Construct an explanation of how genetic variations occur in offspring through the inheritance of traits or through mutations.
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 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 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.
