Mandalas and Geometry
Mandalas are art forms that are usually geometric in nature. Their creators get a sense of calm from making them. This type of pattern is found in many parts of the world.
For extra credit you could research mandalas and write a two page paper on them. Make sure you follow guidelines about not plagerizing the work of others – all quotations must be documented.
For extra credit you might even try drawing a mandala of your own.
