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 compare the science phenomena of bacterial, plant, and animal cells, figuring out similarities among them all as well as differences. Students then conduct an experiment into how yeast cells extract energy from food molecules. This page highlights components of this lesson.
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 discover how life reproduces at the cellular level, analyzing the science phenomena of how genetic information is stored in chromosomes. In this lesson, students observe mitosis in plants and animals. This page shows key components of this lesson.
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.
In this unit, students focus on science phenomena related to the diversity of life, analyzing how scientists use the fossil record to tell of how life has evolved over time. In this lesson, students then compare the phenomena of cellular diversity in fungi, plant, and animal cells, exploring how similarities can be used to support evolutionary relationships. This page is a high-level extract 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 explore the structure and function of the human body by developing models of the interactions within and between systems. In this lesson, they investigate the science phenomena of cellular hierarchy in multicellular organisms, including major organ systems and their functions.
