This video follows an international team of researchers as they collect data to map migratory bird populations in the US and Mexico.

In this activity, students use an interactive tool to simulate how scientists collected and used sample data to estimate elephant population sizes.

This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This interactive video explores how two scientists tracked the 2013 Ebola outbreak in West Africa. 

In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

This interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

This Click & Learn shows that keystone species exist across a variety of ecosystems and can exert their influence in different ways.

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

This animation shows how glycolysis converts glucose into pyruvate through a series of enzyme reactions. It is the first of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.

This animation shows two examples of how the cell uses energy from ATP. It is the sixth of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.

This animation shows how the pyruvate dehydrogenase enzyme complex converts pyruvate into acetyl-CoA. It is the second of six animations about cellular respiration.

This video shows how a group of students, scientists, and volunteers came together to make hand sanitizer and masks for their community during the COVID-19 pandemic.
