Air Temperature

The Air Temperature task is part of the Atmosphere Unit from Global Learning and Observations to Benefit the Environment (GLOBE). In this task, students will use a maximum/minimum thermometer mounted in their instrument shelter to measure current temperature and the maximum and minimum temperatures for the previous 24 hours. Students may also collect current temperature only.

Alkalinity

The Alkalinity task is part of the Hydrosphere Unit from Global Learning and Observations to Benefit the Environment (GLOBE). In this task, students will make a 3-dimensional model of a catchment basin to understand how water moves through the basin and explore how water is affected when there are changes in the basin. They will model the changes in soil water storage over a year. In the classroom, students practice using the instruments or kits for protocols, exploring the range of measurements and sources of variation and error.
