I'm not sure if this directly answers your question, but each year our team plans a field trip where we bring about 30 eighth graders (from "academic enrichment", a creative learning/hands on class) with us to the Connecticut Regional. They come for a few hours on Friday and get to see how exciting the competition is in person by watching matches, touring the pits, talking to teams, and collecting buttons. This is a great way to get students excited about FIRST.

At your meetings, I think the rotation idea will serve you well. Make sure you set up stations that show off the many subteams that are important to your team's success - this way, students can get an idea of everything that goes into the team and see many opportunities for them to find their place. A buddy/group system can also help to make people feel comfortable.
