The prominent two-year-college honor society has conducted several Service Learning projects for its officers, student members, and community. For example, ACC’s Sigma Phi Chapter of Phi Theta Kappa has researched adaptive clothing and the role inclusive clothing can play in a person's daily life. This project gave the officers the opportunity to understand students with disabilities. Sigma Phi also worked on the wetlands interpretation project in collaboration with Hudson Gardens, across the street from ACC in Littleton. This project focused on developing concepts for signage at the Gardens that outlines the historical significance of the area. Historical information was gleaned through academic research and interviews with the South Platte River Park Supervisor, Director of Public Works at the City of Littleton, and members from the Hudson Foundation. A third project Sigma Phi officers have completed was a donation drive held to help the flood victims at Front Range Community College.
For the Fall 2016 semester’s Honors in Action project, Sigma Phi collaborated with internal and external partners to create a visual model illustrating groundwater flux and scarcity that was displayed at the Denver Museum of Nature & Science in order to educate the public about global issues surrounding the protection and sourcing of groundwater. The model has been donated to ACC’s Geology Department to support future groundwater studies.
