PAST THE MINIMUM SUNDIAL PROJECT Minimal project is worth a C or C- at best Make a reasonable sundial, measure ~20 times, simple analysis to get sundial accuracy with error bar Make no mistakes Remember, this is 20% of your course grade Get a higher grade by making improvements, double checks, use multiple methods, Go past the minimal project Make 100 timings that are well spaced over many days Align your sundial on north by two or three different methods Use two or three methods to get the correct altitude that the gnomon points above the horizon Tell me how you corrected for the offset of Polaris from the true north pole? Choose well in what point in the shadow you take as the indicator (recall that your gnomon has a non-zero width) With your data, demonstrate that the time of local noon changes from day-to-day This is called ‘the equation of time’ One two widely separated days, measure many times versus watch times, average the differences, and calculate the uncertainty on the average Changes in the time of local noon will be seen in that the daily average offset will be significantly different from one day to the next Make your comparison between days widely separated in time, at least two weeks
