Grossology is a great way for kids who love or absolutely dislike science to learn more about and enjoy it. I have been watching Grossology since 2nd grade and know just about all there is to know about this show. There are great role models. Abby, for example, doesn't let anything get in her way (except leeches, but she overcame that fear) and she's very bright. Lab Rat, is highly intelligent and is great in engineering, chemistry, and science. Ty, is funny and serious about his job at the same time. (He's the goofy one of the team).
And the some of the comments below that say that the show has swearing in it and inappropriate themes (and what not), they are wrong. The show does not have any swearing or stuff like that. But, yes, it does mention puberty once. I've watched every episode about 20 times in the past 4 years. I think I would've caught swearing by then. The only thing mentioned on the show that could be called inappropriate is this:
Lab Rat: ...small gassy moon orbitting Uranus.
Ty: Orbitting my what?
So, all in all, Grossology is a great show! Educational, hilarious, and downright gross!
