Niewahner, J. H.; Walters, Keith A. – Journal of Chemical Education, 2007
A detailed description of the synthesis of bis(1,2-dimethylimidazole)copper(I) hexafluorophosphate by using techniques in a glove box is presented. The results shows that the synthesis of the copper complex has a distinct color change indicating by-product oxidation by oxygen.

Shaji, Milimu Gladys; Indoshi, Francis C. – Contemporary Issues in Early Childhood, 2008
Cognitive development and teaching have highlighted the importance of learning based on the relationship among individuals and the learning environment. Teaching and learning of science in early childhood development and education (ECDE) can only be effective if adequate facilities, materials, equipment and activities are put in place. Teaching of…

Iannone, Mark – Journal of Chemical Education, 2006
An alternative method that uses a simple apparatus to measure vapor pressure versus temperature in a closed system, in which the total pressure is the vapor pressure of the liquid sample, is described. The use of this apparatus gives students a more direct picture of vapor pressure than the isoteniscope method and results have generally been quite…

Carroll, H.; And Others – 1972
An ozone detector was built and evaluated for its applicability in smog chamber studies. The detection method is based on reaction of ozone with ethylene and measurement of resultant chemiluminescence. In the first phase of evaluation, the detector's response to ozone was studied as a function of several instrument parameters, and optimum…

Hiebert, Sara M; Noveral, Jocelyne – Advances in Physiology Education, 2007
This investigative laboratory exercise uses the different relations between ambient temperature and metabolic rate in endotherms and ectotherms as a core concept to answer the following question: What thermoregulatory mode is employed by chicken embryos? Emphasis is placed on the physiological concepts that can be taught with this exercise,…
