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.
