Background Information Pages
This page provides a written
overview of the lesson topic.
Use this information as a way
to prepare for instruction and
classroom discussion.
Lesson 1
What Is Energy?
Background Information for the Teacher
Energy is a fundamental part of the universe.
It is a source of usable power used to do work.
It is used to light cities, as well as to power
planes, trains, and automobiles. Energy is
required to heat homes, power machinery, and
cook food. Energy is not only found in these
processes, but also in the objects themselves.
When an object is at rest it has potential
energy, or stored energy. When that resting
object begins to move, the potential energy
transforms into kinetic energy. Between the
energy that objects possess and the energy
found in processes, energy can be found all
around us.
In fact, there are many forms of energy. Some
of which include:
• Mechanical Energy: This is the energy
objects have as a result of their motion and
position. Simply put, potential energy plus
kinetic energy equals mechanical energy.
This is the energy that makes wheels turn
and motors spin.
• Solar Energy: This is energy from the sun
that provides heat and light. Solar energy
has become a popular alternative to other
nonrenewable resources in recent years.
• Thermal Energy: This is energy produced by
heat. We use heat to keep warm. We use
heat to cook food.
• Chemical Energy: This is the energy stored
in food, fuel, and other matter. Chemical
energy is released and absorbed, or taken in,
during chemical reactions, such as digestion.
When we eat food, our bodies store the
nutrients as chemical energy. Our bodies
need this energy to move and do work.
Chemical energy is also found in batteries.
• Electrical Energy: When people think of
energy, this is most often what comes to
mind. Electrical energy powers many things
in our homes and offices. It provides light,
entertainment, and heat. Even a gas stove
requires electrical energy!
• Light Energy: This is the energy that allows
us to see objects in a range of vibrant colors
and shades.
• Sound Energy: This is the energy that allows
us to hear our favorite songs and babies
crying. Waves of sound energy vibrate
through rock concerts and movie theaters on
a nightly basis.
The Law of Conservation of Energy states that in
any of these forms, energy cannot be created,
nor can it be destroyed. Energy can only be
transferred or transformed. Therefore, the sum
of all the energy in a system is constant. For
example, if a student is at a resting position on
a swing and her potential energy equals twenty
joules (units of energy), then her kinetic energy
would equal zero joules. As she swings, her
potential energy converts to kinetic energy and
back again. At all points in the pendulum of
her swing, her potential and kinetic energy will
add up to twenty joules. Energy has not been
created or destroyed.
Lesson 1
Energy is everywhere. It is in our bodies, the
earth, and even the sun. Energy is necessary
for life, and at the same time, allows us to
live comfortably. Without energy, life would
not exist.

#15534—Energy Teacher’s Guide
This page provides additional
vocabulary and information that may
be necessary for classroom discussion.
This information is not intended to be
directly taught to students, but can be
shared with them if the need arises.
In addition to vocabulary, this page
may include interesting facts, data and
statistics from around the world, helpful
websites, and diagrams or photos to
support the topic.
Energy is measured using a few different methods. One of the basic measuring units is called
for British thermal unit. One Btu is the amount of heat energy it takes to
increase the temperature of one pound of water by one degree Fahrenheit, at sea level. One Btu
is equal to the energy contained in one blue-tip kitchen match. The energy in one thousand Btus
roughly equals the chemical energy in about four-fifths of a peanut butter and jelly sandwich or
the energy burned during one hour of bicycling.

Energy also can be measured in units called joules. The term joule is named after James Prescott
Joule and is the unit for energy in the International System of Measurement. How are Btus and
joules related? The approximate conversion between units is as follows:
1,055 joules = 1 Btu
1,000 joules = 1 kilojoule
Energy to Burn
If you eat a blueberry muffi
n that has 360 calories,
approximately 1,428 Btus,
you have energy to burn!
In order to burn that amou
nt of energy you could:
• jog for 21 minutes
• bicycle for 1 hour 17
minutes
• mow the lawn for about
1 hour
• vacuum the house for 1

Directions: Follow the steps below to answer the questions. Formulate your
hypotheses and complete your research. Use the materials your teacher has
provided. Record your observations and draw your conclusions. Present your
research on a separate sheet of paper.
Energy is a source of usable power used to do work. Work is done when one object
transfers energy to another object. When an object is at rest it has potential energy,
or stored energy. When an object that is standing still begins to move it has kinetic
energy, or energy of motion. These are not the only forms of energy, however.
Energy is all around us.
Directions: Look at the picture below. Circle the different energy forms and
sources. Then, list all of the forms and sources of energy you found.

