Disciplinary Core Ideas
In this unit, students study Earth’s systems, analyzing the science phenomena of natural processes that shape Earth’s surface. In this lesson, students analyze clues in Earth’s rock to determine how Earth’s surface has changed over time. This page is a high-level extract of this lesson.

In this unit, students explore science phenomena of the life forms that live on Earth, analyzing the cellular structures that make up complex organisms and figuring out how different groups of cells work together to keep the organism functioning properly. This page shows extracts from each part of this lesson.
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 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.

IIn this unit, students analyze the science phenomena of inheritance, how living things pass along their genes to offspring. Students evaluate the role of DNA and chromosomes in heredity, and compare the two forms of cell division: the phenomena mitosis and phenomena meiosis. This page shows key components of this lesson on reproduction.
In this unit, students explore the science phenomena of the interdependence of living things and their environment as they analyze how individual organisms are suited to their particular environment. In this lesson, students evaluate how Earth’s biomes have changed over geologic time, studying fossils for clues of the past.
In this unit, students explore the phenomena of diversity of life on Earth and consider how living things pass on traits to their offspring while also adapting to meet the needs of the environment. In this lesson, students figure out how scientists use the fossil record for clues to how life has evolved over time. This page highlights key parts of this lesson.
