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.




I recently had the pleasure of meeting a GLOBE student named Aspen. I was excited because my favorite type of tree is Aspen (Quaking Aspen to be more specific, Populus tremuloides to be even more specific), and I was able to tell her some of the fun facts about her namesake. My favorite thing about aspens is their bark. The white powder on it can act as sunscreen. It’s only about an SPF of 5 but it’s still pretty cool. The bark also contains chloroplasts which means it can photosynthesize, making it one of the few deciduous trees that do not solely rely on leaves for...

In my previous blog post, I showed the results of my surface temperature experiment. It was a great way to highlight some of the practical ways to use science, and it was yet another way for me to talk about my puppy. My experiment and accompanying blog was straightforward enough. I identified a problem, I designed an experiment, collected data, and presented the results. This is how science is done, right?! With years of experiment experience behind me, this should have been a very fast and easy task, but I had one problem that I forgot to account for, my Attention Deficit Disorder. ...

These are the results from my surface temperature experiment that I discussed in my previous blog post (same title, part 1). Results and Conclusion : Figure 2: Graph of average surface temperatures of the three surfaces over three days including air temperature data lines. My results show that my hypothesis was half right (remember, it’s ok if your data results do not match your hypothesis!). During the day, asphalt was the hottest, concrete was in the middle, and grass was the coolest. The surface temperatures of all three dropped at night, however, I was...

In case you missed it, last month, was all about the 2017 International Virtual Science Symposium . There were over 140 entries from all 6 GLOBE regions. Students submitted reports about their research on all of the “spheres” (hydrosphere, atmosphere, biosphere, pedosphere, and earth as a system) and they were reviewed by a panel of scientists, teachers, and science enthusiasts to be rewarded with stars and badges. I had the wonderful privilege of being able to read through and review several projects. I was blown away with the thought and hard work that went into these projects....

As Earth science has a single uncontrolled object of study, the first rule is to take today’s data today. While ice and sediment cores and fossils can reveal past conditions, the observations that can be made right now cannot be replaced by ones taken later. This goes well with the Native American adage, “You can’t step in the same river twice.” The environment is constantly changing and doing so on a wide range of time and space scales. In a recent video post, Neil deGrasse Tyson said, “One of the great things about science is that it is an entire exercise finding what is true. You...

In the fall of 2016, the students in my Weather and Climate class, GEPL 4490/5490, at the University of Toledo developed projects based on El Nino. The students in class were give the task to look at GLOBE data from a part of the world in which El Nino has an effect. The students were also tasked to do research on El Nino and La Nina to see what it is.   The students looked at the following locations: Taiwan 2015 – Nicole Jablonski, Bailey Hafner, Cortnee Halpin Japan 1998 – Sean Smith, Australia 1998 – Madhusanka Jayawardhana, Josh Coll, and Justin Maluchnik As...

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,...

Hello GLOBE friends! The Evaluation Working Group has recently shared with you the results of the 2015 survey that was sent to the GLOBE teachers. The results from this survey, along with the results from the Annual Partner Survey provided us  with useful information as to how to better support  GLOBE in the classroom. Among other things,. the feedback we had from the teachers was that they are asking for evaluation tools they can use in their classrooms and for guidance on how to use these  tools. During our discussions in the Working Group we thought about this...

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...

Concerns regarding the impact of global warming on vector-borne diseases have intensified interest in the relationship between atmospheric factors and dengue fever incidence. Global climate change poses the threat of serious social upheaval, population displacement, economic hardships, and environmental degradation. Changes in temperature, rainfall and relative humidity have potential to enhance vector development, reproductive and biting rates, shorten pathogen incubation period and encourage adult longevity. In addition, changes in wind direction, velocity and frequency will have an...
