In this chapter students explore the concept of habitability.
They define the requirements for a habitable place, then explore
Earth and other worlds in our solar system looking for places
that potentially support life. They also conduct experiments
to see that the ability of life to exist under extreme
conditions greatly expands the possibility that we may find
life on other worlds in our solar system.
In Is the Moon Habitable, students study the
Earth and moon to see that they occupy the same general location
in the solar system, yet are vastly different in their habitability
for life.
They examine how the presence or absence
of key habitability factors and physical conditions affect
life and understand that, ultimately, life must yield to some
physical limits.
