Circuits (updated) By Richie Rizzonelli

Part of Unit: Fundamentals of Electrical and Electronic Systems

Lesson Plan Overview / Details

This lesson will explore the theory and purpose of a series, parallel, and series-parallel (combination) circuits.

Times

Classroom/Lab
3 Days

Objectives /Goals

Students will learn how to create series, parallel & compound circuits.

Activities in this Lesson

  • I take a picture of a wiring diagram and project it on the screen.  Then, I will demonstrate how to read a wiring diagram. I will utilize the overhead projector to show a series circuit, a parallel circuit, and a combination circuit. I will discuss how the circuit is made and the components necessary to make the circuit work. The circuits will include power, ground, switch, and a load. All of these items will need to be assembled to make the circuit function properly.

    During this session, I will ask the students to follow along by drawing each diagram to use as their reference when they build their circuits. I will inform the students to pay attention because they will be given the opportunity to build these circuits and need to make them function properly. I will have the students in small groups of three or four to brainstorm and utilize critical thinking and problem solving skills to accomplish these tasks.

  • series circuit Lab / Shop

    The students will build a series circuit on an electrical trainer breadboard (GM SET) utilizing jumper wires, light bulb, switch, and a horn. At this point I inform the students that a series circuit will only have one path for current flow. If any one of the items fail, the entire circuit will go into "open circuit" and not function.

  • parallel circuit Lab / Shop

    The students will refer to their diagrams to build parallel circuit on an on electrical trainer breadboard (GM SET ) utilizing jumper wires, three light bulbs, and a switch. I remind them that a parallel circuit has more than one path for current flow and to keep this in mind.

  • The students will refer to their diagrams to build a compound circuit on an electrical trainer (GM SET) and utilize a rheostat and three bulbs. I will tell them that this type of circuit is a combination of a series and a parallel circuit.

  • When the students are done with each type of circuit, we will discuss what they have learned through this exercise. I will tell them that they will have additional time the next day to build more circuits and that they can get creative with the different electrical components.

Assessment

Teacher will monitor students progress while they attempt to build the different circuits and answer any questions that may arise.
