Wow! How? Few techniques are as effective at generating interest in science as dramatic demonstrations. This fully illustrated sourcebook describes eighty-five physics demonstrations suitable for performance both inside and outside classrooms. These demonstrations will fascinate and amaze while teaching the wonders and practical science of physics. Videos for the demonstrations are online at http://physicsdemonstrationsvideos.com/. Dr. Sprott shares demonstrations tested over many years in his popular public lectures on “The Wonders of Physics,” which appeal to general audiences and to students from grade school to graduate school. Science teachers at all levels will find a wealth of detail showing how to present these demonstrations to students with flair. Science professionals will find indispensable information for creating educational and entertaining public programs. Organized to teach the six major areas of classical physics—motion, heat, sound, electricity, magnetism, and light—Physics Demonstrations includes: a brief description of each demonstration materials lists, with sources for common materials preparation procedures discussions of the physics principles demonstrated potential safety hazards references for further information.
