AEPA Chemistry NT306 study guide
AEPA Chemistry NT306 · Work through your exam, one topic at a time.
The AEPA Chemistry test (test code NT306) is one of the Arizona Educator Proficiency Assessments, a suite of knowledge and professional-knowledge tests used in Arizona's teacher certification process. The program is administered by Pearson, and the official AEPA site lists NT306 Chemistry among its subject knowledge tests. The AEPA Chemistry NT306 study guide has 5 sections and about 1,525 words.
01Nature of Science
Nature-of-science questions test whether you can reason about how chemistry knowledge is built, not just recall facts. Core concepts: the scientific method as a flexible cycle (observation, question, hypothesis, experiment, analysis, revision); the difference between hypothesis, theory, and law (a theory explains why ; a law describes what happens, often mathematically - neither is a stepping stone to the other); variables (independent = manipulated, dependent = measured, controlled = held constant); and the role of peer review, replication, and falsifiability.
325 words, about 2 min02Matter and Its Properties
You must classify matter and predict properties from structure. Key concepts: pure substances (elements, compounds) vs.
310 words, about 2 min03Chemical Reactions
You need to write, balance, classify, and predict reactions, and to apply stoichiometry. Core concepts: conservation of mass (balancing equations); reaction types (synthesis, decomposition, single replacement, double replacement, combustion, acid-base neutralization, redox); solubility and precipitation; net ionic equations; the mole concept and molar mass; limiting reactants and percent yield; and solution concentration (molarity).
282 words, about 1 min04Thermodynamics and Kinetics
This domain pairs energy changes with reaction rates. Thermodynamics concepts: enthalpy (ΔH), exothermic vs.
293 words, about 1 min05Atomic and Molecular Structure
You must connect atomic structure to the periodic table and to bonding. Key concepts: subatomic particles and isotopes; electron configuration and orbital filling (Aufbau, Pauli, Hund); periodic trends (atomic radius, ionization energy, electronegativity, electron affinity); ionic vs.
