Hola soy yo Susan Boshoven , a bilingual science teacher with San Francisco Unified School District, and participant in the Exploratorium TI , web science workshop .

On these pages I am presenting a multicultural curriculum unit I have written on the theme of time-keeping.The unit is divided into two subunits: Calendars and Rhythms . In the first subunit titled, Calendar for a Planet , time is explored as something that is marked by astronomical events. The Aztec Sun Stone project is an extension idea which investigates time and the evolutionary process.

Rhythm and Sound ,  written in collaboration with Carlos Araiza , a Latin percussionist and composer, explores rhythm as division of time by sound. The Sound portion of the unit is a series of investigations that can be done with tin drums .
