Fourth Graders Test Different Types of Circuits


Fourth graders in Mr. Knight's science class recently set up different types of circuits using solar cells.  "Each group had a solar cell that could generate about 1.5V of electricity, enough to run a simple motor," explained Mr. Knight.  Students had to get a motor to run and then test out series and parallel circuits.  "We learned that by using a series with two solar cells, we could combine both solar cells to 3V, but when we connected two solar cells in a parallel circuit the combine voltage stayed at 1.5V.  The parallel was enough to run the motor, but not as fast as using a series circuit," said Mr. Knight.
