Easy test(?) for living organisms

For a museum laboratory exercise is there an easy test for living
organisms? For example, if given a sample of soil what test can I have
visitors perform to determine if there is anything living in it? This
would be a possible modeling of a probe to Mars for example to look for
living organisms.

Must be SAFE, easy to interpret ie color reaction, and not take more
than several steps.
