Excerpt from A Text-Book on the Elements of Physics for High Schools and Academies
Every teacher has a method of his own. But perhaps the follow ing plan, practised by the author, may be suggestive to some: He divides the experiments into three classes: home, laboratory, and lecture-room experiments. The first class are indicated in the assign ment of a lesson. They are such as may be performed with such simple means as every pupil has at his home. The laboratory experi ments are conducted as follows: Suppose that the number of pupils engaged at one time is fifteen, about as many as one teacher can care for successfully, and that the number of experiments to be performed during the hour is five, which is about an average number; then, to save a multiplicity of apparatus of the same kind, only three sets of apparatus of a kind are provided for each experiment. As soon as a pupil completes an experiment with one piece of apparatus, he looks about for an idle piece of some other kind; or, finding none, he improves the time in writing notes on his experiments until apparatus is ready for him; in this way each pupil performs five experiments during the hour, and devotes an average time of twelve minutes to each experiment, including the time of writing notes. The third class of experiments include such as require the use of apparatus that cannot safely be placed in the hands of pupils, - a very limited number, and those which have been performed by the pupils, and which the teacher may wish to repeat in a more elaborate way.

Paperback. Condition: New. Print on Demand. This book takes readers on a journey into the fascinating world of physics, exploring the fundamental nature of matter and the forces that govern its behavior. Drawing on a rich history of scientific inquiry, the book delves into the principles of attraction, repulsion, and the three states of matter: solid, liquid, and gas. The author invites readers to explore the invisible world of molecules, demonstrating how these tiny particles, though imperceptible to the naked eye, are responsible for the properties of every object we see and touch. The book also explores the concept of force, from the everyday experience of gravity to the more subtle forces that operate at the molecular level. Through a series of engaging experiments, the book encourages readers to understand the principles of physics in a hands -on way, fostering a deeper appreciation for the natural world and the scientific method. The book's insights, rooted in the scientific understanding of the 19th century, provide a compelling foundation for comprehending the laws of nature that continue to shape our world today.
