Guess how much the Eiffel Tower grows in the heat, then warm your own tower.

Lesson Plan

Explore proportional relationships and the constant of proportionality through thermal expansion.

  1. Question: Ask what students spot and what they are curious about. Read “How much would the tower grow?” aloud. Have each student guess and say why.

  2. Question: Read “Which way does the top lean?” aloud. Have partners explain their guesses to each other.

  3. Real-world application: Ask: Where else have you seen this?

  4. Your turn: Have students try their own. Ask them to predict before they test.

How to run it
