Pi Day is today (3.14)! Larry Shaw started Pi Day in 1988 when he was a physicist at the San Francisco Exploratorium. Today schools across the country will host Pi Day activities and then have students eat slices of pie. Several wonderful websites are devoted to Pi Day, but probably the best one is the Exploratorium site at: Pi Day.
Cotton gin was patented by Eli Whitney in 1794. It changed the way cotton was raised and processed in the southeastern United States. Prior to the gin, slaves had to hand separate the cotton fibers from cotton seeds and debris. The cotton gin processed the separation ten times faster. More cotton could therefore be played, and unfortunately more slaves would be needed. Children could glean many more details at: http://www.archives.gov/education/lessons/cotton-gin-patent/. Children could watch an animation as to how the cotton gin works at: http://www.eliwhitney.org/cotton.htm.
