  1. Frayer Models Terry Blanch & Jeff Spraggins: Physical Science

  2. Definition Characteristics Concept Word Examples Non-Examples

  3. Chemical Properties Framework for Learning

  4. Def: the ability of a substance to transfer energy from one place to another. Typically think of conductivity in terms of heat or electricity • How well a substance can allow charge to move through it (current). • Substance can transfer electrical or thermal energy efficiently Conductivity Copper (Cu) Solution of NaCl Examples Glass (SiO2) Pure H2O Non-Examples

  5. Def: the state in which a substance becomes evenly distributed throughout a solution Think of sugar in water. • Solvent molecules are attracted to the substance being dissolved. • Substance spreads out and becomes surrounded by solvent molecules Dissolved Sugar in water. Solution of NaCl Examples Glass (SiO2) Oil Non-Examples

  6. Chemical Bonding Framework for Learning

  7. Def: a type of chemical bond between atoms that gained or lost electrons; a bond between ions Metal atoms ‘give up’ their valence electrons to non-metal atoms • Made of metal and non-metal atoms • Dissolves in water • Conducts electricity when dissolved but not when solid Ionic Bonding NaCl CaBr2 Examples O2 CO Non-Examples

  8. Def: a type of chemical bond that is formed when valence electrons are shared between some atoms. Creates small stable units within the substance. • Made of nonmetal atoms • Some dissolve in water, some don’t • Do not conduct electricity • Tend to be liquids, gases, or soft solids Molecular Covalent CO H2S Examples KBr MgCl2 Non-Examples

  9. Def: a type of chemical bond that is formed when valence electrons are shared between all surrounding atoms. Atoms are covalently connected with each other in all directions-like a grid or network. • Made entirely of nonmetal atoms • Does not dissolve in water • Do not conduct electricity • Very hard solids Covalent Network SiO2 Diamond (C) Examples CO2 NaI Non-Examples

  10. Def: a type of chemical bond that is formed when valence electrons are shared between all atoms in the substance Valence electrons are free to move throughout the substance like a ‘sea’ of electrons • Made entirely of metal atoms • Does not dissolve in water • Conducts electricity • Bendable Solids Metallic Bonding Copper (Cu) Bronze (Cu and Sn) Examples Graphite (C) H2O Non-Examples
