Apply measuring skills using instrumentation.
DefinitionApplication should include
- measuring linear distance, mass, energy, and power with the appropriate measurement devices
- determining significant digits (number of digits beyond the decimal point to determine accuracy of measurement or tolerance)
- encouraging the use of modern electronic measuring equipment and probes (possibly borrow equipment or ask for guests to demonstrate [e.g., surveying]).
- How does an engineering scale differ from standard-ruler scales?
- Why must engineering measurements be precise?
- What tools are used for the inspection of parts and products?
- What are uses of laser instruments?

The student will investigate and understand how to analyze and interpret data. Key concepts include
- a description of a physical problem is translated into a mathematical statement in order to find a solution;
- relationships between physical quantities are determined using the shape of a curve passing through experimentally obtained data;
- the slope of a linear relationship is calculated and includes appropriate units;
- interpolated, extrapolated, and analyzed trends are used to make predictions; and
- situations with vector quantities are analyzed utilizing trigonometric or graphical methods.
