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

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 explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

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 explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

Several questions are embedded within the short film The Making of the Fittest: Natural Selection and Adaptation, which uses the rock pocket mouse as a living example of natural selection.

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 module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.

This tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.

This interactive, modular lab explores the techniques used to identify different types of bacteria based on their DNA sequences.

This playlist can be used in an online, undergraduate (majors-level) introductory biology lab to incorporate core topics in evolution, diversity of life, and ecology.
