Career day presentation?

So, my nephew who is 8 years old has asked that I come to his school for career day. I am a residential carpenter with many years of experience in all phases of construction.

It’s a couple of months away, so I have time to think about it, but I’m open to suggestions.

Bear in mind that I will have about 10 minutes MAX for the presentation, so I can’t set up a work station for the kids or anything too grand.

Also, it’s unlikely that I will be able to bring many tools, even hand tools, due to obvious safety concerns.

Thanks.
