Heat
Wood and Metal Cylinder
To show that metal has a lower specific heat than wood, constructed of wood on one end and hollow metal on the other. One way is to simply let students feel both ends of the cylinder at room temperature, enabling them to see that the metal end is cooler than the wooden end. Another easy demonstration is to wrap paper on both ends and hold the cylinder over a flame for five seconds. The metal end will be relatively unmarked while the wooden end will show scorch marks. Includes instruction manual.

Heat Conductivity Bar Set
A simple, effective apparatus demonstrates the heat conductivity of various metals. Four metals bars (Copper, Aluminum, Brass and Steel) are mounted on a base with a hole for suspension. Every metal bar has same cross-sectional area and its conductivity value is marked on the back of the base. The sensitive temperature indicators are attached to the front of each of the four metal bars. The color of the temperature indicator changes with the change in temperature. Place the bars in a beaker of hot water and compare their relative conductivities. With instructions.

Tea Light Stand
Specially made for classroom experiments, this Tea Light Stand provides a safe and steady platform for tea light candles used as heat sources. Its durable metal frame prevents tipping and keeps the flame shielded, making it ideal for controlled heating in physics demonstrations such as convection, expansion, and heat transfer studies.
Features:
- Designed for use with standard tea light candles.
- Provides stable and secure placement during experiments.
