Worked Solution

Step 1: The base needs to transfer heat to the food (needs a good conductor). Step 2: The handle needs to stay cool for safety (needs a poor conductor/insulator). Step 3: Metal conducts heat well; wood/plastic do not.

Correct answer: Metal is a good conductor of heat; wood is a poor conductor.
