I take groups of kids on tours of the grounds and teach them according to their grade level and what the teacher's curriculum is. Usually I do the outdoor trails but sometimes I do the conservatory as well.
I'm also on the burn crew, so I get to set fire to the prairies from time to time. Oddly enough, I don't do any gardening activities there.
My favorite plant to show children is skunk cabbage. I just love the look on thier face when they smell it.
