"Easy Make" Sundials

The programming to create all the sundials on this page was done by Dr. Robert Kellogg. Dr. Kellogg is a physicist and is presently (2005) the treasurer of the North American Sundial Society (NASS). He has given these sundial programs to the NASS to be used as an educational tool. The NASS has given permission to post these sundials at "Sunny Day U". Thank you to Dr. Kellogg and the NASS.

The sundials are made by running individual PowerPoint presentations where all you need to know is the latitude of your location. Each presentation consists of three pages. The first is a page of instructions that should be carefully read. The second is for the sundial that you will be making. The third is a graph of the Equation of Time. You can add some text such as your name or the name of your school. Print the sundial on card stock and it will be easier to use. If you print it on regular paper then you can glue it on cardboard before cutting it out.

Using the PowerPoint presentations you can:

• Make an Octagonal Sundial

• Make a Polar Sundial

• Make an Analemmatic Sundial

• Make a Gnomonic Sundial

The images below are examples of the output from these programs. For more detailed information about these types of sundials please visit The Sundial Primer.
