Discuss these with your counselor and tell why they are important before you begin your model-making project.
2. Explain the uses for each of the following types of models: architectural, structural, process, mechanical, and industrial. Do research into the different types of materials that could be used in making these models.
3. With your counselor's advice, select a subject from requirement 4 for your model project (no kits). Prepare the necessary plans to the proper scale, a list of materials to be used, and a list of the required tools. This model should be your own original work. Tell why you selected this subject.
4. Do ONE of the following:
   1. Architectural Model
      Build a scale model of a house you select to a scale of 1/4"=1'0" (50:1 metric). Discuss with your counselor the materials you intend to use, the amount of detail required, house outside treatment (finish, shrubbery, walks, etc.) and color selections. After completion of the model, present it to your counselor for approval.
   2. Structural Model
      Build a model showing corner construction of a wood frame building to a scale of 1 1/2"=1'0" (8:1 Metric). All structure shown must be to scale. Cardboard or flat sheet woodstock may be used for sheeting or flooring on the model. Review with your counselor the problems you encountered in gathering the materials and supporting the structure.

   5. Industrial Model
      Build a model of an actual passenger-carrying vehicle to a scale of 1"=1'0" or 1/2"=1'0" (10:1 or 25:1 Metric). Take the dimensions of the vehicle, and record the important dimensions. Draw the top, front, rear, and sides of the vehicle to scale. From your plans, build a model of the vehicle to scale. From your plans, build a model of the vehicle and finish in a craftsmanlike manner. Discuss with your counselor the most difficult part of completing this model.
