Teaching trumpet?

I have never played trumpet or any wind-reliant instrument. That's why when I was assigned to teach an example 5 minute trumpet lesson I was at a total loss. I scoured the Internet for resources and asked friends that played what I should do. It was overwhelming. It was supposed to be only a 5 minute lesson, but it was just too much for me.

How could I teach something that I have no idea how to do?

After a while I decided to just jump in and do what I could.

...

So it went well. We didn't have nearly enough time to create sounds. I was trying to rush through to get to the actual sound making because I feel that it's important to get beginners creating music as quickly as possible.

I tried to talk as little as possible to listen to what the student was saying. I felt that the student understand what we were planning to accomplish in the lesson. He was ehtusiastic and knew a lot about the trumpet already.

We were only able to take the trumpet out and learn how to hold it. We also covered how to control the valves. I was hoping to get to blowing through the mouthpiece, putting the trumpet together, and making actual notes. None of that happened.

I've never had an experience like this when I was in primary and secondary school, so I do not have an experience to compare this to. I was teaching what I thought would be the very first lesson and although I felt that I rushed, I still stuck to what I wanted to cover.

It wasn't nearly as bad as I had thought. I was worried about my lack of knowledge, but it wasn't a problem at all. It went by quickly and it was actually fun to try and help a beginner through it.

I've always wanted to learn how to play trumpet. Maybe this is the motivation to get me to take the leap. It would only help me to know the basics of as many instruments as possible.
