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.

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 17th 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 discussions...

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...

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...

Bird Beaks and What they Eat Overview:  Students identify ideal beak shape for food. Age: Upper primary (4th and 5th graders) assisted 1st graders Materials: Bird beak/food handout Straws Dixie cups Juice Tweezers Bowls Wild grain rice Slotted spoons Cooked noodles (macaroni or similarly shaped) Chopsticks Gummy bears White rice Scissors Marshmallows (jumbo) Plan: Ask students why birds have beaks and what they are used for - allow time for discussion. Read a book about beaks to the group. I used Birds Use Their Beaks by Elaine Pascoe. After reading, discuss...

In the early 1980’s, I chaired a group of scientists exploring the idea of a comprehensive satellite mission to study all aspects of the global environment. The group was diverse with expertise covering the range of Earth science disciplines from geology, ecology, oceanography, limnology, glaciology, and atmospheric science and their various sub-disciplines.  Their first recommendation was take today’s data today. In all of Earth science there is the recognition that we have only one Earth to study. How Earth works is revealed by watching it change in a comprehensive manner and...
