UP:MA19.GDA.2

Students know:

Techniques for dimensional analysis,
Uses of technology in producing graphs of data.
Criteria for selecting different displays for data (e.g., knowing how to select the window on a graphing calculator to be able to see the important parts of the graph.
Descriptive models .
Attributes of measurements including precision and accuracy and techniques for determining each.

Students are able to:

Choose the appropriate known conversions to perform dimensional analysis to convert units.
Correctly use graphing window and other technology features to precisely determine features of interest in a graph.
Determine when a descriptive model accurately portrays the phenomenon it was chosen to model.
Justify their selection of model and choice of quantities in the context of the situation modeled and critique the arguments of others concerning the same situation.
Determine and distinguish the accuracy and precision of measurements.

Students understand that:

The relationships of units to each other and how using a chain of conversions allows one to reach a desired unit or rate.
Different models reveal different features of the phenomenon that is being modeled.
Calculations involving measurements can't produce results more accurate than the least accuracy in the original measurements.
The margin of error in a measurement, (often expressed as a tolerance limit), varies according to the measurement, tool used, and problem context.
