So this weekend I am missing out on the local Tartan Day festivities to participate in a cub scout camping trip with my son (I am one of the den leaders). I discussed the idea of wearing my kilt on the trip with the scout leader as a tribute to Tartan Day and also because kilts are the best for hiking. He agreed so long as I was willing to give a 10-15 minute presentation to the scouts. I of course quickly agreed as spreading the gospel of kilting is always a great option.
Here is my question to the group....

I need to be able to give a short history of kilts and tartans to a group of boys that are 7-11 years of age. I can discuss this topic all day long with an adult willing to listen to me that long, but I'd like to be able to both educate as well as entertain the boys. Are there any suggestions as to what points I should touch on? Any I should avoid?

Thanks in advance.
