Ute Kaden is the first teacher in Brownsville ISD, Texas, to teach AP Physics. To keep the interest of her students at Hanna High School, she literally spans the globe in search of new and exciting ways to bring real-world data into the classroom. Recently she took her Vernier LabPro and sensors to the North Pole! At a latitude of 89° 58.5′ she measured salinity, temperature, barometric pressure, and acceleration due to gravity. Her results? g = 9.801 m/s²
