This Great Ideas for Teaching Students (GIFTS) paper describes a Project-Based Service Learning (PBSL) opportunity recently implemented in a first-year engineering course. PBSL is a vital instructional approach in contemporary engineering education. It encourages students to deepen their understanding while forging meaningful community ties. PBSL experiences are student-centered (yet tailored to the course objectives and community needs). They foster collaboration, nurture creativity, and build analytical skills while applying practical engineering solutions to real-life issues. This paper describes a short-term PBSL that we used in a core first-year engineering course (for all engineering majors across the University) to give them an experience of how they could contribute to the community using their engineering skills and knowledge. The activity involves the building and testing of Corsi-Rosenthal (C-R) boxes (DIY Air Purifiers) that trap ~60% of particles in indoor environments to improve indoor air quality. Students carried out the project in small groups (3-4 students) in the First-Year Design Laboratory for two to four weeks. At the end of the project, we distributed the C-R boxes to local elementary schools, housing for multiple-sclerosis patients, and veterans. We have implemented this project for three years allowing over 1200 students to participate in this PBSL. In their final portfolios, students highlighted how this learning experience helped them meet the course objectives. This GIFTS paper describes this project and our implementation strategies to allow others to similarly implement the project. We also include an analysis of the student perceptions towards this PBSL.
