Brian Kaestner, a science teacher at Saint Mary’s Hall in San Antonio, TX and an AP Environmental Science Summer Institute leader, used LabQuest 2 and a Vernier CO2 Gas Sensor to sample steam vents along the rift zone of Kilauea volcano on the island of Hawaii. He used the built-in GPS of LabQuest 2 to sample time and distance throughout the rift zone, in addition to using sensors to collect CO2 and temperature data. While he hiked with his team, he practiced using LabQuest 2 with his iPad so that he could teach his AP Summer Institute participants how to use the Connected Science System.
