__TOC__

=====Introduction=====

[https://en.wikipedia.org/wiki/Sundial '''Sundials'''] ''(or '''Shadow Clocks''')'' are perhaps the oldest scientific instruments. They are thought to have been developed by the ancient civilisations of [https://en.wikipedia.org/wiki/Babylonia '''Babylonia'''], '''[[:Category:Ancient Egypt|Egypt]]''', '''[[:Category:Ancient Greece|Greece]]''' and '''[[:Category:The Romans|Rome]]'''. They were used by '''[[:Category:The Vikings|Viking]]''' and '''[[:Category:Medieval England|Medieval]]''' navigators and are still in use today.

One of the most common types of sundial is a '''[[Exploring Sundials|Horizontal Sundial]]''' and a fully working model can be constructed using '''[[:Category:Stripwood Technology|Stripwood Technology]]''' materials and techniques. '''Sundials''' are based on the apparent movement of the Sun across the sky. Making a model can lead to an understanding of our [https://en.wikipedia.org/wiki/Solar_System '''Solar System]''' and terms such as '''[[Latitude]]'''.

'''Sundials''' have two basic parts: there is a sloping rod ''(or edge of a plate)'' which casts the shadow and plate, or 'dial', on which the shadow falls to indicate the time. The sloping rod is known as a '''[[Sundials and Gnomons|Gnomon]]'''. The '''[[Sundials and Gnomons|Gnomon]]''' should always point '''North''' ''(in the northern hemisphere)'' and be set at an angle which is equal to the '''[[Latitude]]''' of the '''Sundial's''' location.

=====Preparing the Materials=====

* To make the '''[[Sundials and Gnomons|Gnomon]]''', cut a right-angle triangle out of '''[[Paper and Card|Thick Card]]''' which has the '''Sundial's''' location '''[[Latitude]]''' set as one of the oher two angles.
* Position the card '''[[Sundials and Gnomons|Gnomon]]''' vertically down the centre of a sheet of '''[[Paper and Card|A4 Thick Card]]''' such that the right-angle is uppermost ''(i.e. fix along the [https://en.wikipedia.org/wiki/Hypotenuse '''Hypotenuse'''])''.
* Glue lengths of '''[[:Category:Stripwood Technology|Stripwood]]''' along each side to secure it.
* The '''[[Paper and Card|A4 Thick Card]]''' will form the 'dial' of the completed '''Sundial'''.
