Bimetallic Strip with Wooden Handle – 200 × 15mm (KS3+ Demonstration Tool)

This high‑quality Bimetallic Strip is designed specifically for KS3 and above, providing a clear and engaging demonstration of differential thermal expansion. Constructed from a bonded strip of brass and steel, it reliably curves when heated, showing how two metals expand at different rates.

The 200 × 15mm strip is securely riveted with heat‑resistant fixings and mounted into a w well‑finished wooden handle for safe classroom use. Ideal for physics lessons exploring heat, energy transfer, and material behaviour.

Key Features

• Durable bimetallic strip made from brass and steel
• Demonstrates differential expansion when heated
• Strip size: 200 × 15mm
• Strong, heat‑resistant rivets secure the metals together
• Mounted in a smooth, well‑finished wooden handle for safe handling
• Suitable for KS3, GCSE, and A‑Level physics

Ideal for School Science Lessons & Physics Demonstrations

Perfect for introducing or reinforcing the concept of thermal expansion, this bimetallic strip provides a clear visual demonstration for students at all secondary levels. It is especially useful for:

• Explaining how different metals expand at different rates
• Demonstrating energy transfer and heating effects
• Exploring the science behind thermostats, switches, and sensors
• Supporting practical teaching of materials, particles, and temperature
• Safe, hands‑on demonstrations using a heat source such as a Bunsen burner

Robust, simple to use, and highly effective for visual learning, this Bimetallic Strip is an essential demonstration tool for physics classrooms and school science labs.
