This thermal conductivity bar set is ideal for demonstrating heat transfer in science lessons, helping students observe and compare how different metals conduct heat. Designed for use in secondary and college classrooms, it supports hands-on learning in physics.

• Includes four metal bars: copper, aluminium, brass, and steel

• Each bar fitted with a liquid crystal temperature strip that changes colour between 33°C and 45°C

• Conductivity values clearly marked on the back of the rigid plastic carrier

• Carrier keeps bars securely aligned for easy handling and observation

• Suitable for practical demonstrations of thermal conduction
