Unit 3.2 Body Guards: immune system modeling, the vaccine data CER, then pathogen transmission and the plaque assay with the eye dissection.
Your PLTW coursework: Human Body Systems ▸ Unit 3: Adventure Awaits ▸ Lesson 3.2 Body Guards ▸ "Activity 3.2.1 Powers of Protection", "Activity 3.2.2 Immune Defense"
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. Find it in Clever with your Microsoft sign-in, right next to Schoology.
Model how the and adaptive immune systems respond to a , including the - match and the role of vaccines.
- 1List the body's outer defenses, starting with the skin, and explain how each blocks pathogens.
- 2Define , , , , and adaptive in your notebook.
- 3Build a model showing a entering the body and triggering the response first.
- 4Add the adaptive response and show how an matches a specific .
- 5Use your model to explain how a prepares the immune system in advance.
- 6Summarize the difference between the and adaptive responses in two sentences.
- • You will be able to describe how skin and the lymphatic system defend the body.
- • You will be able to model the - match in an .
- • You will be able to explain how a builds .

Plaque-count with percent reduction calculated per condition, plus a labeled eye-structure diagram noting one structure vulnerable to viral infection.
- Hook: every second your body fends off invaders you never notice, and today you build the model that shows how.
- Today's goal: model the from skin barrier to match and explain how vaccines fit in.
- This week's Monday bioethics debate: should vaccination be required to protect a whole community?
- Reminder: your graded immune defense model lives in the PLTW course shell, not on loose paper.
Do this: Advance the PLTW Body Guards benchmark by completing the online evidence on the immune and lymphatic systems in the course shell.
- • Skin and the lymphatic system are part of the body's layered defenses.
- • The response is fast and general; the adaptive response is specific and remembered.
- • Antibodies bind specific antigens, and vaccines prime this response in advance.
- • Model the and adaptive immune responses to a .
- • Explain how a produces .

Fiction. There is no such student. The lessons, labs and dates are the real planned course; the student, the classmates and the conversations are invented.
This explainer accompanies the PLTW lab protocol: watch it before lab.
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 Clever, then myPLTWSign in to Clever with your district Microsoft account to open Schoology or myPLTW. Follow today's posted steps. If myPLTW will not open, use the posted alternative and tell Mr. Mendoza. Turn in your completed work through the Schoology assignment.
You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: immune system.
