One of the best parts about our trip to the Chesapeake Bay was the lazy days at the beach. Of course, as a parent "lazy" day at the beach meant fun times in the water and sand, not exactly leisurly afternoons of naps and a good beach read. The boys were happy to gather shells, watch the crabs scurry on the sand, build sand castles, and run into the waves, but we had a few other fun things planned as well...
A straight stick and some stones made a sundial. (Simply place stones or shells at the shadow's end every hour or so.)

It is easy to dye sand: Mix water with food dye keeping in mind that the sand will dye lighter than the water color, fill a glass/bucket up 3/4 of the way with sand pour on the dyed water to 1 inch above the sand. Stir it to make sure the all the sand gets wet. Let it set overnight. The next morning, spread the sand out flat in the sun to dry. After a few hours you can make sand art.
The absolute delight of the trip, was the buried treasure, complete with a secret treasure map thanks to my fun, uber creative sister, aka Grand Patti:
