Construct and use models to explain that genetic variations between parent and offspring occur as a result of genetic differences in randomly inherited genes located on chromosomes and that additional variations may arise from alteration of genetic information.
In this unit, students investigate phenomena related to how organisms pass on traits to their offspring. Students begin, in this lesson, with an investigation into how DNA codes for proteins, which determine an organism’s traits. This page provides a high level overview of this lesson.
In this unit, students figure out the interconnectedness of genetics, heredity, and evolution. For this lesson, students create an experiment to observe the phenomenon of natural selection determining which organisms are most likely to survive and pass on their traits. This page showcases parts of key components of the lesson.
In this unit, students apply what they know about genes and heredity to evolution, focusing on how both genetic information and the environment influence the phenomena of how a population develops over time. In this lesson, students explore the phenomena of how adaptations help some organisms survive. Students also investigate artificial selection. This page showcases key parts 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.
