  1. ENERGY TRANSFORMATIONS http://www.youtube.com/watch?v=5vJCOdFqiYg Bill Nye – Forms of Energy

  2. KEY UNDERSTANDINGS • Energy cannot be created or destroyed. (Turn & Talk) • Energy can be transformed from one type of energy to another.

  3. What is the source for most energy on Earth?

  4. THE SUN!

  5. What are the most common forms of energy? • Chemical • Electrical • Sound • Nuclear • Thermal • Light (radiant)

  6. Where does energy go? • Remember the law of conservation of energy!

  7. Energy is TRANSFORMED from one form of energy to another! • With your group can you guess some examples of energy transformations.

  8. What is the difference between potential and kinetic energy?

  9. Potential Energy is stored energy!! (not yet moving) • Kinetic energy is energy in motion!

  10. How Heat is Transferred Heat is transferred in 3 ways: • Conduction • Convection • Radiation

  11. Conduction vs. Convection • Conduction • Heat is transferred through direct contact (touch) Examples: • Touching a hot stove • Convection • Heat is transferred through circulation within a liquid or gas Examples: • Hot chocolate melting marshmallows

  12. Create a foldable! Create a foldable for the 3 types of thermal energy • Conduction • Convection • Radiation http://www.wisc-online.com/Objects/heattransfer/default.aspx
