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.




Gathering data Once you have determined what protocols to use for your project, you will need to develop a plan for gathering the data. It might consist of using automated data collection or making your own measurements. Also, it may include finding data taken by others, such as when you compare your observations with those of another GLOBE school. Automated Data Collection If you are using an automated data collection device or devices, verify that the data are being recorded properly before your official testing timeframe. You will want to monitor that the data are being...

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...

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...

Consider the rain gauge used in GLOBE, CoCoRaHS, and other citizen science programs. Just four pieces plus 2 mounting screws – an inner graduated cylinder, an outer cylinder, a cap/funnel, and a mounting bracket. The area of the outer tube is exactly 10 times the areas of the inner tube and the cap/funnel, so the graduations on the inner cylinder can be spaced ten times further apart. Thus, 0.2 mm of rain fills the inner tube to a depth of 2.0 mm, which one can read. In addition, if heavy rainfall fills the inner cylinder, the rest of the rainfall overflows into the outer cylinder,...
