Observation journal
See it
A useful journal separates observation, interpretation, action, and outcome. ‘Leaves appear translucent’ is an observation; ‘hyperhydricity suspected’ is an interpretation; ‘isolated batch for review’ is an action; later recovery or decline is an outcome.
Understand it
Use dates and batch identifiers.
Photographs are stronger when paired with written context.
Preserve original notes instead of rewriting history after the outcome is known.
Important boundary
Do not erase an incorrect hypothesis; mark it as superseded by later evidence.
Try it
Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.

Connect this lesson to an actual MyTCLab record: what fields would you need in order to know later exactly what happened and why?
