Established by the U.S. Government on Earth Day in 1994, the GLOBE program is an international science and education program that allows students to collect real-time data and report it to a global data set.  As part of the GLOBE program, students have access to the ongoing authentic data set.  Data collection parameters include observations, hands on measurements, and the use of scientific probeware.  Throughout all aspects of the program, students are challenged to think critically and apply science process skills learned across subject areas.
