This manual is part of a series of materials designed to reinforce essential concepts in physical science through interactive, language-sensitive, problem-solving exercises emphasizing cooperative learning. The manual is intended for limited-English-proficient (LEP) students in beginning physical science classes. The materials are for teams of two students, the student and the tutor, with a separate workbook for each. Questions appear in the student workbook, prompts and answers in the otherwise identical tutor workbook. This combined document consists of the "Tutor Version" followed by the "Student Version." Unit 2 focuses on physical science terminology, symbolism, and graphic representations. A glossary of physical science terms and notations is given, followed by exercises testing comprehension and vocabulary. Students are encouraged to consult the glossary, which reinforces terms and provides practice in manipulating the language. A section describing the uses of various graph types is included, and students are asked to interpret, select, and draw graphs. The final section covers chemistry, including laboratory safety, equipment, experimental design, symbolic notation, and basic molecular concepts. (MSE)
