Grades 3–5
Overview
For people who live in a city such
as San Francisco, it can seem that
nearly everything we need comes
from the work and ingenuity of
people. But we would not be able
to survive without the natural
systems that support and sustain
us. By examining the sources of
their water and power, and seeing
where wastewater goes after it is
used, students come to recognize
the ways that people both depend
on and impact the environment.
They identify actions they can
take to protect precious natural
resources.
