Garrett Participates in ACS Science Coaches Program

Through her work with the American Chemical Society (ACS) Science Coaches program, Dr. Danielle Garrett, assistant professor of chemistry education, recently spent time teaching 4th grade students at Donelson Christian Academy about wavelength and visible light.  In her lesson “Wavelength Analysis of LEDs using Handheld Spectroscopes,” forty-nine 4th grade students engaged in a lab activity to determine the wavelength of red, yellow, green and blue LEDs.

Based on their measurements and class discussions about the relationship among wavelength, frequency and energy, students were challenged to make predictions about the wavelengths of other colors of visible light. This is the 3rd year that Garrett has partnered with 4th grade teacher Ellen Deathridge through the ACS Science Coaches Program.
