Natural Resources Do it All

• Lesson 1

4
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.

Renewable vs. Nonrenewable

• Renewable can be made again, or renewed, by
  nature.
• Some limited some unlimited
• Heat of the Earth (geothermal)
• Biomass (plants, trees, crops, animal wastes)
• Movement of water (hydropower)
• Wind
• Sun/Solar radiation
• Nonrenewable Cannot be made again by nature
• Limited amount
• Fossil fuels (coal, oil, natural gas)
• Nuclear or atomic energy (stored in nucleus of an
  atom)

Energy A - Z

• Lesson 2

9
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.

10
Thinking Time . . .

• Discuss with your group
• Look at the following four categories of energy
  use
• Which uses the most? Which uses the least? 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 . . .

11
Residential 22 includes energy used in our
homes electricity for lights electric
appliances natural gas for a furnace, stove, or
hot water.
Transportation 27 includes personal use of cars,
busses, trains, or planes, as well as
transportation related to commerce and industry.
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.
13
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

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 Irag
• United States Germany
• Australia Japan

17
The average Per Person Energy Use in the US is
among the highest in the world!
18
Summary

• We use energy in many ways!
• In addition to energy we use directly, energy is
  being used on our behalf by business, industry,
  and transportation systems around the world.
• Because energy is important in our lives and
  because energy accounts for a major portion of
  our impacts on the environment, we need to
  understand and think about our energy use.
• Conserving energy and relying more on renewable
  energy sources will lessen our impact on the
  environment.

Energy Transformations

• Lesson 3

21
Law of Conservation of EnergyWhat 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.

22
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

23
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
  movement of some kind
• Energy can be neither created nor destroyed, but
  it can be transformed.
• 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

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

25

• 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

• 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

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.

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).
