Energy The ability to do work or cause change
Law of Conservation of Energy Energy cannot be created nor destroyed
Examples of Potential Energy By looking at these examples, what do you think potential energy is?
What is potential energy? Stored energy – energy that is not in motion Roller Coaster EX: – 5_int_rollercoaster/
Examples of Kinetic Energy What do all of these pictures have in common?
What is kinetic energy? Energy in motion Examples of potential vs kinetic: –Youtube.com–Youtube.com

Thermal Energy
What is Thermal Energy? The energy of heat – It transfers from hotter objects to cooler objects
Temperature The measure of how hot or how cold something is
Conduction
What is Conduction? The transfer of heat that occurs when 2 objects of different temperature touch
Conductor
What is a Conductor? A substance that heat or electricity can easily flow through
Insulator
What is an Insulator? A material that protects or resists the transfer of heat, electricity or noise
Convection
The transfer of warm air up and cool air down in a circular motion
What do you think is making the warm air rise & the cool air sink?
So, what’s more dense…warm air or cool air? Cool air = more denseWarm air = less dense
Radiation
What is Radiation? The transfer of heat through empty space
Identify the following as conduction, convection, or radiation: Heat we feel from the sun
Identify the following as conduction, convection, or radiation: The heat you feel when you touch a hot stove
Identify the following as conduction, convection, or radiation: Heat you feel when you touch a cup of hot chocolate
Identify the following as conduction, convection, or radiation: This is responsible for making macaroni rise and fall in a pot on the stove
Identify the following as conduction, convection, or radiation: Heat you feel when you sit around a campfire
