| Within a population,
some individuals die very young while others live into old age.
To a large extent, the pattern
of survivorship is species-dependent.
Generally, three patterns of survivorship have been identified.
These three have been summarized by survivorship
curves, graphs that indicate the pattern of mortality (death) in a
population.

In this
exercise, students studied populations of dice and soap bubbles,
using them as models of real populations to construct survivorship curves.
The students then subjected these populations to different kinds of
stress in order to determine the effects upon survivorship curves.
