The document provides materials and instructions for 4th grade students to create relief maps of California showing the locations of the 21 Spanish missions, as part of a project to demonstrate their knowledge about the missions. Students will research information about their assigned mission, then plan and construct a model of it using materials like cardboard, glue, and markers to display the mission's geographical features and region. The project aims to help students understand and represent the physical and human geography of California as expressed through the mission system.
