Reduce, Reuse, Recycle

By examining trash, students can learn a lot about how and why they throw things away. Students find ways to reduce their community’s waste production and improve its management through participation in a service-learning project.

Global Goods

Students gain an appreciation for how many natural resources they depend on in their day-to-day lives. By tracing the resources that go into making one item, students learn how its manufacturing can have an impact on the environment.

Water Wonders

The water cycle is the system by which Earth’s water is collected, purified, and distributed from the environment to living things and then returned to the environment.
