Bøger af William C. Robertson

Never has it been so easy for educators to learn to teach physical science with confidence. Award-winning author Bill Robertson launched his bestselling Stop Faking It! Series in 2002, with Force and Motion. This proves an ideal supplement to the original book - or a valuable resource of its own. The hands-on activities and highly readable explanations allow students to first investigate concepts, then discuss learned concepts, and finally apply the concepts to everyday situations.

Muddled about what makes music? Stuck on the study of harmonics? Dumbfounded by how sound gets around? Now you no longer have to struggle to teach concepts you really don't grasp yourself. Sound takes an intentionally light touch to help out all those adults-- science teachers, parents wanting to help with homework, home-schoolers-- seeking necessary scientific background to teach middle school physics with confidence. The book introduces sound waves and uses that model to explain sound-related occurrences. Starting with the basics of what causes sound and how it travels, you'll learn how musical instruments work, how sound waves add and subtract, how the human ear works, and even why you can sound like a Munchkin when you inhale helium. Sound is the fourth book in the award-winning Stop Faking It! Series, published by NSTA Press. Like the other popular volumes, it is written by irreverent educator Bill Robertson, who offers this Sound recommendation: " One of the coolest activities is whacking a spinning metal rod to create a ' wah-wah' effect. It's a simple activity, the explanation incorporates several interesting properties of sound. This activity is in Chapter 5. I suggest you try it and see!"

With Bill Robertson as your guide, you will discover you can come to grips with the basics of force and motion. This book will lead you through Newton's laws to the physics of space travel. The book is as entertaining as it is informative. Best of all, the author understands the needs of adults who want concrete examples, hands-on activities, clear language, diagrams and yes, a certain amount of empathy.
