In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment. 

This interactive module allows students to examine fossils of early humans and compare them to modern primates.

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

This model shows the skull of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).

This model shows the skeleton of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).

This model shows the pectoral fin bones of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).

This model shows the pelvis of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).

This model shows the humerus bone of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).

This activity guides the analysis of a published scientific figure from a study that used footprints formed millions of years ago to estimate the heights of early human ancestors.

This activity explores the content presented in the animated video How Tube Worms Survive at Hydrothermal Vents, which tells the story of the symbiotic relationship between the giant tube worm and chemosynthetic bacteria.

This asynchronous course is designed to deepen educators' content knowledge in evolution, especially regarding content appropriate for teaching at the high school level. 

In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.
