Totally Rad (Episode #202)

KQED Kids: Sun, Jan 18, 2015 -- 10:00 PM

The dastardly Hacker (Christopher Lloyd) takes over the Radopolis cybersite, declaring himself King in "Totally Rad," the season premiere of CYBERCHASE. In an effort to dethrone him, the kids challenge the Hacker's extreme team to a winner-take-all skate-off. There's just one catch: high-scoring tricks need as much area as possible and the field keeps mysteriously changing! With Digit ( Gilbert Gottfried) as coach, the kids put on a dazzling display of blading, boarding, and biking, but can they match their performance to the changing arena? The Big Idea: Different shapes bounded by the same perimeter can enclose very different areas. Math Topic: Perimeter/Area.

Size Me Up (Episode #124)

KQED Kids: Sat, Jan 17, 2015 -- 10:00 PM

Hacker plans to launch a new virus at Motherboard - one that will crash her hard drive once and for all so he can take over cyberspace. To stop the kids and Digit from getting in his way, he tricks them into a cybersite from which escape seems impossible. In a confounding juxtaposition of scale and size, the kids first find themselves in a land of giants - then become giants themselves in a land of little people. The kids must cope with these disparities in scale and size, and use their brainpower to escape and warn Motherboard before Hacker can launch his virus. The Big Idea: You can create an exact likeness of something--though one that is a different size--by multiplying the size of every part of your original by the same number.

For the first time ever, the CyberSquad's friend Fluff is participating, and invites his pals Matt, Jackie, Inez and Digit to join him in the impressive Penguin March. They head to the Ice Palace, where the gifts are made and where magic snowflakes are sprinkled on the penguins so they can fly. But Hacker, up to his usual ruinous tricks, doesn't want a happy holiday (let alone happy little borgs) so he creates a giant ditch in front of the Ice Palace and traps all the penguins in its icy depths! The CyberSquad must get the penguins ice-shoes so they can climb out before midnight, but how many do they need? With too many to count, the answer lies in the kids' ability to sample the penguin population to make a close estimate. Can the CyberSquad save the penguins and their favorite holiday too??
