The student places one end of each rod into a beaker of boiling water.
After a few minutes, the student touches the ends not in the boiling water.

The aluminum rod feels cooler than the plastic rod because aluminum is a better thermal conductor than plastic.
The plastic rod feels hotter than the aluminum rod because plastic is a better thermal conductor than aluminum.
The plastic rod feels cooler than the aluminum rod because plastic is a better thermal conductor than aluminum.
