Introduction:
Since electric circuits are such an important part of our lives it
is important that we understand how they work. This activity
seeks to answer the essential question "What happens to the
electric charge in household circuits?" This activity covers the
following Georgia Performance or Quality Core Curriculum Standards:
SP5c. Students will determine equivalent resistances in series and parallel circuits.
SPS10c. Students will explain the flow of electrons in terms of series and parallel circuits.
QCC FAC50 Students will identify basic structural and decorative designs.
These Information Literacy Standards are addressed by this activity:
1.
The student who is information literate accesses information
efficiently and effectively. Indicator 1: Recognizes the need for
information
2. The student who is information literate evaluates information
critically and competently. Indicator 4: Selects
information appropriate to the problem or question at hand
3.The student who is information literate uses information accurately
and creatively. Indicator 1: Organizes information for
practical application.

Process:
Step
1: Choose roles within your group.
Each group member will choose one of the following jobs. Remember,
the group's success will depend on how well you accomplish your individual
responsibilities. The member tasks are as follows:
A. General Contractor: Your responsibility will be to design the structure, choose the materials, and assemble them.
B. Electrician: This individual will be in charge of wiring the circuits in the house and making sure that they work.
C. Interior decorator:
This person will be in charge of making the interior of the house
attractive, choosing wall colors, wallpaper, drapes, fixtures, etc.
Step 2: Learn about different type of circuits.
Each group member will use resources below to learn about the different types of circuits.
Step 3: Construct the house.
Together group members will construct, decorate, and wire the house according to the following guidelines:
-
The house dimensions are approximately: 24" by 36" horizontally
or vertically. Foam board or cardboard are both excellent materials for building the house.
- Each house will be wired with 5 different circuits as follows:
- The dining room area must have a chandelier with at least two lights in a
SERIES CIRCUIT with a switch.
- The living room must have one PARALLEL CIRCUIT consisting of a switch and at
least two lights.
- The kitchen must have one COMBINATION CIRCUIT consisting of two
switches and at least three lights.
- The front door must have a doorbell (buzzer) and a switch.
- The bedroom must have a ceiling fan with a motor and switch.

Evaluation.
The score of your project consists of 100 points divided into three parts:
I. Group Project = 60 points
Meeting minimum construction requirements:
Neat house assembly, four rooms, and a porch = 15 pts
Successfully meeting series circuit minimum requirements = 10 pts
Successfully meeting parallel circuit minimum requirements = 10 pts
Successfully meeting complex circuit minimum requirements = 10 pts
Successfully meeting doorbell requirement = 5 pts
Successfully incorporating the motor = 10 pts
II. Individual Project = 20 points
- Drawing and schematic of every circuit combination = 10 pts
- Calculations and measurements of voltage and current = 10 pts
Bonus for creativity and/or ingenuity = 10 pts
III. Electric House WebProject = 20 points
You will design and publish a webpage. This page should contain a description of your project and a picture
of your house. Team members appearance in the picture
is
optional. Members should reflect on the process of creating the
house, describing problems that were encountered and conflicts that
arose. Each website should have at least three links to
related
resources. No unrelated links are allowed i.e. commercial sites,
music,
personal favorites etc.
No webpage may include materials that were created by another person
without written permission to quote such materials by the creator of
such material; this includes text, images, and data
published on the Internet and copyrighted.
- House page with procedure, pictures and suggestions = 20 pts
