This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

This four-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

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 explores how CRISPR-Cas9 technology works and the many ways in which scientists are using it in their research.

This short video explores the stages of decomposition of animal bodies and shows how microorganisms found during the decomposition process can provide useful information for criminal investigators.

This short video explores a thought experiment of what the world would be like without any microbes.

This short video explores the symbiotic relationship between the Hawaiian bobtail squid and light-producing bacteria.

This short video explores the secrets behind termites’ power to digest an abundant source of food: wood.

This short video explores the symbiotic relationship between giant tube worms and species of chemosynthetic bacteria.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.
