The GLOBE Estonia Learning Expedition 2023 has, among other subjects, embarked on a
profound exploration of the intricate world beneath our feet—the soil. This report offers an
extensive overview of the expedition's objectives, research inquiries, methods, discoveries, and
their profound repercussions. Spearheaded by our dedicated team of students, led by the seasoned
instructor Eelika Kiil (University of Tartu), and supported by Regina Univer, this journey of
discovery was placed in various locations, from the Emajõgi river bank to the park of Ülejõe.
This research investigates the influence of environmental factors on soil properties in specific
geographical areas. Through meticulous data collection and analysis, our study supports three
hypotheses. The results reveal variations in soil temperature, moisture levels, and pH across
different sites, providing valuable insights into the complex interplay between ecological
elements and soil characteristics.
“How can I stand on the ground every day and not feel its power? How can I live my life
stepping on this stuff and not wonder at it?” (Logan, 2007).
