This design brief is appropriate for a group engineering project for second grade on up. It is a great culmination to a unit on government. The use of 1/2 inch sugar cubes allows use of 1/2 inch graph paper to directly apply the design to concept. I add about one inch cube of clay to the project to allow students to top their capitol with the statue of freedom. These capitols are really nice when completed and make great displays for offices or open house.
