Required Instructional Materials Chemistry: Visualizing Matter, Holt, 2000. Teacher resources for selected texts Current and sufficient laboratory instrumentation for each of the learning strands Appropriate safety equipment goggles, aprons, eyewash, safety shower, etc. Wall-sized Periodic Table Information technologies internet and library resources Completion/Revision Date Revisions Approved by Board of Education June 14, 2004 Revised November 2006. Mission Statement of the Curriculum Management Team The mission statement of the Science Curriculum Management Team is to promote scientific literacy emphasizing the process, content, and interdisciplinary nature of science. Enduring Understandings for the Course Inquiry is the integration of process skills, the application of scientific content and critical thinking to solve problems. Science is the method of observation and investigation used to understand our world. Matter can be described, organized, and classified for understanding. The law of conservation of matter describes how matter behaves. The periodic table is a tool that can be used to predict properties of elements and how these elements will react with each other. Elements on the periodic table have many applications including those in the medical field to help diagnose and treat ailments/disorders. Elements on the periodic table can be found in different combinations and quantities, forming all the different substances on earth. While some acids and bases are harmful, some are biologically important. The science behind acids and bases can help describe things such as body and environmental chemistry.

Advances in chemistry have personal. societal, and environmental costs and benefits. Polymers are organic compounds composed of carbon chains that can be systematically modified or recycled into other materials. The environment is a complex assemblage of interacting and evolving chemical processes. Temperature is a measure of the average kinetic energy of the molecules. Applied Chemistry - Page 2 of 9
1.0 Scientific Reasoning and Communication Skills NOTE: This learning strand should be taught through the integration of the other learning strands. This learning strand is not meant to be taught in isolation as a separate unit. Inquiry is the integration of process skills, the application of scientific content and critical thinking to solve problems. Science is the method of observation and investigation used to understand our world. LEARNING OBJECTIVES The student will: 1.1 Generate scientific questions to be investigated. 1.2 Apply appropriate instruments needed to collect data precisely. 1.3 Analyze experimental design and data so as to question validity, identify variables, and improve experimental design. 1.4 Develop conclusions based on critical data analysis identifying further investigations and/or questions based on the results. 1.5 Organize data in tables and graphs. 1.6 Utilize graphs in order to determine patterns and make predictions. 1.7 Apply computer-based tools to present and research information. 1.8 Gather information using a variety of print and non-print sources. 1.9 Support scientific arguments using a variety of print and non-print sources. 1.10 Present scientific information orally. 1.11 Present scientific information in an expository format so that it adheres to standard forms of grammar and mechanics.
