Build a model or prototype of the proposed solution.

Building should include

• using detailed drawings (e.g., paper and pencil, computer-aided design)
• building a simple model
• assessing the model for possible problems
• producing your model or prototype
• testing the model or prototype

• physical testing
• experimenting
• evaluating how well it meets criteria
• evaluating appropriateness of materials
• improving the design.

Process/Skill Questions:

• What is the difference between a model and a prototype?
• What is rapid prototyping?
• What information can be gained from a model or prototype?
• What does one do when the evaluation produces negative results?
• How does one select the best way to test a model or prototype?
• What CAD platforms could be used to build and improve the model?