The Law of Conservation of Energy says that energy cannot be created or destroyed.
Energy can only be changed. It changes from one form to another. For example,
plants can absorb, or take in, energy from the Sun. They use this energy to create
sugars. When plants do this, they are changing solar energy into chemical energy.
Another change occurs when you turn on the lights in your classroom. You are
changing electrical energy into light energy. These changes happen all around us.

Lesson 4
Mechanical Energy
Background Information for the Teacher
An airplane flies through the clouds. A
pitcher throws a baseball. A hammer drives
a nail into a piece of wood. In each of these
scenarios, potential and kinetic energy combine
in a system that does work. This is called
mechanical energy. Mechanical energy is the
energy objects have because of their motion
or position.
Work is done on an object when one object
transfers energy to another object, causing
the second object to move. The first object
exerts a force that causes the second object to
move. That force could be a twist, turn, pull,
push, or throw. A push is a force applied by

(push)

60
#15534—Energy Teacher’s Guide
an object that repels another object away from
it. A pull is a force applied by an object that
draws another object towards it. For example,
mechanical energy allows a hammer to apply
force to a nail. The force of the hammer causes
the nail to move and be driven into a piece of
wood. Because the hammer has mechanical
energy in the form of kinetic energy, it is able
to do work on nails.
We are able to see examples of mechanical
energy in many of our everyday actions. This
includes riding the bus to school and riding a
roller coaster.
Mechanical energy can also be seen in more
complicated systems. A bicycle is composed of
a variety of parts, each of which has its own
potential energy. The pedals, chains, gears, and
wheels all possess potential energy. When an
outside force, such as a person pushing a pedal,
acts on one object in the system, that potential
energy is converted into kinetic energy. As the
pedal turns, the kinetic energy transfers to the
chain and gears, causing them to turn. It is in
this transfer that work is done and mechanical
energy can be seen. Work continues to be done
as the chain and gears transfer kinetic energy to
the wheels, causing them to spin, sending the
bike speeding down the road.
Mechanical energy is one of energy’s most basic
forms. It is often converted into other useful
forms, such as electrical energy and thermal
energy. Often, mechanical energy produces heat
in addition to other forms of energy. When this
heat is not used to do work, it is called waste
heat. These energy conversions can be seen
in systems as complicated as a hydroelectric
power plant or as everyday as a matchstick. As
long as there is work being done, you will know
mechanical energy is there. Mechanical energy
keeps things moving.

Lesson 4
Mechanical Energy
More to Know
Additional Vocabulary
entropy: a measure of the energy that is not available for work during a thermodynamic process
thermodynamics: the study of the connection between heat and work and the conversion of one
into the other
Thermodynamics
Thermodynamics is the study of the connection between heat and work and the conversion of one
into the other. Two major laws govern this study:
1.The First Law of Thermodynamics is the Law of the Conservation of Energy. This law states
that energy cannot be created or destroyed, only converted from one form into another.
2.The Second Law of Thermodynamics states:
•Although energy cannot be created or destroyed, some energy in a conversion may not be
used to do work—it is wasted. For instance, you may notice that your laptop computer
emits heat after you have used it for a while. The computer is not using that heat energy
to do any work—it is wasted heat.
•Heat will normally flow from areas of high temperature to areas of low temperature.
•A system that is closed, preventing new energy from being introduced, will eventually reach
a state of maximum entropy in which all energy is lost as heat and no energy is available
to do work.

