The STEM Guides Project aims to enhance STEM learning for underserved rural youth aged 10-18 by creating a cohesive informal STEM infrastructure and supporting creative outreach models in low-income areas of Maine. Funded by the National Science Foundation, the project establishes networks of STEM guides who connect youth with local resources and initiatives, leveraging community assets like libraries. The initiative anticipates reaching 3,000 youth and fostering deeper STEM engagement through partnerships and resources over its five-year timeline.
