Texas Watch is an environmental stewardship-in-action program that works with the Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality to collect environmental data and to address nonpoint source pollution issues. Volunteers across the state monitor rivers, creeks, ponds, lakes, bays, bayous, and estuaries. The information helps local and state resource managers make scientifically sound decisions. This article describes how participation in this inquiry-based project promoted environmental awareness in seventh- and eighth-grade students while engaging them in meaningful, scientific research.
