1. Essential Question: How does energy change from one form to another?
Agenda
Ram Bleat- Period 1 Only
Bell Ringer
Types of energy (Card Sort)
Notes- Types of energy & energy transfer
Types of Energy Card sort- address questions and misconceptions

2. Transferring Thermal Energy Topic 1 Lesson 2 & 3

3. Review
Temperature is the measure of the total kinetic and potential energy in an object – a number value, use thermometer
Heat- the transfer of thermal energy from a warmer object to a cooler object.
Thermal expansion- all substances expand with heated and contract when cooled. Exception is water
Different materials contract and expand at different rates
The Law of Conservation of Energy: energy can not be created or destroyed, only transferred or changed from one form to another

4. Heat/ Energy is transferring around you all the time!!!
Heat transfer is:
NOT random
Transfers in one direction
The energy Always moves from a warmer area to a cooler area.

5. Thermal energy is transferred from place to place by:
CONDUCTION
transfer of thermal energy by collisions between particles in matter.
CONVECTION
transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place.
RADIATION
transfer of energy by electromagnetic waves.

6. occurs in solids, liquids, and gases.
Conduction
occurs in solids, liquids, and gases.
Examples:
Convection
occurs in fluids. Rising of warmer fluid and sinking of cooler fluid
forms a convection
current

7. Radiation The transfer of energy by electromagnetic waves.
Does not require matter (can move through air…)

8. Energy Transformations
Sometimes, it is necessary to transform one type of energy into another to get work done.
Write down 4 examples of your own.
