for use in Arizona

Brainpop: Energy Sources

Natural Resources Do it All

Lesson 1

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

– 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)

Brainpop: Fossil Fuels

Natural Resources Are Us• Find & lay in a line the following 7 final products:

– 1. Books– 2. jeans– 3. soda can– 4. drum & guitar– 5. computer CPU– 6. copper pipe & wire– 7. backpack

• Line up the rest of the cards under each final product to show the order in which the product was made.

• There 3 cards that go with each final product• Example: Plastic Bottle plastic processed oil or

petroleum oil well

Natural Resources: Answers• Books

– Paper– Logs– Trees/sun, soil, water

• Jeans– Denim fabric– Cotton bolls– Cotton plants/ sun, soil

water

• Soda Can– Sheets of aluminum– Aluminum ingots– Bauxite mine

• Drum & Guitar– Partially made instruments– Hardwood planks– Hardwood trees/sun, soil, water

• Computer CPU– Circuit board– Silicon (Si)– Silicon mine

• Copper Pipe & Wire– Processed copper– Copper ore– Copper mine

• Backpack– Nylon fabric & thread– Processed oil/petroleum– Oil well

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 . . .

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.

Transportation 27% includes personal use of cars, busses, trains, or planes, as well as transportation related to commerce and industry.

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!

Making an inference about what you learned.

•Example: We use energy in many ways.

Energy Transformations

Lesson 3

Law of Conservation of Energyor, 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 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

Brainpop: Kinetic 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

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.

• 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
