Calling all budding astronomers! Take your star-gazing to a whole new level with this kid-friendly telescope and accompanying journal packed with facts and fun activity prompts.

The classic brass Bar & Gauge apparatus to prove and demonstrate the effects of heating a metal. If the bar is heated or if the gauge is chilled in ice, the bar cannot fit the gauge both in length and in diameter. Unlike the Ball & Ring, the two are not chained together.
