• Dear Students,• I represent a new company to the Central Florida area. We assist homeowners in

lowering their overall energy costs through the use of solar panels. We would like to see if you could determine what the average single family household in your area would use in energy consumption over the course of a year. Our solar panels are sold in different sizes and are placed on a residence with regard to square footage of the house and total energy consumption.

• We are asking you to build a scale model of a single family home. The model needs to be scale version of a 1500 square foot house. Keep in mind the height, size, and direction the roof faces for proper placement of the solar panels. Please consider the data attached when designing your scale model.

• Remember, we would like have a sketch of your design (a “blueprint”) followed with a written explanation of the steps you took to plan and build your model.

• Thank you for your assistance.• Sunny Dae• CF Solar Panels • 1212 Solar Way• Daytona Beach, FL 32112

Using the data students will create a scale model of their 1500 sq. ft. home.

U.S. Energy Consumption in Single Family Households by Region: 2010-2013 (reported in joules)

Note: Site Energy Consumption is the joules value of energy at the point it enters the home, building, or establishment, sometimes referred to as "delivered" energy.

Consider the dimensions on the Blueprint of 1500 square foot single family home of all sides including the roof and then use the shrinking equation to calculate the size it will be in the model.

In this activity you will make a scale model blueprint.

• What scale factor will you use for blueprint? Scale Factor: ¬¬¬-_________________

• Discuss/write about the mathematical relationship between a full size object, and the scale factor: (Multiply? Divide? Scale factor? Object? Model?)

• Develop some equations for scaling: (Multiply? Divide? Scale factor? Object? Model?)

• Shrinking equation: __________________________________________

• Stretching equation: __________________________________________

Instructions for making a scale model:

• Start by creating a scale model of yourself, and then create the scale model of your single family 1500 square foot home using the same method.

• Refer to the diagram of the 1500 square foot house, consider the dimensions of all sides including the roof and then use your shrinking equation to calculate the size it will be in your model. Use the table provided on the next page to record your work.

• Using blank paper, draw a diagram of your model and label the dimensions.

Make your 2-D model to scale by using your calculations in step 1

• What is being modeled? What part is being measured? Measurement (Don’t forget units!)

Model size (calculated)

• What worked well when creating your blueprint?

• What advice would you give to other students who were doing this project and wanted to avoid problems?

• Did you discover anything interesting while doing this project?
