You can get patterns to make an indoor sundial, but if you want to make a project for your school, church, or even for your home, you might want to construct a large outdoor sundial.

First, you will need to find a large, flat area that is in full sun, and from which you can see Polaris, the North Star, in the evening. You will also need a concrete post or some other form that stands about four to five feet tall, and about 12 concrete flagstones.
