Construct an explanation using evidence to explain how body systems have various levels of organization. Emphasize that cells form tissues, tissues form organs, and organs form systems specialized for particular body functions.
In this unit, students explore science phenomena related to life forms that live on Earth, analyzing the cellular structures that make up complex organisms and how different groups of cells work together to keep the organism functioning properly. In this lesson, students test the effect of sucrose concentration on the heart rate of daphnia, observing how different organ systems work together. This page provides a high-level extract of this lesson.
In this unit, students continue their exploration of the cell with a focus on the phenomenon of DNA. Students use models to compare and contrast asexual and sexual reproduction and to investigate how traits are passed down from parents to offspring. This page is a high-level extract 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 the relationship between an organism’s cellular structure and the ability of the organism to access energy to carry out essential life functions. Students begin by examining prokaryotic and eukaryotic cells under the microscope and then compare organelles in plant and animal cells in this lesson.

In this unit, students explore the organisms that live on Earth’s surface, analyzing how living things are made of cells, which have certain requirements for survival, including food, water, and energy. In this lesson, students figure out the phenomena of energy transfer in living systems with a focus on how energy and matter flow through organisms. This page showcases excerpts from components of this lesson.
In this unit, students focus on the structure and function of specialized cells, tissues, and organs in the phenomena of complex multicellular organisms, and they explore how the body processes information gathered by sensory receptors. In this lesson, they develop a model for a human organ system and then observe different human cells to understand how structure influences function. This page highlights each part of this lesson.
In this unit, students discover the structure and function of specialized cells, tissues, and organs in complex multicellular organisms, and they explore the phenomena of how the body processes information gathered by sensory receptors. This page is a high-level lesson extract.
