5-Day Unit: Diagnostic Services & Health Informatics
8th Grade CTE
Class Size: 8 Students
Learning Objectives
Identify roles in Diagnostic Services (Radiology, Lab, etc.)
Define Health Informatics and its role in patient care.

Clear Tape / Scissors
Part 1: Diagnostic Services
Day 1: The Lab Technicians
50 MIN
5-Min Warmup
"The Mystery Sample": Show a picture of three clear liquids. One has a faint pink tint. Ask: "If these were lab samples, what might that color change tell us?"
Activity: Pipette-Free Pipetting
Students simulate lab testing using markers and water. They "swab" a paper "patient sample" and see how colors spread to identify a "pathogen" based on a color key.
Day 2: Imaging Investigators
50 MIN
5-Min Warmup
"Negative Space": Show an image in inverted colors. Ask students to identify common objects (a fork, a key, a phone) to simulate looking at X-rays.
Activity: The Tracing Room
Using thin paper (standard printer paper held to light), students "trace" hidden bone structures drawn on the back of a page to identify "fractures" marked in pencil.
Part 2: Health Informatics
Day 3: The Data Analysts
50 MIN
5-Min Warmup
"The Secret Code": Give students a sequence of numbers (e.g., 04132026). Ask: "In a medical file, what could this mean?" (DOB, Admission Date, ID Number).
Activity: Binary Bio-Data
Students convert simple patient info (Age, Temperature, Heart Rate) into a "symbolic code" using stickers or shapes to represent different health ranges.
Day 4: EHR Architects
50 MIN
5-Min Warmup
"Privacy Patrol": Show a sample medical form. Ask students to find 3 pieces of "PHI" (Protected Health Information) that should be redacted.
Activity: The File Rescue
Students receive a "scrambled" patient file (scraps of paper) and must organize them into a Manilla folder according to informatics standards: Personal, Clinical, and Billing.
Part 3: Synthesis
Day 5: Career Crossroads
50 MIN
5-Min Warmup
"The Dream Team": Ask students: "If you were opening a hospital, which detective (Diagnostic or Informatics) would you hire first? Why?"
Activity: Medical Detective Case Final
Students solve a final mystery case using the skills from Days 1-4. They must fill out a lab report and enter the data into a "paper tablet" database.
Differentiation: 4th Grade Level
For the Junior Detective Handbook :
Focus on concrete roles (X-ray taker vs. Data person).
Replace complex medical terminology with descriptive words (e.g., "bone photo" instead of "radiograph").
Reduce data entry tasks to simple sorting and color-matching.
Provide larger writing spaces and visual prompts.

Day 1: Lab Analysis
1. Observation: Students should identify the color change based on the marker used (e.g., Red = Bacterial, Blue = Viral).
2. Connection: Medical Laboratory Technician (MLT), Clinical Laboratory Scientist, or Pathologist.
Day 2: Imaging Intelligence
3. Diagnosis: Students should describe a specific fracture (e.g., "The Radius has a hairline fracture").
4. Connection: Radiologist (MD) or Radiologic Technologist. Pattern recognition is vital to spot subtle abnormalities that others might miss.

6. Ethics Connection: Data security protects patient identity and prevents discrimination or identity theft.
Day 5: Synthesis (Case Closed)
Students should integrate their findings. A successful summary includes a mention of both the physical cause (from Diagnostic) and the data trend (from Informatics).
Example Discharge Note: "Patient presented with a hairline fracture (Day 2) and viral symptoms (Day 1). Informatics reports high heart rate (Day 3), suggesting stress on the body."

Lab Swab Facilitation Guide LAB SWAB PROCEDURES
Activity Guide: Day 1 - Pathogen Analysis
Activity Vocabulary
Chromatography: Separating a mixture by passing it through a medium (like paper).
Pathogen: A germ (virus or bacteria) that causes disease.
Solvent: The liquid (water) used to dissolve the ink and help it travel.
MLT: Medical Lab Technician; the professional who runs these tests.
Teacher Prep (10 Minutes)
Prepare the "Patient Samples" before class. Use standard Washable Markers on printer paper strips (approx 2" x 6").
Bacterial Sample
Draw a solid 1/4" dot of Red marker in the center. Label "Sample A".
Viral Sample
Draw a solid 1/4" dot of Blue marker in the center. Label "Sample B".
Healthy Sample
Draw a solid 1/4" dot of Yellow marker in the center. Label "Sample C".
Student Lab Protocol
1
Preparation
Fill a small cup with 1/2 inch of water. Tape your sample strip to a pencil so the bottom edge just touches the water level.
2
The Reaction
As water climbs the paper (capillary action), it will hit the marker dot. Let it run for 3-5 minutes until the color spreads significantly.
3
Data Entry
Remove the strip and place it on a paper towel. Record the final color in your Case File. Does it match Red (Bacterial), Blue (Viral), or Yellow (Healthy)?
Scientific Why
Ink is often made of multiple colors. As water travels, lighter molecules move faster and farther than heavier ones. This "separates" the mixture so we can see what's inside.
Career Link
MLTs use chromatography to detect drugs, toxins, or specific proteins in patient samples. Accurate observation is the difference between a right and wrong diagnosis.
4th Grade Modification
Use coffee filters instead of printer paper. The color spreads into a "flower" shape much faster. Instead of measuring water, let them use a spray bottle to "mist" the marker dot and watch the colors bloom.
