- Includes one bar and one gauge
- Steel bar and gauge with wooden handle
- The metal gauge fits over the bar
- For studying expansion (heat) and contraction (cool)
The basic bar and gauge set includes a metal bar with a wooden handle and a metal gauge with a wooden handle. The gauge fits over the bar and provides an ideal tool for studying expansion (upon heating) and contraction (upon cooling) in a visually and kinesthetically effective manner.
