Science project
Cast Iron Pans Versus Regular Teflon Pans
Grade Level: 5th - 6th; Type: Physics
Objective:
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?
Materials:
- Cast iron pan
- Regular teflon pan of the same size
- Cooking thermometer
- Timer
- Pen and paper for notes
Experimental Procedure:
- Attach the probe of a cooking thermometer onto the surface of the pan.
- Turn on the to medium heat for both pans.
- Observe which pan is heating up faster.
- Turn off the heat and watch as the temperature drops. Which pan has a faster-dropping temperature?
- Record your results.
Terms/Concepts: Cast iron; Teflon; Temperature; Heat
