The project aims to serve the national interest by creating a collection of earth and space science laboratory investigations designed to increase the scientific literacy of undergraduate non-STEM majors. Each investigation is carefully crafted to emphasize the nature of science and progressively increase the level of scientific inquiry expected from students. Through this approach, the curriculum supports students in understanding the process of science, learning key earth and space science concepts, developing scientific skills, and gaining confidence and interest in STEM. The collection represents a significant contribution to undergraduate education by being specifically designed for two-year college students, both online and in person, without requiring specialized equipment. Importantly, the approach supports implementation across institutions regardless of available funding, resources, or instructional modality. In addition, the project strengthens undergraduate STEM education by sharing the collection and underlying approach with educators nationwide and offering training on effective implementation and adaptation. Ultimately, the project fosters the development of opportunities for students to become engaged, competent, critical consumers of scientific information. The goals of the project are to: 1) advance innovation in earth and space science courses at two-year colleges, 2) promote the success of non-STEM majors at two-year colleges by improving scientific lit
