Unit 01 · Tools, Safety & the Ethics of Dissection
This is the foundation the whole course rests on, and it comes before any specimen is opened. You learn the dissection bench by working at it: naming each instrument and using it correctly, handling sharps and cutting safely, caring for the specimen and treating the work with respect, keeping a clean and orderly station, and following a procedure while you record what you see. Mastery here is not something you can explain your way into. An instructor watches you do it, and the way you handle the tools and the specimen is the proof.
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Identifying & naming the instruments | Cannot reliably name the scalpel, dissecting scissors, probes, forceps, or pins, or say what each is for. | Names most instruments but confuses the blunt and sharp probe or reaches for the wrong tool for the cut. | Names every instrument on sight — scalpel, dissecting scissors, blunt and sharp probe, forceps, pins — and chooses the right one for each step. |
| Safe handling & cutting technique | Handles the scalpel carelessly, cuts toward the hand, or works without gloves or eye protection. | Cuts away from the body and wears protection when reminded, but still presses too hard or leaves sharps unguarded. | Keeps sharps discipline throughout — gloves and eye protection on, cutting away from self in shallow, controlled strokes, and instruments capped and set down safely. |
| Specimen care & the ethics of respectful use | Handles the specimen roughly or jokes about it, lets it dry out, and disposes of it thoughtlessly. | Handles the specimen carefully and keeps it moist when reminded, but treats the work casually. | Handles the specimen with care and keeps it moist, takes the dissection seriously, and disposes of remains mindfully and according to procedure. |
| Setting up & maintaining a clean dissection station | Works from a cluttered tray with the specimen unpinned and loses track of orientation and instruments. | Sets up the tray and pins the specimen but lets the station get disorganized or skips cleanup. | Lays out a clean tray, pins and orients the specimen correctly, keeps instruments in order during the work, and cleans up the station afterward. |
| Following a procedure & recording observations | Ignores the procedure and records nothing, or writes down guesses instead of observations. | Follows the steps in order but records observations sparsely or out of sequence. | Works through the procedure step by step and records clear, accurate observations of what is actually on the specimen as the work proceeds. |
| Integration (cross-domain) | Treats the science as isolated facts; makes no cross-domain connection. | Names a link to history, reading, or writing but cannot defend why it matters. | Connects the unit to its anchor across History · Reading · Writing (plus chosen electives) and defends why the connection matters. |
“I laid out the tray, pinned the specimen down, and kept everything moist. I named each tool as I picked it up — scalpel for the first shallow cut, blunt probe to separate tissue without tearing it — and I always cut away from my hand with gloves and goggles on. I wrote down what I saw at each step, and I’ll dispose of the specimen the way the procedure says.”
“I think this one’s the scissors? I just started cutting — kind of toward myself — and it got dry and messy. I didn’t really write anything down.”
You demonstrate this unit by doing it while an instructor watches — setting up the station, naming and handling the instruments safely, caring for the specimen, and following a procedure — not a written test. A criterion counts as mastered only when you can perform the technique cleanly and treat the tools and the specimen with the respect the work requires. Mastery is demonstrated, not awarded.
