This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).
The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.
This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.
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 activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.
This activity complements the animated short video Seeing the Invisible. Students explore concepts related to relative size and scale using cards of cells and microorganisms.
This activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.
This multipart activity is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world.
