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

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

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

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

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

A number of questions are embedded within the short film The Origin of Species: The Beak of the Finch, which explores four decades of research on the evolution of the Galápagos finches.

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

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

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 interactive module explores the different gaits employed by animals and how the nervous system is able to switch between gaits.
