chemical vs physical properties worksheet: Friendly Chemistry Student Edition Joey Hajda, 2011-01-07 Friendly Chemistry is a truly unique approach to teaching introductory chemistry. Used by home schoolers and charter, public and private school students world-wide for over ten years, Friendly Chemistry presents what is often considered an intimidating subject as a genuinely fun, enjoyable experience. Whether you're a high-school aged student needing a lab science course or a non-traditional student looking for a refresher course to help you prepare for an upcoming entrance exam, Friendly Chemistry can help you accomplish your goal in a painless way! If you do have aspirations of a future in a science field, Friendly Chemistry can give you the solid foundation you need to succeed in subsequent courses.Friendly Chemistry was written using simple language and a host of analogies to make learning (and teaching!) chemistry easy. The chemistry concepts presented in Friendly Chemistry are NOT watered-down. The concepts are just explained in ways that are readily understood by most learners. Coupled with these explanations is a host of teaching aids, labs and games which makes the learning concrete and multi-sensory. Students find the course fun and painless. Parents often comment, I wish I had had this when I was taking chemistry. Now it all makes so much sense! Friendly Chemistry covers the same topics taught in traditional high school chemistry courses. The course begins with an introduction to atomic theory followed by discussion of why the elements are arranged the way they are in the periodic table. Quantum mechanics comes next using the acclaimed Doo-wop Board as a teaching aid. Next comes a discussion of how atoms become charged (ionization), followed by an explanation of how charged atoms make compounds. The mole is introduced next, followed by a discussion of chemical reactions. Stoichiometry (predicting amounts of product produced from a reaction) is treated next followed by a discussion of solutions (molarity). The course is wrapped up with a discussion of the ideal gas laws. Please note that this is the STUDENT EDITION. Volumes 1 and 2 of the TEACHERS EDITION must be purchased separately in order to have all materials necessary to complete this chemistry course.

chemical vs physical properties worksheet: 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, 2012-02-28 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. |

chemical vs physical properties worksheet: Microscale Chemistry John Skinner, 1997 Developing microscale chemistry experiments, using small quantities of chemicals and simple equipment, has been a recent initiative in the UK. Microscale chemistry experiments have several advantages over conventional experiments: They use small quantities of chemicals and simple equipment which reduces costs; The disposal of chemicals is easier due to the small quantities; Safety hazards are often reduced and many experiments can be done quickly; Using plastic apparatus means glassware breakages are minimised; Practical work is possible outside a laboratory. Microscale Chemistry is a book of such experiments designed for use in schools and colleges, and the ideas behind the experiments in it come from many sources, including chemistry teachers from all around the world. Current trends indicate that with the likelihood of further environmental legislation, the need for microscale chemistry teaching techniques and experiments is likely to grow. This book should serve as a guide in this process. |
