Storyline Narrative 7.2.6

Standard 7.2.6: Make an argument from evidence for how the geologic time scale shows the age and history of Earth. Emphasize scientific evidence from rock strata, the fossil record, and the principles of relative dating, such as superposition, uniformitarianism and recognizing unconformities.

Student Friendly Objective: I can make an argument using evidence that the geologic time scale shows the age and history of the earth.

Anchor Phenomenon: The cliffs in Capitol Reef National Park have observable layers (see image on unpacked document).

Big Idea:  Layers of rock provide evidence of Earth’s history.

 

Students are engaged by working their way through stations that teach them aspects of geology that help scientists determine the age and history of the Earth (episode 1). They are introduced to the law of superposition and explore how the rock layers and fossil record could be evidence of the past.

Students investigate the geological history of Utah and explain how the fossil and rock layer evidence supports the story of Utah’s changing landscape (episode 2). Creating a timeline elaborates how layers of rock provide evidence of Earth’s history.

Students are evaluated as they make an argument from evidence to explain the location and age of fossils in a particular mountain side.

You found the secret message! Huzzah!

Episode 1

Question

What do the layers in a cliff face tell us?

Snapshot

Students work through stations to discover how layers of rock provide evidence of Earth’s history.

Conceptual Understandings

The layers in a cliff face tell us information about the age and history of the earth.

What evidence do we have of Utah’s geologic past?

 

Conceptual Understandings

Utah’s environment and geology have changed over time, as shown by the evidence provided by the fossil record and rock layers.  

Snapshot

Students prepare a timeline of Utah and observe the changing geological landscape that is supported by fossil and rock layer evidence.

Episode 2

Question

What evidence do we have of Utah’s geologic past?
