Seychelles Integrated Science (SIS), a 3-year laboratory-based science program for students (ages 11-15) in upper primary grades 7, 8, and 9, was developed from an extensive evaluation and modification of previous P7-P9 materials. This P7 SIS unit is designed to: (1) introduce students to and familiarize them with working in the school laboratory; (2) make them aware of the need for care and caution while working in the laboratory; and (3) instruct them in the correct use of the metric ruler, balance, graduated cylinder, thermometer, and stopwatch. Provided for the unit is a student workbook and a set of teaching notes. The teaching notes include an overview of the SIS program, the general aims of the unit, and a lesson plan for each topic area. Each lesson plan includes a suggested time frame, a list of objectives, a list of equipment needed, and a suggested lesson format. This format includes suggestions for introducing the lesson, instructional strategies (emphasizing procedures for student activities), and evaluation methods. The student workbook includes procedures for completing the unit activities and a list of new words keyed to page numbers in the workbook. (JN)
