Quick and easy tools for demonstrating thermal expansion. There are four bar combinations: Brass/Aluminum, Brass/Iron, Copper/Iron, and Brass/ Copper. Since each metal has a different coefficient of thermal expansion, they will create a unique curve when paired with a different metal. Metal bars are stamped with the identification of each metal, Aluminum (Al), Iron (Fe), Copper (Cu). The Brass bar is not stamped. Includes activity guide.
