This article describes a second grade science enrichment unit with a focus on human impact, both positive and negative, on the living and nonliving components of the local watershed. Investigating the local watershed gave the unit a personal and pragmatic connection to students' lives because they depend on the local watershed for what they need to live and grow. By investigating creatures living in the watershed and how they are affected by positive and negative habitat impacts, students realized that they can make a difference by making simple choices. Additionally, students realized that their decisions affect their lives because they are members of the local watershed as well.
