Grades K–2
Overview
People—like all living beings—rely on the natural world in order
to survive. The water and electricity we use in our homes and
schools, for example, can be traced back to nature. By exploring
why we need water and electricity, and by investigating where these
resources come from, students begin to understand the importance
of keeping water clean and learn how to help save water and reduce
demand for electricity.
