In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

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.

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

In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
 

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.

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 web tool provides a quick and easy way of visualizing and analyzing data without advanced technological requirements.
