Ross and Griff are over half way through their desert teaching expedition. Last week they continued instructing the Bloodstain Pattern Analysis I Class and had these reflections:
Day 3: Involved a morning discussion of the experiments conducted on Day 2. The afternoon had its own labs including drying times; horizontal motion of dropping blood; stringing for area of origin; documentation of bloodstain patterns
Day 4: Discussion of the lab experiments from Day 3 and exercises to practice measuring the widths and lengths of stains for calculating impact angles.
Day 5: In addition to new lecture topics, the class had a paper exercise to apply the use of the tangent method to calculate area of origin. They'll have more practice next week.
