Marble Runs and Solar Cells

Produced by Solar Spark, this activity allows students to model the energy changes happening inside a photovoltaic cell. In a solar cell, electrons move to make an electrical current. The electrons act like the marbles in a marble run.

Marbles at the top of the run flow downhill through the run to the bottom where an input of energy can get them back to the top again.

When the electrons move through the solar cell, electricity is created, just like the way the marbles move the wheels on the marble run.

The activity can be used to model:
* energy changes
