I use a flipped classroom approach for many lessons, in order to provide more classroom time for student-centered labs and activities. This course is structured around the following six big ideas articulated in the AP Chemistry curriculum framework provided by the College Board:Big Idea 1: The chemical elements are fundamental building materials of matter. And all matter can be understood in terms of arrangements of atoms. These atoms retain their identity in chemical reactions.Big Idea 2: Chemical and physical properties of materials can be explained by the structure and the arrangement of atoms, ions or molecules and the forces between them.Big Idea 3: Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons.Big Idea 4: Rates of chemical reactions are determined by details of the molecular collisions.Big Idea 5: The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter.Big Idea 6: Any bond or intermolecular attraction that can be formed can be broken. These two processes are in dynamic competition, sensitive to external perturbations.The big ideas are correlated and addressed by the units of study in the following manner :UnitsBig Ideas1. Atoms, Reactions and Stoichiometry: Connecting the Macroscopic World to the Microscopic1 and 32. Reactions Involving Electron Transfer: Single Replacement, Redox, and Electrochemistry1 and 33. Particles and Interactions: Energy, Gases and Intermolecular Forces2 and 54. Atomic Structure1 and 25. Molecular Structure: Bonding in Covalent, Ionic and Metallic Substances1 and 26.

New York: D&S Marketing Systems Inc., 2005. Fast Track to a 5 Preparing for the AP Chemistry Examination. Duncan, Pezzi, KnoespelMaterials Spiral notebook to be used as an interactive notebook. At least 70 pages, college ruled, without perforation (if you can find that). I will provide this notebook to you, but you are free to get your own if you like. Notes, diagrams, handouts, quizzes, reflections, labs, and other class materials will be created and kept in this notebook. Carbon copy lab notebook. A folder to keep a limited number of papers that we cannot tape into our notebook.A scientific calculator for home use. A calculator will be provided during class. (TI-30X or something similar. These are about $9. I have some used ones available for sale or rent.)Pen and pencil/eraserLab and Lab WritingCommunicating science is a critical part of doing science. Constructing an argument is a central component of scientific communication. Scientists engage in communication when they discuss their experiments informally at meetings or over the phone or email, present their research formally at conferences, and publish their work in peer-reviewed journals. Scientific writing, and in particular scientific arguments that include claims, evidence, and reasoning, will be an important part of this course.Lab reports are also an important part of this course. As part of AP Chemistry, our lab reports will follow the following format in order to help us use writing to do and learn science. Because writing and scientific argument are such an important part of this course, lab reports will be graded rigorously and will constitute 25% of your grade for the quarter. Every lab report will contain: Title of LabNameName of Lab Partner(s)DatePre Lab Questions (sometimes these will be placed in your interactive notebook)Beginning Question(s): What are my questions about this experiment?Tests and Procedures: What will I do to answer these questions?Observations: What did I see (hear/smell/measure…) as I completed my tests and procedures? Another word for observations is data.Claim(s): What can I claim as a result of my tests, procedures and observations?Evidence and Reasoning: What evidence do I have to support my claim? What mathematical calculations can I do to show that my data supports my claim? How do I know? Do I know if my data is precise and/or accurate? How? Why am I making these claims? Reasoning is the link between your evidence and claims.Reading and Questions: How do my ideas compare with others? If Mrs. Irwin has provided you with questions to answer, they should be answered in this section.Reflection: How have my ideas changed?AssessmentsYour performance in this class will be assessed in a number of ways, both formally and informally. You will keep all of your work in your interactive notebook. In addition to receiving feedback and grades for thesis statements, labs and lab conclusions, and other assignments, you will receive a grade for you interactive notebook at the end of each unit. Assessment TypeApproximatePercentDescriptionHomework10%Homework assignments, when assigned will be graded for completion and will be due at the beginning of class. Lab Writing25%We will be using a writing to learn approach in this classroom. (We will be also do a lot of drawing and labelling). We will write the answers to questions, claim and evidence paragraphs, thesis statements, lab conclusions, data tables, and reflections, among other things. Rubrics/Guidelines will be provided. Interactive NotebookIncluded in Lab WritingAll classwork, notes, and homework will be kept in an interactive notebook in your interactive notebook. It is important that you bring your notebook to EVERY CLASS. If you choose, and there is no written homework, you may keep your notebook in the bin for your block. Instructions and a rubric for the notebook will be distributed and discussed. The notebook will be collected and graded at the end of each unit.Quizzes15%There will probably be at least one short quiz each week. These may or may not be pre-announced. 