Phrase a question that can be observed

Write the question so that its key terms can be connected to observations. “Are shaded pool edges cooler than exposed edges during the same visit?” identifies a comparison, a setting, and a measurable variable. “Why is one pool better?” is too broad unless “better” is defined in terms the field work can assess.

A question does not need to be ambitious to be useful. A narrow question can guide where and when to take measurements, while limiting the conclusions to the sampled places and conditions. Record the date the question was framed so later notes can distinguish the initial idea from a question revised after seeing results.

List evidence that bears on it

Under the question, list observations that could support it and those that could challenge it. For the shaded-edge example, useful evidence might include paired temperature readings, time, depth, and a description of shade at each point. A result in the opposite direction would also matter; the notebook should make room for evidence that does not fit the expectation.

Define the comparison before collecting data where practical. If one point is measured in direct sun and another in shade, try to keep timing and depth similar or record differences that could affect interpretation. The goal is not to eliminate every field variation, but to make the relevant conditions visible.

Separate prediction from observation

A prediction is an expectation, not a result. Label it as such: “Prediction: shaded edge will read lower at matched depth.” Then record measurements independently, even when they contradict the prediction. This separation helps prevent later memory from reshaping the original data to fit a preferred explanation.

If an unexpected observation suggests a revised question, preserve the earlier wording and add the new version with a date or version marker. For example, repeated readings may prompt a question about time of day rather than shade alone. Keeping both versions clarifies how the investigation developed.

End with limits and next steps

Note what the observations cannot establish. A few readings from one visit can describe those sampled conditions, but may not characterize all pools or seasons. State what additional observations would strengthen the comparison, such as repeated visits or a larger set of matched locations.

A research question in a notebook should guide attention while staying open to correction. When the question, relevant evidence, and limits are written together, later analysis has a clear and honest starting point.
