These demonstrations will fascinate, amaze, and teach students the wonders and practical science of physics. Physics Demonstrations illustrates properties of motion, heat, sound, electricity, magnetism, and light. All demonstrations include a brief description, a materials list, preparation procedures, a provocative discussion of the phenomena displayed and the principles illustrated, important information about potential hazards, and references. Suitable for performance outside the laboratory, Physics Demonstrations is an indispensable teaching tool. This book includes a DVD of the author performing all 85 demonstrations.
PRESENTS A COLLECTION OF PHYSICS DEMONSTRATIONS THAT ILLUSTRATE KEY CONCEPTS USING EASILY ACCESSIBLE MATERIALS, WITH INFORMATION PROVIDING A THEORETICAL BACKGROUND FOR EACH DEMONSTRATION.

Interactive Lecture Demonstrations (ILDs) are designed to enhance conceptual learning in physics lectures through active engagement of students in the learning process. Students observe real physics demonstrations, make predictions about the outcomes on a prediction sheet, and collaborate with fellow students by discussing their predictions in small groups. Students then examine the results of the live demonstration (often displayed as real-time graphs using computer data acquisition tools), compare these results with their predictions, and attempt to explain the observed phenomena. ILDs are available for all of the major topics in the introductory physics course and can be used within the traditional structure of an introductory physics course. All of the printed materials needed to implement them are included in this book.
A laboratory manual for high schools, colleges, and universities, this book contains more than 80 experiments and lecture demonstrations. The coverage includes the essentials of general physics: mechanics and molecular physics, electricity and magnetism, optics and atomic physics, and condensed matter physics. All the experiments are illustrated through the results of real measurements and include many novel experiments developed by the author.
In the long-awaited sequel to TURNING THE WORLD INSIDE OUT AND 175 OTHER SIMPLE PHYSICS DEMONSTRATIONS, Robert Ehrlich provides a new collection of more than 100 physics demonstrations and experiments which continue to prove that physics can be "made simple". The professional, the professor, the student, or even the lay person with even the slightest interest in physics will find Ehrlich's book fascinating. Illus.
". . . dipping into this collection is much like opening a holiday gift and discovering a marvelous little toy that then holds your attention by some curious performance. . . . This book precisely reflects the way science education should be, especially at the introductory level." --From the foreword Here is a collection of physics demonstrations costing very little to produce yet illustrating key concepts in amazingly simple and playful ways. Intended for instructors, students, and curious lay readers, these demonstrations make use of easily accessible, everyday items: food coloring and glycerine swirled and then "unmixed" in a container demonstrate aspects of the entropy law; raw eggs thrown with full force at a sheet but not breaking illustrate Newton's second law (f=ma); and the reflection off a glass Christmas tree ball is the focus of an explanation on "turning the world inside out." Many of the demonstrations are either new or include innovative twists on old ideas, as in the author's simplified version of the classic "Monkey and Hunter" problem, which substitutes "diluted gravity" on an inclined plane for large apparatus. Each demonstration outlines the objective, the equipment needed, and the procedure, including, in many instances, ways for a teacher to perform the demonstration on an overhead projector. Throughout the book concrete examples are accompanied by enough theoretical background to enhance a reader's basic understanding of physical principles. Lab instructors will find that demonstrations containing a quantitative component work well as mini- experiments and as ways to illustrate the results of calculations. These diverse and flexible demonstrations will serve a wide range of educational levels, from middle school physical science to university physics.
This book on the use of Arduino and Smartphones in physics experiments, with a focus on mechanics, introduces various techniques by way of examples. The main aim is to teach students how to take meaningful measurements and how to interpret them. Each topic is introduced by an experiment. Those at the beginning of the book are rather simple to build and analyze. As the lessons proceed, the experiments become more refined and new techniques are introduced. Rather than providing recipes to be adopted while taking measurements, the need for new concepts is raised by observing the results of an experiment. A formal justification is given only after a concept has been introduced experimentally. The discussion extends beyond the taking of measurements to their meaning in terms of physics, the importance of what is learned from the laws that are derived, and their limits. Stress is placed on the importance of careful design of experiments as to reduce systematic errors and on good practices to avoid common mistakes. Data are always analyzed using computer software. C-like structures are introduced in teaching how to program Arduino, while data collection and analysis is done using Python. Several methods of graphical representation of data are used.
