STEM Professionals' Blog


The GLOBE International STEM professionals Network (GISN) Blog is an online collaborative effort where scientists associated with GLOBE post their thoughts, comments, and philosophies about a variety of science topics.

GLOBE strongly encourages positive and productive discussions to further advance the scientific understanding of all involved with The GLOBE Program.




Authors: Claudia Caro and Olawale Oluwafemi (Femi) Our participation in the International Virtual Science Symposium (IVSS) as judges has allowed us  to learn more about  the scientific experiences of students involved in the GLOBE Program. As members of the GLOBE Science Working Group with backgrounds in Geography and Biology, we would like to share our findings about the importance of the IVSS in the GLOBE community and give you some advice to empower your participation in this extraordinary yearly event. Why an International Virtual Science Symposium? Knowledge...

When you start writing your GLOBE report for IVSS, it might be difficult because you might not sure where to start. We tend to start writing the Methods section first because it is something you did it yourselves and it should be relatively easy and straight forward to write. Second, you should write the Results section, do graphs, tables and texts (think of a best way to present your cool data to the whole world). Third, you should start writing the Introduction stating your hypotheses and predictions. The next step would be the Discussion section. It is funny to say but as scientists, we...

Observations of daily precipitation have been a part of GLOBE from the beginning. At the start, GLOBE’s participation model was that schools would take measurement following all of the original 17 protocols. Atmosphere temperature, precipitation, cloud, and soil moisture measurements were to be collected daily at a site easily accessible to the school. A permanent installation of an instrument shelter containing a max/min thermometer mounted to a post along with a rain gauge was the expected norm with other measurements taken nearby. Daily temperature and precipitation measurements were...

From the start, the measurement of daily maximum and minimum air temperature within one hour of local solar noon has been a key GLOBE protocol. The low cost approach was to use a U-tube thermometer housed in a wooden instrument shelter facing away from the equator. The U-shaped tube contained mercury with pins on either side of the mercury. As the air temperature warmed the pin on one side would move while the other pin stayed in place; when the air cooled, the pin on the other side would be pushed up. The pins were held in place by magnetized strips behind the thermometer tube so that...

This time was my first visit to Trinidad and Tobago and to the LAC region. The visit was first of its kinds, knowing vividly that Africans and the People of Trinidad and Tobago have so many things in common in terms of Geography and Historical antecedent.  The motivation for my visit to Trinidad and Tobago started during the 17 th GLOBE Annual meeting at Maryland. Initially, it was just a brief discussion with Henry Saunders (Country Coordinator, GLOBE Trinidad and Tobago). However, after a year, I met Mr. Michael at GLOBE Expedition in New Delhi, India where we had in-depth...
