning, relationships and the development of change, or evolution. This is an interactive, well-illustrated workbook that helps teachers to build their own understanding of genes, the mechanisms of inheritance and selection - the basic principles of evolution. It is divided into two parts, with the first intended to supplement the work of General Education and Training (GET) teachers, and the second providing support for Further Education and Training (FET) teachers. |
| meiosis grade 12: The Triumph of the Fungi Nicholas P. Money, 2006-08-31 This book is concerned with the most devastating fungal diseases in history. These are the plagues of trees and crop plants, caused by invisible spores that have reshaped entire landscapes and decimated human populations. The Triumph of the Fungi focuses on the fascinating biology of the well- and lesser-known diseases, and also tells the stories of the scientists involved in their study, and of the people directly impacted by the loss of forest trees like the chestnut, and cash crops such as coffee and cacao. In a surprisingly brief time, human knowledge of the fungi that infect plants has evolved from Biblical superstition, to the recognition of the true nature of plant disease, and, more recently, to a sense of awe for the sophistication of these microbes. The crucial issue of human culpability in these fungal epidemics is addressed in the books closing chapter. |
| meiosis grade 12: Engaging with Contemporary Challenges through Science Education Research Olivia Levrini, Giulia Tasquier, Tamer G. Amin, Laura Branchetti, Mariana Levin, 2021-09-24 This book starts with the premise that beauty can be an engine of transformation and authentic engagement in an increasingly complex world. It presents an organized picture of highlights from the 13th European Science Education Research Association Conference, ESERA 2019, held in Bologna, Italy. The collection includes contributions that discuss contemporary issues such as climate change, multiculturalism, and the flourishing of new interdisciplinary areas of investigation, including the application of cognitive neuroscience, artificial intelligence, and digital humanities to science education research. It also highlights learners’ difficulties engaging with socio-scientific issues in a digital and post-truth era. The volume demonstrates that deepening our understanding is the preferred way to address these challenges and that science education has a key role to play in this effort. In particular, the book advances the argument that the deep and novel character of these challenges requires a collective search for new narratives and languages, an expanding knowledge base and new theoretical perspectives and methods of research. The book provides a contemporary picture of science education research and looks to the theoretical and practical societal challenges of the future. |

| meiosis grade 12: The Unfit Elof Axel Carlson, 2001 Carlson's history of degeneracy theory, the idea that certain people are biologically disposed to become socially unfit or degenerate, examines the birth of both good and bad eugenics movements. While good eugenics movements focus on people whose needs may require intense social attention and expensive social investments, bad eugenics movements call for isolation if not eradication and genocide. He brings the history into the present day, where the potential misapplication of DNA science and social attitudes toward the human genome could lead to similar movements. |
| meiosis grade 12: Multiple Representations in Biological Education David F. Treagust, Chi-Yan Tsui, 2013-02-01 This new publication in the Models and Modeling in Science Education series synthesizes a wealth of international research on using multiple representations in biology education and aims for a coherent framework in using them to improve higher-order learning. Addressing a major gap in the literature, the volume proposes a theoretical model for advancing biology educators’ notions of how multiple external representations (MERs) such as analogies, metaphors and visualizations can best be harnessed for improving teaching and learning in biology at all pedagogical levels. The content tackles the conceptual and linguistic difficulties of learning biology at each level—macro, micro, sub-micro, and symbolic, illustrating how MERs can be used in teaching across these levels and in various combinations, as well as in differing contexts and topic areas. The strategies outlined will help students’ reasoning and problem-solving skills, enhance their ability to construct mental models and internal representations, and, ultimately, will assist in increasing public understanding of biology-related issues, a key goal in today’s world of pressing concerns over societal problems about food, environment, energy, and health. The book concludes by highlighting important aspects of research in biological education in the post-genomic, information age. |
