This would be great. Get in touch if you need any specific information.
The Preservation Resource Center of New Orleans runs educational programs in schools, though I am not sure about how often or exactly what the activities are. With limited staff, they might be open to partnerships for expansion.
From their website:
"Children's Education welcomes grades 4th-12th to participate and view an Architectural History of New Orleans slide show - which impresses upon students the dramatic change in New Orleans' cityscape over time. They will learn about House Types & see the PRC's dramatic "Before and After" slide show - to demonstrate the effects of preservation in action. It can be combined with a visit to the French Quarter."
