Which way do you face a sundial?
Which way do you face a sundial?
Sundials need to point in the direction of True North, and the style (either a sharp straight edge or thin rod, often located at the edge or tip of the gnomon) must be aligned with the Earth’s rotational axis.
How do you make a simple sundial?
Take your plate and plastic straw outside. Put the plate on the ground and poke the straw through the hole you made. Slant the straw slightly toward the line you drew. Carefully rotate the plate so the shadow of the straw lines up with the line you drew.

Where is the best place to put a sundial?

What is the angle of a gnomon?
The gnomon of the vertical sundial makes an angle of 90°–L with the vertical (that is, an angle L with the horizontal), as shown in the side view in Figure 5. In the southern hemisphere, the vertical dial is north-facing. Unlike the equatorial dial, the hour angles are not equally spaced.
How do you make a sundial out of paper plates?
