These activities are designed to explore ocean acidifcation in the middle school classroom. As oceans absorb atmospheric CO2, they undergo a series of reactions that cause a reduction in normally stable ocean pH.

South Florida is home to some of the world’s most unique aquatic ecosystems such as the Everglades, which provide critical ecosystem services for the people and animals of South Florida. Take off with Philippe Cousteau and EarthEcho Expeditions co-host Josh Carrera, as they explore how Florida’s Everglades are being protected and restored after decades of damage from development and agricultural runoff. Our hosts travel by helicopter and airboat to examine how natural ecosystems can be engineered and adapted to mitigate agricultural pollution.

Looking out on the Big Meadow in Shenandoah National Park, it’s not hard to understand what drew Sally Hurlbert to her job here and also what has kept her here for a number of years. Sally is a Park Ranger in Shenandoah National Park, a job that allows her to combine her deep love of the natural world with a talent for sharing her knowledge with others. Her work as an outdoor educator allows Sally to teach people about the natural resources of the park. This allows her to explore many different disciplines of science like wildlife biology, botany, aquatic biology and chemistry, and geology.

Kevin Lutz is an Agriculture Conservation Technician and Assistant Agriculture Program Manager with the Lancaster County Conservation District. This scientist works with farmers to protect their land and the associated local waterways. He can be found doing everything from checking the construction of a manure storage facility on a dairy farm to walking fields and developing a conservation plan on a hog farm to comparing water quality reading in local streams. Sometimes he can even be found selling trees at the Conservation District’s annual tree sale! The variety in his job keeps it exciting, while the end result keeps it rewarding.

For Dr. Beth McGee, a Senior Water Quality Scientist at the Chesapeake Bay Foundation, science is all about passion and the outdoors. Dr. McGee has always loved running through streams, catching fish and tadpoles, and hiking in the woods, so her job as a scientist is an extension of that. She is captivated by figuring out how things in nature “work.” She says, “Whether it is how animals adapt to their environment or how temperature affects ecosystem processes. I find it all fascinating.”
