The time is one of those concepts that humanity is not fully understood, but we love it. There is a flow of time implies that there is effort in the cosmos. It is that time is change. This is when keychain pocket watch models come to the scene. Think how you would evaluate the concept of time if everything was completely stopped.

So it seems logical to use the keychain pocket watch movement to establish over time. We do from time immemorial for agriculture and other human activities that require sunlight. Creating a sundial is thus a formidable adventure of thought in the movement of the sun setting Teachers who take this idea to the classroom may speak of the meridian of the place,About the keychain pocket watch system and movement Articles cardinal points, real and apparent motion of the star that enlightens us and the famous equation time.

But nothing is learned better than when getting down to the procedure. There are many resources and guides for creating keychain pocket watch models and sundials. Here I present a simple idea that could supplement a class or allow personal adventure to create one. For a basic model, one of the simplest, you require:

-         A quadrant and a style or gnomon. The style should be the inclination of the latitude.

-         Same quadrant.

-         For both, it is very easy to build a clock with the program and Shadows. The same has a free version and two paid versions (expert and pro). But with the free version can create a horizontal or vertical clock.

You can find many problems that are easy to use.  With the free version you can only create flat quadrants. So when starting a new quadrant choose our location in the provided by the program or add a hand. Then choose whether horizontally or vertically and will be ready and have the quadrant.

Its dimensions, colors, number of lines, legends, and other options can be changed. By default the horizontal keychain pocket watch quadrant is 19x16 cm, easy to print on an A4 sheet. Quadrant will be printed and then paste the style and the latter to the former. For this, both the dial and the gnomon will have directions on where to paste the base of the triangle formed by the style, with the letters A and B.

The quadrant is associated with the place because they serve the same for other latitude, so you can print Shadows quadrant information can be located nearby. It is common to see a keychain pocket watch and a column in one side with the information.  Of course, it is not necessary to make it as simple as just described. In any school it could be done easily or a parent to do with your child at home.
