The Twelve Units

The Michigan Content Expectations for High School Chemistry have been divided into 12 Units of Instruction, as seen below. Each unit below contains lessons, resources, and support materials that support the teaching of the corresponding standards, content statements, and specific content expectations for that unit.

Some of the documents below are saved as a Microsoft Word 2007 (docx) file. There is a free download from Microsoft that allows for the viewing of Word 2007 documents. The URL is http://www.microsoft.com/downloads/details.aspx?FamilyID=3657CE88-7CFA-457A-9AEC-F4F827F20CAC&displaylang=en

Unit 1 - Atomic Theory

  • Order in the universe is exhibited through the location and function of subatomic
  • particles and the likeness of atoms of individual elements.
  • A strong force is needed to hold the nucleus together in all atoms.
  • Radioactive dating is the direct function of the timed decay of radioactive atoms.

Unit 2 - Periodic Table

  • The periodic table organizes the known elements into periods and families with similar properties.
  • The periodic table is organized to display trends in the characteristics of elements.
  • The type of chemical bonding determines some characteristic properties of materials.

Unit 3 - Quantum Mechanics

  • The emission spectrum of individual elements is always identical and can be used to identify the elements.
  • Electron transition within energy levels can account for a specific energy emission or absorption within atoms.

Unit 4 - Introduction to Bonding

  • Chemical bonds form either by the attraction of a positive nucleus and negative electrons or the attraction between a positive ion and a negative ion.
  • The strength of chemical bonds can be measured by the changes in energy that occur during a chemical reaction.

Unit 5 - Nomenclature and Formula Stoichiometry

  • Chemical compounds always have the same formula and the same composition.
  • The formal charge on ions determines the ratio of the ions in an ionic compound, just as the apparent charge on atoms determines the ratio of the atoms in a covalent compound.

Unit 6 - Equations and Stoichiometry

  • Balanced chemical equations always exhibit conservation of mass and conservation of heat.
  • The same number of all gaseous molecules will occupy the same volume under the same conditions.
  • Chemical reactions carried out in the same fashion will always produce the same products.
  • Breaking of chemical bonds consumes energy while formation of bonds releases energy.

Unit 7 - States of Matter

  • Particles in all matter are in constant motion until the temperature reaches absolute zero.
  • The order and organization in the universe is illustrated in the pressure, volume and temperature relationships which can be predicted by models, mathematical equations and graphs.

Unit 8 - Advanced Bonding Concepts

  • Many physical properties of substances can be determined by knowing the type of bond structure that exists within the substance.
  • Forces that exist between atoms can be classified into specific categories.

Unit 9 - Thermochemistry and Solutions

  • Heat released or absorbed in chemical reactions is proportional to the amounts of reactants consumed.
  • When a reversible process occurs, the same amount of energy is involved no matter which way the reaction proceeds. The difference will be if the energy is released or absorbed.

Unit 10 - Acid/Base

  • The environment is impacted by chemical reactions on earth.
  • Acids, bases and pH are systems developed by man to help describe natural systems.

Unit 11 - Redox/Equilibrium

  • Many redox (oxidation-reduction) reactions are a source of energy.
  • Redox reactions significantly impact humans in both positive and negative ways.
  • In a closed system, many reactions will reach equilibrium. Changes to the equilibrium can be predicted by using Le Châtelier's Principle.

Unit 12 - Thermodynamics

  • Chemical compounds and chemical reactions strive toward states of highest disorder as does every thing in the universe.
  • Bond formation releases energy to the system.
  • Chemistry Power Standards
