The Big Idea: (1) Energy can be changed from one form into another form, but energy cannot be created or destroyed.
(2) Heat is energy that moves from an object at a higher temperature to an object at a lower temperature.
Vocabulary: Energy, PE, KE, mechanical energy, thermal (heat) energy,
chemical energy, electrical energy, sound energy, light energy, nuclear energy,
law of conservation of energy, conduction, convection, radiation
Objectives:
Explain the relationship between potential and kinetic energy.
Explain energy transformation in terms of the Law of Conservation of Energy.
Compare/contrast the 3 forms of heat transfer: conduction, convection, radiation.
GPS:
S8P2.a Explain energy transformations in terms of energy.
S8P2.b Explain the relationship between potential and kinetic energy.
S8P2.d. Describe how heat can be transferred through matter by the collision of atoms (conduction or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).

The Big Idea: Matter is described by its properties and may undergo changes.
Vocabulary: matter, mass, volume, weight, density,
Objectives:
Compare & contrast physical and chemical properties (with ex).
Compare & contrast physical and chemical changes (with ex).
Standards:
S8P1.d Distinguish between physical (density, melting/boiling point, etc) and chemical properties (reactivity and combustibility) of matter.
S8PP1.e Distinguish between changes in matter as physical or chemical (development of gas, formation of precipitate, and change in color)
