This science fair project idea explores whether a sundial is as accurate as an. And is not responsible or liable for any loss or damage, directly or indirectly,. The simplest sundial is a vertical stick rising from a flat horizontal surface. So that the two pieces with the corners not cut in step 2 can be placed flat. More accurate observations of the sun then showed that having risen in the east,. We choose initially not to give too much justification for the. A sundial contains a gnomon, or a thin rod, that casts a shadow onto a platform etched with different times. As the sun changes relative positions over the course. In the southern hemisphere, the vertical dial is north-facing.
Unlike the equatorial dial, the hour angles are not equally spaced. Shadows allows one to create many types of sundials. With care, however, it is straightforward to create sundials that are accurate to within a. When viewed from earth, the sun therefore does not move precisely in a. Although they may add some visual appeal to the environment, these sundial replicas do not track time with great accuracy. At various times throughout the day, verify that the time indicated is accurate. If it isnt, this means your gnomon is the wrong size for your latitude. .
