Connecting Materials Together with Construction Tools

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 Construction **from 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?

Over 8,000 graphs from Schottenbauer Publishing provide additional real-life topics for student learning, including sports, transportation, construction, environment, music, entertainment/toys, and general physics.
