Meet Mateo
Observe first, then write a testable question.
Each lesson begins with an illustrated analogy, asks you to build the rule, transfers that rule to real biology, and ends with a concrete decision. The answer becomes the next lesson's starting point.
Everything required is on this page. Outside research is optional. CF-001 is a composite teaching case and is not a real patient record or diagnosis.
Read the case, then use the explainer and glossary whenever a term is new.
Observations, timeline, evidence cards, claim ceilings, figures, and the final case board.
One short ninth-grade reading per lesson, plain-English definitions, illustrations, and optional links for more.
Every deck has the analogy visual, Socratic questions, a biology illustration, a real mechanism, and a decision.
Observe first, then write a testable question.
Tissues grow, move, meet, and join on a schedule.
A cleft names the result, not one single cause.
Neural crest cells travel to the facial build site.
Internal state and outside cues guide cell fate.
Contact is followed by active seam remodeling.
DNA becomes RNA, protein, and context-specific cell behavior.
The lesson-plan guide explains each move, why it happens in that order, and what students produce. The red-team audit maps every task to the evidence supplied inside the unit.
Observe. Question. Test. Revise. Go Hornets.
