Analysis of Peppermint Leaf and Spearmint Leaf Extracts by Thin-Layer ChromatographyLibbie S. W. Pelter, Andrea Amico, Natalie Gordon, Chylah Martin, Dessalyn Sandifer, and Michael W. Pelter In this inquiry-based activity, the usefulness of thin-layer chromatography to visualize the difference between spearmint and peppermint is explored. Pelter, Libbie S. W.; Amico, Andrea; Gordon, Natalie; Martin, Chylah; Sandifer, Dessalyn; Pelter, Michael W. J. Chem. Educ.2008, 85, 133.
Dulong and Petit's Law: We Should Not Ignore Its ImportanceMary Laing and Michael Laing This article describes two student exercises: the determination of the specific heat of a metal and hence its atomic weight and a graphical study of specific heat versus atomic weight for different groups of metals and the confirmation of Dulong and Petit's law. Laing, Mary; Laing, Michael. J. Chem. Educ.2006, 83, 1499.
Phlogiston (GCMP)David M. Whisnant Phlogiston: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will think back to the last half of the 18th century when modern chemistry was beginning to take place. One of the major problems occupying chemists at the time was combustion. The dominant theory of combustion in the mid-18th century involved a substance called "phlogiston." General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
