What to include?

[Piper]

A major determining factor is the age level of the Scouts. My wife has been involved with the Girl Scouts for over 35 years. I've done numerous presentations for school, Scout and other youth groups. I take it this is for their "Thinking Day" event? I played the pipes last year as part of my wife's Troop's presentation. That event brings together girls of all different ages. A good rule of thumb is one minute of attention span per year of age. Regardless of age, I try to keep the information in small, easily absorbed doses, nothing too political, heavy or dark. There's a small book out called "Wha's like us?", unfortunately, the author escapes me, that is kind of a light hearted look at Scottish history. The facts are correct, just presented with a bit of humor.
Several years ago I did a presentation for my oldest granddaughter's preschool class. This was a group of 4 and 5 year olds. I showed and played the practice chanter and the smallpipes in the classroom, then had the teacher take them outside for the a demonstration of the Great Pipes. Following a short tune I handed out kazoos that I had picked up at a dollar store and told the kids we would have a volume contest. Teacher was not terribly happy, the presentation was first thing in the morning, so she was stuck with a classroom full of kazoo tooting kids for the rest of her day.
