River Explorer Program

River Explorer is an innovative, inquiry based, outdoor learning-lab that provides experiential, activity-based environmental focused STEM education about the Ohio River and its watershed, in Ohio, Indiana, and Kentucky. More than 45,000 students have participated in River Explorer since the program began in 2005.

River Explorer is offered in Greater Cincinnati and Greater Columbus, OH to GRADES 4 thru 12.

Using nets, live specimens, and field grade equipment, students are junior scientists for the day and are introduced to a new and exciting learning experience. This hands-on education program is designed to help children learn about the ecology and importance of the Ohio River, its tributaries, and watershed. Classes are taught in and along the rivers, streams, and creeks in the watershed; in Ohio, Indiana, and Kentucky.  Every year thousands of students are River Explorers!


Learning station activities connect the concept of watersheds to school STEM core content, teach students about Ohio River watershed ecology, and involve students in water quality and ecology projects to foster development of environmental stewardship ethics. During the activities students learn about the differences, structures, and interactions between and in aquatic and terrestrial ecosystems and how they function in a watershed. The experience is guaranteed to make students look at the world in a new light!

To help students more fully understand the relationships between Chemistry, Macroinvertebrate, and Fish samplings and their related findings, we use Habitat Assessment tools for student classes grades 6-12.   

River Explorer learning stations are currently designed for 4th thru 12th grade students and meet state curriculum requirements for Ohio, Kentucky, and Indiana. Activities incorporate discussions of the relationship between food web, habitat, and chemistry concepts.

Classes rotate through three learning stations where they engage in these different activities. Below you will find more information about each station.

Stations One and Two - All Grades

Seining and Fish Study - Working in small teams, students will get an opportunity to help pull the seine net out of the river and retrieve whatever they've caught in the net. Depending upon height of student and site location, a student may get wet up to their knees or waist. Fish adaptations are examined first hand using aquariums stocked with "the catch of the day" collected by the children during the seining activity.

Aquatic Macroinvertebrate Study - Gathering macroinvertebrates opens up whole new topics for exploration

Third station - Grade Specific Learning Activity

The following station we offer to customize your program and better fit your individual curriculum needs.

River Chemistry (grades 6-12): We found some dead fish and we need a top notch investigative team to figure out why! Our prime suspect is the water. Students will test samples of river water for oxygen, temperature, and more. Students learn why these parameters are so important to river health and fish longevity and vitality.

Water Use and Water Cycle (grades 4-5): Through interactive demonstrations and group activities (i.e. bucket brigade), students learn what is the Ohio River hydrologic cycle and learn about what impact human activities have on the health of the river.
