Grade Level: 5th - 6th; Type: Physics


In this experiment students will find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

Research Questions:

  • What are the advantages of cast iron pans? Teflon?
  • What are some applications of both kinds of pans?


  • Cast iron pan
  • Regular teflon pan of the same size
  • Cooking thermometer
  • Timer
  • Pen and paper for notes

Experimental Procedure

  1. Attach the probe of a cooking thermometer onto the surface of the pan.
  2. Turn on the to medium heat for both pans.
  3. Observe which pan is heating up faster.
  4. Turn off the heat and watch as the temperature drops. Which pan has a faster-dropping temperature?
  5. Record your results.
