Several PBS Kids and PBS Kids Go! Series will treat, not trick, kids and their parents this month.

"Sid the Science Kid" will air episodes from Oct. 20-24 on what can happen if you eat too many sweets and don't brush your teeth as well as the importance of washing your hands and staying active.

And on Oct. 31, PBS Kids and PBS Kids Go! will air Halloween-themed episodes of "Martha Speaks," "Super Why!," "WordWorld," "Cyberchase," "Arthur" and "Maya & Miguel."

The PBS Kids Web site will invite young ghouls and witches to view streaming video of more Halloween-themed episodes of "Arthur," "Cyberchase," "Martha Speaks," "Fetch! with Ruff Ruffman," "Maya & Miguel," "Animalia" and "Design Squad." Additional activities such as Halloween-themed games, crafts, masks, costume ideas, recipes, e-cards and trick-or-treating safety will be available on the PBS Kids and PBS Parents Web sites.
