Math, Science Focus of New 'Sesame Street' Season

More than three dozen celebrities, including Nicole Kidman and Robin Williams, athlete Carmelo Anthony and Supreme Court Justice Sonia Sotomayor (SOHN'-ya soh-toh-my-YOR') , are set to appear on the new season of "Sesame Street."

"Sesame Street" begins its 42nd season on PBS on Sept. 26.

PBS said Monday the focus of the preschool educational series will be on science, math and engineering education.

That includes age-appropriate experimentation, including designing a launcher to send Hubert the Human Cannonball over a yard and into a bucket of blue gelatin on the season premiere.

The orange monster Murray will conduct science experiments in a regular feature.

Other celebrities set to make cameos include Mark Ruffalo, Sofia Vergara and Seth Rogen; talk-show hosts Craig Ferguson and George Lopez; and musicians Jay Sean and Bruno Mars.
