Field science (野外科学)

= outdoor science, which means one of the sciences, mainly researhced in outdoors

Field biology (野外生物学)

= fundamentals of ecology
  1. Observations in natural field → catch the fact (phenomena)
  2. Experiment under controlled conditions → demonstrate the fact
Notes on field trips (野外実習)
The purposes of the trips are field observation for education, often non-experimental researches.

To observe the subject in its natural state and possibly collect samples
