A collaboration of five key states, an array of scientists and educators, and an experienced science curriculum team will develop and establish a National Model Earth Science Lab Course, providing standards and exemplary activities that will reach hundreds of thousands of students annually. The team will create a lab handbook with guidelines and exemplary activities in Earth system science and environmental literacy. All materials will be published on the web and available for free to teachers and students. The initial set of four exemplary labs will engage students in field experiences, classroom experiments and active use of data and computer visualizations dealing with oceans, atmosphere and other NOAA domains. These hands-on learning experiences will help students develop environmental literacy, build deep understandings of Earth as a system, and apply scientific thinking, problem-solving and data analysis. The participating states view this as filling a crucial gap in the approval and implementation of Earth science as a standard high school lab science. This project builds on planning done in a series of projects: National Conference on the Revolution in Earth Science Education, State Alliances for Earth Science Education, and Planning Grant for Earth System Science as a High School Lab Science. This National Model responds directly to essential needs expressed by the states. The labs will comply with national and state standards for Earth science and meet requirements for a true lab science course. This project is bold and ambitious, but also essential for states striving to strengthen their high school Earth science offerings, and it is a practical response to NOAA's need to infuse its resources into the fabric of public Earth science education.
