In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.
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.
In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.
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 activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.
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 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 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.
