Day Length/Moon Phase Locations

Through the course of this project you will collect data on sunrise/sunset, moon rise/moonset times, length of daylight hours, whether daylength is increasing or decreasing and the phase of the moon of a location assigned to you in class either on the 75W meridian of longitude or 40th parallel of latitude. Data will be recorded on a daily basis for 2 weeks. At the end of that time data for the entire class will be recorded for all students to analyze to investigate changes in these values and the impact of this information on the surface of the Earth.

Start by clicking on the location you were assigned on the table below. When recording the times of sunrise/sunset and moonrise/moonset you are to record the local time that is given on the website AND "your time". In order to convert the local time for your location into to our time in Middletown use the table below. For instance "Springfield Il 39.8° N 89.6° W - 1 hour" go to the site for springfield. What ever the time says for sunrise you would subtract 1 hour and record the result as "your time".

When your get to the Weather Underground page for your location scroll down until you see a box that looks like the image below
