Lesson 2.01: Potential and Kinetic Energy
Lesson Page:
There are two basic types of energy, ________________ and ________________.
Kinetic Energy
Kinetic energy is the energy of _______________. Any object that is moving has
kinetic energy. The faster an object travels, the ___________ kinetic energy it has.
Examples of kinetic energy: throwing a baseball or jogging.
Potential Energy
Potential energy is also referred to as _____________ energy. It is more formally
called the energy of __________________.
Potential energy is converted into kinetic energy when an object has a _________
acting upon it.
Objects that are higher off the ground have __________ potential energy.
Example of potential energy: the energy stored in chemicals and atoms. This type
of potential energy can be seen in a nuclear __________ ___________.
Assignment Due: There is nothing to turn into your teacher for this lesson.
Lesson 2.02: Law of Conservation of Energy
Lesson Page:
When you are holding a rubber band in your hand, not stretching it yet, what type
of energy is stored in your body? (circle one) POTENTIAL or KINETIC
During the act of stretching the rubber band back, what type of energy are you
using? (circle one) POTENTIAL or KINETIC
While holding the stretched rubber band back, and holding it still, what type of
energy is stored in the rubber band? (circle one) POTENTIAL or KINETIC
Once you let go of the rubber band, it will fly through the air. What type of energy
does the rubber band have while it is moving? (circle one) POTENTIAL or KINETIC
Energy Transformations
Ice cream to bike - When eaten, the chemical energy in the ice cream cone
transforms into ___________________ energy for riding the bike.
Plug to stove - Electrical energy from the plug transforms into ________________
energy in the stove when it is heated.
Sun to tree - Radiant energy from the sun transforms into _________________
energy in the tree when it produces food.
Atom to laptop - Nuclear energy in the atom transforms into _________________
energy to run the laptop.
Battery to mp3 player - Chemical energy in the battery transforms into _________
energy when listening to the mp3 Player.
Assignment Due: For this lesson you will create two of your own original
examples of how energy flows and is transformed from one type to another.
Lesson 2.03: Energy Conversion Activity
Lesson Page:
The Law of Conservation of Energy says that energy cannot be created nor
___________________, but it can be transformed from one form to another.
In other words, all of the energy available at the start of a transformation still
exists in some form of energy after the change is complete. Energy isn’t just
created out of nowhere, and doesn’t disappear! It is just “recycled” in a way.
The Law of Conservation of Energy Demonstrated in a Roller Coaster:
1. Electric energy from a motor is converted into _______________________
energy as the chain pulls the roller coaster up the first hill. The higher the
roller coaster goes, the higher potential energy is.
2. As the roller coaster travels down the hill, potential energy is converted
into mechanical __________________ energy.
3. As the roller coaster travels across the track, some of the kinetic energy is
converted into ___________ because of the friction between the coaster
and the track.

Lesson 2.04: Heat Transfer
Lesson Page:
Heat is also called ____________________ energy.
Thermal energy looks for all things to be fair. This means that thermal energy
moves from an area with a higher amount of thermal energy to an area where
there is less thermal energy. We call this process _________ ______________.
Three Ways Heat Can Be Transferred: Conduction, Convection, and Radiation
Conduction
Convection
Radiation
Definition: When two
objects ____________
each other
Definition: When heat
moves through the air or
a ______________
Definition: When heat
moves through
____________________
waves (light)
Explanation: When two
objects touch, heat is
always transferred from
the __________ object to
the __________ object.
Explanation: Only
happens in liquids and
gasses; causes circulation
and movement of the
____________________
Explanation: Heat is
transferred through
______________ or
electromagnetic waves,
not by touch or fluids.
Examples: Cooking on a
grill; touching a hot piece
of metal
Examples: Boiling water
in a pot; currents in the
ocean
Examples: The sun gives
you a sunburn; using an
electric heater

We have already learned that solids conduct heat better than liquids or gases;
however, not all solids are as good at conducting ____________.
A substance that is good at conducting heat is called a ____________________.
Examples: metals like steel, aluminum, and copper
A substance that is not good at conducting heat is called an _________________.
Examples: wood, Styrofoam, cloth, plastic, oven mitts

Lesson 2.06: Nonrenewable Energy
Lesson Page:
Energy is very important in our lives! Every day, we use the Law of Conservation
of Energy. We constantly convert potential energy into ______________ energy.
Some examples: Using potential energy stored in gas to heat our homes,
using potential energy stored in coal to get electricity, and using potential
energy stored in _______________ when we drive our cars.

Nonrenewable energy is energy that eventually __________ _________.
Three examples of nonrenewable energy sources are:
 __________
 ____________
 ____________________ ________
Fossil Fuels
Oil, coal, and natural gas are called fossil fuels!
Fossil fuels are made from dead plants and animals that were buried in the
ground _________________ of years ago. Unfortunately, humans are using up
fossil fuels faster than they are re-forming.
One major problem with fossil fuels is that they produce ____________________.
