Bio 103 - Biological Systems I

The images shown below were collected, enhanced and annotated by students in the first semester of our freshman biology course (BIO103/103L). This course involves hands-on investigation of cellular and molecular processes, as well as an introduction to the scientific method of inquiry. There is a heavy emphasis on evolutionary phenomena, both at the cellular (chromosomal genetics) and population level (Hardy-Weinberg). Students captured and annotated microscopic images of both living and prepared specimens.  The equipment used in the class was purchased with funds from an NSF ILI grant (DUE-9750521) awarded to Drs. Witz and Temple in 1997and an Alden Trust Grant awarded to them in 2006.  Images were captured with an Hitachi HP-D50 Digital Video camera (for both macroscopic and microscopic images) coupled to a Dell Pentium II Optiplex PC equipped with a frame grabber card. The images were enhanced and annotated with Image Pro Plus software. After processing, these images were compiled by students into virtual laboratory atlases. Many of the images were included in student laboratory reports.
