Support or refute an explanation by arguing from evidence for how the body is a system of interacting subsystems composed of groups of cells.
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.
