Series and Parallel Circuits

Lesson Focus - Demonstrate and discuss simple circuits and the differences between parallel and serial circuit design and functions.

Lesson Synopsis - The Series and Parallel Circuits activity encourages students to test two different circuit designs through the use of series and parallel bulbs. Students work in teams to predict the difference between the two circuit designs, and then build examples of the two different circuits using wires, bulbs, and batteries. After testing several predictions about each circuit type, the groups will compare results and discuss findings.

Age Levels - 8-14.

Objectives
Learn that different circuit designs result in different electrical behaviors.
Learn the difference between series and parallel circuits.
Learn to predict outcomes and draw conclusions.
Learn about teamwork and working in groups.

Lesson Activities - Students perform experiments using two different types of circuit arrangements: series and parallel circuits. Students compare a set up of series and parallel bulbs, make predictions about how the circuit will function, record results, and discuss the circuits as a group.

Anticipated Learner Outcomes - As a result of this activity, students should develop an understanding of:
parallel and series circuits
circuits and current
making and testing predictions
teamwork
