Cylinder, Wood & Metal – Demonstration Rod for Heat Transfer (KS3+)

The Wood & Metal Cylinder is a simple yet highly effective demonstration tool for teaching heat transfer and thermal conductivity in school science lessons. This high‑quality cylindrical rod is divided into two halves—one made of metal and the other of wood—allowing students to clearly observe how different materials respond to heat.

When a sheet of paper is wrapped tightly around the cylinder and the rod is briefly passed through a Bunsen flame, the contrasting thermal properties become instantly visible. The section of paper touching the wood quickly scorches, while the section against the metal remains unburned, providing a memorable and visually striking illustration of heat conduction.

Measuring 200mm in length with a 30mm diameter, this model is ideal for classroom demonstrations, teacher-led explanations, and practical discussions in physics and general science lessons.

Ideal for School Science Lessons & Demonstrations

This Wood & Metal Cylinder is perfect for introducing and reinforcing core concepts in thermal energy transfer across KS3, GCSE, and A‑Level physics. It provides a clear, practical way to help students understand why some materials heat up quickly while others do not.

• Explaining heat transfer by conduction
• Comparing the thermal properties of metals vs. insulators
• Supporting discussions on material selection and engineering
• Enhancing demonstrations on energy transfer in everyday life
• Helping students understand why metal stays cooler than wood in a flame

Engaging, reliable, and simple to use, this demonstration cylinder provides a memorable way for students to explore thermal conductivity and deepen their understanding of heat transfer principles.
