DESCRIPTION
Energy Terms. Renewable Energy Energy sources that can be replaced, or replenished. News. Yesterday, scientists finished decoding the DNA of a Wooly Mammoth. Not used to make one with cloning, but instead used to understand how elephants have evolved. News. - PowerPoint PPT PresentationTRANSCRIPT
NewsNews• Yesterday, scientists finished decoding the DNA of a Wooly Mammoth.
• Not used to make one with cloning, but instead used to understand how elephants have evolved.
NewsNews• NASA is celebrating 10 years of the International Space Station.
• 167 visitors, from 15 countries.
• New Shuttles by 2010, retire the current ones! Obama

Photovoltaic-
Electricity being made by converting Sunlight/Visible Light.
Solar Panels
Energy TermsEnergy Terms
Fossil Fuels•Ancient Stored Sunlight•Coal, Oil, Natural Gas•Considered the Catalyst for Accelerated Global Warming
Energy TermsEnergy TermsCoal-
Energy Source made of preserved swamp ecosystems. Water/Mud preserved. Largest world-wide energy source for producing electricity
Energy TermsEnergy Terms
Oil-Petroleum
Naturally occurring liquid found in Earth, comprised of ancient Zooplankton and Algae, hydrocarbons(oceans)
Energy TermsEnergy Terms
Natural Gas
-Source of energy from swamps, marshes and landfills. Ancient to recent. Bondies Island
Energy TermsEnergy Terms
Nuclear Power Plants
-Energy produced by splitting atoms and using the heat to make steam and spin turbines
Energy TermsEnergy Terms
Unsure?!
These energy sources have potential to be either renewable or non-renewable
HomeworkHomework
Hydrogen
-Energy stored in the attractive bonds of Hydrogen gas. H2 want to be in a water state.
Energy TermEnergy Term
Conservation of energy-
Law- Energy can neither be destroyed or created. All energy must be accounted for
Thermal EnergyThermal Energy• Total amount of Kinetic Energy from Particles. As Kinetic Energy of particles increases, so does the Thermal energy.(Heat Energy) The particles move faster.
Energy TransferEnergy TransferHeat-Movement of Thermal energy from a substance at a higher temperature to another at a lower temperature
Energy TransferEnergy Transfer
Conduction-Transfer of Thermal Energy, without particles moving. Transfer by touching, Direct Contact
Transfer of EnergyTransfer of Energy
Convection-
The transfer of energy by movement of Fluids. Earths mantle as well as water in a pot on the stove.
Energy TransferEnergy Transfer
Radiation-Transfer of energy by or through EM Waves (Electromagnetic). Sun’s rays, hot lamps, tanning salon.

Bell Work #1Bell Work #1How would you
Describe a Solid?
•Packed together tightly in relatively fixed positions. Can Vibrate!
Bell Work #2Bell Work #2How would you Describe a Gas?
•Moving so fast that they do not stay close to one another. Expand to fill space!
Bell Work #3Bell Work #3How would you
Describe a Liquid? • Particles held together, but not so tightly that they can’t move past one another. No Shape, but Volume!
Energy TermsEnergy Terms• Insulator-
Nature of material and it’s particles is resistant to absorbing Kinetic Energy
