Physics outreach event preparation: Looking for feedback

[nanila]

In about a week, I'm supposed to be opening a "Girls Into Physics" event at a sixth-form college with a 20-25 minute talk. The aim of the day-long event, which includes break-out discussion groups and practical activities, is "to show girls how studying physics at A-level and beyond at university can open up career possibilities that they probably haven't thought of and that it's not just a male industry." The organizers asked me not to use PowerPoint, which I'm okay with as I try not to use PP excessively anyway, but it's challenging trying to prepare. I've attempted to write an outline, but I find I keep thinking of clever ways to phrase things and I start scripting, which is incredibly boring. Anyway, I'm looking for a bit of help here.

I'm planning to structure the talk as follows ( behind the cut. )

Assuming that wasn't Teal Deer for you, please let me know if you feel there's anything I haven't touched on. For those who've known me for a while: Is there a personal experience I've discussed with you that you think I ought to include?

It's been a while since I was a 16-year-old girl. If you are one, know one, play one on telly or have more recently been one than I have, I would really appreciate it if you'd let me know whether you'd find this encouraging and inspirational.
