is
designed
to
introduce
children
to
the
Earth's
atmosphere
and
its
importance
to
life
on
Earth.
It
also
introduces
how
the
addition
of
new
gases
(e.g.,
ozone)
contributes
to
changing
the
quality
of
air
we
breathe.
With
an
understanding
of
how
our
atmosphere
works,
we
can
begin
to
understand
how
our
activities
may
be
contributing
to
some
of
those
