Unit 1 Take-Home Exam: handed out today, 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: today, 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.

Today's full assignment is still due in Schoology by 11:59 PM tonight.

For today's 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

Synthesize all evidence

Thu, Oct 1, 2026 · Week 6 · Principles of Biomedical Technology (Principles of Biomedical Science)

Today's goal: Compare the six evidence threads, assess their independence and limits, and draft a supported manner-and-cause claim in the Day 16 Daily Evidence 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.

Day 16 Daily Evidence Sheet, Parts A to E

Completes: Complete the six-thread convergence table, suspect-resolution sentences, exhibit and thread count, and a supported draft claim, together with the briefing, vocabulary, and self-check tasks.

Use the practice example in your Day 16 Daily Evidence Sheet, pages 2 to 4, as a format guide. Keep its practice records separate from Case B.

For your own Part B, use all six rows: Scene, Trace, Serology and DNA, Chemistry, Medical findings, and Records. Cite E-numbers, explain what each thread supports on its own, and name any branch it weakens. Check the sources and limits before treating records as independent.

For Part C, write one paragraph naming the manner and cause only as the evidence supports them. Cite at least four exhibits across at least three threads, explain the pruning reasons, and state the strongest limitation. The count is the assignment requirement, not proof by itself. Complete Parts A, D, and E too.

Why this matters

This model shows the level of evidence and organization needed to complete: Complete the six-thread convergence table, suspect-resolution sentences, exhibit and thread count, and a supported draft claim, together with the briefing, vocabulary, and self-check tasks.

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 16, every Part complete. Submit one PDF of your Daily Evidence Sheet to Wk6 D16 · The Tree Resolves (PLTW 1.2.6). Complete every Part; finish any remaining work at home and submit by 11:59 PM tonight.

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.

Claim ceiling: Today's evidence supports a classroom claim about synthesize all evidence. It cannot prove causation, diagnose a real patient, or justify action outside this room.

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: Judging evidence reliability for synthesis

When weighing evidence streams for a conclusion, which factor most increases the reliability of a given stream?

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

Why this practice matters

It builds this reusable test skill: Judging evidence reliability for synthesis.

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.
