Chain of infection notes
Students take notes on the chain of infection, pathogens, and the immune response, then complete the PLTW online task.

💡 Big idea: Infection transmission follows a predictable six-link chain: break any link and you stop the spread.
- 0-5 minWarm-up: name one way you have personally prevented spreading an illness.
- 5-30 minTeacher-led notes: six links of the chain of infection with examples for each.
- 30-45 minPathogen classification (bacterial, viral, fungal) and immune response overview.
- 45-55 minMap PPE and aseptic technique to specific chain links on a diagram.
- 55-75 minPLTW online activity on hospital-acquired infections (individual, self-paced).
- 75-80 minExit check: label all six links on a blank chain diagram from memory.
- • Every hospital infection that harms a patient failed at one of six points in a predictable chain.
- • Once you know the chain, you can identify exactly which intervention breaks it.
- • WebXam 072110 Handling/Preparation/Storage/Disposal strand asks you to connect PPE to transmission prevention.
- • Finish the PLTW activity today: Wednesday's case analysis uses this exact chain.
- 1Annotate the six links in the chain of infection from reservoir to susceptible host.
- 2Classify common hospital pathogens as bacterial, viral, or fungal.
- 3Outline the innate and adaptive immune responses to invading pathogens.
- 4Connect PPE and aseptic technique to specific links in the chain.
- 5Complete the assigned PLTW online activity on hospital-acquired infections.
- • Label all six links in the chain of infection accurately.
- • Submit the PLTW online task fully completed.
- • The six links of the chain of infection are: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host.
- • PPE and aseptic technique each interrupt a specific link in the chain, not the whole chain at once.
- • Innate immunity responds immediately; adaptive immunity builds targeted memory over days.

Day 2 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open myPLTW, navigate to Lesson 3.1 Nosocomial Nightmare, and find the hospital-acquired infections online activity.
Complete all questions and submit before end of period.
You submitted the bioethics reflection Monday. Today finish the full Lesson 3.1 hospital-acquired infections activity so Wednesday's case analysis uses the correct chain.
Show completion confirmation to teacher before leaving.
All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.
Today's PLTW tracker
Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

Open myPLTW, navigate to Lesson 3.1 Nosocomial Nightmare, and find the hospital-acquired infections online activity.
You submitted the bioethics reflection Monday. Today finish the full Lesson 3.1 hospital-acquired infections activity so Wednesday's case analysis uses the correct chain.
This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.
