Abstract
Abstract: The Full Option Science System (FOSS) series, designed for grades K to 6, consists of instructional modules organized under four topic headings: Life Science, Physical Science, Earth Science, and Scientific Reasoning and Technology. The instructional techniques including hands-on approach, multisensory methods, working alone together (grades K to 2), and collaborative groups (grades 3 to 6) are used to achieve scientific literacy for students and instructional efficiency for teachers. Each module includes a teacher's guide and equipment kits. This module (grades 5 to 6) exposes students to basic concepts of mechanics using two simple machines: levers and pulleys. In activity one, students are introduced to the parts of a lever and explore class one lever systems. They experiment to discover the relationships between the load, fulcrum, and effort in class one levers. In activity two students investigate class two and class three levers and determine the advantages that can be gained by using the each class of levers. In activity three, students work with load, effort, and advantage using a pulley. They investigate and diagram four different pulley systems. In activity four students systematically investigate four pulley systems to discover the mechanical advantage and the length of rope that must be pulled. The teacher's guide consists of a module overview, a set of activity folios, duplication masters for the student sheets, an assessment package (except grade K), FACTs (FOSS Activity Correlation Tables), and equipment inventory lists. The activity folio is a concise booklet for each activity, which provides a lesson plan; background information; a materials list; preparation plans; discussion questions; mathematics, language, social studies, and art extensions; home activities; and suggestions for including a multicultural dimension in the lesson. The equipment kit contains materials for a class of 32 students. Each kit for grades 3 to 6 also contains a teacher preparation video. The assessment packages for grades 3 to 6 including hands-on, pictorial, and reflective assessment are designed to assess student understanding of science processes and content. The duplication masters for the student sheets and assessment packages (grades 3 to 6) are written in both English and Spanish. English and Spanish versions of videotapes and videodisks (laserdiscs) are available separately to supplement this module. (CCC)
