Why a checklist before every lab
The student learning pathways use supplied images, models, and explicitly synthetic records. Prepare by recording the selected level, source, question, and model assumptions. A dataset is not a performed lab and a checklist is not authorization for a medical procedure.
No personal measurements, exercise challenges, breath-holding, invasive tests, real patient uploads, or treatment/dosing tasks are assigned. No reproductive or health disclosure is required. Any separate demonstration must be instructor-approved, noninvasive, and have a non-personal model/record alternative agreed before instruction.
Know what evidence you are using, what it can establish, and what it cannot authorize.
1 — Safety
Confirm the safeguards relevant to the declared task. If equipment, prepared slides, or an existing specimen activity are separately approved, follow that activity’s reviewed facility procedure; these pages supply no handling authorization.
- The instructor has approved the task, supervision, required equipment, and alternative; a learner can use supplied records without health disclosure.
- No classmates, patients, bodily-fluid samples, wounds, cultures, or private records are used as study data.
- No challenge is performed to change heart rate, breathing, sweating, hydration, or electrolyte state.
- For a separately approved materials activity, required protective equipment, hazard/SDS review, facility controls, and disposal are confirmed by the instructor.
- Missing approval or equipment means use the agreed alternative or pause; do not improvise a procedure from an AI response.
2 — Setup
Arrange the approved sources and materials so observations and inferences remain separate.
- The assigned source section, selected level, and task read before beginning.
- Models, prepared reference images, and data records have source labels and readable scales.
- All necessary inputs and units are supplied; missing values are recorded as missing, not invented.
- Microscope handling, if separately assigned, is observed by the instructor; a provided image is labeled as an interpretation alternative.
- The learner knows which five science criteria are being practiced and that this task adds no required practical.
- Lab notebook open to a fresh, dated page with the title and question already written.
3 — Readiness: the pre-lab questions
Before analyzing a record or examining an approved model, answer these in your own words or an agreed accessible format.
- What is the question? State, in one sentence, what this lab is trying to find out, identify, or measure.
- What is the anatomy? Name the structures or the physiological relationship the lab depends on.
- What is my prediction? A specific model expectation — a visible tissue feature, transport direction, or calculated response under stated assumptions.
- What am I recording, and in what units? Name every structure or quantity you will record, its unit where it has one, and its uncertainty.
- What could go wrong? Identify the one or two steps most likely to introduce error, and how you will minimize them.
- What does success look like? Know, before you begin, what a reasonable result would be — so an absurd number raises a flag at the bench, not a week later.
A student who answers all six is not guessing their way through a recipe — they are running a lab they understand, with a result they can already roughly predict. That is exactly the readiness the lab-notebook entry is built to capture, and the kind of preparation a lab defense is designed to reward.
