Illustrates linear and spherical expansion by heating and contraction by cooling. Mild steel bar 110x12.5mm, length x diameter. Mounted on a rod with wooden handle and a brass gauge 150x38mm with a cutout mounted on a separate wooden handle which just admits the bar lengthways and a hole into which the bar passes endways when cold.

Demonstrates the difference in thermal conductivity of different metals. Consists of five metal rods stainless steel, brass, copper, iron and aluminum connected to a center metal, brass, hub which is mounted on a rod with wooden handle. The five rods have depressions on the ends to hold wax. When the center hub is heated, heat is conducted through the rods and conductivity of heat can be ascertained by the melting of wax.
