Student Name ___________________
Ms. Brantley
Per _____
ENERGY is ……….
 the ability to do_______________________
 the ability to make things __________________
 NOTHING happens without ENERGY!
You can’t see or touch energy. It DOES NOT take up space or have mass. Energy is NOT_______________!
THE ENERGY SONG
Melody is from "That's the Way I Like it" by K.C and the Sunshine Band, by H.W. Casey and R. Finch.
Lyrics by Doug Edmonds.
Doo doo doo doo doo doo doo
Doo doo doo doo doo doo doo
Refrain:
Energy, uh-huh, uh-huh, it can't be cre-a-ted!
Energy, uh-huh, uh-huh, it can't be, can't be destroyed!
Energy, uh-huh, uh-huh, it can't be cre-a-ted!
Energy, uh-huh, uh-huh, it can't be, can't be destroyed!
The Law of Conserva-tion of energy
Energy can only be transformed!
Energy exists in many forms
But never created or destroyed. (Refrain)
Two main types -- of energy
Potential and kinetic energy.
Potential - is energy that's stored
Kinetic is motion energy! (Refrain)
Here're some forms -- of potential energy
Gravitational, chemical, nuclear, and elas-tic.
And some forms -- of kinetic energy
Electrical, mechanical, heat and light! (Refrain) and then doo, doo, doo ... followed by Refrain.

Potential – stored energy
Kinetic – energy of motion
energy of an object’s position
Gravitational Energy
energy stored because of an object’s
position




Anything ABOVE the ground
water behind a dam
snow on a mountain
skydiver
Radiant (light) Energy
travels in waves, most are not visible



Sun (solar)
x-rays, UV
radio waves, microwaves
---------------------------------------------------------------
Sound Energy
movement of energy through
substances (vibrations)
------------------------------------------------------------------
Chemical Energy
stored in chemical bonds




Fossil Fuels – oil, natural gas, coal
Biomass – food, wood, plants, garbage
Living things
Batteries

music, an explosion, sonic boom
---------------------------------------------------------------
Electrical Energy
movement of electrons (parts of atoms)


electricity
lightning
-------------------------------------------------------------------------------------------------------------------------------
Elastic Energy (Stored Mechanical)
stored when an object is compressed or
stretched

Mechanical (motion) Energy
movement of objects or substances



wind
water (hydropower)
machinery
Compressed springs & elastic bands
---------------------------------------------------------------
Thermal (heat) Energy
energy of moving atoms; internal
energy in substances
-----------------------------------------------------------------
Nuclear Energy
stored in the center of an atom (nucleus)

Uranium – U atoms are split in a nuclear
power plant to release energy


geothermal – heat within the earth
Heat moves from warmer to cooler
substances by one of these methods:
Conduction
Convection
Radiation
2
Law of Conservation of Energy
states that……
Energy CANNOT be _______________ or ___________________,
It is transformed (or _____________________)
into other forms of Energy!!!!
Complete the energy transformations in the chart below.
Event
Original form of
energy is …..
It is transformed into….
Resulting form(s) of energy
Example: Lighting fireworks
Chemical
Radiant
Turning on a lamp
Coal used to make electricity
You eat an apple, then ride a bike
A car is turned on
Releasing a rock in a sling shot
Wood burning
A battery-powered robot starts
moving
Sun shines on a solar panel and
the school zone lights flash
(your turn to try)

Thermal (Heat) Energy Transfer
Thermal energy is a form of KINETIC energy – it always moves from _______________ to _____________.
It can move in the 3 ways listed below.
Below each one, you should list some examples and draw a picture to help you remember each of them.
Conduction:
transfer of heat through a material by ____________________ ________________.
Convection:
transfer of heat in a _____________________ or a __________________ as a result of the movement of
the liquid or gas.
Radiation:
transfer of heat via electromagnetic (______________) waves through space.
How are all three forms of heat transfer alike? _____________________________________
How are all 3 forms of heat transfer different? _____________________________________

Renewable vs. Non-Renewable Sources of Energy
Define:
Renewable (R) - ___________________________________________
Non-Renewable (N)- ________________________________________
List advantages and disadvantages of the different sources of energy below.
Type of
