COURSE PREREQUISITES: Algebra 2, Physical/Earth Science COURSE DESCRIPTION: This course teaches the nature of matter, matter’s chemical and physical properties, chemical bonding, chemical reactions and equilibrium, chemical quantities and solutions, acids, bases, and buffers, and oxidation-reduction chemistry. The objective of the course is to build on the student’s existing knowledge of chemistry, to explore chemistry as it applies to examples in and out of the classroom, and to integrate chemical principles with other areas of science including physics, biology, environmental science, biochemistry, and chemistry in society.. A scientific calculator is required for this course. The calculator should have an exponent key (EE or EXP) and a log key (LOG). The math prerequisite for this course is Algebra 2 (or taken concurrently with this course). COURSE OBJECTIVES (The objectives for the LAB COMPONENT of Chemistry Level 1 are the same as those of the LECTURE): 1) Students explain the safe practice of handling chemicals, identification of laboratory glassware; identify the precision of glassware, and the safe disposal of chemical wastes. recognize safety and disposal information of a chemical on a Material Safety Data Sheet (MSDS) in terms of hazards, personal protective equipment, and the safety features in the lab used to control the hazards. 2 compare the precision of volumetric glassware and understand the limitations of laboratory measurements; calculate the property of an unknown substance using laboratory measurement and appropriate significant digits. 2) Students predict the properties of chemical elements and compounds with knowledge from the Periodic Table, prepared reference tables, and laboratory measurement.identify the differences between heterogeneous and homogeneous mixtures, solutions, alloys, and changes of state. use the chemical nomenclature system to identify the names of Type 1, Type II, and Type III compounds. predict the formation of a solid in a chemical reaction; predict the solubility of of salt using the solubility rules and a solubility chart. use the electromagnetic spectrum to understand the emission spectra of elements; use emission spectra to understand the wave-mechanical model of atomic theory. use and apply physical and chemical properties of the elements to understand their position on the Periodic Table. predict the properties of untested elements in terms of their atomic size, nuclear force, ionization energy, electron configuration, and their activity with other substances (for example: oxygen, the Halogens, and water). 3) Students identify the bonding ability of elements to form compounds, and identify the intermolecular forces (IMF) that govern their behavior. draw Lewis structures of molecules according to Lewis rules; identify examples of molecules that are exceptions to the rules. assemble simple molecules and identify their geometry; determine bond polarity and molecular polarity using an electronegativity table. test the solubility of simple alcohol molecules and determine opportunities for dipoledipole interactions between solute and solvent. determine the boiling point of four organic compounds and after ranking their order, use intermolecular force (IMF) theory to explain their order. based on the polarity of solutes and solvents, discuss why some compounds travel further than others in a chromatography experiment. predict the orbital hybridization of compounds using orbital hybridization theory 4) Students use graphs, charts, and experimental data to determine the rate at which chemical reactions occur. plot potential energy diagrams and determine: ΔH, Ea, A.C., and the effect of a catalyst and an inhibitor on the rate of a reaction. predict the shift of a chemical equilibrium system when an external stress is placed on the system according to LeChatelier’s principle. discuss how the factors of temperature, surface area, gas pressure, and concentration affect the rate of reaction according to the collision theory. 5) Students use mathematical strategies, the Periodic Table, and reference values to predict measurable quantities in chemical reactions. convert quantities of chemicals from grams to moles to particles to liters of a gas using stoichiometric relationships. solve problems of gases with respect to volume, pressure, temperature, and moles of a gas using appropriate gas laws. determine the molar volume of a gas using Avogadro’s Law, Dalton’s Law of Partial Pressure, and the Combined Gas Law. 3 6) Students use the concepts of equilibrium, stoichiometry, and solution chemistry to understand acid-base relationships. compare the definition of acids and bases according to Lewis, and Bronsted-Lowry models. use conjugate acid-base pairing to identify the strength of acids and bases and correlate this understanding with acid and base dissociation constants, Ka and Kb. calculate pH problems using logarithmic and anti-logarithmic formulas. prepare a standard acid solution and titrate an unknown base solution to determine its molarity. prepare a chemical buffer system and test the buffer to measure its effectiveness. conduct an acid rain investigation to determine the ability of a simulated lake water to resist a change in pH. determine the Ka value of 6 weak acids and rank the acids ability in order of increasing strength. 7) Students use the concepts of electronegativity and oxidation numbers to predict oxidation-reduction reactions. identify the oxidation numbers of elements and elements in a compound according to redox rules. balance redox reactions according to the half-reaction method. assemble an electrochemical cell and identify the anode, cathode, electrolyte and direction of electron flow; measure the voltage generated by an electrochemical cell (lemon battery).

