Virtual Classroom

Bringing the St. Johns River into your classroom through our virtual learning educational programs. These videos and activities are designed to introduce the River and key scientific concepts to support your in-classroom lessons and our hands-on activities. All materials are provided to you by St. Johns Riverkeeper and will be picked up following program completion. A virtual visit into the classroom is available upon request to lead the lesson with assistance from the Teacher to ensure students stay on task and follow the protocols. Due to limited resources, virtual programming is being limited to schools in Duval ,Clay, and St. Johns County.

Watch ‘Introduction to the St. Johns River’ video on our Virtual Learning page. Two videos are available based on the age of your students.

Enviroscape (3rd-5th Grade)

Our region’s most important natural resource flows through our backyard. Let’s take a look at how the ecosystem of the St. Johns River has supported communities in the past, present, and future. Help St. Johns Riverkeeper Educator build a model of their environment and watch how pollution enters our waterways. We will discuss some of the ways we interact with our river every day and how we can protect this natural resource for future generations.


Salinity(4th-6th Grade)

What types of water do we have in our St. Johns River? We’ll find out! Using real scientific instruments (refractometers) students will measure how much salt is in a range of water samples taken from our river. They will develop and test their own hypothesis as we introduce students to vocabulary such as salinity, brackish water, freshwater, and refraction. It all comes together as we tie in the water cycle and tidal impacts as well as how salinity influences the ecology and overall health of our St. Johns River. Max 25 students per program

Watch Salinity video along with associated activities

Water Quality (6th -12th Grade)

Test the quality of the St. Johns River or one of its tributaries. Students will test several parameters including nitrates, pH, salinity and dissolved oxygen and then analyze the data to get an understanding of the water’s overall health. Discuss how human activity impacts our waterways and how we can avoid the repercussions.

Check out our water quality videos HERE to learn about each test and the river issues associated with each one. *The equipment you are provided might be different than what you see in the videos.

Rock Porosity (9th – 12th Grade)

Rocks can hold oil, natural gas, and water due to physical properties called porosity and permeability. Students will investigate the porosity of limestone, sandstone, and basalt to calculate percent porosity. This is a 24 or 48 hour lab.

Watch ‘Troubled Waters‘ to learn about our impact on the Floridan Aquifer through nutrient pollution, population growth, and over pumping.

Immerse your students into the Aquifer through Jenny Adler’s ‘Walking on Water‘ with the first 360 degree virtual tour of the Floridan Aquifer.
