  1. Solar Ovens By: Juan Gomez Perry Francois-Edwards Luis Perez

  2. Outline • Intro • Insulators • Hypothesis • 3 Modes of Heat Transfer • Procedure • Results • Conclusion

  3. Introduction • Project Theme: thermal energy/energy transfer • Built a solar oven using 3 insulators: • Cotton • Styrofoam • Newspaper

  4. Insulators • A material that does not allow energy transfer • For our experiment, the insulator kept the heat inside the box Thermal Conductivities: • Cotton balls: 0.030 W/m-K • Newspaper: 0.050 W/m-K • Styrofoam: 0.033 W/m-K

  5. Hypothesis • Theinsulator with the lowest value of thermal conductivity would be the most efficient insulator • Cotton should win!

  6. Heat Transfer • Energy in the form of heat • Conduction • Convection • Radiation

  7. Conduction • The heat transfer that occurs when a temperature difference exists in a stationary medium

  8. Convection • The heat transfer between a surface and a moving fluid that are different temperatures

  9. Radiation • The heat transfer of all surfaces of finite temperature emitted in the form of electromagnetic waves

  10. Materials • Pizza boxes • Aluminum foil • Black foam board • Plastic Wrap • Tape • Glue • Knives • Scissors • Sticks • Thermometers • Insulators • Ingredients for S’mores

  11. Procedure

  12. Results

  13. Results

  14. Conclusions • Because cotton had the lowest thermal conductivity, it was the most effective insulator.
