Answer 1

- Wood is bad at moving heat away.
- Metal moves heat from your hand fast.

Explanation: both spoons are at about room temperature, but metal has a much higher thermal conductivity, so it draws heat from your hand quickly and feels cold. Wood is a poor conductor, so much less heat is drawn and it doesn't feel cold.
