GOOD TIME ON
THE RIVERFRONT It's time for some fun in the sun. Welcome to Washington's first analemmatic sundial. To use it, you need sunshine to create a shadow. To read the time, stand on the middle of the pad, next to the current month (see figure). Then, follow your shadow to the ring of hour points. This sundial is set for daylight savings, so during the winter months subtract an hour from what your shadow shows. This sundial shows true local time, which changes throughout the year due to the Earth's axial tilt and orbit, while your clock shows standard mean time, which is what everyone in a time zone agrees on. Thus, the sundial may not exactly match your watch. Enjoy!!

Thanks to my troop, family, friends, and local companies and organizations who helped with this project.

Scientific Principle(s) being demonstrated: Principle of the sun's projected light upon the surface of the earth, and the tilt of the earth, and position in it's orbit about the sun, creates what we humans call the time of day. This is effected by distance from the sun (seasons) and the earth's ever changing tilt... Briefly explain if the experiment was effective for you. Could it have been better?: Worked perfectly..I even played a little standing in the wrong place to see results. When is the apparatus/experiment available to the public: Available 24/7, in a city park, but also access area for the Missouri River...but daylight hours would be more reasonable.