15 points eachUnit Tests/Projects50%There will be an assessment at the end of every unit. The format will vary, but may consist of multiple choice, fill in the blank, matching and/or free response. Retest PolicyStudents who score below a 70% on a unit test will be invited to take a retest. In order to be allowed to take the retest, the student must complete a test correction sheet for the original test. The retest grade will replace the original grade in the gradebook. Retests will be offered during specific time periods, either before or after school or during Pride. If students cannot be at school during those times, we will discuss other options.Late Work and AbsencesAll work must be turned in at the beginning of class or when I have said it is due. Work turned in late will not be accepted except under the following conditions:IllnessField TripOther legitimate reason (excused by your teacher).AbsencesIf you are absent, it is your responsibility to make up any missed assignments. Check your class period’s folder in the While You Were Out bin for missed work. The scope and sequence, notes, assignments and their due dates will be posted on the class website. Any homework or classwork missed will be due the next class period. If you are absent for a test, you are expected to make up the test. Appointments to make up a test must be scheduled ahead of time to come before or after school or during a Pride.Class ExpectationsRespect yourself, and the opportunity you have been given to learn in this classroom.Respect others and their needs, both in and out of the classroom.Respect our environment: in the classroom, in the school, and outside.Safety ExpectationsSafety is of the utmost importance in chemistry. For this reason, you will be expected to wear goggles and follow lab rules during every lab. Failure to wear goggles will result in removal from that lab and a grade of 0. Lab safety will be discussed in detail at the beginning of the semester. BYOT ExpectationsWe will use our technology, including our phones, as a learning tool in this classroom. In order to respect each other and give ourselves the best environment to learn, we will follow the follow technology guidelines:RED: Possession OnlyAll devices/phones/ipads/tablets must be SILENT and OUT OF SIGHT.Electronic devices may be confiscated by faculty if visible or in use.YELLOW: Specified UseElectronic Devices are permitted only for a specific purpose as instructed.Permission may be revoked if off task.GREEN: General UseUsage is permitted without distracting others.Making or receiving phone calls is not appropriate.Loss of network access or other consequences possible for violating Acceptable Use Policy.Charging: You may charge your phones/other devices as needed in the SPECIFIED AREAS. Ask Mrs. Irwin where the specified areas are.Poll Everywhere account: We will use poll everywhere as a way to answer quick questions and complete formative assessments during class. Everyone will sign up for a poll everywhere Inappropriate BehaviorSafety Shower: Students are not permitted to pull the safety shower handle unless it is an emergency. Any violation of this policy will result in time spent cleaning the room and an additional 10 hours of community service for the science department.Eye Wash: Students are not permitted to play with or turn on the eye wash unless it is an emergencyVandalism: Please take care of all furniture and equipment. Any violation of this policy will result in immediate disciplinary action from administration.Cheating/PlagiarismIt is expected that you will follow the Park View Honor Code at all times. Cheating, plagiarism and other academic dishonesty will result in a 0 for that assignment. Plagiarism includes not citing your source correctly or copying someone else’s work word for word.. Cheating includes copying someone else’s work or letting other people copy your work. There will be a lot of group work during labs in this class, but everyone must turn in their own work in their own words.Extra HelpMs. Irwin will be available for extra help on Tuesdays and Thursdays before school and on Wednesdays after school, and by appointment. If you need help and those times do not work for you, please ask and we can arrange a time. Ms. Smith is also available after school on most days for extra help.LabsAP Chemistry Investigation #7: Stoichiometry: Using the Principle That Each Substance Has Unique Properties to Purify a Mixture: An Experiment in Applying Green Chemistry to Purification (LO 3.5)Hostage and Fosset: Experiment #1: An Introduction to Qualitative AnalysisGuided Inquiry: AP Chemistry Investigation #8: Redox Titration: How can we determine the actual percentage of H2O2 in a drugstore bottle of hydrogen peroxide.

During the winter of 2014-2105, the water in Montgomery County turned brown, and the County claimed the cause to be increased solubility of manganese levels in the water as a result of high levels of sodium chloride in the water supply from snow removal efforts. Students will gather a sample of water from a local source in the fall and again in April. They will analyze both sources to compare the levels of chloride in the water at different times of the year, and complete a report analyzing possible sources of the difference and ramifications of the sodium chloride pollution.Activity: Salt Solution (Iowa State) (Mini) Unit 10: The Nernst Equation and Electrochemistry AgainClass Periods: 1Chapters: 18AP REVIEW Class Periods: 5Chapters: AllAP EXAM: Monday, May 4, 2016, 8:00 AMFinal WordsDon’t panic if some concepts or vocabulary seem difficult or confusing. Ask for help, and we will work through the concepts together. The key to chemistry is to develop problem solving strategies. Decide what you know, what you want to find out, and come up with a strategy to get from the first point to the second. Even if you don’t arrive at the “accepted” answer, you will make progress in your learning if you follow your logic.-38101166370SignaturesI have read a copy of the syllabus and grading policy.Student Name: _______________________________ Signature: ___________________________________________Parent Name: ________________________________ Signature: ___________________________________________Phone # (h): ______________________ (w): _________________________ (c): _________________________Parent Email: ____________________________________________________Concerns: ................
