6.3 Why Do Organisms Look the Way they Do?
This module focuses on heredity, and how traits pass from one generation to the next in both plants and animals, including humans. The organizing theme is comparing organisms; students investigate what makes them similar or different, and develop a model of inheritance to help them understand heredity. They then use the model of inheritance to explain and predict phenomena. Given that organisms need to reproduce in order to pass on their traits, the module also explores structures and behaviors of some organisms that enable them to reproduce. This module builds foundational knowledge and explores underlying mechanisms for inherited traits that is built on when investigating populations and change over time in 8th grade.
