College of Science and Mathematics Hosts Local High School Class

Students from Father Ryan learn from Belmont professorsThe College of Sciences and Mathematics had the pleasure of hosting Father Ryan High School’s Honors Bio Technology class on March 10 Dr. Neelie Crooke and her class partnered with Drs. Thom Spence and Nick Ragsdale as they explored the skill of thin layer chromatography (TLC), extraction of pure chlorophyll and spectrometry. The class learned the science behind and the technique of TLC and visible light spectrometry as they separated chlorophylls a and b from the other photo pigments and determined the absorbance spectra of these plant photo-pigments. After attaining their data, the group worked on determining the concentration and percent make-up of chlorophylls in a spinach leaf. Finally, Dr. Crooke and her class toured the science labs on the 3rd and 4th floors of the Jane Ayers Academic Center.