A+ A AB+ B BC+ C CD F Requirements and Expectations for Class 1. Students are expected to bring to class: textbook, laboratory notebook, pencil or pen, and when requested a scientific calculator with an EE key and a LOG key. 2. Students are expected to make up work in a timely fashion. 3. Homework assignments, lab reports, pre-labs and post-labs are due on the assigned date. 4. Students are expected to show respect and responsibility during class time. 5. Attendance is very important. The student will be at a distinct disadvantage when a topic is missed – it will be his or her responsibility to make up missed class work. 6. Homework is very important to understanding chemistry concepts. AP Lab Experiments will require preparing a pre-lab in your journal to identify disposal and safety consideration. The procedure for the lab experiments should be pre-read and recorded in your journal in your own words. It is essential that students complete the pre-lab to obtain an understanding of logistics and safety aspects of the experiment. 7. Make-up for missed experiments can be completed at a time pre-arranged between student and instructor. Expectations for Students Absent from Class Students are advised that absence does not excuse them from meeting course requirements. All written assignments are to be submitted the day they are due. If an emergency arises, and a student must be absent from class, the student is requested to send an e-mail before class begins with attached assignments that are due that day. A student may e-mail assignments (if absent) by midnight the day of class without having a letter grade deducted from that assignment. In addition, the student must provide the instructor with a hard copy of the assignment at the next class. The instructor is not responsible for printing out student assignments. If a student missed a class and has late work, the student assumes the responsibility to make arrangements with the instructor when and where the makeup work will take place. 6 If a student knows of an upcoming absence, the student must conference with the instructor (before the absence) for work that will be assigned. Note on laboratory investigations – AP Experiments: All labs listed, activities and experiments, are conducted by students - usually in lab groups of three. The AP laboratory experiments are borrowed largely from the Flinn Manual for AP Chemistry Experiments. Each experiment introduces at least one new concept (usually more than one) and it’s the student’s goal through the investigation to grasp the concept(s) after collecting the data and writing a post-lab to the investigation. Students are required to keep a separate laboratory journal. Before the experiment is conducted, students are asked to do a pre-lab - this involves reading over a copy of the laboratory procedure and rewriting the procedure in their laboratory journal in their own words. The pre-lab includes the title of the lab, date, objective or objectives, materials, chemicals and equipment, safety and disposal considerations, and the students own interpretation of the laboratory procedure in a step-by-step approach so that the student will be able to conduct the experiment successfully without the original copy of the lab procedure. The pre-lab should also include room for data collection and/or expected observations. For example, if the experiment involves conducting a titration, then the student should have a prepared data table in their journal to collect the titration data. After the investigation is complete, students are asked to analyze their data. I will either prepare instructions for analysis of data, or ask the students to follow the discussion questions as outlined in the original procedure. To complete the post-lab, the student analyzes the data according to guided questions provided, carries out necessary math calculations, calculates a percent error if the experiment involves a quantitative analysis, and identifies at a minimum three sources of error. The student is also asked to conclude the post-lab with five new ideas the student can take away from the lab – the new ideas/applications should be a reflection of the objective(s) of the lab. The completed AP Experiments (as noted in the WEEKLY READINGS/LAB ASSIGNMENTS/EXAM SCHEDULE above) are worth 25 points. Non-AP Experiments are worth 10 points. AP Experiments Rubric for Post-lab Write-ups (AP Labs) The following grading scheme for post-lab write-ups will be used for evaluation. 