Why the Metal Gate Feels Colder Than the Fence

On a chilly morning, Mina touched the metal gate at the park. It felt very cold. Then she touched the wooden fence beside it. The wood felt much warmer. Mina wondered why.

The gate and the fence were really the same temperature. They had both sat in the same cool air all night. The difference is in how they move heat.

Heat always flows from a warm thing to a cooler thing. Your hand is warm, so heat flows out of it when you touch something cooler. Metal is very good at carrying heat away. It pulls heat out of your hand fast, so your skin senses cold.

Wood is a poor carrier of heat. It pulls heat from your hand slowly. Your hand stays warmer, and the wood feels less cold.

So the cold feeling is not just about the gate. It is about how quickly heat leaves your hand. That is also why a metal spoon in hot soup gets hot so fast.

It was a chilly morning. Mina touched the metal gate at the park. It felt very cold. Then she touched the wood fence. The wood felt warmer. Why?

The gate and the fence were the same temperature. They sat in the same cool air all night. The difference is how they move heat.

Heat goes from a warm thing to a cooler thing. Your hand is warm. So heat goes out of your hand when you touch something cooler. Metal carries heat away fast. Your skin feels cold.

Wood carries heat away slowly. Your hand stays warm. The wood feels less cold.

So the cold feeling is about how fast heat leaves your hand. A metal spoon in hot soup gets hot fast for this reason.

On a chilly morning at the park, Mina reached out and touched the metal gate. It felt startlingly cold. Next she touched the wooden fence beside it, and the wood felt much warmer. Mina wondered what could explain the difference.

In reality, the gate and the fence were exactly the same temperature, because both had sat in the same cool air throughout the night. The difference lies in the way each material moves heat.

Heat always flows from a warm object toward a cooler one. Since your hand is warm, heat leaves it whenever you touch something cooler. Metal is extremely good at carrying heat away, so it draws the heat out of your hand quickly, and your skin senses cold.

Wood, on the other hand, is a poor carrier of heat. It draws warmth out of your hand only slowly, so your hand stays warmer and the wood feels less cold.

The cold feeling, therefore, depends less on the gate itself than on how quickly heat escapes from your hand. This is also the reason a metal spoon resting in hot soup becomes hot so fast.

Ideas for class

  • Before reading, put chilly, temperature, metal, carrier and flow on the board with their meanings from the Words to know section and have students predict what the text will be about.
  • Read it aloud once while students follow along, then have them reread it alone or with a partner. At a calm 100 words a minute it takes about 2 minutes to read aloud.
  • Use the Read it big button (or B) to put the text on the projector, and Show answer on one question at a time so the class commits to an answer first.
  • Question 5 asks the reader to infer. Ask students to point to the words in the passage that led them to their answer.
  • Ask students to write one question the passage did not answer, then look for the answer in a book or on a classroom screen.
  • Print the student copy for independent work and keep the answer-key copy for yourself.
