Objectives

MS-ESS1-4. (Chapter 3) - Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth's 4.6 billion-year-old history.

MS-LS4-1. (Chapter 2) - Analyze and interpret 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 under the assumption that natural laws operate today as in the past.

• Explain how Earth materials, such as rock, fossils, and ice, show that Earth has changed over time.

• Summarize how scientists measure the relative ages of rock layers.

• Identify gaps in the rock record.

• Describe how geologists use a geologic time scale to divide Earth's history.
