Understanding Scientific MeasurementStreaming Video - 2009
Operating on the premise that the physical world can be described by mathematical relationships, this program uses a simple yet powerful series of experiments to study a specific physical phenomenon-the motion of a steel spring. Viewers learn how to construct equations involving dependent variables, independent variables, and known constants in order to predict and measure acceleration and periods of oscillation. Also illustrated are the most effective ways to graph test results and a typical approach for writing a clear and persuasive report on an experiment-including its aim, apparatus, method, results, analysis, evaluation, and conclusion.
