(also known as Jim Henson's Sid the Science Kid) is an American half-hour CGI animated series that aired on PBS Kids from September 1, 2008 to March 25, 2013, with a total of 68 half-hour episodes produced over two seasons. The computer generated show is produced by The Jim Henson Company and then-PBS member KCET in Los Angeles, California using the Henson Digital Puppetry Studio. The show is produced by motion capture which allows puppeteers to voice digitally animated characters in real time. Production began in the fall of 2008 with 42 half-hour episodes of Sid the Science Kid having been ordered. The series debuted on PBS Kids along with Martha Speaks on September 1, 2008, with a two-year on-air commitment. The original working title for the series was "What's the Big Idea?" and the central character, Sid, was originally named Josh.KOCE, the current primary PBS member for the Los Angeles area, began co-producing the show after KCET disaffiliated with PBS on December 31, 2010.The main character in the show is Sid, an "inquisitive youngster" who uses comedy to tackle questions kids have about basic scientific principles and why things work the way they do. He tries to answer questions and solve problems with the help of his classmates (May, Gerald, and Gabriela), Teacher Susie, and his family (his mother Alice, his father Mort, his Grandma Rose and his baby brother Zeke). In "Hello Doggie," Sid's Grandma adopts a dog from the animal shelter (which she names Philbert – voiced by Bruce Lanoil, motion captured by Daisy the dog). The conceptual content of Sid is based in national science learning standards, cognitive learning theory, and on the preschool science curriculum, Preschool Pathways to Science. Each week's episodes are built around a single scientific theme or concept.
