Book Description
Excerpt from A Guide to Elementary Chemistry for Beginners I know of but one way to teach a student how to acquire a real knowledge of nature, and that is, to fix his mind habit ually on things and events brought under his own eye, and direct him to the discovery of facts and principles for himself. The use of apparatus is, of course, indispensable if the student is thus to study phenomena instead of descriptions of phenomena, and the use of apparatus, by himself, is with out doubt the method which is most certain to stimulate his mind to the greatest activity. Laboratory study for students in high schools is rapidly growing in favor, but unfortunately, in many schools where chemistry is taught, the difficulties in the way of this method are still thought to be real. Even in these, chemistry to be truly useful should be presented as a study of phenomena, by experiments, instead of what some body has said about phenomena in books. I have therefore tried to construct a course of experiments suited to the use of the beginner, at his laboratory desk, and to the use of the teacher for his class of beginners, where facilities for students to work for themselves seem to be out of reach.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1886 edition. Excerpt: ... agree with these in being soft, light, and combustible on water. Yet in some things they do agree quite closely. For example: Potassium forms the oxide K20 Copper" "Cu2O Silver" "Ag2O In these compounds the atoms of potassium, copper, and silver hold the same relation to oxygen. And the order of their atomic weights brings them together in the same group in the spiral. The Vacant Places.--There are many vacant places in the spiral: what is the meaning of these gaps? They lead us to think that the elements are not yet all discovered. When the table was first made there was a vacant place where gallium, Ga, now stands in the third group. Mendelejeff said that there ought to be an element whose "atomic weight is about 69, its specific gravity about 6, and its atomic volume about 11.5," to fill this gap. Afterward gallium was discovered. Its atomic weight proved to be 69.8, its specific gravity 5.9, and its atomic volume 11.8. From its vacant place in the table, Mendelejeff was able to give the properties of this metal before it had been discovered. He did the same thing for the element scandium, Sc, also in the third group. Possibly other elements are yet to be discovered by which other gaps will be filled. the analytical system. Classification Founded on Solubility.--We have found that hydrochloric acid will give a precipitate if mixed with a solution of a compound of silver, Ex. 193, but none if mixed with a solution of a compound of copper, Ex. 185. This is because silver chloride is insoluble in the liquid used, while copper chloride is soluble. Now all metals whose chlorides are insoluble, like that of silver, can be put with silver to form one group. Such differences in solubility throw the metals together into classes called the...

Book Description
Chemistry For Dummies, 2nd Edition (9781119293460) was previously published as Chemistry For Dummies, 2nd Edition (9781118007303). While this version features a new Dummies cover and design, the content is the same as the prior release and should not be considered a new or updated product. See how chemistry works in everything from soaps to medicines to petroleum We're all natural born chemists. Every time we cook, clean, take a shower, drive a car, use a solvent (such as nail polish remover), or perform any of the countless everyday activities that involve complex chemical reactions we're doing chemistry! So why do so many of us desperately resist learning chemistry when we're young? Now there's a fun, easy way to learn basic chemistry. Whether you're studying chemistry in school and you're looking for a little help making sense of what's being taught in class, or you're just into learning new things, Chemistry For Dummies gets you rolling with all the basics of matter and energy, atoms and molecules, acids and bases, and much more! Tracks a typical chemistry course, giving you step-by-step lessons you can easily grasp Packed with basic chemistry principles and time-saving tips from chemistry professors Real-world examples provide everyday context for complicated topics Full of modern, relevant examples and updated to mirror current teaching methods and classroom protocols, Chemistry For Dummies puts you on the fast-track to mastering the basics of chemistry.

Science Starters: Elementary Chemistry and Physics Course Description This is the suggested course sequence that allows one core area of science to be studied per semester. You can change the sequence of the semesters per the needs or interests of your student; materials for each semester are independent of one another to allow flexibility. Semester 1: Chemistry Investigate the Possibilities Elementary Chemistry-Matter Its Properties & Its Changes: Infused with fun activities and applied learning, this dynamic, full-color book provides over 20 great ways to learn about bubbles, water colors, salt, and the periodic table, all through interactive lessons that ground students in their faith in God. Help tap into the natural curiosity of young learners with activities that utilize common household items and teach them why and how things work, what things are made of, and where they came from. Students will learn about the physical properties of chemical substances, why adding heat causes most chemical changes to react faster, the scientist who organized a chart of the known elements, and the difference between chemical changes and physical changes. Semester 2: Physics Investigate the Possibilities Elementary Physics-Energy Its Forms, Changes, & Function: This remarkable, full-color book is filled with experiments and hands-on activities, helping 3rd to 6th graders learn how and why magnets work, different kinds of energy from wind to waves, and concepts from nuclear power to solar energy. Science comes alive as students are guided through simplified key concepts of elementary physics and hands-on applications. Students will discover what happens to light waves when we see different colors, how you can see an invisible magnetic field, the essential parts of an electric circuit, and how solar energy can be changed into electric energy. Investigate the wonderful world God has made with science that is both exciting and educationally outstanding in this comprehensive series!
