STEM Network Blog Intro

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.

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 incorrect about asphalt...

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. Of...

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, which...

In most scientific research an important test is whether the results of an experiment can be repeated, typically repeated by another lab and research group. A result that cannot be confirmed in this way is generally viewed as invalid. This is a great test for controlled experiments where virtually identical experimental conditions may be achieved. In Earth science research involving observations of the natural world, experimental conditions cannot be reproduced. For environmental research the standard must switch for repeatable to intercomparable – capable of being compared. Research...
