Schoolyard SITES Curriculum Workbook includes a narrative description of the SITES professional development program and the Project Planning Guide. The Project Planning Guide outlines the steps and decision-making required to identify a NGSS-aligned and local project, design the investigation, and inform the new citizen science curriculum. As one’s planning transitions from pedagogical decisions to classroom activities, the Project Planning Guide serves as an organizing and connecting document. In essence, it is a series of templates and worksheets that educators can use to develop a citizen science curriculum for K-5 students.
