The front of every student binder. Good studying is not about more hours — it is about placing the right hours at the right distance apart. This cycle turns retrieval practice and spaced practice into a fixed weekly cadence built around the course’s two anchors: Concept Day (a new idea is taught) and Experiment Day (that idea is tested at the bench).

The seven-day cycle

The weekdays will shift with your schedule — what matters is the spacing, not the calendar. Write your own days into the first column.

Real laboratories run on checklists. Run all three sections, top to bottom, before any evidence is handled or any test is run. A box left unchecked is a reason to pause, not a thing to skip.

Safety — non-negotiable

• Eye protection on — splash-rated, over the eyes (not on the forehead), the entire session.
• Gloves on — nitrile, intact, the right size, whenever handling evidence, developer chemicals, or simulated biological samples.
• Ventilation confirmed — window open or hood running before superglue fuming or opening volatile developers and chromatography solvents.
• Contamination protocol set — fresh gloves for each item; simulated blood and body-fluid work treated as biohazard; a spill kit within reach.
• Hand-washing planned — soap and water available; wash at the end before food or face.
• Spill, fire & first-aid known — you know where the extinguisher, eyewash, towels, and sink are before you need them.

Setup — a ready bench

• Evidence kit & test reagents ready — powders, lift cards, chromatography paper, developing solvents, and presumptive-test reagents clean, located, and in order.
• Instruments checked — comparison microscope focused and clean, hand lens ready, calipers and the UV / alternate-light source calibrated and working.
• Case notebook open — to a fresh, dated page before work begins.
• Reagents & samples labeled — every developer, solvent, and known sample labeled with name and date; nothing unlabeled is ever used.
• Tools laid out — brushes, lift tape, forceps, evidence bags, markers, and the chain-of-custody log within reach.
• Workspace clear — bench wiped, bags and coats off the surface.

Readiness — the mind, not the bench

• Pre-read done — the procedure read start to finish; no surprises mid-experiment.
• Today’s objective known — you can state, in one sentence, the question this experiment answers.
• Demonstration target clear — you know what result, measurement, or skill counts as success.
• Prediction written — a one-line hypothesis: what you expect to see, and why.

A real scientist’s notebook is a contemporaneous, permanent record — written during the work, in ink, never erased, never recopied “neatly” later. The single rule: if it is not in the notebook, it did not happen.

Writing it the right way

• Write in ink, during the work — notebooks are not recopied later; the in-the-moment record is the value.
• Never erase — one line through a mistake, correction beside it. The crossed-out attempt is data too.
• Record what you measured, not what the textbook predicts — your readings prove you ran the experiment.
• Leave nothing for “later” — analysis and conclusion are written the same day, while it is fresh.
