Energy 101
Energy Forms and Transformations
• Essential Question
– Where does energy come from?
– How is energy transformed/transferred in our
daily lives?
– We need to understand the basics of energy
before understanding solar energy.
What is energy?
•Ability to do work or cause
change
•Produces Warmth
•Produces Light
•Produces Sound
•Produces Movement
•Produces Growth
•Powers Technology
Jigsaw Energy Forms
In your groups, write
down what you know
about these types of
energy:
Stored Mechanical
Thermal
Nuclear
Sound
Electrical
Chemical
Gravitational
Radiant
Motion
Potential Energy
Gravitational Energy
– energy an object or
substance has because
of its position
Anything “up high”
Potential Energy
Stored Mechanical
Energy – stored in an
object by the application
of force
Must push or pull on an
object
Potential Energy
Nuclear Energy –
energy stored in the
nucleus of an atom
Holds the atom
together
Potential Energy
Chemical Energy –
energy stored in the
bonds between atoms
Holds molecules
together
Kinetic Energy
Mechanical (Motion)
Energy – movement of
objects or substances
from one place to
another
Kinetic Energy
Electrical Energy –
movement of electrons
Kinetic Energy
Sound Energy –
movement of energy
through substances
in the form of
longitudinal/compres
sion waves
Kinetic Energy
Radiant Energy –
electromagnetic
energy that travels in
transverse waves
Kinetic Energy
Thermal (Heat) Energy –
internal energy of a
substance due to the
vibration of atoms and
molecules making up the
substance

Energy Transfers
1 – Energy can not be created nor destroyed,
only changed.
•Law of Conservation of Energy
•First Law of Thermodynamics
2 – Energy will always transfer from high to
low.
3 – No energy transfer is 100% efficient.
Electrical Energy
Electricity Basics
Electricity is…..
•
•
•
•
The flow of electrons
The energy sent out by batteries and
generators (current electricity)
The shock you can get from rubbing your
feet on the carpet (static electricity)
A bolt of lightning! (static electricity)
All Matter is Made up of Atoms
MATTER
(Diamond, coal)
ELEMENT
(Carbon, Oxygen)
ATOM
(particles)
Atoms
What is an Atom?
– The smallest component in all things
– Made up of three smaller particles
• Protons (+)
• Neutrons (no charge)
• Electrons (-)
– Strive for stability
• Charged atom = ion
Opposites Attract
Attraction
+ +
_ _
• Particles with opposite charges attract each other.
Charged Atom (Ion)
Atoms
+++
++
----
Stable Atom
Positive Ion
Negative Ion
• Stable atoms have equal protons and electron
• Stable atoms have no charge
• Free electrons will seek positively charged ions to
create stability
Electricity Simulation
•Opposites Attract – Find a match!
•Simulate Current Electricity
Simulating Electric Current
Current Electricity
• Electric current is the movement of free
electrons from atom to atom
• To start the free electrons moving an
electromotive force is needed.
– Batteries
– Generator
Current is like water flow
• Flow of water is similar
to flow of electrons
• The pressure (voltage)
determines how fast the
water (electrons) move
through the pipe (wire)
• There is no current
without voltage
Flow

Voltage & Current
• Voltage
– Pushes electrons
– Measured in Volts
– Comes from batteries, electric outlets,
generators
• Current
– Flow of electrons
– Measured in Amps
– 1 amp = 6,240,000,000,000,000 electrons
moving past a point every second

How is Electrical Energy Generated?
• Coal Plant Simulation
• (Adapted from NEED.org, Primary Energy
Stories and More, A Cool Coal Story)

How Do You Get Electricity?
Where Does Arizona Get Electricity?
There are 10 sections.
Think in terms of fractions or
percentages. If you color in 5 sections,
that would be 𝟏 𝟐 or 50%. If you colored in
3 sections, that would be 𝟏 𝟑 or 30%.
Try to think of all the resources
Arizona uses.
Assign a value to each.
