Comment on this resource
The purpose of this resource is to introduce students to the concept that sometimes there is no one "right" answer to a question or measurement. Students learn to be careful when searching for a right answer to questions such as 'What time is it?' by comparing multiple measurements of the time of day. Students gain an intuitive understanding of the characteristics of imperfect measurements. Using different clocks, students simultaneously record the displayed times. The resulting time measurements are converted from minutes and seconds to seconds. These measurements are plotted to illustrate the mathematical techniques of averages and deviations from an average.
