Facilitator Guide -- Health Systems Literacy
Please also read the Facilitator Safety Guide before running lessons. This curriculum requires careful facilitation around body image, eating, and health claims.
Purpose
Health Systems Literacy teaches children ages 8-12 to understand the human body as a biological system: how homeostasis works, how food and sleep support the body, how the immune system responds to threats, and how to observe and question health claims. The curriculum is evidence-based and avoids shame, fear, or simplistic "good vs. bad" framing.
This curriculum does not provide medical advice. It explains how biological systems work.
Who This Is For
Parents, teachers, homeschool families, school health educators, and after-school program staff. Adults who are mindful of body-image and eating-related concerns in their student population.
How to Run a 10-20 Minute Lesson
Before the session (5-10 min): Read the lesson and the Facilitator Safety Guide for any safety notes specific to that lesson.
During the session:
- Open with a body observation or "have you ever noticed?" question (1-2 min)
- Explain the main system concept (3-5 min)
- Work through the activity -- using fictional or private examples (5-10 min)
- Close with one exit prompt (1-2 min)
Recommended Session Flow
| Step | Time | What You Do |
|---|---|---|
| Opening | 1-2 min | Body observation or curious question |
| Concept | 3-5 min | How the biological system works |
| Activity | 5-10 min | Fictional examples, self-observation only |
| Close | 1-2 min | Exit prompt or reflection |
Using Fictional Examples
Many lessons involve body observations (heart rate, energy, sleep). These should always be:
- Voluntary -- students who prefer not to participate in self-measurement can observe a fictional character
- Private -- students share only what they choose to share
- Non-comparative -- do not compare measurements or patterns between students
Lessons use phrases like "Body Mystery Project" and "Clue Collector" intentionally -- keeping the framing curious and safe, not evaluative.
Adapting for Different Settings
One child at home: The Body Mystery Project (Weeks 15-18) works very well at home -- students choose their own question and observe over time. Use meal times and bedtime as natural conversation moments.
Homeschool group: The immune system and outbreak postmortem (Weeks 8-10) work well as group discussions using fictional illness stories. The capstone project can be individual or collaborative.
Classroom: Coordinate with school health staff before starting. Follow school guidelines on discussions of food, weight, and body image.
After-school program: The earlier units (Weeks 1-7) work well as standalone discussions. Avoid the Body Mystery Project in short programs where continuity is not possible.
Supporting Different Learners
Younger learners (8-9): Focus on Weeks 1-7 (homeostasis, food, energy). Avoid the optional extension weeks for younger learners.
Older learners (11-12+): The optional extensions (microbiome deep dive, stress physiology) are well-suited for older students. The Body Mystery Project goes deeper with older learners.
Students with health conditions, eating disorders, or body-image concerns: Modify or skip lessons that involve body measurement. Use the facilitator notes in each lesson for specific guidance.
Handling Sensitive Topics
Body weight and food: The curriculum explicitly avoids "good vs. bad" food labeling and weight discussion. Follow this framing carefully.
Health claims: Teach students to ask "how do we know?" and "what would change our mind?" about any health claim -- including ones they have heard from trusted adults.
Medical information: If a student discloses a health condition, acknowledge briefly and redirect to general principles. Never comment on a student's body or eating habits.
Checking Understanding
- "What is homeostasis? Can you describe it using a thermostat?"
- "What does sleep actually do for the body while we sleep?"
- "What is one question you would ask about a health claim you heard?"
Privacy and Student Data
Body measurements and observations are private. The Body Mystery Project data is kept by the student. Nothing is submitted to the website.
