Thermal Conductivity Bar

Comprises four metal strips made of different materials, namely copper, aluminium, brass and steel / iron, on a sturdy plastic frame.

Each metal strip has a sensitive strip attached which changes colour as its temperature changes. A simple experiment of Immersing this apparatus in a beaker of hot water will be able to clearly demonstrates how different metals conduct heat at a different rate. Students will be able to see clearly why some metals are a better conductor of heat than the other.
