Unifying concepts are the overarching theme in which the science content is taught. Below are the unifying concepts for the district Chemistry course.
 * [|**Abilities to Do Scientific Inquiry**]** — ** Inquiry involves engaging in scientifically oriented questions, giving priority to evidence in responding to questions, formulating explanations based on evidence, connecting explanations to scientific knowledge, and communicating and justifying explanations.
 * [|**Understandings About the Nature of Science**]** — ** The development of scientific knowledge is based on questioning current knowledge, using empirical facts to develop logical theories, and verifying observations and claims.

= Chemistry (Physical Science) Standards = Students apply an understanding of atomic and molecular structure to explain the properties of matter, and predict outcomes of chemical and nuclear reactions.

1. Matter has definite structure that determines characteristic physical and chemical properties. 2. Matter can change form through chemical or nuclear reactions abiding by the laws of conservation of mass and energy. 3. Atoms bond in different ways to form molecules and compounds that have definite properties.


 * __Matter__** Process or Skill
 * 1) Know definition of Matter.
 * 2) Be able to give examples of and tell difference between: Mixtures vs. substances (non-mixtures); Homogenous vs. heterogeneous mixtures; Elements vs. Compounds.


 * __Measurement__** Process or Skill
 * 1) Be able to do metric conversions. Know the different basic units: meters; liters; grams.
 * 2) Know the prefixes: Kilo-,Hecto-, Deka-, Basic Unit, Deci-, Centi-, Milli-. Know approximately how big the common metric units are.
 * 3) Use the appropriate tool for measurement
 * 4) Know the four states of matter: Solid; Liquid; Gas; Plasma.
 * 5) Of the three most common states (Solid; Liquid; Gas) know the properties of each: shape; volume;compressibility; speed of molecules; distance between molecules.
 * 6) Know the names of the temperatures at which a substance changes state: freezing point, etc.
 * 7) Be able to list and APPLY the 6 major steps of the Scientific Method.
 * 8) Be able to calculate volume with the displacement method.
 * 9) Know what density is and how to calculate density; know what is denser liquids or solids and why.
 * 10) Be able to draw a density column: know how density affects whether something sinks or floats.
 * 11) Know the density of water and be able to recognize it; know that water is denser than ice (one exception).
 * 12) Know and understand these words: Hardness; Elasticity; Brittleness; Malleability; Tensile Strength; Viscosity.
 * 13) Know about buoyancy and Archimedes’ Principle; know how to figure out whether an object will sink or float and how much cargo it can carry.


 * __Atoms__** Process or skill
 * 1) Know the structure of the atom: the subatomic particles; where they are; what their charges are.
 * 2) Know these words: element; isotope; nucleus; atomic number; mass number; molecule; compound; proton; neutron; electron; atom.
 * 3) Know about charges repelling and attracting, what electron orbits electrons fill up first, and how the nucleus stays together.
 * 4) Know the atomic scientists and their contributions to our atomic theory.
 * 5) Be able to find this information from the periodic table: element name; symbol; atomic mass; atomic #; group and period.
 * 6) Be able to find the number of valence electrons and the molecular mass of a molecule.


 * __Nuclear Reactions__** Process or Skill
 * 1) Know the differences between fission and fusion; their waste products.
 * 2) Know the differences between the three kinds of radiation: alpha; beta; and gamma.
 * 3) Know why atoms decay.
 * 4) Know these words: carbon dating; half-life; chain reaction.
 * 5) Be able to do a half-life calculation.
