Tuesdays 12-1 pm and Thursdays 1-2 pm

Hello 2019-2020 Chemistry Families, 
Below you will find a comprehensive listing of the objectives for Chemistry classes in the Commonwealth of Virginia.  Objectives which were covered prior to the close of school on March 13, 2020 have been high-lighted.  Dates of coverage are noted along with online reviews which may be watched for a quick refresher.  
Students are strongly encouraged to practice and self-test using the links available on the HOMEWORK tab (to the left on this page).  Here you will find many practice games and quizzes, notes, simulations, and more.  A particularly great tool for practice questions is the link entitled "J Labs Practice Test Questions".  Once on this site, students can select topics to test from which correspond to the 5 main objectives for chemistry (listed below).
Should you have any questions, please email me at
I wish you all the very best and hope that this message finds you healthy and well!!


The Chemistry standards are designed to provide students with a detailed understanding of the interaction of matter and energy. This interaction is investigated through the use of laboratory techniques, manipulation of chemical quantities, and problem-solving applications. Scientific methodology is employed in experimental and analytical investigations, and concepts are illustrated with practical applications that should include examples from environmental, nuclear, organic, and biochemistry content areas.


Technology, including graphing calculators, computers, and probeware, are employed where feasible. Students will understand and use safety precautions with chemicals and equipment. The standards emphasize qualitative and quantitative study of substances and the changes that occur in them. In meeting the chemistry standards, students will be encouraged to share their ideas, use the language of chemistry, discuss problem-solving techniques, and communicate effectively.


The Chemistry standards continue to focus on student growth in understanding the nature of science. This scientific view defines the idea that explanations of nature are developed and tested using observation, experimentation, models, evidence, and systematic processes. The nature of science includes the concepts that scientific explanations are based on logical thinking; are subject to rules of evidence; are consistent with observational, inferential, and experimental evidence; are open to rational critique; and are subject to refinement and change with the addition of new scientific evidence. The nature of science includes the concept that science can provide explanations about nature, can predict potential consequences of actions, but cannot be used to answer all questions.


CH.1    The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated produce observations and verifiable data. Key concepts include

  1. designated laboratory techniques;
  2. safe use of chemicals and equipment; Covered September 2019: Review
  3. proper response to emergency situations; Covered September 2019; Review
  4. manipulation of multiple variables, using repeated trials;
  5. accurate recording, organization, and analysis of data through repeated trials;
  6. mathematical and procedural error analysis; Covered September 2019; Review
  7. mathematical manipulations (SI units, scientific notation, linear equations, graphing, ratio and proportion, significant digits, dimensional analysis); Covered September 2019; Review






  8. use of appropriate technology including computers, graphing calculators, and probeware, for gathering data and communicating results; and
  9. construction and defense of a scientific viewpoint (the nature of science).


CH.2    The student will investigate and understand that the placement of elements on the periodic table is a function of their atomic structure. The periodic table is a tool used for the investigations of

  7. electron configurations, valence electrons, and oxidation numbers; Covered Feb/March 2020; Review
  8. chemical and physical properties; and Covered October 2019 : Review
  9. historical and quantum models. Covered December 2019-February 2020;


CH.3    The student will investigate and understand how conservation of energy and matter is expressed in chemical formulas and balanced equations. Key concepts include

  1. nomenclature; Covered November 2019-February 2020:  Review




  2. balancing chemical equations; Covered February 2020:  Review
  3. writing chemical formulas (molecular, structural, and empirical; and Lewis diagrams); General Chemistry Partially covered (molecular and empirical) December 2019-January 2020;  Review

    Pre-AP Classes covered structural and Lewis in February-March 2020:  Review

  4. bonding types (ionic and covalent); Pre AP Chemistry February 2020:  Review
  5. reaction types (synthesis, decomposition, single and double replacement, oxidation-reduction, neutralization, exothermic, and endothermic); and  Reaction types synthesis – single replacement covered in Pre-AP classes just prior to leaving school March 2020:  Review
  6. reaction rates and kinetics (activation energy, catalysis, and degree of randomness). Pre AP Chemistry March 2020:  Review

  1. Avogadro’s principle and molar volume; Covered October-November 2019; Review


  2. stoichiometric relationships;
  3. partial pressure;
  4. gas laws;
  5. solution concentrations; Covered January-February 2020:  Review


  6. chemical equilibrium; and
  7. acid/base theory: strong electrolytes, weak electrolytes, and nonelectrolytes; dissociation and ionization; pH and pOH; and the titration process.


CH.5    The student will investigate and understand that the phases of matter are explained by kinetic theory and forces of attraction between particles. Key concepts include

  1. pressure, temperature, and volume;
  2. vapor pressure;
  3. phase changes;
