Serial blocked

I've been trying to write the next episode of my serial, "Stephanie's Deal," and I'm having trouble making it interesting. My attempts so far have just felt like filler, merely describing Stephanie's day to day life. She's starting a new school, so for her there's a lot of nervous tension and wonder at meeting new people and learning new things, but I can't seem to get that emotion across to a grownup reader that knows those things aren't that serious. I could introduce some danger of getting found out or romantic entanglements but I don't want to be mean to my character and throw some conflict at her just to make the story exciting.

How do other authors deal with the problem of keeping things worth reading?
