Lesson Plan Originally Created By: Jennifer Davis Westerbeck

Create a Bread Board Series and Parallel Electrical Circuit

Part of Unit: Electrical Plans

Lesson Plan Overview / Details

Students need to complete lesson ONE, TWO and THREE of "Creating Basic Bread Board Circuits" before they start lesson FOUR of "Creating Basic Bread Board Circuits"

This is Lesson FOUR ( Making a Basic Parallel/Series circuit ) of "Creating Basic Bread Circuits"

This is a hands on Project.

In Lesson FOUR, students know how to create a Series circuit and a Parallel, now they will create a Series/Parallel all in one Circuit with a switch.

Students will build a Series and Parallel LED's in one circuit with a switch.

Lesson Time

one to two class periods
55 Minutes

Objectives and Goals

Students will build a Basic Series and Parallel Electrical Circuit with a switch.

Activities in this Lesson

  • Set up for Making a Basic Bread Series and Parallel Circuit - Hooks / Set

    Lesson Four ( A Basic Series and Parallel Circuit) in "Building Basic Electrical Circuits

    Students have completed lesson ONE, TWO, and THREE so they have an understanding of how to build a circuit.


    Students can work in teams of two or independently. NO MORE THAN TEAMS OF TWO

    Visual Aid: Slide #10  "of the power point "Creating Basic Bread Board Circuits".

    Have slide #10  "A Series and Parallel Circuit" up on the screen for everyone to see as they walk in the classroom.

    Supplies: Have your supplies out for students to choose what they need to build their series circuit.

        Students will need:

       1. Their  Engineers Notebook

       2. Bread Board - plastic or wood (your choice) see lesson ONE of "Creating Basic Bread Board Circuits"

       3. Three - 1 inch wide strips of foil, approximently 10 inches long, folded in half length wise (in place of wire)

        4. Three - Christmas lights of any kind (small LEDs)

              I have the lights cut up into a single light with some of the wire stripped on wither side.

              For the Series Circuit they will need two LEDs

        5. 14 - 2 inch straws or  14 - 1 inch nails

              I had a small plastic block with a grid of holes to work with, so I used split up the middle 2 inch long straws for my posts.

             You may need to use the block of wood instead, and use 1 inch nails as posts. Students will pound the nails 1/2 in. into the wood, leaving 1/2 inch or so exposed to wrap the foil around.

       6. Hammer

            If you have to use wood as a bread board you will need a small hammer for students to nail in their posts.

        7. AA Battery

    Storing materials: In lesson ONE I suggested storing all materials in separate bins, this way students can pull their own materials and also put away their materials. The only product I passed out myself is the foil, so students don't waste.

    Students have their materials

    You have slide #10 "Making a Basic Bread Board Circuit" up for students to see

    A Basic Series and Parallel Circuit

    (this is the only slide you will need for this lesson)

    Students will take Cornell notes of slide #10

    (see Lesson #1 to learn about Cornell Notes)

    Lecture:    With the use of a pointer and the ninth slide of the power point, I point out the function of each of the components. Then I trace the flow of the electricity with my pointer, showing the beginning of the electricity flow from the negative end of the battery around to the positive end of the battery. Also, showing how the closed switch allows the electricity to flow,or opening the switch to stop the flow of electricity.

    Checking for understanding: I will take a moment to ask a couple of appropriate questions of random students scattered about the room, about the flow of electricity in a series and parallel circuit with a switch.

    1.  What is a Series Circuit?

    2.  What is a Parallel Circuit?

    3.  What is the difference between a Series Circuit and a Series Parallel Circuit?

    4.  Does the electricity flow from the negative side for the battery or the positive side of the battery?

    5. Do you have to have both the positive side of the battery and the negative side of the battery connected to create a circuit?

    I expect the students to copy all of the directions including the annotated schematic drawing into their engineer's notebook before they get started putting their bread boards together.

    Students will use the series and parallel schematic to build a series and parallel circuit.

    If they don't finish before check-off they disassemble their circuit and try again tomorrow using thier own notes.

    (see lesson one for instructions on check off stamps)

Assessment

Assessment Types:
Rubrics, Journals, Demonstrations, Observations,

Students demonstrate their working model by showing that they followed the schematic exactly and using their switch to light up LED lights, there should be five LED's total. You may need to give students more than one AA battery if the battery is not strong enough to light up all the lights.

I have a check off sheet that has the four basic circuits listed, I stamp off each of the circuits as they finish, by now they should have four stamps.

When they finish the entire assignment, all the circuits are stamped off, I then give them a separate grade for their engineers notes. I am looking for accurate annotated drawings and the notes from the "Making Basic Bread Board Circuits" prepend.

As an alternate a RUBRIC Assessment "Design an Electronic Circuit" can be used to evaluate the student's work..

  • RUBRIC: Design an Electronic Circuit RUBRIC: Design an Electronic Circuit [ View Image ] [ Download Original ] The categories of this assessment includes research, explanation of the circuit operation, schematic drawing layout, completeness of written report, and the oral presentation.
