United Scientific Ball & Ring Apparatus – Brass Thermal Expansion Physics Demonstration with Activity Guide
-
Clear Thermal Expansion Demonstration – Brass ball fits through the ring at ambient temperature, then expands when heated to illustrate material behavior with temperature changes.
Durable Brass Construction – High-quality brass components ensure consistent classroom use and reliable comparisons.
Insulated Wood Handles – Lacquered brown handles provide secure handling during heating experiments.
Includes Activity Guide – Lesson-ready instructions included for seamless integration into physics curriculum.
Ideal for Grades 6–12 – Perfectly crafted for middle and high school thermodynamics experiments and demonstrations.
Bring the concept of thermal expansion to life with the United Scientific Ball & Ring Apparatus, an engaging, hands-on tool for physics classrooms. Crafted with precision, this apparatus features a brass ball and brass ring, each mounted on elegantly lacquered wood handles for both durability and aesthetic appeal.
At room temperature, the brass ball slides effortlessly through the ring—demonstrating the metal’s natural dimensions. When heated, the ball expands and temporarily won’t fit, vividly illustrating how heat affects material size. A must-have for middle school to high school science labs, this demonstration helps students visualize thermal principles in a memorable and interactive way. An included activity guide equips educators with structured lesson plans to maximize instructional impact
