Firstly, congratulations! I’m confident that the judges will be just as excited to talk to you as you are to talk to them.
Let’s talk a little bit about the job the judges are doing. They will have read your essay, and they have one 5-7 minute window to talk to you and gather the information they need to decide if you are one of the two semi-finalists at your event that best match the award criteria.
First question: Will your scrapbook help the judges do that job (in a way that reflects well on you)? Well, the scrapbook is part of your overall individual contribution to your team, and it has pictures of your outreach work, so it sounds like a yes. However, you need to be careful not to appear to take credit for the stuff you weren’t involved in. Basically, you are being interviewed for the job of ambassador for and to FIRST. If you use it well, the scrapbook could function as a sort of portfolio showing part of your work.
Next question: Is it up to date? The process of maintaining team history doesn’t end. If you did it once and then moved on without seeing to it that either additional volumes were created or that you or someone else kept this one going, it’s still an achievement, but not quite as strong.
Last question: Will having a prop to point at if you get an appropriate question make you more comfortable in the room or will it be a distraction? Only you can answer that one.
One other note: anything you bring into the room is likely to draw some focus from the judges. If this is the thing you are proudest of, that’s a good thing. If there are other things you’d rather talk about, perhaps not. Five minutes isn’t a lot of time.
Hopefully this helps you to clarify your thinking on this. I don’t know you and I haven’t seen the scrapbook, so I can’t just tell you what to do. Depending on the judges and how you use it, it could either help or hurt you. Whatever you decide, good luck!
Couple of pieces of general advice not related to your question: if you have the opportunity to sit down with a mentor or two and do a practice interview, it will help. Take a couple of deep cleansing breaths right before you walk through the door to the interview room. Remember the judges want you to do well.
