A simple activity that investigates the importance of antifreeze proteins to icefish survival.
A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.
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.
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.
Students interpret the results of two different tests for lactase persistence.
Students explore the genetic changes associated with lactose tolerance/intolerance and how the trait is inherited in families.
Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film.
In this lab, students test different samples to see which ones contain the lactase enzyme.
Students explore the effects of different diets on the evolution of an enzyme that breaks down starch.
