  • How Novel Icefish Genes Can Improve Human Health

    How Novel Icefish Genes Can Improve Human Health

    Activity

    A lesson that requires students to read detailed scientific passages and explain how an understanding of specific icefish adaptations might lead to a treatment or cure for human disorders, such as osteoporosis and anemia. 

  • Ice Crystal Formation in Icefish and Non-Icefish Blood

    Ice Crystal Formation in Icefish and Non-Icefish Blood

    Activity

    A dramatic demonstration that simulates how tiny ice crystals would form and grow in the blood of most fish if they ventured into the icy waters of the Antarctic.

  • Demonstration: Viscosity of Icefish and Non-Icefish Blood

    Demonstration: Viscosity of Icefish and Non-Icefish Blood

    Activity

    A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.

  • Icefish Adaptations

    Icefish Adaptations

    Activity

    A simple activity that investigates the importance of antifreeze proteins to icefish survival.

  • Film Guides: The Birth and Death of Genes

    Film Guides: The Birth and Death of Genes

    Film Guide

    The following classroom-ready resources complement The Making of the Fittest: The Birth and Death of Genes, which describes how scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
