From a writeup of a talk by John Muir Laws on nature journaling:
For each thing you record, note these three things:
Awareness: “I see…”: You notice something, draw a picture of it, make notes about it
Creativity: “It reminds me of…” (or more simply “IRMO”): You consciously seek out analogies to what you’ve seen and make notes about those
Curiosity: “I wonder…”: You ask questions or create hypotheses about what you’ve seen.
