Bell Ringer: None, turn in folders

    • Notes on efficiency

      • Ratio of how much energy gets to the form we want it in

      • Usually expressed as a percent

    • Notes on Energy flow diagrams

      • Visual way to show the path of energy

      • Diagrams ALWAYS branch out because there are no 100% efficient processes

      • Diagrams can always be traced back to energy from the sun

  • Homework: Make an energy flow diagram for Tom Hanks making fire in the the movie "Cast Away"
