In this card activity, students investigate the functions of major digestive organs.

This film explores the evolutionary connection between an infectious disease, malaria, and a genetic condition, sickle cell disease.

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

This highly customizable activity guides students through organizing and documenting spreadsheet data during a class investigation.

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

In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

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

This activity guides the analysis of a published scientific figure from a study that investigated how human populations might adapt to milk consumption, both genetically and culturally. 

This activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.

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.
