Student Friendly Objective(s): Lesson Essential Question(s): How does population growth affect an ecosystem? Data Analysis:   Materials: Worksheets for Interactive Notebook and Independent Practice

Answer the following questions: How are these two videos different? Write down 3 things the video says about fracking. http://www.youtube.com/watch?v=dZe1AeH0Qz8 Write down 3 things this video says about fracking. http://www.youtube.com/watch?v=Y1W8MnveFq8 Answer the following questions: How are these two videos different? What do you think is the purpose of each video? How does the maker of each video affect its message?

What is energy? then…what is work? The ability to do work. Force and movement. Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

How is energy transferred? Energy can change from one type of energy to another, but it cannot be destroyed. http://www.youtube.com/watch?v=Dw50SCHEzOM (0:00- 0:26) http://www.youtube.com/watch?v=btLU2lb3-xs (0:38- 2:57) Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

How do power plants produce energy? The energy source spins a turbine, which spins the rotor. That rotor causes a stream of electrons which are captured and can be sent along transformers.

How are traditional energy resources attained? Wood Trees are harvested by cutting down forests. Cut trees are then processed to create lumber for fuel, construction, and consumer use.

Surface mining: (40% of production) Coal Mining Surface mining: (40% of production) Explosives are used to break up soil and rock Coal is drilled, fractured, and mixed in strips Coal is loaded onto trucks Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Coal Mining Underground mining: (60% of production) Coal is mined by cutting a network of “rooms” into the coal sea “Pillars” of coal are left behind to support the roof of the mine

Uranium Mining Open-pit removal: Explosives are used to break up rock Uranium ore is removed, then transported for further processing Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Uranium Mining Underground mining: Miners use shafts to move equipment and workers throughout the mine In-situ recovery: Solutions are injected into the ore through pipes Miners separate uranium from the rock and pump the solution to the surface All uranium ore must be processed into a finished product: uranium powder (yellowcake)

Oil Massive rigs pump out oil up to the ground for processing A hole is drilled in the ground above an oil deposit A steel pipe is drilled down to the reservoir rock where oil is found Massive rigs pump out oil up to the ground for processing Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Natural Gas Fracking: Fracking fluid is pressure injected into the ground through a drilled pipeline The fluid hits the rock at a high pressure and causes the rock to crack This creates fissures (holes) where natural gas flows into the well Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Nuclear Fission Uranium-235 is mined from the ground A reactor fires a neutron at a U-235 nucleus The nucleus absorbs the neutron, becomes unstable, and splits Releases massive amounts of energy Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

What are the effects of using traditional energy? Wood Leads to deforestation fewer trees leads to more CO2 Smoke from fires decreases air quality Energy inefficient Coal Mining Coal contributes 31% of all CO2 Nonrenewable Coal burning lowers air quality Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Uranium Mining Oil Cancer risks to miners due to radiation May contaminate local drinking water sources Nuclear waste is toxic Oil Nonrenewable Burning oil releases greenhouse gases Oil leaks may occur, causing environmental disasters Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Chemicals contaminate nearby groundwater Requires lots of water Natural Gas Chemicals contaminate nearby groundwater Requires lots of water Releases more emissions than coal Has been linked to earthquakes Nuclear Fission Highly radioactive waste Waste must be stored for thousands of years Risk of meltdown Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes
