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 activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.

This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.

This activity explores content presented in the animated video Solving Crimes with the Necrobiome, which describes the microbial changes associated with decomposing corpses.

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.

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 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 activity explores the content presented in the animated video How Tube Worms Survive at Hydrothermal Vents, which tells the story of the symbiotic relationship between the giant tube worm and chemosynthetic bacteria.

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

This activity analyzes a published scientific figure from a study assessing if the microbiota from a mother affects the immune systems of the developing offspring.
