MODEL-1: a separate practice record

These supplied values belong to a stairwell practice scene, not Case A or B. A patch about 6 cm across on the third step tread reportedly fluoresced under the lamp. No material identification is supplied.

Identifier: MODEL-1, E2-step3
Reference points: RP1: fire-door frame at the landing. RP2: handrail's bottom post.
Location: 138 cm from RP1, 96 cm from RP2, on the third step tread
Photo references: W-04 and UV-01, both with scale. Earlier white-light references: W-01, W-02, W-03.
Handling: evidence officer; 3:14 PM; received by intake.
Status: custody row opened at bagging

A four-sentence practice correction

The MODEL-1 record reports fluorescence on the third step. That light response does not identify the material. The intake entry should preserve the reported location and photo references without changing the item description to blood. An identification claim would need a method appropriate for the material and its actual result, which this practice record does not supply.

Use the shape to understand Part C. Write your own response from your case record. Do not copy MODEL-1 numbers into it.

1. Read the source

2. Keep the item fields together

3. Mark limits and missing fields

4. Submit one intake sheet

F1. A record-review workflow. Teaching illustration, not a scene photograph or test result.

Start with the supplied source. Keep the identifier, location, photo references and handling status together. State limits or missing information. Finish the single Parts A–E intake sheet.

Connection to PLTW

Related PLTW reference: Principles of Biomedical Science, Activity 1.1.1 A Sketchy Scene. This John Hay record exercise practices connected documentation skills. It does not by itself complete the official activity.

Complete the assigned D06 sheet here. Record official PLTW completion only when the teacher assigns and verifies the actual activity requirements.

Turn in one sheet

Hand in the paper sheet or submit one PDF of the same completed sheet to your section's Schoology assignment by September 14 at 11:59 PM. Include continuation rows in that same submission. Submit once.

No separate microscopy drawing, new scene photograph, scale sketch, group document, extra CER or exit ticket is required. Notebook work stays in the notebook.

Case A: submit to the D06 assignment

Keep your intake sheet for Tuesday's trace-comparison work. It records the source and limits of the information you will use.

Sources and optional background

Everything needed is supplied in the reading, model and own-case records. These links are optional background, not hidden answer locations.

Today's records cannot identify a substance, person, cause of death or responsible suspect. They describe reported observations and handling. A copied photo reference does not mean you viewed its image.
