Fossil evidence and biological evolution take center stage in this Grade 6 science learning stations activity. Students investigate fossil patterns in rock layers to trace changes in organisms through geologic time and use evidence to reason about evolutionary relationships, diversification, extinction, and biodiversity.

Rather than treating fossils as isolated discoveries, students consider how fossil ages, anatomical similarities, and geographic distributions provide clues about the history of life. The station-based format gives students a structured way to examine evidence, record observations, and compare findings across different cases.

Investigating Fossil Evidence

Students work with fossil-related case-study cards and a recording sheet to explore patterns that reveal biological change over time. They focus on interpreting evidence rather than simply recalling definitions, connecting what fossils show to broader questions about how organisms have changed and how biodiversity has shifted throughout Earth's history.

• Analyze fossil patterns in rock layers to identify changes in organisms through geologic time.
• Use fossil ages and anatomical similarities to infer relationships between organisms.
• Consider geographic distributions when interpreting evidence of evolutionary change.
• Compare fossil assemblages to explain diversification, extinction, and changes in biodiversity.

What Is Included?

• Station cards: Case-study materials for students to examine and discuss fossil evidence.
• Station recording sheet: A place for students to document key information as they visit each station.
• Station wrap-up: A concluding activity that brings the investigation together.
• Answer Key PDF with Teacher Guide: Includes learning objectives, teaching tips, discussion questions, and common mistakes to help guide instruction.

How to Use the Activity

Place the station cards around the classroom and divide students into small groups. Groups begin at different stations, examine the case-study information, and record their findings on their own recording sheets. After a set time, students rotate to the next station until they have visited them all. Finish with a class discussion in which groups compare their evidence and explain how fossil patterns support conclusions about evolutionary change.

This format works for a dedicated science lesson, a collaborative evidence-analysis activity, or a review of biological evolution. The recording sheet keeps students focused on documenting evidence, while the wrap-up provides an opportunity to connect observations from different stations.

NGSS Connection

This resource is identified with NGSS MS-LS4-1, which focuses on analyzing and interpreting data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth. The activity's emphasis on fossil patterns, geologic time, and biodiversity provides a context for discussing this middle school life science topic.

For Grade 6 science teachers covering biological evolution, this resource combines structured group work, evidence-based reasoning, and teacher support in one station-based lesson.
