The unit consists of four organizing sub-themes: (1) earth (providing activities on the physical shape of the earth and landform formations; (2) geography (emphasizing map reading skills); (3) universe (exploring the components, processes and future projects for the solar system); and (4) natural environment (addressing ecological concepts and processes). Each sub-theme contains an introductory statement, student activities for lower grades (K-3) and upper primary grades (4-6), and a teacher's copy for each student worksheet.
