As part of the 2015 Wyoming State Science Fair, Botany graduate students, Christopher Beltz and Caitlin Rottler led one of the enrichment activities where they demonstrated the process of obtaining soil texture to a group of Lander Middle School students.
This activity included both the laboratory and the “feel” method. Students learned how to use a graduated cylinder, hydrometer, and soil sample of a specific mass to determine the percent-by-mass of the sand, silt, and clay. The feel method is commonly used in the field through examining specific features of wet soils in a person’s palms. Soil texture at a given locale is a significant driver of a number of ecosystem functions and can effect which species of plants are able to grow.
