Visualizing chemistry
de Julie B. Ealy · Publicada por primera vez en 1995
Chemistry is an exciting science, but students can't really get excited by simply being told that a solution's color will change from red to blue, or that a white precipitate will form, or that a gas will be evolved, or that the material will begin to glow. No, they need to see these changes for themselves if they are to be excited by, and really understand, the concepts of chemistry. This useful book contains 101 demonstrations that enable teachers to illustrate the chemical principles being taught in the classroom. Topics include physical properties, reactions involving gases, energy changes, solutions and solubility, kinetics and equilibrium, acids and bases, oxidation-reduction, and electrochemistry. Each demonstration is described step by step along with safety information, a materials list, and notes on the science and history. Many of these demonstrations can be used as starting points for science fair projects. This valuable book contains a wealth of information for every chemistry teacher.
