Course Overview: Chemistry 1 2003350 Purpose of this document: This curricular resource was designed to support teaching and learning in classrooms across Pasco County and provide a sequenced, focused curriculum that supports the acquisition of the Florida Standards and NGSSS using Marzano’s Instructional Framework used to teach standards in this course’s course description. This “road map” for instruction is intended for use within a Professional Learning Community (PLC) as a common planning tool. Grade level PLCs should use this document to jumpstart collaborative discussions around the five guiding questions to plan for student learning. Each unit contains: A Unit Overview With Recommended Pacing Grouped NGSSS: o Content Standards: Each unit was designed around a group of related content standards. They describe what students should know, understand, and be able to do by the end of the unit. o Science Practices: Practices of Science are ongoing standards that should be intentionally planned for every day in every lesson because of their critical role in engaging students as scientists.

Implement Action Plan Standards taught in this course are the NGSSS for Science that emphasize increased opportunities for laboratory investigations. This course incorporates the new Common Core College and Career Readiness and Mathematics Standards as shown below. While the content focus of this course is consistent with the Chemistry I course, Chemistry 1 Honors students will explore these concepts in greater depth. In general, the academic pace and rigor will be greatly increased for honors level course work. Laboratory investigations that include the use of scientific inquiry, research, measurement, problem solving, laboratory apparatus and technologies, experimental procedures, and safety procedures are an integral part of this course. The National Science Teachers Association (NSTA) recommends that at the high school level, all students should be in a science lab or field collecting data every week. School laboratory investigations are defined by the National Research Council (NRC) as an experience in the laboratory, classroom, or the field that provides students with opportunities to interact directly with natural phenomena or with data collected by others using tools, materials, data collection techniques, and models (NRC, 2006, p. 3). Laboratory investigations in the high school classroom should help all students develop a growing understanding of the complexity and ambiguity of empirical work, as well as the skills to calibrate and troubleshoot equipment used to make observations. Learners should understand measurement error; and have the skills to aggregate, interpret, and present the resulting data (NRC 2006, p. 77; NSTA, 2007). Instructional Practices to Support Literacy through Common Core- College and Career Readiness Standards Teaching from a range of complex text is optimized when teachers in all subject areas implement the following strategies on a routine basis: Ensuring wide reading from complex text that varies in length. Making close reading and rereading of texts central to lessons. Emphasizing text-specific complex questions, and cognitively complex tasks, reinforce focus on the text and cultivate independence. Emphasizing students supporting answers based upon evidence from the text. Providing extensive research and writing opportunities (claims and evidence).

The coefficients in a balanced equation give the simplest whole-number ratio among the number of moles of reactants and products in an ideal reaction. Given appropriate data, calculate the percent yield for a process that is non-ideal. Determine the volume of a gaseous product or reactant after solving for or being provided with mass or number of moles, temperature and pressure. Most reactions are non-ideal, i.e., they do not run to 100% completion. A percent yield can be calculated to determine the amounts of product(s) present at equilibrium. Define limiting reactant as the starting material that is used up first in a chemical reaction. The coefficients in a balanced equation along with data concerning the mass of any reactant or product can be used to calculate the amounts of any other reaction component using the rules of stoichiometry.
