Topic Overview
Focuses on the major regions of the brain and their functions, as well as the mechanisms of sensory perception.
Key Questions
- ?Analyze the specialized functions of different regions of the human brain.
- ?Explain how sensory receptors convert external stimuli into nerve impulses.
- ?Predict the functional consequences of damage to specific areas of the brain.
About the Methodology
Groups receive a detailed case study: a specific historical event, decision, or situation, with background information, key actors, and data. They analyze the case using a structured framework (identify the problem, evaluate options, recommend a course of action, justify their reasoning). Develops analytical thinking and decision-making skills.

Fun Factor
Peak Energy Moment
The 'Breaking News' alert creates an immediate sense of urgency and importance.
The Surprise
The realization that Patient C (Sam) had symptoms before school started, making them the silent carrier who infected the bus.
What to Expect
Students will likely get competitive about being the first to 'crack the code' of the transmission map.

Read Aloud
Breaking News: St. Jude's High School has reported a sudden spike in respiratory illness. Within 48 hours, 12 students and 2 staff members have been sent home with fever, fatigue, and a distinctive 'barking' cough. Local health officials are baffled because the symptoms don't match the seasonal flu. The school cafeteria, gym, and library are now closed. We need a team of epidemiologists to find Patient Zero before the entire district is compromised.
Teacher Notes
Read this with high energy. If possible, project a fake news headline on the board to set the mood.
Briefing
10 min
You are now Lead Investigators for the CDC. Your goal is to analyze patient files to find the source of the infection and explain how the students' immune systems are fighting back. You will map the transmission chain and identify the biological 'red flags' in their blood work.
Group Formation
Organize students into 'Epidemiology Units' of 3 members each.
Materials Needed
- •Case File: Outbreak Alpha
- •Epidemiological Investigation Worksheet
- •Transmission Map Template
- •Immune Response Diagram
- •Final Report Template
Action
30 min • 100% Physical
17 min
Review the 8 Patient Files. Record symptoms, time of onset, and recent locations for each individual on your Investigation Worksheet.
Encourage students to look for the earliest 'Time of Onset' to narrow down Patient Zero.
28 min
Construct the Transmission Map. Draw lines between patients based on shared locations (Cafeteria, Gym, Bus 42) to visualize how the pathogen traveled.
Watch for students who miss the 'Bus 42' connection; it is the hidden link.
37 min
Analyze blood work data. Use the provided white blood cell counts to determine if the infection is viral or bacterial and label the Immune Response Diagram.
Remind them that high neutrophils often suggest bacteria, while high lymphocytes suggest viruses.
48 min
Synthesize findings into the Final Report. Identify Patient Zero, the mode of transmission, and the specific immune cells involved in the primary response.
Ensure they justify their choice of Patient Zero with at least two pieces of evidence.
If things go sideways
- ▸If a group is stuck, point them toward Patient C's travel history to the airport.
- ▸Check that groups understand the difference between 'symptoms' and 'asymptomatic' carriers.
- ▸Provide a 'Transmission Key' if students struggle to connect the dots on the map.
Differentiation Tips
- ▸Advanced: Ask students to calculate the R0 (basic reproduction number) for this specific outbreak.
- ▸Struggling: Provide a pre-filled timeline with the first three patients already plotted.
- ▸ELL: Use a visual glossary for terms like 'onset', 'fatigue', and 'transmission'.

5 min
Discussion Questions
- 1
Why was Patient Zero difficult to find initially?
- 2
How did the innate immune system respond differently than the adaptive system in these patients?
- 3
What public health measures would you recommend based on the transmission map?
Exit Ticket
Identify one specific white blood cell involved in the 'search and destroy' phase of this outbreak and describe its role.
Connection to Next Lesson
Next session, we will explore how vaccines 'train' the immune system to prevent an outbreak like this from starting.
