In this organic chemistry laboratory experiment, students are guided through a series of exercises to understand the behavior of compounds during liquid-liquid extraction. Aspects of density, structure, solubility, acid-base theory, and pK[subscript a] are all incorporated into activities that students complete in groups. After using their initial…

Many students find the transition from first-year general chemistry to second-year organic chemistry a daunting task. There are many reasons for this, not the least of which is their lack of a solid understanding and appreciation of the importance of some basic concepts and principles from general chemistry that play an extremely critical role in…

This valuable and entertaining compendium of Bill Robertson's popular "Science 101" columns, from NSTA member journal "Science and Children," proves you don't have to be a science geek to understand basic scientific concepts. The author of the best-selling "Stop Faking It!" series explains everything from quarks to photosynthesis, telescopes to…

This textbook can be used in astronomy courses for schools and academies. Explanations are based upon the real motions of the heavenly bodies. The mode of ascertaining the distances and magnitudes of the heavenly bodies is so simplified that any student who understands the rule of proportion can readily comprehend it. Scientific terms and…

This textbook integrates chemistry and art with hands-on activities and fascinating demonstrations that enable students to see and understand how the science of chemistry is involved in the creation of art. It investigates such topics as color integrated with electromagnetic radiation, atoms, and ions; paints integrated with classes of matter,…

This textbook aims to divest the subject of chemistry of technicalities, and to present each natural division in a strictly practical form, illustrated by diagrams and experiments so simplified as to be within the comprehension of the youth as well as the adult. The author has observed that many of our academies and schools where chemistry is…

This textbook is a science reader. Sections include: (1) Nature and Science (cause and effect, the laws of nature); (2) Material Objects: Mineral Bodies (states of water: ice, water, steam); (3) Material Objects: Living Bodies (living plants and living animals and their ability to grow); and (4) Immaterial Objects (mental phenomenon, psychology).

This book is a collection of 28 experiments that are not meant to have any practical purpose. Each experiment, however, illustrates a scientific principle and enables students to discover how scientific facts and theories apply to seemingly useless experiments. Each experiment includes a list of materials, a series of steps, an explanation of the…

Classroom experiments on atmospheric pressure focus largely on demonstrating its existence, often in a most impressive way. A series of amusing physics demonstrations is widely known and practiced by educators teaching the topic. However, measuring the value of atmospheric pressure(P[subscript atm]) is generally done in a rather mundane way,…

The possibility of life on other worlds is one of enormous fascination. This book emphasizes how intelligence and culture helped humans form a civilization that now has the technology to detect and communicate with possible extraterrestrial civilizations. Topics discussed include indications and characteristics of intelligence, the evolutionary…

This book contains simple experiments through which students can learn about the properties of energy. These experiments include making a kitchen "volcano," a soda-pop "cannon," and a puffed-rice "scooter." Topics include: energy and work, fossil fuels, solar energy, kinetic energy, potential energy, mechanical energy, heat energy, sound energy,…

This textbook is a version of "First Course in General Science" simplified for younger pupils. There are fewer quantitative conceptions, many mathematical problems have been eliminated, and, where it has been possible without sacrificing clearness, much detail has been omitted. It discusses, in terms that the youthful mind can…

This textbook is a course on properties of heat. The first seven lectures of the course deal with "thermometric heat" and its generation and consumption in mechanical processes; the determination of the mechanical equivalent of heat; the conception of heat as molecular motion; the application of this conception to the solid, liquid, and…

This textbook presents scientific knowledge in a question-and-answer format. It is intended for the use of families and schools, explains about 2000 questions that children commonly ask, and is written in language so plain as to be understood by all. Heat, non-metallic elements, metals, organic chemistry, meteorology, optics, and sound are covered.

Discusses how early notions about celestial mechanics were restructured, one by one, involving the following concepts: the celestial sphere and its rotation; the spherical earth; planetary motion; and models for the solar system initiated by Eudoxus, Hipparchus, Ptolemy, and Copernicus. (JJK)