4 The lab write-up includes a completed pre-lab Title, Objective(s), Materials, student’s interpretation of the Laboratory Procedure, room for observations or a data table, safety and disposal considerations. The post-lab includes an analysis section (section that evaluates the observations or data collected), the observations and/or data are interpreted correctly and thoroughly tying the objective(s) to the results of the experiment. Equations or chemical formulas are used to help with explanations during evaluation. When necessary, mathematical calculations are shown to interpret results. When the investigation is a quantitative analysis, a percent error is completed, is accurate, and a minimum of 3 sources of error are identified. Conclusions are drawn from the evaluations section (5 new ideas that the student learned) that demonstrate the student has a good understanding of the 7 objective(s) of the lab and can now apply them. Note: Since post-labs are worth 25 points, the actual score of the post-lab will be weighed on thoroughness and accuracy. A score of a 4 can actually lead to a possible point score of 25-22 depending on attention to detail of the sections mentioned in the explanation above. 3 The lab write-up should include a completed pre-lab Title, Objective(s), Materials, student’s interpretation of the Laboratory Procedure, room for observations or a data table, safety and disposal considerations. One or more of these sections may have been left out. The post-lab includes an analysis section (section that evaluates the observations or data), the observation and data are interpreted but the understanding may be correct in some cases but vague or incorrect in others. One or more of the opportunities for evaluation may have been only mentioned or left out. The student attempts to tie the objective(s) during the evaluation of results. Equations or chemical formulas are used in part to help with explanations during evaluation. When necessary, mathematical calculations are shown to interpret results. When the investigation is a quantitative analysis, a percent error is completed, but may not be accurate, and less than 3 sources of error are identified. Conclusions are drawn from the evaluations section (5 new ideas that the student learned) that demonstrate the student has a good understanding of the objective(s) of the lab but one or more conclusions is not clear, or is not tied in with the objective(s). Note: Since post-labs are worth 25 points, the actual score of the post-lab will be weighed on thoroughness and accuracy. A score of a 3 can actually lead to a possible point score of 21-18 depending on attention to detail of the sections mentioned in the explanation above. 2 The lab write-up does not include a completed pre-lab Title, Objective(s), Materials, student’s interpretation of the Laboratory Procedure, room for observations or a data table, safety and disposal considerations, or includes only part of these sections. The pre-lab has no mention of safety and disposal considerations. The post-lab includes an analysis section (section that evaluates the observations or data), the observations and data are interpreted but the understanding is not correct or consistent as one idea is discussed after the next. One or more of the opportunities for evaluation may have been only mentioned or left out. The student through their discussion does not have a clear idea of the objective(s) of the laboratory procedure. Equations or chemical formulas are used in part to help with explanations during evaluation, but one or more have been left out. When necessary, mathematical calculations are shown to interpret results but the math or interpretation is not correct. When the investigation is a quantitative analysis, a percent error is completed, but is not accurate, and less than 3 sources of error are identified. Conclusions are drawn from the evaluations section (5 new ideas that the student learned) that demonstrate the student has a good understanding of the objective of the lab but two or more conclusions are not clear, or are not tied with the objective(s). Note: Since post-labs are worth 25 points, the actual score of the post-lab will be weighed on thoroughness and accuracy. A score of a 2 can actually lead to a possible point score 8 of 17-14 depending on attention to detail of the sections mentioned in the explanation above. Long-term assignments are assignments of more than five days in duration. Failure to hand in work by the last acceptable due date will result in a grade reduction of 10% per day.
