# The Power Function

Scaling studies examine how form and function change as organisms get larger -
in other words, how do biological features *scale* across size? Do they
change in meaningful ways as organisms get bigger or smaller? Of course, you
can't even ask these types of questions without having a way of measuring how
relationships change mathematically. So, our main goal in this section is to
introduce you to the idea of scaling studies - and also the mathematical function
used to measure them: the power function!
