Through a partnership between North Dakota State University (NDSU) and the Fargo-Moorhead Science Museum (FMSM), with support from the ND EPSCoR Outreach Activities Award, this project developed, implemented, and evaluated evidence-based ecology outreach activities for 3rd–6th grade students in alignment with North Dakota science standards. Using a backward design approach, NDSU faculty and PhD students, and FMSM staff collaborated to create four two-hour ecology-based camps titled: Exploring Nature, Biodiversity Detectives, Soils Alive, and Sensing Our Environment. These camps were offered through FMSM's Nature Labs series at Lindenwood Park in Fargo, ND from June to July 2026. The project directly engaged 45 individuals, including 24 unique student participants and 21 collaborators spanning museum staff, university faculty and graduate researchers, undergraduate students, and community volunteers, with 82 total program registrations and 55 session attendances recorded. Each camp incorporated pre-and post-camp assessments to measure student learning outcomes, alongside real-time facilitator feedback to continuously improve instruction. While sample sizes limited statistical analysis, qualitative findings and participant feedback indicate strong promise for student learning, engagement, and STEM identity development. This project established a reusable, evidence-based model for informal STEM outreach and cements an ongoing NDSU–FMSM partnership. FMSM Nature Labs was conducted in partnership with Fargo Parks and received additional funding support from the North Dakota Natural Resources Trust.
