Transcript of 5th Grade Ch 10 lesson 1 what are nonrenewable energy resources
Ch. 10 Lesson 1What are nonrenewable
energy resources?
resource
supply that will meet a need for
materials or energy2 types
1. renewable
2.nonrenewable
1. renewable
can be replaced
ex: trees
2. nonrenewable
cannot be replaced or cannot be replaced as fast as we use it
fossil fuelscoal, petroleum (crude oil), natural gas
Natural Resources [07:06]
The energy from fossil The energy from fossil fuels comes from fuels comes from
sunlight.sunlight.
coal1. forms from swampy plants
2. layers of dead plants build up
3. decaying material forms peat
4. peat gets buried
5. soft coal hard coal
• releases sunlight energy from plants
• fuels most electric power plants
Many U.S. coal beds are very near the ground's surface, and about
two-thirds of coal production comes from surface mines.
Chocolate chip mining
• Coal is extracted from the Earth’s crust through a process called mining.
• Once mining engineers have discovered, extracted and prepared the coal, they can be used to make energy.
Chocolate chip mining
Cookie # of chocolate chips on the surface of the cookie
Predict how many choc. chips you can extract

Instructions
1. Take one cookie and pretend it is an environment in which a great source of energy (coal) has been located (chocolate chips).
2. Predict how many chips you can extract from this environment.
Instructions3. Using your mining tools
(toothpicks), extract as many chips as possible before your mining lease expires (in 2 minutes) and pile them to one side.
4. Count the chips you recovered and compare this with the number of chips you predicted.
Instructions
5. Now study the impact of your mining on your "cookie" environment. What do you think would happen if this were a real coal mine? What if animals and plants lived above the coal deposits? What might happen to them after the mining has taken place?
6. Now think of ways to mine the second cookie with less damage to the environment.
Instructions
7. Take the second cookie and mine it using the ideas you came up with to protect the cookie environment. Pile the new chips to one side.
8. Compare the two piles of chips. How did you do the second time?
petroleum (crude oil)found beneath land or ocean
formed same as coal except buried tiny sea organisms instead of plants
natural gasoften found by crude oil
(petroleum)
type of energy
description 2 advantages 2
dis-advantages
fossil fuels
made from the remains of organisms
1. easy to store & transport
2. more energy than other resources
1. supplies are limited
2. cause pollution
Fossil Fuels [00:51]
Fossil fuels are made from the remains of organisms.
Fossil fuel is easy to store.
Fossil fuel is easy to transport.
The supplie
s of fossil fuels are
limited.
Fossil fuels can cause pollution.
resource• supply that will meet a need for materials or energy
renewable & nonrenewable
• 2 types of resources
renewable
• resource that can be replaced
nonrenewable
• resource that cannot be replaced
nonrenewable
• resource that cannot be replaced as fast as we use it
coal• formed from plants
coal• fuels most electric power
plants
fossil fuels• made from the remains of
organisms
petroleum (crude oil)• made from the remains of buried tiny sea organisms
coal• formed from peat
List 2 advantages of fossil fuels.
Fossil fuel is easy to store.
Fossil fuel is easy to transport.
List 2 disadvantages of
fossil fuels.
The supplie
s of fossil fuels are
limited.
Fossil fuels can cause pollution.
