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

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

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

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

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

Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

This interactive module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.

This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis.

This tutorial explores how fat is digested, transported, stored, and used for energy.

This tutorial describes the various forms of “fat” — from a tissue, to a cell type, to a class of molecules.
