A plant diary that compares the same feature over time

Compare the same observable feature over time.

Decide whether the record concerns height, visible leaves or another observable feature. Keeping that choice consistent makes the dated entries useful; swapping measures halfway through can create an apparent change that is really a change in method.

To hand: A supervised plant and dated record.

Choose a feature. Record regularly. Compare dates.

Choose the feature before the first entry

Keep the same measurement reference through the record. Changing from stem height to tallest leaf would create a different comparison.

Counting visible leaves provides a different record from measuring height.

Was the same feature recorded? Use prepared time-series images.

Growth is not guaranteed on a classroom timetable.
