OBJ: Given a lab SWBAT explain how a series circuit differs from a parallel circuit with 70% accuracy.

DN: Review Lab Procedures

ACT: Complete Electrical Circuits Lab write-up. HW: Complete Electrical Circuits Lab write-up and ECL Lab quiz (Q:1-14, scantron); Complete Electricity & Magnetism Activity Sheets; EM Exam, Friday Jan 30 (due to Tomorrow’s Blizzard). If 2 days no school, EM Exam, Monday, February 2.

Conclusion Question #4

• Draw Series Circuit, 1 bulb w/ switch, battery

• Draw Series Circuit, 2 bulbs w/ switch, battery

• Draw Parallel Circuit, 2 bulbs w/ switch, battery

Circuit Symbols

REVIEW RESULTS• Series circuit = one path only• More bulbs added on a series circuit, bulbs dim.• If one bulb goes out, they all go out

• Parallel Circuit = two (or more) paths• Bulbs are brighter in a parallel circuit compared

to a series circuit.• If one bulb goes out, the other bulbs get brighter

(remain on).

• Switch = halts or allows the flow of electrons; turns circuit on and off

• Switch up = open circuit = no flow of electrons• Switch down = closed circuit = flow of electrons
