Sensory Sundial

I work with a group of students who are studying Ancient Rome.  The Ancient Romans told time using a sundial or a water clock.  I chose to adapt the sundial.  
Materials:
Air-dry clay
small paper plates
small rocks
gold glitter (of course)
small craft sticks
glue

Directions:
Push the clay to the edges of the plate.  It does not need to be really thick.  Make a lump in the middle for the stick.  Sprinkle gold glitter on the clay.  Push the glitter into the clay.  Push small rocks around the edges of the clay.  Use glue to add glitter to the craft stick.  Push craft stick in at an angle.  Once the clay dries (at least overnight), tear away the paper plate.

After we finished the sundials, I turned off the lights and used a flashlight to demonstrate how the sundial was used to tell time.  Our sundials were not accurate.
