Grade school kids, especially, have very little endurance in lecture situations. Older kids seem to be more patient, but any lecturer who babbles on and on can be troublesome. Get the campers up and moving Following a brief lecture, the guest speaker should incorporate within the presentation drills or group work which gets the troops involved. The kids are a tad restless after the initial speech, and they want to move. Station work is acceptable here, and staff should be encouraged to get involved.
Nothing irks a speaker more than seated staff.
Involve them early. They're there to work, and your camp time should not be rest time for them. I've participated as a guest in enough camps to know how grateful speakers are with full support from the camp director and the staff. A few of these camps viewed lecture time as an opportunity to sit and chat or to not be there at all. Speakers need help with their demonstrations, and if the camp crowd is large, staff are significantly important.
