DescriptionElectricity is a fascinating phenomenon among upper elementary students. From its

interesting history to its shocking characteristics, students are just naturally intrigued by

how electricity works in their everyday lives. Therefore, this end of unit project was

designed to connect students to real world applications of electricity through the

construction of buildings and their wiring. Students will have the opportunity to make Shoe

box simulations of a building of their choice and will wire it for lighting or other electronic

devises. This interactive and inquiry based project will have students utilizing what they

have learned about switches, batteries, and the types of circuits to create an building wired

for electricity. They will also have to plan the layout of their buildings wiring with a

blueprint, and get creative by furnishing their building. The students will practice trial and

error processes in finding the best circuit for their building, will guide their thinking and

problem solving through questions, and in the end, produce a well wired building that

demonstrates how electricity works. Students will work in pairs on this one week project,

broken up into 60 minute segments each day.

Objectives Students will design blueprints of a functional circuit around/throughout their

building.

Students will evaluate the effectiveness of their circuit through trial and errorprocesses.

Students will illustrate their knowledge of circuits by testing several in their modelor blueprint.

Students will support the circuit they chose to use by explaining its function.

Students will create a list of places that they see and use electricity.

Students will discuss the functions of the switch and battery through ademonstration.

Students will compare and contrast their dioramas to the real buildings.

Students will construct a model of a buildings electric wiring including circuits,switches and batteries.

below, brainstorm some of the places and appliances that use electricity.

Place Appliances


4/17

Now think about what we have learned about electricity in this particular semester. What

can you tell me about the following big ideas of electricity? Fill in the boxes with what you

know and use the lines connecting the boxes to say something about how these features are

related or work together.

Circuits Switches

Bulb Brightness

Voltage sources Conductors and insulators


5/17

By now you should be with your lab partner. Share with each other your two graphic

organizers.

Discuss the places and appliances that you listed that were similar as well as the items you

listed that were different or not mentioned by the other.

Did you both have similar descriptions in the boxes for the concepts of electricity? What did

you have that was the same and what did you record that was different about each feature?

Now that we have reviewed what we already know about electricty in our everyday lives as

well as in this unit, please read the following message below for a special assignment.

Hello Electricians,

Knowing your savvy knowledge of electricity and experience with it in youreveryday lives, I have just contracted you to wire my latest project. You will select thebuilding in which you wish to construct and then using two switches, three lightbulbs,two D-cell batteries, wires, and more, you and a partner will work to wire the buildingaccordingly. The building has at least one room, at least one light per room, and at leastone other appliance (that will be represented as a light bulb). To assist you in yourconstruction, you will be given time to blueprint your building and test the circuits thatyou chose for your specific building on these plans. You must have this plan approvedby me, the head contractor before you begin physically wiring your model building(which will be, you guessed it, a shoebox). Toward the end of your project you will alsobe employed by the interior designers to furnish and decorate the space(s). After youhave wired and furnished your entire space, you will present it to the class and convincethem and me that it is the most realistic model by explaining how the circuit functions.Be creative, be realistic and have fun!

Sincerely,

Miss. SellHead Contractor

Brainstorming

With your partner, generate a list of buildings you would possibly like to model. Regardless

of the building type you are required to have at least one light and at least one appliance,

which will represented by a light. Use the planning space below to brainstorm the ideas for

buildings and the three electrical applications within them. You may use your first list of

places and appliances to help you.


6/17

Select the building that you wish to model.Why did you choose this building with these electrical components? How did you select whatelectrical components to add to your building? Answer these questions in your sciencenotebook with the heading My Electric ProjectBlueprinting

Once you have answered these questions you may begin blueprinting your building for

wiring. Many contractors, plumbers, and yes, electricians create blueprints or sketches of

the area that they will be working in or building.

In your blueprint you are to:

1. Draw to scale the dimensions of your shoe box and label with measurements.a. if your shoebox is larger than your blueprint paper, then you must scale it

down to an equal size that fits on the paper

2. Designate the three areas that you will have lighting fixture(s) and an electronicappliance.

3. With the cut outs, arrange a circuit with at least two switches, two batteries and thethree lights to fit into the areas you designated for electricity.

a. Keep in mind where you placed your lighting fixtures and appliance(s)4. If time permits, add in furniture or other decorations to be sure that they will not

interfere with your electrical components.

Your Circuit must meet the following criteria: Both batteries must be connected together in the same location.

Building Electric Applications


7/17

One of the bulbs should be dramatically brighter than the other two bulbs.

One switch must turn off two bulbs

The second switch should turn off one bulb*Think about realistic switch set ups. When you turn on the light switch, does the TV

and overhead light go on?

Cut outs


8/17

Blue Printing Paper


9/17

While you work think about:

The circuit that you chose. Did it meet the needs of your design? Did you have tomodify it or select other circuit?

Where did you put your switches? How will their placement affect how the circuitwill run? Are they in realistic locations?

Where did you put your power source and why? Is it in a practical location?

What revisions did you make to your original layout of electric applications?Use these questions to guide your journal response to the following:

How was blueprinting effective? What obstacles did you encounter while designingthe circuits to meet the buildings layout? How did you problem solve/ what changesdid you make form your original thoughts? Label this page in your journalBlueprinting.

