Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an "idealist" inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion.
This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.
This book is for chemistry teachers who are thinking about reinventing how they design their labs. More than a collection of experiments, it is an example of using a chemical theme to teach chemistry.
This teacher resource contains experiments involving a small set of safe substances that are appropriate for high school and college chemistry students. Instead of introducing many different chemicals per experiment as is the norm in most commercial lab manuals, this resource focuses on two commonly found elements: Zinc and Iodine.
So what is so special about these elements? At the heart of this resource is a colorful cyclic reaction between zinc and iodine, one that produces a compound that can decompose back to its original elements. This unique phenomenon demonstrates that matter not only changes, but, is also conserved through a chemical reaction. Knowing that a compound can be the “same but different” than the reactants that formed it, is to understand the essence of chemical change.
This resource also draws upon zinc and iodine’s versatile chemical properties. The ability to undergo different types of reactions with other substances allows students to learn a breadth of chemical concepts and quantitative principles. Complementing the experiments leading up to and including chemical change, this book contains activities involving solution and gas stoichiometry, equilibrium, kinetics, acid-base chemistry, and electrochemistry.
While unconventional, the advantages of thematic laboratory teaching in chemistry are promising. Revisiting the same family of substances from one lab experience to another could help students decrease the cognitive complexity of their learning as well as help to scaffold and integrate their knowledge in more meaningful ways. Furthermore, students have the opportunity to act like real research chemists who develop expertise by building up a knowledge base around a particular set of substances.

Science Matters is a rare exception-a science book for the general reader that is informative enough to be a popular textbook for introductory courses in high school and college, and yet well-written enough to appeal to general readers uncomfortable with scientific jargon and complicated mathematics. And now, revised and expanded for the first time in nearly two decades, it is up-to-date, so that readers can enjoy Hazen and Trefil's refreshingly accessible explanations of the most recent developments in science, from particle physics to biotechnology.
Teaching science to English Language Learners combines research findings with classroom vignettes and the perspectives of teachers. The chapter authors strive to support your efforts to see diversity as a resource, rather than as an obstacle, in the science classroom. Among their topics: building on what students know and recognizing students' strengths; teaching vocabulary for learning; supporting the development of academic language; challenges associated with learning a second language; types of programs for teaching English language learners; and using students' cultural resources.
Mastering the principles outlined in the book will give any teacher a braod base of knowledge from which to draw. But the book also urges you to think deeply about the roles of diversity. It offers valuable information for reflecting on, experimenting with, and adapting your instructional practices. As the authors note, "the vision of science teaching and learning put forward in this volume is one in which English lanaguage learners have as much to teach their fellow students as they have to learn from them."
As outlined in previous volumes, teachers, like their students, can have misconceptions that come to the fore when administering the probes. Volume 3 provides 10 detailed suggestions for teachers on how to use the probes to uncover, accurately assess, and correct their own preconceptions as well as their students' (e.g., do the probes yourself, examine student responses with other teachers, embed the probes into existing professional development programs, select specific areas to focus on, examine student thinking across grade spans, categorize ideas, and crunch data to create classroom profiles).
Volume 3 offers five life science probes, seven Earth and space science probes, ten physical science probes, and three nature of science probes. This volume is an invaluable resource for classroom teachers, preservice teachers, professional developers, and college science and preservice faculty.
The probes are invaluable formative assesment tools to use before you begin teaching a topic or unit. The detailed teacher materials that accompany each probe review science content, give connections to National Science Education Standards and Benchmarks; present developmental considerations; summarize relevant research on learning; and suggest instructional approaches for elementary, middle, and high school students. Other books may discuss students' general misconceptions about scientific thinking about scientific ideas. Only this one provides probes, single, reproducible sheets, you can use to determine students' thinking about, for example, photosynthesis, moon phases, conservation of matter, reflections, chemical change, and cells. Each probe has been field-tested with hundreds of students across multiple grade levels, so they're proven effective for helping your students reexamine and further develop their understanding of science concepts.
