October--Pigments, leaves, and fall colors
Dr. Soren Brauner, Department of Biology/Toxicology, Environmental Science Program
(sbrauner@ashland.edu)
The lab activities will entail using paper chromatography to separate the photosynthetic pigments, use of spectrophotometers to determine the wavelengths of light being absorbed by photosynthesis, and microscopic examination of leaves to observe where the pigments (red, green, and yellow) are located.

December--Chemistry of esters
Dr. Brian Mohney, Department of Chemistry, Geology, and Physics

In this lab we look at esters, a class of chemical compounds that provide the aroma and taste to many foods. A number of esters are synthesized in the lab, and we demonstrate how these can be analyzed with equipment such as the gas chromatograph-mass spectrometer.
