Boring Logs and Soil Profiles

During a recitation period, the students are divided into groups to evaluate 15 clear acrylic tubes filled with soil, representing 15 split spoon samples collected during a site investigation. Students are informed that the 15 samples were acquired from three drilled borings. Each acrylic tube is labeled with surface elevation, sample depth, visual soil classification, boring number, and blow count information. Groups use the information on the samples to fill in information on boring logs given to each student. The transfer of information from real samples to the logs simulates the process conducted in the field by the technician and enables the students to see what field soils look like. Students are then expected to create a soil profile (a two dimensional view of the subsurface) from their newly created boring logs.
