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 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.

This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

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

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.

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 allows students to compare the morphological characteristics of seashells and construct an evolutionary tree.
