We are the Early Birds (because we catch the worms). Our project explores a potential correlation between a Microclimate’s worm population and clay soil composition. One week before forming our independent research projects, the young women in E.S.S.R.E. plotted and tested five different Microclimates located in the woods behind Roland Park Country School. Using this previously collected data, we, the Early Birds observed a general trend of Microclimates with a high percentage of clay soil having a large average of worms. Alternatively, Microclimates with a lower percentage of clay soil had a smaller worm population. After conducting several T-tests, we determined the two Microclimates with the highest clay soil percentage as well as one with the lowest.
Clay soil has a higher moisture retention rate than both sand soil and silt soil, which compose the majority of the soil in the woods. Earthworms need moisture to avoid drying out and dying, so they are often found in wet soil.
Follow along with our experiment and see the conclusions we came to and how we reached them. Also be sure to check out our sources, acknowledgments, and contact page located on the top menu. Enjoy!
