•
Natural Resources – Raw materials and
energy that we take from the natural
environment for human use.
Raw materials and energy obtained from the
environment for human use.
Original source of all goods.
Sustain human life.
Future generations will likely depend on the
same natural resources we depend on
today.
Can be renewable or nonrenewable.
Brainpop: Natural Resources
Renewable vs. Nonrenewable
• Renewable: can be made again, or renewed, by
nature.
• Some limited; some unlimited

Energy A - Z
Lesson 2
Energy A - Z
Energy in science is defined as the
capacity to do work or create change.
• We will NOT be focusing on energy
outside of our bodies. (No running, lifting,
etc..)
• We WILL be focusing on energy used to
power appliances or fuel vehicles.
Thinking Time . . .
• Discuss with your group:
– Look at the following four categories of energy use
– Which uses the most? Which uses the least? In box #2
rank the following categories: 1- 4 from most to least.
» Residential – electricity used in our homes
» Industrial – industry and manufacturing
» Commercial – stores and restaurants
» Transportation – personal and commercial
use of transportation
Now, Lets look at the next slide and find
out . . .
Transportation
27% includes
personal use of
cars, busses, trains,
or planes, as well
as transportation
related to
commerce and
industry.
Residential 22%
includes energy used in
our homes – electricity
for lights & electric
appliances; natural gas
for a furnace, stove, or
hot water.
Commercial 18%
includes commerce or
business and trade
such as stores or
restaurants where we
make purchases.
Industrial 33% includes industry and manufacturing, such as the energy needed
to make metals from raw ore, or plastic from oil, denim fabric from cotton, as well
as making cars, computers, or blue jeans with processed materials.
What was the most surprising fact
you learned?
What was the least surprising?
Write the information you learned about the
four categories of Energy usage in your
packets. Be sure to include the percentages.
Thinking Time . . .
• Discuss with your group:
What do you think is the percentage of
nonrenewable resources vs. the renewable
resources used in the United States.
example: 40% nonrenewable
60% renewable
As a group, decide upon a percentage.

Hmmmm . . .
Now, Lets look at the next slide and find
out . . .
What was the most surprising fact
you learned?
What was the least surprising?
Write the information you learned about the
four categories of Energy usage in your
packets. Be sure to include the percentages.
Thinking Time . . .
• Discuss with your group:
Which country uses the most energy and which
country uses the least – Rank the following
countries in the order of most (1) to least (13)
Energy consumption.
Kenya
India
Russia
Brazil
China
UK
Kuwait
Mexico
Iraq
United States Germany
Australia
Japan
The average Per Person Energy Use in the US is among the highest in the world!
Summary of your what you
learned today:
Make 4 Generalizations about your
learning today:
(not specific facts)
Making an inference about what
you learned.
• Example: We use energy in
many ways.
Energy Transformations
Lesson 3
Law of Conservation of Energy
or, Law of Thermodynamics
What do you think this means??
• Energy can be neither created nor
destroyed, it can only be transferred
from one form to another.
• Anytime we use energy for any purpose it
must be transformed from another source.
like natural resources from the
environment.
• We can always trace energy back to
natural resources.
Energy
• Majority of the current energy supply from
the US and other industrialized nations is
derived from nonrenewable sources.
• Consumer use of energy necessitates
converting energy from one form to
another
– Example:
• coal to electricity to light
• Natural gas to heat to stove
Energy Transformations
• Energy can be potential (stored) or kinetic
– Potential (stored) energy: energy that is stored
in some way
Brainpop: Potential energy
– Kinetic energy: energy of motion, involves
Brainpop:
movement of some kind
• Energy can be neither created nor
destroyed, but it can be transformed.
Kinetic
energy
– Light bulbs convert electric energy to light
energy
– Movement of our bodies converts chemical
energy to kinetic energy
– School bell converts electric energy to sound
energy
Brainpop: Forms of energy
Energy: The capacity to do work or create change
• Motion Energy
– The energy of an object
or substance in
movement; kinetic
energy
– Person dancing, car
moving, thrown ball
• Gravitational Energy
– The energy an object has
due to place or position,
such as its height above
the Earth; a form of
potential energy
– Rock on the edge of a
cliff, water behind a dam
• Electric Energy
– The energy of electrons
(negatively charged
particles) moving or
flowing within a
substance
– In power lines, from a
battery
• Light Energy
– The electromagnetic
energy that travels in
waves; radiant energy
– Sunlight, light of a lamp
or TV or computer
monitor
• Heat Energy
– The internal energy of a
substance due to random
vibration & movement of
atoms & molecules;
thermal energy
– Heat from stove, grill, fire
• Sound Energy
– The energy that moves
through substances (like
air) by compression
waves; sound
– Any kind of sound from a
human, machine, animal
• Chemical Energy
– The energy stored in
chemical bonds between
atoms & molecules
– Photosynthesis in plants,
eating food, coal, oil
• Nuclear Energy
– The energy stored in the
nucleus of an atom; holds
the atom together; atomic
energy
– Uranium at a nuclear
power plant; plutonium in
a nuclear bomb
Laws of Thermodynamics: Total amount of energy in the universe
is constant. Energy can be neither created nor destroyed, but it
can be transferred from one form to another.

Main Ideas
• With your group – put together your
facts/Main Ideas from the video to
come up with 3/4 different
facts/Main Ideas (one for each
person in your group)
• Put your initials next to the fact/Main
Idea that you contributed.
• Put all your names/period # on this
paper and turn it into the box.
• You have 5 minutes.
Energy & Electricity
• Electric energy can be made from many other
forms of energy.
• Electromagnetism is a natural phenomenon in
which electricity and magnetism affect each
other.
• Most ways of making electricity rely on
electromagnetism
• Most power plants make electricity with
turbine generators (which rely on
electromagnetism).
Answer the 3
questions on
the back of
your student
reading page.
Task:

highlight important information.
• 2. ANSWER QUESTIONS: Complete the question sheet:
Energy and Electricity together – each person should have their
own worksheet. Yes, write COMPLETE SENTENCES!
• 3. PICTURE & FLOW MAP: On the back of the question sheet,
draw a picture of a Turbine Generator. Then create a Flow Map
showing how a Turbine Generator works. You may work
together, however, each person is to have their own Question
