SummaryA simple activity that investigates the importance of antifreeze proteins to icefish survival.
Appropriate for: middle school life science, high school biology (all levels)
This activity serves as an extension to the Howard Hughes Medical Institute short film The Making of the Fittest: The Birth and Death of Genes. It is meant to reinforce the concepts of adaptation and the birth of new genes. Students perform a wet lab using simple materials that help them understand the “antifreeze” adaptation described in the film.
