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.

Everyone knows that applying heat to an object increases its temperature. But what is really going on when the temperature of an object increases? Introduce students to the concepts of expansion and contraction using the Solid Body Expansion Demonstrator.

The unit demonstrates the expansion of metal when heated and its contraction when cooled. When either the ball or ring is heated, the ball will not pass through the ring. When cooled, however, the ball will pass through the ring freely. Comes with triangle support base and semi-circular stand for hands-free demonstration.

What You Get:

Ball and Ring, Triangle Base, Semi-Circular Stand


  • Heating and Cooling
