Learning TARGETS
Identify kinetic or potential energy in everyday situations.
- Energy is the ability to do work or the ability to move an object.
· Energy occurs in two main forms, potential and kinetic.
· Kinetic energy is energy of motion found in objects or substances.
· Potential energy is energy possessed by an object as a result of its position or height
above the ground rather than its motion.
Demonstrate the transformation between potential and kinetic energy.
·Potential energy changes to kinetic energy and back again.
·The transformation from potential to kinetic energy occurs when the object is in motion.
·The transformation from kinetic to potential energy occurs when an object transfers from a moving object to an object in a position with potential energy.
·As an object falls, potential energy decreases and kinetic energy increases.
· As an object is raised kinetic energy decreases and potential energy increases.
Identify and describe the three ways energy can be transferred.
·Radiation is the transfer of energy by waves.
· Conduction is the transfer of heat energy by direct contact between particles.
·Convection is the transfer of heat energy through liquids and gases by moving particles.
·Energy can travel from place to place.
Potential = STORED/WAITING
Kinetic = MOTION

Energy Transfer: Conduction, Convection, Radiation
Thermal energy moves from a hot item to a cold item. Thermal energy is transferred in three ways:
Conduction -- transfer of heat energy through contact of particles
Examples: egg cooking in frying pan, spoon in soup bowl, hands rubbing together
Watch this video to see how heat conducts through paperclip: http://www.youtube.com/watch?v=kv0-9KRoPek
Convection -- transfer of heat energy through liquids and gases through moving particles (cycles of hot/cold)
Examples: convection oven, boiling water in a pot, heating systems in houses, hot air balloon

Radiation -- transfer of heat energy through waves
Examples: the sun, tanning beds, microwave