Marble Roller Coaster
Directions: Read the question below and formulate a hypothesis. Use the
materials your teacher has provided to test your hypothesis. Create a record of your
experiment on a separate sheet of paper.
Question
How do hills affect the mechanical energy of a roller coaster?
Hypothesis
Formulate and record a hypothesis. (What is the answer to your question?)
Experimental Design
1. Make your track by taping two u-shaped channels end-to-end.
2. Choose and record a loop diameter between 30-50 cm (about 12-20 in.).
3. Curl the end of the track into a loop of the desired diameter. Tape the
loop together where the two tracks meet at the bottom.
4. Tape the other end of the track to a bookshelf to make a ramp.
5. Now, you can tape the loop to the floor.
6. Measure and record the starting point of the track.
7. Run a marble down the track three times. Did it make it through the
loop each time? Record which result happened most often (the mode).
8. Change the height and repeat trials. If the marble makes it through the
loop most of the time, lower the height. If it does not, raise the height.
Observations
How did the height of the ramp affect the ability of the marble to complete
the loop? Record your observations.

Lesson 4
Mechanical Energy
Moving, Moving, Moving
Mechanical energy is the energy objects have because of their motion or position.
A moving car has mechanical energy. This is due to its motion. A moving baseball
has mechanical energy. This is because of its high speed and its position above the
ground. A book at rest on the top shelf of a bookcase has mechanical energy. This
is due to its position above the ground.
Mechanical energy also involves the ability to do work. Work is done on an object
when one object transfers energy to another object. The transfer of energy
causes the second object to move. That move could be a twist or turn. It could
be a push or pull. It could even be a throw. A push is a force from an object that
repels another object away. A pull is a force from an object that draws another
object closer. For example, mechanical energy is present when a hammer pushes
a nail into wood. The force of the hammer makes the nail move. The hammer has
mechanical energy. It is able to do
work on nails.

Mechanical energy is all around us.
Your hand pulls a door. The door
opens. A bowling ball pushes a pin.
The pin falls. A wrecking ball hits
a building. A hit is like a push. The
building falls.
Mechanical energy can be changed
into other forms of energy to do
work. Mechanical energy can be
changed into electrical energy.
Mechanical energy may also produce
heat. When the heat is not used to
do work, it is called waste heat.
Whenever work is being done,
you know mechanical energy is
there. Mechanical energy keeps
things moving.

D mechanical energy.
Comprehension
Directions: Read the paragraph below. Then answer questions 4 and 5 on the
following page. Fill in the bubble next to the correct answer for each question.
Thinking Is Hard Work
Every day, students read, write, listen, and speak. Parents often ask about all the
work done at school. But what is work? Work is done on an object when one
object transfers energy to another. So if you are reading a textbook, what energy
is being transferred? You may think work is not being done If you are not lifting
a book or turning a page. But work is being done! Parts of your brain called
neurons (nOOr-ohns) receive energy signals from your eyes and transfer those
signals to other parts of your brain. So the next time you want to get some work
done at school, pick up a book and let your brain do the rest.

Lesson 4
TIM BRADLEY
Wrecking Ball Mayhem
Background Information
A wrecking ball is a heavy steel ball. It hangs from a crane. A wrecking ball can destroy an
entire building. It does this with mechanical energy. Mechanical energy is the energy that
an object has because of its motion or position. An object that has either of these forms of
mechanical energy is able to do work. A wrecking ball works to break apart a structure.
The wrecking ball has potential energy at its highest point in the air. The heavy ball has
kinetic energy as it falls. The ball hits a building. It applies a force that does work to destroy
the building. The wrecking ball continues to swing back and forth as the crane is raised and
lowered. This allows the ball to keep hitting the building. Eventually, the wrecking ball hits
its target enough times to destroy the building.
Today, larger machines and special explosives are used to demolish buildings. Fewer people
use wrecking balls. Demolishing buildings with explosives is faster. It is more precise.
However, using explosives takes careful planning. It also requires more safety precautions
than do wrecking balls.
Today, wrecking balls are often used to remove structures in tight spaces. They are used on
smaller buildings where explosives should or cannot be used. Or, they are used to knock
buildings down to a height where explosives can be used safely.
