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 activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

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.

This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.

This activity instructs students how to build their own Winogradsky columns, which provide visual examples of the diverse modes of metabolism in the microbial world.

In these activities, students transcribe and translate portions of the rock pocket mouse Mc1r gene to further explore the genetic variations responsible for different coat colors as described in the short film Making of the Fittest: Natural Selection and Adaptation.

This activity supports concepts presented in the short film Natural Selection and Adaptation about the evolution of different fur colors among rock pocket mouse populations.

This activity supports concepts covered in the film Natural Selection and Adaptation. Students analyze genetic sequence data and draw conclusions about the evolution of coat-color phenotypes in the rock pocket mouse.

This activity explores the research presented in the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have allowed some fish to adapt to extreme environments.
