Borehole Logging from Sample Collection to Borehole Geophysics
Skills and concepts that students must have mastered
How the activity is situated in the course
Content/concepts goals for this activity
- Accurate description of logged soil samples, especially of features with which the students are unfamiliar.
- Recognition of grain size variation, texture, color and mineralogy as it changes with depth.
- The integration of sample description/classification to porosity and permeability measurements or observations.
Higher order thinking skills goals for this activity
- In many cases the use of samples involves descriptive analysis and, in some cases, may involve problem solving through the integration and synthesis of previously presented material—Thinking!
- Formulation of hypotheses, especially multiple hypotheses that might explain the features described.
Other skills goals for this activity
- Note taking and sketching: How to carefully make a written description with a logical organization.
- May include oral communication of ideas and working in groups.
