Unit 01 · Body Systems & Wellness Basics
Study the major body systems and how they work together. Interpret baseline measurements as evidence about function, not appearance. Use a fictional or de-identified dataset, an approved measurement model, or an optional personal record kept private. Personal health disclosure is never required for the grade.
| Criterion | Developing | Proficient | Mastery |
|---|---|---|---|
| Major body systems & their functions | Confuses the major body systems or cannot say what any one of them does. | Names the systems but stumbles explaining the job each one performs. | Names the circulatory, respiratory, digestive, nervous, musculoskeletal, and immune systems and explains the core function of each. |
| How the systems work together | Treats each body system as if it worked alone. | Knows the systems connect but cannot trace how one depends on another. | Traces how systems cooperate — e.g. how the respiratory and circulatory systems together deliver oxygen to working muscles. |
| Reading baseline data | Cannot interpret the supplied baseline measurement. | Reads the number but treats it as a verdict rather than evidence. | Interprets a baseline using an approved dataset or measurement model, stating its limits without judging appearance or health status. |
| Wellness as a whole-person baseline | Thinks wellness means only one thing, like just being fit. | Lists a few parts of wellness but cannot connect them into a whole-person picture. | Describes wellness as a whole-person baseline — physical, mental, and social — and explains why no single measure captures it. |
| Anchor lab (body-systems & wellness analysis) | Records no evidence from the approved task. | Records values but cannot connect them to body systems. | Records the approved data source or measurement method and explains how the systems cooperate, without requiring a personal health disclosure. |
| Integration (cross-domain) | Makes no supported connection between the source and the science. | Uses the source but needs help connecting evidence, writing, or limitations to the science. | Independently connects History, Reading, and Writing using a cited source, appropriate evidence, a limitation, and a scientific explanation. |
Integration is reported separately and cannot lower the science grade or block a science demonstration pass. Science and practical criteria determine that pass. Use the integration guide's evidence checklist for the separately reported criterion.
“My resting heart rate is a baseline — a starting number about how my heart works, not a score about my body. And breathing and circulation are a team: my lungs load the oxygen, my blood carries it to my muscles. That’s a system I can trace, not a fact I memorized.”
“The heart… pumps blood? And wellness is like being healthy, I guess — I’m not sure how the parts fit together.”
Use an approved data or measurement task and explain the body-systems science. A supplied fictional dataset or measurement model is a valid alternative to personal records, without a grade penalty or token charge. Assess the evidence and reasoning, not the learner's body or willingness to disclose health information.
