SRA Floating Classroom


You’re invited to experience a hands-on environmental and scientific adventure
on the Severn River

SRA’s  Floating Classroom, where “class” is held aboard our 20-ft. Maritime Skiff, The Sea Girl. The Classroom program provides science-based experiences to enhance our appreciation of the Scenic Severn River. During this 3- hour tour, students get a chance to learn about conditions in the water as they use water quality monitoring equipment to check on oxygen levels, pH, temperature, salinity and clarity. They will also sample, identify, and map our underwater grasses, check on our oysters, and review other habitat for the creatures that share the river with us.

The Floating Classroom is possible thanks to grants from BGE Green Grants and CB Trust.

This is a fun program for students of all ages

To the right, four 7th graders enjoyed the boat ride, studying oysters and identifying underwater grasses.

Below, four rising seniors at Indian Creek School joined us for a Floating Classroom.

Using guidebooks and an SAV Watchers datasheet, the team identifies the SAV that thrives at different locations in the Severn. Students also learn how to prepare a sample of the submerged aquatic vegetation for proper identification.


Schedule Your Adventure!

We are now scheduling Floating Classroom adventures for small groups, up to 4 guests, in Sea Girl. Our classes set sail on Mondays and Tuesdays, at 10 a.m. or 1 p.m. weather permitting.

Info: Please email:

This is hands-on citizen science that helps us all better appreciate and treasure the Severn River! The tours last about 3 hours.

The 20-ft classroom affords room for social distancing while students learn first-hand how to:

  • take a clarity reading with a Secchi Disk,
  • measure oxygen, pH, temperature, salinity and clarity,
  • contribute to expanding our understanding of the Severn River,
  • identify species of underwater grasses, and
  • see what a restored reef looks like on the bottom of the river on a sonar-based fishfinder screen.

Everyone’s invited to join in the scientific and educational adventure aboard our “classroom,” Sea Girl.

SRA’s invitation to climb aboard Sea Girl for the Floating Classroom goes out to students, friends, children, Boy Scouts, Sea Scouts, Girl Scouts and adults (yes, they’re students too!).
