The South Dakota Discovery Center is issuing a call for water transparency data from lakes, streams, rivers, ponds in South Dakota using a turbidity (or transparency) tube,  often referred to as a t-tube since both transparency and turbidity start with the letter t.   The t-tube is a simple instrument. It is a tall, transparent tube of at least 120 centimeters that is marked off in centimeters on the side. On the bottom is a quadrant pattern of alternating black and white sections. You can measure the clarity of the water by measuring the depth of the water in the...

Every year, I offer a field based professional learning opportunity (PLO) for educators. This year's PLO was Exploring Badlands National Park through Science and Storytelling  held June 18-21 in South Dakota. Nine educators spent one day in class and three days and two nights in Badlands National Park doing hydrology field studies using GLOBE protocols (water temperature, water clarity, conductivity and pH) in addition to other opportunities. As part of my own professional learning, I set myself a challenge of trying to tell the story of the field studies in ways other than...
