Question: How are spent nuclear fuel rods usually disposed of?
HW: Finish Nuclear Energy Classwork (Six Terms- P.p. 264-70)
Today we will investigate Sec. 2 (Nuclear Energy)
Below are the key points we will focus on with this section:
Phy. Sci. Energy Sources Key Terms 4/29/13 Mr. Smith
1. The Process of Nuclear Energy (264)
We call the process fission, where an extremely small amount of mass is converted into an enormous amount of energy. As we saw in last week's movie, neutrons strike a nucleus of a uranium 235 atom, and the nucleus splits apart, releasing neutrons (and a lot of energy).
2. A nuclear Reactor contains… (264)
a fuel that can be made to undergo nuclear fission; they contain control rods that are used to control the nuclear reactions; and they have a cooling system that keeps the reactor from being damaged by the heat produced.
3. Nuclear Fission (266): During fission - which I described in q. # 1, nuclear chain reactions occur and the number of nuclei that split multiply very quickly, creating a tremendous amount of thermal energy to use to turn the turbine to generate electricity.
4. “The Thermal Energy is Released…” (267)
5. “The Risks” (267)
6. Fusion (270)
Homework: Re-read p.p. 264-270 or Monday's homework
Today we will review Monday's key terms involving fossil fuels. Per. 1 and 2 classes will finish the H2O balloon catapult activity.
Ch. 9 Key Ideas:
1. Energy cannot be created or destroyed...
2. Fossil Fuels- Decayed remains of ancient plants and animals
3. Burning fossil fuels converts energy from chemical bonds to heat and
4. Chemical energy in fossil fuels are more concentrated...
5. Petroleum- Thick, greenish-brown, highly flammable liquid formed by
decayed ancient organisms.
6. Fractional distillation- The heating of crude oil in order to separate the
compounds in petroleum.
7. Petroleum is used for plastics...
8. Natural gas- Originates from decayed ancient* organisms, has more
energy than oil or coal, burns more cleanly, and provides about 1/4* of
the energy consumed int the United States.
9. Electricity is generated when fossil fuels are burned. The burned fuel
releases thermal energy, which produces high pressure steam, which
spins a turbine, which produces an electric current, which is
transmitted through power lines to you and me.
10. Only about 35% of the energy in fossil fuel reaches us since some
energy is lost in every stage of the process.
11. Fossil fuels pollute.
12. Mining coal can cause health problems for miners.
13. Fossil fuels are nonrenewable resources, so it's important not to
Homework: Read p.p. 271-276, then define the five highlighted terms

Thursday, March 21
Homework: Read p.p. 166 and 167, and bring a spoon and a cup to class.
Today's focus is convection and radiation.
Below are the current quizlet terms to know:
Temperature (158, 9) the average kinetic energy of the individual particles; the measure of how hot or cold something is.
Thermal energy: (159) The total kinetic and potential energy of all the particles in a substance.
Why does increasing the temperature of an object increase its thermal energy? (159) It increases the kinetic energy of the particles.
Why would a puddle of water have less thermal energy than a pond when they both have the same temperature? (160) Because there are thousands and thousands of times more H20 molecules (particles) in a pond, and each of those molecules have their own kinetic energy.
Heat: A form of energy that is transferred by a difference in temperature. The thermal energy that flows from something at a higher temperature to something at a lower temperature. (160)
Conduction: The transfer of thermal energy from one substance to another through direct contact. (164)
Convection: The transfer of thermal energy by the circulation or movement of a fluid by the movement of warmer and cooler fluids from place to place. (165) Radiation Thermal energy that is transferred in the form of rays or waves or particles. (167)

· What has greater t.e., a pot of boiling water or an iceberg? Explain.
· Name two examples of conduction:
· Name two examples of ‘work to heat’
· Sun on your skin and the warmth of a fire are two examples of…
· Three main types of heat transfer: C.C.R.
· A heater and boiling water are two examples of…
· How does the high specific heat of water affect our local climate?
Today we will take our thermal energy exam
Do Now: Why do water droplets appear on the sides of a chilly can of Dr Pepper?
Ans.: The air is loaded with water - in the gas phase. We don't see it because the water particles are teeny-tiny and far apart. The water particles are moving fast-n-far apart. But... when the H20 particles fly past something cold, they come together and condense, and turn into these teeny tiny water droplets we see on the side of the chilly can of Dr Pepper.
Today we will begin our solar energy movie and finish it on monday.
Homework: Read p.p. 256-9 (optional), Test signed and corrected by friday.
Today We will Review Last week's test answers, plus continue our solar energy movie.
Question of the day: How do the walls of the ice cream machine help make the ice cream?
Answer: Heat travels naturally from warmer to cooler areas, and the cooler walls of the ice cream maker pull heat out of the warmer milk and cream, changing it to the solid phase. Voila!
(last friday's question involved how droplets appear on the sides of a chilly dr pepper)
Homework: Remember to read p.p. 256-259 by Friday, and have your test signed and corrected by friday, too.
Today is the start of our state exams, so fifth and eighth period classes will see me today.
We will finish our solar energy movie and preview our new chapter involving fossil fuels.

Today students will record "phy. sci. big ideas" notes from the year from the white board while i check test signed and corrected. we will review pg. 259, and then launch h2o balloons.
HW: Finish Fossil Fuels Classwork
Today we will watch a short video about how coal is
formed, and then you will have time to answer the
homework questions below. Here is the link to today's
seven minute movie:
Monday, April 22, 2013 (Every day is _______ Day)
1. Energy- An ____________ to do work; to cause ______________
2. Fossil Fuel- F. fuels are formed from the decaying remains of
ancient (2-350 m.y.a.) plant and animal remains.
Petroleum (oil), natural gas, and coal are f. fuels.
(Just so you know!)
3. How are fossil fuels different than wood? (257)
Wood is renewable (can be replaced in less than 30 years);
fossil fuels can take millions of years to replace. Fossil fuels
are much more concentrated with chemical potential energy
4. How is oil and natural gas formed? (258)
Natural gas is mostly methane (!), and it rises to the top of the
petroleum deposits. The sediments sitting above dead marine
organisms create pressure, heat and chemical reactions over
millions of years.
5. How is coal formed? (258, 260)
Usually from swampy vegetation, layers of sediment cause an
increase of pressure and temperature over millions of years.
6. Petroleum (260)
It's oil. It's a highly flammable liquid formed from decayed ancient
organisms such as microscopic algae and plankton.
7. What is fractional distillation?
Fractional distillation is simply the heating of crude oil at refineries
in order to separate the many compounds of oils.
8. Identify four objects in the classroom that are made from petroleum.
Rubberbands, plastic bottles, California slingshots, and the bottom
of my shoe.
9. Natural Gas
Natural gas is composed mostly of methane (CH4), which rises to
the top of the petroleum deposits. Propane is a natural gas, too.
10. Nonrenewable Resource
Fossil fuels are categorized as nonrenewable because they cannot
be replaced easily or as quickly as they are used. Solar and wind
energy are renewable because they do not take millions of years
to replace. Voila.
Homework: Review this week's work, and visit Quizlet throughout the