Day 2:

Blueprinting

Today you will be finishing your blueprints. Follow the same procedure from day one and

answer the same question about blueprinting in your science journal if you have not yet

done so.

***Remember, you need to have me approve your blueprint before you can start building

and testing your circuit.

Building and testing your circuit

Once I have approved your plan, you may begin building your circuit with the following

materials:

One or two knife switches

Three miniature bulbs

Three bulb holders

2 d-Cell batteries

2 battery holders

10 connection wires

Masking tape Goggles

*** You must wear your goggles at all times when working with any wires!

Test the circuit to see is all of the lights go on. Does it work? Why or why not? If it does not

work, what can you do to change it?


10/17

Draw your final Circuit in the space provided and answer the questions below in your

science notebook.

What circuit did you choose for your building and why? What revisions (if any) did you maketo your circuit after testing it? Explain why some lights are dimmer than others or if yours allshine brightly, explain this to your reader of how you made this happen. Head the pageresponding to these questions in your science notebook as Circuit test.Day 3:

Installing your circuit

By now you should be done with your blueprint, and testing the circuit model that you

designed specifically for your building of choice.

Once you have tested your circuit, and I have verified that it works, you may install it into

your building. Before you make any drastic alterations to your box, assess where you will

place your circuit by holding it up to the shoebox. You should have considered this whileblueprinting but some adjustments may need to be made (i.e. need shorter or longer

wires).Also remember that everything must be in a realistic location (therefore no lights

should be on the floor, your get the deal).

While you install your circuit consider:

What difficulties did you encounter when installing your circuit?

How is your installation different or similar to your blueprint?


11/17

What is the trouble with having one of the lights represent an appliance (thinklocation in the room compared with the other two lights)

Has the placements of your switches changed? If so why?

Has the placement of you batteries changed? If So why?

Have these questions guide you to answer these questions in your science notebook?How is your model different or similar to the blueprint you made? What difficulties did youencounter when installing your circuit? What changes did you make to your circuit and whybased on the shoe box?

Day 4:

Interior Design

Today you will finish installing you circuits and problem solve to be sure that they function

properly.

Once you have finished this step you may furnish you space according to the building that

you chose.

Think critically about the one or two other electric appliances in your space(s). How are

you going to represent this as you furnish the space? When the light goes on, is that how we

will know that the appliance is in use? Be creative and find a way to demonstrate the

electric phenomenon of this object to us.

As you construct your room, also think about your placement of switches. Are they in

realistic locations? Is your power source hidden like it is in the real building?

Compare and contrast how they space you have created is similar and different from the realbuilding. Do this in the Venn diagram below

Day 5:

Congratulations Electricians! You have created beautiful masterpieces but before youdisplay them to perspective building buyers, you must convince me, the headcontractor, that your building has functioning electric features. In your sciencenotebooks please write me a corresponding letter describing your building and how itselectrical features operate. Please address the following questions in your letter:

What circuit did you choose for your building and why?

How do your switches operate in your circuit? How does your battery operate in your circuit? What are the conductors and insulators in your circuit?

What appliance did you chose to make and how does it fit into your circuit?

Did your Blueprint help you construct? What troubles did you encounter inplanning and installing?

I look forward to hearing about all of your good work. Best of luck!

Head Contractor,Miss. Sell

Once you have complete your building description in your science notebook, please bring

your model, science notebook, and blueprint to the carpet. Be prepared to share what you

wrote and demonstrate for the class how and why your building function electrically

because of the decisions that you made and the troubleshooting you encountered.

Science companion is an excellent and professional resource to enhance your classrooms learningin a variety of scientific areas. In my search on electrical circuits, I came upon this PDF and was

impressed by the variety of detailed lessons. This teachers manual is just a mere digital sample but

of experiments, factual information and activities to do with students on electrical circuits. The citebegins with how to navigate the site which is helpful and then talks about how to effectively use the

materials in this e-packet. Next is a summary of the unit broken up by lesson and overview, science

content, science center, family links, further exploration, and cross curricular connections. Then, theplan explores individual lesson beginning with an overview, key points, the big idea and processskills, standards, goals, assessment options, and benchmarks. Further on are listed the materials,

vocabulary in this lesson , and finally how to teach this lesson with side notes on safety , teachers

notes, and management tips. One of the features of this plan that I really enjoyed too was the time of

reflection and discussion at the end of each lesson. It lists questions teacher can ask students along

with the supplemental materials to record supportive findings. Another great feature of this

resource was the background of this topic for teachers. It is written in such a way that only the

imortatnt information about electrical circuits is pulled out so that teacher can explicitly teach it.

Teachers must be knowledgeable in the topic to best instruct their students of it, thus it was the

perfect addition to a lesson plan. Also included were print out of the supplemental materials, notes

to be put in science note books and diagrams that could be manipulated for a multiple of purposes.

Science companion is just that, the perfect teacher aid when teaching electrical circuits because ofits variety of clear information to the teacher, an instant lesson, and supplementary materials. I

highly recommend trying the digital sample but also looking into downloading or purchasing the

whole series.
