<p>You could ask local architects if they would like to come talk to you and/or visit their offices. You could hook up with your local historic preservation committee or historical society and see if you could help them. They often have architectural or house tours as fundraisers. You could team up with Habitat for Humanity and help build some houses. You could talk to a local college and see if a professor there would like to give you guys a talk. You could find out if you could build something for a local park (like a shelter or shed) under the supervision of an adult.</p>
