  3. What is energy? • The ability to cause a change in matter • Through movement • The ability to do work • Energy cannot be created or destroyed, but it does change forms

  4. Ways to Classify Energy • 1. Solar, Light, Chemical, Mechanical, Electric, Sound, Heat, and Magnetic

  5. Answer Now :20 21 of 26 Which of the following show energy? • Bird flying through the sky • Human sleeping in bed • Bottle sitting on the counter • 1 and 2 only • All of the above

  6. Solar Energy • Solar-from the sun • Examples-solar panels

  7. Light Energy • Light-energy from the sun that we see • Examples-lamps, flashlights

  8. Chemical Energy • Chemical-energy stored in another substance • Ex-batteries, fuels

  9. Mechanical Energy • Mechanical-combination of potential and kinetic energy (muscle power) • Examples-winding up a toy

  10. Electric Energy • Electric-energy from an electric current • Examples-television, dvd player

  11. Sound Energy • Sound-energy we hear • Examples-music, talking

  12. Heat (thermal) Energy • Heat-energy that is given off (can be hot or cold) • Examples-fire, snow
