This feature film describes how the genetic legacy of early primates can be seen today in our own DNA.
Students examine the ethical issues raised by three situations in which prenatal testing may be used to prevent or facilitate pregnancy.
Students explore the phases, checkpoints, and protein regulators of the cell cycle and find out how mutated versions of these proteins can lead to the development of cancer in this interactive resource.

In this activity, students examine how natural selection works to bring about the evolution of adaptations. Using a simulation tool, students can slow down the process to examine all the steps involved, or speed it up to observe how a population evolves over time.
In this activity, students learn why evolution is at the heart of a world health threat. They will investigate the increasing problem of antibiotic resistance in such menacing diseases as tuberculosis and influenza. Students take on the role of staff at a public health agency who are trying to communicate the widespread problem of evolving disease-causing agents to the public.
This interactive illustrates how a changing environment (represented by different background colors) can prompt the evolution of a population of virtual creatures.
These two activities support the film The Origin of Species: The Beak of the Finch. They provide students with the opportunity to analyze data collected by Princeton University evolutionary biologists Peter and Rosemary Grant.

This news brief from October 2010 examines new research that makes it clear that Tibetan highlanders have not just acclimated to their mountain home; evolutionary adaptations have equipped them with unique physiological mechanisms for dealing with low oxygen levels.
This interactive explores different anatomical features of the human body and what they reveal about the evolutionary history humans share with other organisms, including earlier, long-extinct species.
This task could be used as part of photosynthesis instruction or as an assignment before photosynthesis is taught. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.
This lesson is based on the highly engaging book Feathers: The Evolution of a Natural Miracle by Thor Hanson. Alternate texts and strategies for sharing are provided in case there are not enough book resources for all students to have an individual copy. As they read, students will take notes and then participate in an interactive "grab bag book review" where they will take objects from a bag, one at a time, to act as prompts for re-telling big ideas from the book and lesson.
This news brief from December 2009 focuses on malaria. Malaria is normally treatable, but now some strains are evolving resistance to our most effective drug. Students will find out how researchers and doctors are trying to control the evolution of the disease.
These classroom-ready resources complement the film "Great Transitions: The Origin of Humans," which reveals the history of our evolutionary origins.
In this activity, students use a pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.
In this lesson, part of the NC Science Now series, students will identify the factors that affect the Red Drum population and discuss the relationships between predator and prey.
Students will be able to explain developmental and migration patterns of salmon and apply that understand- ing to other migratory species.
This brief video describes the five ways that evolutionary change can occur. Assessments for the student to complete after viewing the video are also included.
Flowering plants keep the world cooler and wetter than it would be otherwise.
