Science textbook for Queensland year 8 secondary students.
Science textbook for Queensland year 8 secondary students.
New QScience Essentials 7 has been specifically authored to meet the requirements of the Queensland Essential Learnings and Standards and the National Statements of Learning for Science. New QScience Essentials 7 is a full colour student workbook that will combine the Knowing and Understanding of Science with the Ways of Working. This book is all-in-one, so that students will be able to access their Science knowledge from the book as well as complete their exercises and practical work. This resource will fully prepare students for Science at Year 8. New QScience Essentials 7 is accompanied by a Teacher Resource Pack that contains photocopiable blackline masters that can be used for extra class work or homework. This pack also includes topic tests, links to Le@rning Federation Learning Objects, and answers to all workbook questions.
Contains up-to-date information presented in an age-appropriate context and visually stimulating format. The Wow! boxes present tidbits of scientific information that have been especially selected to capture students' interest.
The Student Workbooks are ancillaries to the New QScience Essentials 8 and 9 Student Books. They are designed to extend students beyond the scope of the material that appears in the Student Books by providing: * student focused activities * value added materials * material that consolidates student understanding and challenges their perceptions * additional problem solving and critical thinking activities. This material is in the form of: * literacy activities * communication tasks * comprehension exercises * secondhand data exercises * revision material * evaluation of experiments * investigation and inquiry activities. The Workbook material will further reinforce the Essential Learnings and assist in preparing students for state-wide assessment during Year 9.
Focusing on coenzyme Q, this book includes topics spanning from biochemical aspects to biomedical implications and clinical use of CoQ10. It addresses the antioxidant aspects as well as the non-mitochondrial electron transport systems, and investigates coenzyme Q biosynthesis in yeast and in Caenorhabditis elegans.
This book offers a comprehensive exploration of research on the essential relationship of the coenzyme Q10 and the process of aging in living organisms. CoQ10 is an important factor in two main aspects of cell physiology: bioenergetics and antioxidant protection. While primary deficiency of CoQ10 is associated with severe and lethal disease, secondary deficiency can be associated with the progression of mitochondrial dysfunction linked to the lessening of biological activities during aging. The book is organized in four sections. The first offers an overview of the function of CoQ10, highlighting the two main functions of CoQ10 in cells: its essential role as electron transport chain member in mitochondria, and the protection of cell membranes against oxidation as one of the main endogenous-synthesized antioxidants. The second section covers research on Coenzyme 10. Topics include studies involving invertebrate models, mammal studies and the influence of CoQ on longevity. Also covered is research involving the role of CoQ in senescence-accelerated mice. Section three examines the effects of reduced CoQ in human aging, as evident in mitochondrial dysfunction, metabolic syndrome, neurodegenerative disorders, immunosenescence and fertility and reproduction. The final section, Prolongevity effectors and Coenzyme Q, explores research into slowing or stopping the aging process. Coverage includes strategies including calorie restriction, and modulation of CoQ10 levels by induction of synthesis or by supplementation. Coenzyme Q in Aging benefits a broad readership of researchers, clinicians, educators and students interested in the biochemical and physiological effects of coenzyme Q and the importance of this molecule in aging process.
Science Essentials High School Level gives classroom teachers and science specialists a dynamic and progressive way to meet curriculum standards and competencies. Science Essentials are also available from Jossey-Bass publishers at the elementary school and middle school levels. You'll find the lessons and activities at each level actively engage students in learning about the natural and technological world in which we live by encouraging them to use their senses and intuitive abilities on the road to discovery. They were developed and tested by professional science teachers who sought to give students enjoyable learning experiences while preparing them for district and statewide proficiency exams. For easy use, the lesson and activities at the High School Level are printed on a big 81/2" x 11" lay-flat format that folds flat for photocopying of over 107 student activity sheets, and are organized into two sections: I. BIOLOGY (60 Lessons) Addresses the following topics: Fundamental Life Process, Single and Multicellular Organisms, Phenotypes, DNA/RNA, Genetics, Ecosystems, Internal Environments, Bacteria, and Viruses. II. CHEMISTRY (47 Lessons) Includes information about: Periodic Table of Elements, Properties of Matter, and Kinetic Molecular Theory. Each section offers detailed lessons with reproducible activity sheets for teaching basic concepts and skills in one main area of science at this level. Each lesson includes: The Basic Principle underlying the lesson and accompanying student activity The specific science Competency students will demonstrate A list of Materials needed to complete the activity An easy-to-follow, illustrated Procedure for presenting the lesson and accompanying student activity handout Observations & Analysis describing the desired results and answers to the student activity A two-page, illustrated Student Handout with step-by-step directions for carrying out the activity and recording observations and conclusions The lessons in each section are followed by sample test items focusing on the concepts and skills emphasized in that section. These will help students prepare for the types of questions they will be asked in actual test situations and are followed by answer keys. All three grade level volumes—elementary, middle school, and high school—give you stimulating and effective ways to help students master basic science content and prepare to demonstrate their knowledge at the particular level.
In recent years, remarkable discoveries have been made concerning the underlying mechanisms of aging. In Life-Span Extension: Single-Cell Organisms to Man, the editors bring together a range of illuminating perspectives from researchers investigating the aging process in a variety of species. This novel work addresses the aging process in species ranging from yeast to man and, among other subjects, features detailed discussions of the naked mole-rat, an exceptionally long-lived rodent; the relationship between dietary factors/food restriction and aging; and an evolutionary view of the human aging process. Single mutations that extend life span have been identified in yeast, worms, flies, and mice, whereas studies in humans have identified potentially important markers for successful aging. At the same time, it has been discovered that the genes and pathways identified in these studies involve a surprisingly small set of conserved functions, most of which have been the focus of aging research for some time. For example, the mTOR pathway, a regulator of translation and protein synthesis, has been identified as a common longevity pathway in yeast and Caenorhabditis elegans. In mammals, this pathway intersects with neuroendocrine pathways and with the insulin/insulin-like growth factor pathways, which have been identified as major modulators of life span and aging in both invertebrates and mice. Novel, emerging technologies and the increasingly wide variety of systems that are now used to study aging and the mechanisms of aging provide enormous opportunities for the identification of common pathways that modulate longevity. It is these common pathways that are the focus of this important volume.
