Botany I
The first lab session in Botany I was to familiarize yourself with the microscope.  Mr. Pride accomplished this by having us sketch a diagram of the scope we would use in the lab.  We were allowed a ruler, pencil and an eraser to accomplish this.  Below is a scan of page one in my Botany lab sketch book.
