Year-Long Plan: ChemistryThis year-long plan represents a Chemistry class that would be offered to sophomores and juniors

at a high school in the Columbus City School District. Dates in this plan are estimated based on the Columbus City School calendar for the 2014-2015 school year. In this plan, I estimated three snow days, two assembly days, two weeks of state testing, two SAT/ACT testing days, and two PD days. Days when there is no school are shaded in dark green and days when there is reduced instruction time are shaded in light green. The planned progression of units is a combination of the Arizona State Modeling Curriculum that I plan on using in my future classroom and the Columbus City School Pacing Guide and Content Alignment. I have made some modifications in the order of units since students do not take a state or graduation test for Chemistry.

This year-long plan incorporates 14 separate units. Seven will be covered before winter break and seven will be covered after winter break. Each unit ends with one review day and one test day. Tests are scheduled for either Wednesday or Friday and never occur after a break. Unit 5 ends on the same day as the end of a grading period, but it would be explained to students that grades for that unit would be included in the 2nd grading period rather than the 1st. All other units end at least two days before the end of a grading period. After Unit 7 and Unit 14 there will also be a Cumulative Exam that covers the previous 7 units. This exam can be used as either a make-up test for students who missed a unit test, or extra credit to replace their lowest test score.

Unit OutlineFirst three days of school: These days will be spent covering student, teacher, and class introductions. After this, we will do a content introduction activity and a review of lab safety. Student should be introduced to lab protocols and procedures.

Unit 1 – Matter (Allotted Time: 12 days)

o Mass, volume, density (4 days)o Measurements (4 days)

Accuracy and Precisiono Conservation of Mass (1 day)o Significant Figures (1 day)o Review (1 day)o Unit Test (1 day)

Unit 2 – Energy & Particles in motion (Allotted Time: 10 days)

o Diffusion (1 day)o Thermal Energy, Particle Motion, and Temperature (3 days)

Unit 5 – Counting (Allotted Time: 7 days)

o Avogadro’s number (1 day for each section in this unit)o Moleso Relative and molar mass o Percent compositiono Empirical and molecular formulaso Reviewo Unit Test

Unit 6 – Internal structure (20 days total)

This unit is larger and covers more topics. I have split the unit into three smaller sections with a quiz at the end of each section rather than a test. At the end of Unit 6, students will take their cumulative exam. This exam will focus mainly on Unit 6 rather than having a separate test devoted to Unit 6 alone.

Unit 6.1 – Atomic Structure (Allotted Time: 8 days)

o Review parts of the atom, charges, and the Thompson cathode ray experiment (2 days)o Rutherford Gold Foil experiment (1/2 day)o Intro to the History of atomic models: Dalton, Thompson, Rutherford, Bohr, Schrodinger

(1.5 days)o Calculate atomic mass and isotopes (2 days)o Review (1 day)

o Unit Quiz (1 day)

Unit 6.2 – Ionic, Metallic, and Covalent Bonding (Allotted Time: 7 days)

o Properties of molecules, ionic lattices, and network covalent solids (1 day)o Polarity (1 day)o Ionic, polar covalent, and covalent bonds (2 days)o Metallic properties (1 day)o Review (1 day)o Unit Quiz (1 day)

Unit 6.3 – Chemical Names and Formulas (Allotted Time: 8 days)

o Naming binary ionic compounds (3 days)o Giving formulas for ionic and molecular compounds (3 days)o Review (1 day)o Unit Quiz (1 day)

Review of Unit 6 (1 day)

Mid-year Cumulative Exam (1 day) – This test will be offered to students as either a make-up test for missed tests or an extra credit exam to replace their lowest test score. The exam will focus mainly on Unit 6 topics to help sum everything up, but will also include other topics from the year. The aim of this exam is to help students build and add to their knowledge instead of learning units in isolation and then forgetting about them.

6.5 days (yellow on the calendar) of buffer space - I plan on using this time to compensate for units that take longer than planned. If this is not necessary then I plan on using the time to review past topics so that students are ready to move on to chemical reactions. If there is still significant time left over before winter break, then I may supplement with one of the three possible “Additional Units” that will be detailed at the end. They include Hydrocarbons, Life Chemistry, and Nuclear Chemistry.

Unit 7 – Chemical Change (Allotted Time: 12 days)

o Rearranging atoms (2 days)o Different types of reactions and Balancing Equations (5 days)o Macroscopic chemical change observations (2 days)o Endo vs exothermic reactions (1 day)o Review (1 day)o Unit Test (1 day)

Unit 8 – Intro to Stoichiometry (Allotted Time: 11 days)

o Determining Number of Moles from a Balanced Equation (2.5 days) o Determining the Mass of Products/Reactants from a Balanced Equation (2.5 days)o Percent Yield (2 days)

o Limiting Reactant and Theoretical Yield (2 days) o Review (1 day)o Unit Test (1 day)

Unit 9 – Stoichiometry Applications (Allotted Time: 10 days)

o Ideal Gas Law (5 days)o M1V1=M2V2 (3 days)o Review (1 day)o Unit Test (1 day)

o Effective collisions (1 day)o Catalysts (1 day)o Entropy (2 days) o LeChatelier’s Principle (2 days)o Review (1 day)o Unit Test (1 day)

Unit 14 – Acids and Bases (Allotted Time: 10 days)

End of Year Cumulative Exam: This will be a cumulative exam that covers the second half of the year (Units 7-14). It will be a make-up or extra credit test opportunity for students much like the Mid-Year exam.

Potential time at the end of the year (There are three extra days indicated on the calendar): This time is allotted for the following possibilities:

1. The previous units took longer than expected and overflow into this time2. Three potential “Additional Units” could be covered depending on student interest.

a. Unit 15 – Hydrocarbon Compoundsi. Combustion reactions

ii. Polymersiii. Fossil fuels

b. Unit 15 – Life Chemistryi. Cellular Respiration

ii. Biological Moleculesc. Unit 15 – Nuclear Chemistry

i. Types of radiationii. Radioisotopes

iii. Radioactive Decayiv. Fission, Fusion, and Energy Considerations
