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.
In this unit, students figure out connections between genes and heredity to evolution, focusing on figuring out the phenomena of how both genetic information and the environment influence how a population develops over time. Students investigate different kinds of evidence for life’s shared ancestry and then experiment with how adaptations help some organisms survive. Students end with an investigation into artificial selection.

In this unit, students focus on the phenomena of Earth’s ice as they model how glaciers shape Earth’s surface. In this lesson, they investigate how scientists use ice cores to reconstruct Earth’s past climates and environments. This page is a high-level extract of this lesson.

In this unit, students focus on phenomena related to Earth’s ice as they model how glaciers shape Earth’s surface, and investigate how scientists use ice cores to reconstruct Earth’s past climates and environments. In this lesson, students analyze how scientists can use the science phenomena of fossils in rock layers as evidence for past changes on Earth. This page showcases all the components of this lesson.
In this unit, students explore phenomena that change Earth’s surface over time, analyzing how weathering, erosion, and convection in the mantle are three phenomena that help to cycle Earth materials. In this final lesson of the unit, students use their knowledge to analyze the science phenomena of rock strata, thus reconstructing Earth’s geologic history. This page showcases components of this lesson.
