This book presents science activities developed by teachers for children ages 3-6 years old. The activities aim to develop science skills including communication, observation, estimation, measurement, cause and effect, investigation, and evaluation in children by using their curiosity as a staring point. Activities include age suggestions, address…

Describes urinalysis techniques for dry weight measurement, examination of urinary calculi (stones), and determination of the presence of blood and blood pigments. Also presented are directions for preparing required reagents. (WB)

Outlines a procedure where chromatographic separation can be easily done and provides an introduction to column chromatography. (CS)

Describes methods for studying the direct effect of thyroid hormones on the induction of metamorphic change in amphibians. (CS)

Relates how Charles Martin Hall discovered the method of making pure aluminum metal in 1886. Retraces the events and steps that led to the process of aluminum purification. Includes diagrams of the apparatus used in the investigations. (ML)

Offers suggestions for activities that demonstrate the principles of osmosis. Explains how decalcified chicken eggs can be used to give students practice with measurement, experimental procedures, and science principles. (ML)

Describes a physical chemistry experiment that introduces undergraduate students to the entities of polyelectrolytes. (CS)

Presents a chemical instrumentation laboratory experiment that introduces the methodology of the fabrication and evaluation of an ion-selective electrode. (CS)

Presents methods by which undergraduate students gain practice in ESR spectroscopy. (CS)

Discusses electron-loss spectroscopy and the experimentally observed excitation energies in terms of qualitative MO theory. Reviews information on photoelectron spectroscopy and electron transmission spectroscopy and their relation to the occupied and unoccupied orbital levels. Focuses on teaching applications. (ML)

Outlines the objectives, materials, and procedures in performing a student laboratory experiment that demonstrates sodium transport in frog skin. (CS)

Presents three different procedures in which reagents are added in a specified order to a large beaker containing an aqueous solution of nickel sulfate. Complex ions of nickel (II) are prepared by using aqueous solutions of ammonia, ethylenediamine, dimethylglyoxime, and cyanide ion. (CS)

This list of energy resource materials is broken down into five categories: (1) general resources; (2) electricity; (3) nuclear and fossil fuels; (4) conservation; and (5) future fuels. (An added feature for New York residents is a concluding list of resources available gratis from New York electric companies). Materials cited include audiovisual…

Described is a one-week summer chemistry workshop held at Lebanon Valley College, Annville, Pennsylvania, for secondary school students. Experiments and evaluation results of the workshops are provided. (HM)

This resource guide is designed to: (1) stimulate development of student energy research projects; (2) expose students to research problems important to Ohio's science- and engineering-related industries; (3) strengthen the working relationship between science, mathematics, and English teachers in promoting technical communication skills; (4)…
