Unit 1 Take-Home Exam: handed out Thursday, October 1, due Monday, October 5 at the start of class

The printed take-home exam replaces the in-class Unit 1 Test. Work in pen and turn in the paper packet at the start of class on Monday, October 5. Paper only: nothing is uploaded. It is worth 1000 points in four sections:

Section A (400 points): multiple choice, open notes (320 points), then the Thinking Check on how sure you were and why the tempting wrong answers are wrong (80 points).
Section B (250 points): Your evidence. Answer three questions from your own case records and cite where each record is, such as an exhibit number.
Section C (200 points): Draw the mechanism. Make one hand-drawn, labeled drawing of what happened inside the body (100 points) and write a paragraph that walks its arrows (100 points).
Section D (150 points): Watch my thinking. Your in-class first try and its revision, one honest confusion, and your AI Use Log.

First try in class: on handout day, Thursday, October 1, the first 5 minutes go to packet page 2, START HERE IN CLASS, in pen, with no notes, and Mr. Mendoza initials it before you leave. Absent on handout day? Do it in class on the day you return.

Using AI: AI may explain a concept, quiz you, or define a word, and every use goes in your AI Use Log. Do not paste an exam question into AI, do not copy an AI answer, and do not let AI write any part of Sections B, C or D.

Turn-in talk: Every student has a short talk, about 2 minutes, with Mr. Mendoza about two or three of their answers when they turn in the exam on Monday, October 5. This is not a punishment. If you did not log AI use, or your answers do not match your class work, the talk takes longer.

The full assignment on Thursday, October 1 is still due in Schoology by 11:59 PM that night.

For the Thursday, October 1 evidence sheet, the 11:59 PM deadline replaces the printed instruction to hand it in before leaving class. Complete every Part.

Study with the Unit 1 Test Preparation page: work its three sittings (skills, flashcards and two self-checking quizzes) as you prepare for Section A, and use its skills checklist and glossary to check your own explanations. The study guide and practice test, with its own answer explanations, are there too.

Here's an example of what's due today

Analyze histology evidence

Wed, Sep 30, 2026 · Week 6 · Principles of Biomedical Technology (Principles of Biomedical Science)

Today's goal: Compare the Case B tissue slides with healthy references and explain the supported patterns and limits in Parts A to E of the Day 14 sheet.

What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Daily Evidence Sheet, Day 14: complete Parts A to E.

Completes: Part A: read the briefing and answer A1 and A2, citing the reading as the sheet asks. Part B: complete the slide call table (B1); compare visible differences with the healthy reference (B2); calculate the cell width in millimeters and micrometers and state its precision (B3). Part C: write the histology paragraph for two slides: description, pattern and Day 13 finding, followed by the mechanism-versus-manner limit. Part D: use histology and edema in sentences about your work. Part E: answer all three self-check questions, then check every Part of your sheet.

Use the worked example in the Case B Day 14 Daily Evidence Sheet as your format guide. Its practice case is separate from your own case.

Part B: complete the slide call table (B1); compare visible differences with the healthy reference (B2); calculate the cell width in millimeters and micrometers and state its precision (B3).

Part C: write the histology paragraph for two slides: description, pattern and Day 13 finding, followed by the mechanism-versus-manner limit.

Tissue findings can support a mechanism; they do not establish the manner of death. State what remains uncertain. Complete Parts A, D and E too.

Why this matters

This model shows the level of evidence and organization needed to complete: Part A: read the briefing and answer A1 and A2, citing the reading as the sheet asks. Part B: complete the slide call table (B1); compare visible differences with the healthy reference (B2); calculate the cell width in millimeters and micrometers and state its precision (B3). Part C: write the histology paragraph for two slides: description, pattern and Day 13 finding, followed by the mechanism-versus-manner limit. Part D: use histology and edema in sentences about your work. Part E: answer all three self-check questions, then check every Part of your sheet.

Build yours step by step

Date and label the entry.
Record the procedure, observation, or design decision clearly.
End with what the evidence means and the next step.

Change it for a new task

Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.

Turn in: Daily Evidence Sheet, Day 14: complete Parts A to E. Submit one PDF of your complete Day 14 Daily Evidence Sheet to Wk6 D14 · The Fabric Under the Lens (PLTW 1.2.4) in Schoology by 11:59 PM tonight. Keep the named notebook pages in your Investigative Notebook.

Go to Schoology to turn this in.

Submit one PDF. Schoology attaches your name to your upload; on the page itself, write your period and code. Name the file: FirstName LastName - Assignment Title - YYYY-MM-DD.pdf.

WebXam problem for today's skill

One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

WebXam-style domain: Biotechnology Research and ExperimentsSelf-check skill: Interpreting histology by comparison to normal reference tissue

A pathology student says a tissue slide looks abnormal but has no normal reference image to compare it to. Why does this weaken the interpretation?

Tap an answer to see the full explanation. Nothing is recorded or graded.

Why this practice matters

It builds this reusable test skill: Interpreting histology by comparison to normal reference tissue.

Use it on a new WebXam question

Name the concept or data pattern being tested.
Cross out choices that violate that rule or the evidence.
Justify the best remaining choice before checking the answer.
