Metal Ball Expansion Experiment
Thermal volumetric expansion of metals experiment number.
Metal ball expansion experiment. This experiment demonstrates the increase of volume of a metal ball when it is heated. Hold the ball and ring up to the class and show them that the ball does not pass through the ring. Ask the students how the ball could be made to fit through the ring. A metal ball fits through a hole in a ring.
On the end of one is a metal ball. The kit includes two screwdriver like handles. On the end of the other is a ring through which the ball just barely fits. Expanding ball ring thermal expansion.
Perform the experiment by heating the ring and show that the ball does indeed pass through. If the ball is heated or the ring is cooled it does not fit anymore. Heating a metal lid on a glass bottle in order to remove the lid. Thermal expansion science experiments for kids.
Metals undergo thermal expansion as well. Perform the experiment by heating the ring and show that the ball does indeed pass through. Similarly to liquids and gases the volume of solids is also dependent on their current temperature.
