Auditory anatomy, audiograms, cochlear implants, immune response, vaccine design, herd immunity.
What to do if absent- CER:
- Claim, Evidence, Reasoning — make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure — the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities — you open it through Schoology.
Week overview - Sound and shields: audiograms, the immune response, and vaccines
Read an audiogram and connect immune response to vaccine design and herd immunity to complete Unit 1 evidence.
- 1Label a diagram of the ear, marking the cochlea and hair cells.
- 2Read a sample audiogram and identify the frequencies where hearing loss appears.
- 3Diagram a basic immune response, labeling adaptive immunity.
- 4Explain in one sentence how a vaccine trains adaptive immunity before real exposure.
- 5Use a model dataset to show how herd immunity slows disease spread as coverage rises.
- 6Assemble your Unit 1 evidence so the tracker is ready for audit.
- • You will be able to read an audiogram for hearing loss.
- • You will be able to explain how a vaccine engages adaptive immunity.
- • You will be able to describe how herd immunity protects a population.
Daily lessons this week
Open any day for its full lesson, the work due that day, and guided notes.
One CER (claim, two evidences, reasoning) on cochlear implant ethics plus a three-sentence reflection.
Labeled audiogram with threshold plots, speech banana marked, and one-sentence severity classification.
Adaptive immunity diagram, two-scenario disease-model data table, and one comparison sentence.
Two herd immunity threshold calculations with work shown, and one sentence explaining who herd immunity protects.
Unit 1 tracker audit (gap list) plus a short hearing-and-vaccine intervention recommendation for the case patient.
Quick intro to the week
- Hook: the same biology that lets you hear a whisper also decides whether a community resists an outbreak.
- Today's goal: read an audiogram and connect immunity to vaccine design while finishing your Unit 1 evidence.
- This week's Monday bioethics debate is cochlear implants, so weigh technology against identity and choice.
- Reminder: your Unit 1 tracker and all evidence are submitted in the PLTW course shell for audit.
Your PLTW coursework this week
Do this: Complete and submit the PLTW Unit 1 tracker in the online course shell with your hearing and vaccination evidence.
- • Hair cells in the cochlea convert sound into nerve signals.
- • Vaccines prime adaptive immunity so the body responds faster to real infection.
- • Read an audiogram to locate hearing loss.
- • Explain how herd immunity limits disease spread.
📋 PLTW tracker evidence due this week: completed Unit 1 tracker with audiogram analysis and vaccine and herd-immunity evidence ready for audit.
All PLTW activities are completed inside the PLTW course environment — this page only gives direction.

Lab day — what to bring & watch
This explainer accompanies the PLTW lab protocol — watch it before lab.
What to do when absent
Most days, this class is your PLTW coursework — and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.
Open Schoology (CMSD) and keep goingHow to get there: open the CMSD website, click Clever, sign in with your Microsoft (district) account, then open Schoology from Clever.
You can't do those from home — do this instead: Online case / data analysis.
Class still runs. A substitute will post today's plan — complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
