UNIT 1: PROPERTIES OF MATTER

PART 2: PHYSICAL & CHEMICAL PROPERTIES/CHANGES

3 weeks: September 28, 2009-October 16, 2009

Georgia Performance Standards:

S8P1b:Describe the difference between pure substances (elements and compounds) and mixtures.

S8P1c:Describe the movement of particles in solids, liquids, gases, and plasmas states.

S8P1d:Distinguish between physical and chemical properties of matter as physical (i.e., density,

melting point, boiling point) or chemical (i.e., reactivity, combustibility).

S8P1e:Distinguish between changes in matter as physical (i.e., physical change) or chemical

(development of a gas, formation of precipitate, and change in color).

S8P1g:Identify and demonstrate the Law of Conservation of Matter.

Essential Questions/Skills:

  • Describe the characteristics of matter.
  • Recognize that matter is made of particles in constant motion.
  • Relate the three states of matter to the arrangement of particles within them.
  • Define and compare thermal energy and temperature.
  • Relate changes in thermal energy to changes of state.
  • Explore energy and temperature changes on a graph.
  • Explain why some things float and others sink.
  • Describe the common physical properties of matter.
  • Explain how to find the density of a substance.
  • Describe chemical properties of matter.
  • Identify physical and chemical changes.
  • Exemplify how physical and chemical changes affect the world you live in.
  • Determine whether or not a chemical reaction is occurring.
  • Determine how to read and understand a balanced chemical equation.
  • Describe how a chemical reaction exemplifies the law of conservation of mass/matter.
  • Examine some reactions that release energy and others that absorb energy.
  • Explain the law of conservation of mass.

Enduring Understandings:

  • Matter can neither be created nor destroyed but can be changed from one form to another.
  • Matter can be described by its physical and chemical properties.
  • Chemical elements possess their own characteristic properties, (density, boiling point, melting point, solubility, etc.) and these properties are used to distinguish one element from another.
  • Compounds are made of two or more kinds of atoms held together chemically (bonded).
  • Energy is involved in chemical and physical changes.
  • We get energy from the compounds that make up our food.
  • As the energy of particles changes, their movement changes and the phase in which matter is present might change.
