Purpose
Students investigate what fossil evidence reveals about feathers, scales, and the evolutionary link between dinosaurs and birds. Teams analyze fossil patterns and locations, connect their distribution to past plate motions, and compare evidence and interpretations from documentaries and credible articles. Students use respectful peer critique to revise a claim-evidence-reasoning poster that addresses whether some dinosaurs had feathers and acknowledges counterarguments. Research reflections and a partner discussion help students track how their scientific thinking, questions, and collaboration changed.
Learning goals
Students will analyze fossil evidence, scientific observations, and research notes to identify patterns showing that some dinosaurs had feathers and explaining their relationship to modern birds. They will interpret fossil distribution and continental data to consider how past plate motions influenced where dinosaur fossils are found. Students will compare competing claims, cite reliable evidence, respectfully exchange critiques, and revise their explanations in response to questions and feedback. They will create a claim-evidence-reasoning poster and reflect on how new evidence changed their thinking and raised further questions.
Products
Students will create research notes that compare documentary and article evidence about dinosaur feathers, scales, fossils, and links to modern birds. Teams will develop an evidence map showing fossil locations and use past plate motions to interpret distribution patterns. Each student will record post-research insights and questions, then join a partner reflection and evidence-based critique to identify revisions. The final product will be a revised claim-evidence-reasoning poster and brief presentation answering whether some dinosaurs had feathers, including competing interpretations, cited sources, and a reflection on how the student’s thinking changed.
Launch
Begin with an evidence mystery: teams examine fossil photographs, feather and scale impressions, dinosaur-bird anatomy comparisons, and maps showing where fossils were found. Students compare scaly and feathered dinosaur reconstructions, then cite observations as they debate, “What evidence shows that some dinosaurs had feathers, and how does this change what we know about birds?” Teams respectfully critique competing claims, ask clarifying questions, and identify evidence they would need before reaching a conclusion. Students end with a partner reflection and write or record one insight, one remaining question, and an initial claim to revisit in their final claim-evidence-reasoning poster.
Exhibition
Host a gallery-style “Feathered Dinosaur Evidence Expo” for classmates, families, and school staff. Teams present claim-evidence-reasoning posters using fossil observations, source comparisons, fossil-location and plate-motion data, and evidence linking dinosaurs to birds. Visitors compare competing explanations and leave respectful, evidence-based questions and feedback, which teams use to make final revisions. Students conclude with a partner reflection about how their thinking changed, one new insight, and one question they still want to investigate.
