Students will investigate competing interpretations of dinosaur appearance through a fossil-evidence mystery, form and revise an initial claim, and identify evidence needed for their final claim-evidence-reasoning poster.

Students will investigate fossil, anatomical, geographic, article, and documentary evidence before drafting and revising an evidence-based explanation about feathered dinosaurs and their relationship to modern birds.

Students will publicly defend and refine evidence-based conclusions about feathered dinosaurs, fossil distribution, and dinosaur–bird relationships through a final exhibition and reflection.
