as posted in a few other responses, have the members involved in a team building activity that is related in one way or another to FIRST.
For an example, For our teams first project/activity this year, we are having members design and build a robotic arm that can pick up a ping-pong sized ball 1 foot away. The arm is being done in groups, it is brainstormed out, designed on AutoCAD and then they are being built. Allow use of any materials available, this will hopefully help get them interested and get their creativity going.
