Geometry is an essential element of home construction and architectural design. Take a moment to write down a few ways in which geometry affects architectural planning. Discussion Questions
What data is necessary to collect in order to understand the role of geometry in architecture?
What spatial perspectives and/or mathematical planes are relevant?
Connecting materials is a fundamental act of home construction. The motions and energy required for construction can be measured with scientific equipment.
Consider the following graphs, excerpted from The Science of Home Constructionfrom Schottenbauer Publishing.
Discussion Questions
What physical action is required to make this particular graph?
How many times is the screwdriver turned?
How many angles is the screwdriver turned each time? Make a table containing the value for each event.
What is the average angle turned by the screwdriver?
What is the total angle turned by the screwdriver?
Over what period of time is the screwdriver turned during each rotation event? Make a table containing the value for each event.
What is the average length of time for a turn of the screwdriver?
What are the minimum and maximum angular velocity values?
What are the minimum and maximum angular acceleration values?
Discussion Questions
What is the maximum real power?
What is the maximum apparent power?
What is the maximum current?
Does it take more power to insert or remove the screw? Why?
Why does removing the screw not take a negative amount of power?

Everyone knows that heat rises, and cool air sinks. But it is obvious only in very extreme weather that these well-known facts affect dwellings with more than one floor. Frigid basements and hot second floors are inefficient, resulting in high electric bills. Consider the following graph, excerpted from The Science of Home Constructionfrom Schottenbauer Publishing.
Discussion Questions
What is the temperature at the basement floor?
What is the temperature at the first floor ceiling?
What is the difference in temperature between basement floor and first floor ceiling?
Why is the graph not a continuous curve?
Is is possible for the information provided to identify temperature at any other vertical height?
Redraw the graph, plotting all known points as vertical height (x-axis) versus temperature (y-axis).
If the thermometer is on the first floor, approximately at shoulder height, what might the temperature measurement be? If necessary, include a range such as 20±2. (Note: The basement has a ceiling height of 10' and the first floor has a ceiling height of 8'.)
Schottenbauer Publishing offers over 8,000 graphs on real-life topics for student learning, collected into topic areas including sports, transportation, construction, environment, music, entertainment/toys, and general physics.
In the United States, local building inspectors ensure that construction follows state regulations set forth in the building code. Site visits and approval processes at specific stages of construction ensure that buildings are safe for the public.
The specific guidelines contained in the building code are based on materials tests, conducteddecades ago by engineers on standard building supplies. A sample materials test demonstrated on hobby supplies is shown in the following graph, excerpted from The Science of Home Constructionfrom Schottenbauer Publishing.

One of the best topics for beginning to discuss home construction is the simple act of picking up a piece of lumber. Consider the following graph, excerpted from The Science of Home Constructionfrom Schottenbauer Publishing.
Discussion Questions
What is the force required to lift the plywood?
Why is the force line jagged?
Why is the initial force not 0?
