FOSS Earth History Inv 6 - It's About Time (5days)
Big Idea
Students become familiar with the geological time scale, begin to comprehend the enormous spans of time that are described by geological time and put the history of the Grand Canyon into the scale
Essential Questions
How can spans of time be divided?
Why do we have more information about the more recent times in Earth's history?
What information is displayed on a geologic time line?
How do the Grand Canyon rock fit into geologic time?

Formulate questions based on observations that lead to the development of a hypothesis.
Propose possible solutions to address the environmental risks in biological or geological systems.
Describe how the rock and fossil record show that environmental conditions have changed over geologic and recent time.
Analyze environmental risks (e.g., pollution, destruction of habitat) caused by human interaction with biological or geological systems.
Explain the following processes involved in the formation of the Earth's structure
  • erosion
  • deposition
  • plate tectonics
  • volcanism
Analyze the evidence that lithospheric plate movements occur.
Create a personal time line from birth to the present
Create a personal time line.
Creating a class geologic time to scale.
Science & Engineering Practices
Developing and Using Models: students create several versions of time-lines
Content/Core Ideas
  • Geological time extends from Earth's origin to the beginning of human history.
  • The geological time scale is an arbitrary arrangement of geological events, most often presented as a chart.
  • Earth's history is measured in millions of years.
Crosscutting Concepts
  • Scale, Proportion, and Quantity
  • Stability and Change
