2. Essential Question Why are accuracy and precision important? What limits our ability to be pricise?

3. Big Idea Accuracy and precision give validity to your data.

4. You Should Know:  Accuracy compares an experimental value to what is accepted.  Precision describes the degree of exactness of a measurement.  Graphs represent relationships.  The basic SI units for physics are meters, kilograms, and seconds.

5. You should be able to:  Make measurements with accuracy and precision.  Record data using scientific notation and SI units.  Use DA for unit conversions.  Organize and evaluate data and make inferences from data, including the use of tables, charts, and graphs.  Identify and quantify causes and effects of uncertainties in measured data.
