Fossil Forensics: Unraveling Mysteries of Past Ecosystems
Inquiry Framework
Question Framework
Driving Question
The overarching question that guides the entire project.How can we use fossils as clues to reconstruct and interpret the story of Earth's changing environments and the life they supported?Essential Questions
Supporting questions that break down major concepts.- How do fossils provide a window into Earth's past?
- What can fossil evidence tell us about environmental changes and their impact on ecosystems?
- In what ways do fossils help us understand evolution and extinction?
- How can we use fossil records to reconstruct ancient life and environments?
Standards & Learning Goals
Learning Goals
By the end of this project, students will be able to:- Analyze fossil records to understand past life forms and ecosystems.
- Model the processes of fossil formation and relate them to geological timescales.
- Explain how environmental changes, as evidenced by fossils, influence evolution and extinction.
- Communicate findings on ancient ecosystems through presentations or exhibits.
Entry Events
Events that will be used to introduce the project to studentsMystery Fossil Auction
Students attend a mock auction where they bid on unidentified fossil specimens. Each fossil comes with limited background information, sparking initial questions about its origin, the environment it lived in, and its place in the fossil record. This event promotes curiosity and sets the stage for in-depth investigation throughout the project.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.Ancient Ecosystem Reconstruction
Students analyze a collection of fossils from a specific geological period and location to reconstruct the ancient ecosystem. They will identify the organisms, infer their relationships, and describe the environment in which they lived.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA visual representation of an ancient ecosystem with detailed descriptions of the organisms, their relationships, and the environment.Alignment
How this activity aligns with the learning objectives & standardsAddresses the learning goal of analyzing fossil records to understand past life forms and ecosystems.Environmental Change and Extinction Timeline
Students investigate how environmental changes, as evidenced by fossils, have influenced evolution and extinction events throughout Earth's history. They will create a timeline highlighting major environmental shifts and their impact on life.Steps
