Opened vs. Closed Circuits Comp. Book page 21 Standards: • GLE 0607. 12. 1 Describe how simple circuits are associated with the transfer of electrical energy. • GLE 0607. 12. 2 Explain how simple electrical circuits can be used to determine which materials conduct electricity.

TODAY’S GOALS • We will know the identify and understand the effects of closed and open circuits. • We will be able to identify and describe series and parallel circuits.

Open vs. Closed Circuits

Open vs. Closed Circuits Closed Circuit • Electrons have a complete path to follow. Open Circuit • The electrons path in the circuit is broken

Opened or Closed? CLOSED OPEN

Opened or Closed? CLOSED OPEN

What is the difference in these two circuits? What kind of lines are these? ONE PATH! MULTIPLE PATHS

LET’S PLAY… THE CIRCLE CIRCUIT GAME

Series vs. Parallel Circuits Comp. Book page 22

SERIES CIRCUIT • These circuits have only one path for electricity to flow. • Examples: Christmas Lights, Flashlight

PARALELL CIRCUIT • These circuits have multiple paths for electricity to flow. • Examples: houses, powerlines
