In this activity, students collect and analyze data from a hands-on model to discover why even slight variations in beak size can impact a bird’s ability to obtain food and survive.
In this activity, students simulate a lactose tolerance test, similar to the one shown in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, to determine which samples contain the lactase enzyme.
