Calling all parents: Today, new episodes of "Sid the Science Kid" begin airing (UNC-TV, 11 am, 2 pm).

If you're new to the show, it's a Jim Henson Company show featuring a vivacious five-year-old and his friends that aims to teach kids about science concepts.

Today's episode is "Slide to the Side." Sid has invented a new dance, The Sid Slide to the Side. It works fine in his socks, but when he puts on his new red sneakers, he can't slide. Thus begins a lesson about friction.

Other lessons this week include a look at elasticity, inertia and force.
